The study was designed to compare Rosuvastatin with Atorvastatin in terms of their efficacy to reduce low-density lipoproteins (LDL-C) in patients with type 2 diabetes mellitus. For this purpose, a cross-sectional analytical study was conducted in the OPD of Nishtar Medical Hospital, Multan, for six months. The study enrolled 66 patients who were consecutively allocated for double-blind therapy with 10mg Atorvastatin (n = 33) and 10mg Rosuvastatin (n = 33) for one month. The doses titration was carried up to four months in certain patients who failed to achieve 1998 European LDL-C level in the first month. A significant number of patients who were given 10mg Rosuvastatin matched the 1998 LDL-C goal in compared to the patients with 10mg dose of atorvastatin at one month (51% vs 46%, p< 0.0001) and at four months (94% vs 88%, p<0.05). Conclusively, Rosuvastatin was significantly more efficacious than Atorvastatin in its ability to reduce LDL-C.

Background : Although vast clinical evidence supports the oxidative CVD hypothesis, little is known on the effects of statins on LDL/HDL oxidative functionality. Therefore, the aim of this study was to evaluate the antioxidative effects of rosuvastatin by monitoring the susceptibility of LDL to oxidation and the antioxidative HDL potential in low-to-moderate CV risk subjects. Methods : 40 adult ambulatory patients (aged 53.8±10.9 years, 27 women and 13 men) were included in the study. Data was collected from patients' records, physical examination, and blood sampling. Subjects were prescribed rosuvastatin at 20mg/day. Traditional risk-factors/indicators, lipid parameters, inflammatory/immune markers, LDL susceptibility to oxidation and HDL antioxidative potential were monitored and statistically analyzed with t-test, Chi-square test, one-way ANOVA, Mann-Whitney, and Kruskal-Wallis tests. Multivariate logistic regression analyses were made. Results were considered significant when p≤0.05. Results : 67% of the patients showed lower susceptibility of LDL to oxidation after rosuvastatin treatment (p=0.03), with no significant effect on baseline LDL oxidation and lag time. All three LDL oxidative indices were seen to be dependent on the subjects' lipid profile, hemoglobin levels and the IL-1α and IL-8 pro-inflammatory marker levels. 53% of the patients showed higher HDL antioxidative capacity after treatment, but without statistical significance (p=0.07). Increased antioxidative potential of HDL with rosuvastatin treatment was more likely in males (OR=9.350; p=0.010), and subjects achieving lower post-treatment CV relative risk levels (higher CV risk reduction) (OR=0.338; p=0.027). Conclusions : This study suggests the need of a comprehensive approach when investigating oxidative stress and LDL/HDL functions, especially in low-to-moderate CVD risk subjects., (© 2022 Ana Vavlukis et al., published by Sciendo.)

Background: The beneficial effect of statins on atherosclerosis and cardiovascular outcomes has been well established. The Measuring Effects on intima media Thickness: an Evaluation Of Rosuvastatin (METEOR) global study demonstrated that a 2-year orally administered treatment with rosuvastatin 40 mg daily significantly slowed the progression of carotid intima-media thickness (CIMT) compared to placebo. The current METEOR-China study is designed to evaluate the effect of rosuvastatin 20 mg daily versus placebo on the progression of atherosclerosis measured by CIMT in asymptomatic Chinese subjects., Methods: This is a phase 3, randomised, double-blind, placebo-controlled, multicentre parallel-group study. Asymptomatic Chinese subjects with a 10-year ischaemic cardiovascular disease (ICVD) risk < 10% will be recruited at 25 study sites. They will be treated with rosuvastatin 20 mg or placebo for 104 weeks. The primary endpoint is the annualised rate of change in CIMT measured by B-mode ultrasonography. Secondary endpoints include the annualised rate of change in CIMT at three different sections of the carotid artery and changes in the serum lipid profile. Safety parameters will also be assessed., Conclusion: The study will evaluate whether rosuvastatin 20 mg slows the progression of CIMT in asymptomatic Chinese subjects at low risk of ICVD., Trial Registration: ClinicalTrials.gov NCT02546323 .

Background: The potential of neuroprotective agents should be revisited in the era of endovascular thrombectomy (EVT) for acute large-artery occlusion because their preclinical effects have been optimized for ischemia and reperfusion injury. Neu2000, a derivative of sulfasalazine, is a multi-target neuroprotectant. It selectively blocks N-methyl-D-aspartate receptors and scavenges for free radicals. This trial aimed to determine whether neuroprotectant administration before EVT is safe and leads to a more favorable outcome., Methods: This trial is a phase-II, multicenter, three-arm, randomized, double-blinded, placebo-controlled, blinded-endpoint drug trial that enrolled participants aged ≥ 19 years undergoing an EVT attempt less than 8 h from symptom onset, with baseline National Institutes of Health Stroke Scale (NIHSS) score ≥ 8, Alberta Stroke Program Early CT score ≥ 6, evidence of large-artery occlusion, and at least moderate collaterals on computed tomography angiography. EVT-attempted patients are randomized into control, low-dose (2.75 g), and high-dose (5.25 g) Neu2000KWL over 5 days. Seventy participants per group are enrolled for 90% power, assuming that the treatment group has a 28.4% higher proportion of participants with functional independence than the placebo group. The primary outcome, based on intention-to-treat criteria is the improvement of modified Rankin Scale (mRS) scores at 3 months using a dichotomized model. Safety outcomes include symptomatic intracranial hemorrhage within 5 days. Secondary outcomes are distributional change of mRS, mean differences in NIHSS score, proportion of NIHSS score 0-2, and Barthel Index > 90 at 1 and 4 weeks, and 3 months., Discussion: The trial results may provide information on new therapeutic options as multi-target neuroprotection might mitigate reperfusion injury in patients with acute ischemic stroke before EVT., Trial Registration: ClinicalTrials.gov, ID: NCT02831088 .

BMS-A is an inhibitor of cholesteryl ester transfer protein and is a highly lipophilic compound (clogP 10.5) with poor aqueous solubility (<0.0001 mg/mL at pH 6.5). The compound exhibits low oral exposure when dosed as cosolvent solution formulations. The purpose of this study was to evaluate lipid-based formulations for enabling high-dose toxicology studies and enhancing toxicology margins of BMS-A in preclinical studies in nonrodent species. The solubility of BMS-A was screened in lipid and cosolvent/surfactant excipients, and prototype formulations were developed. In vitro tests showed that fine/microemulsions were formed after aqueous dilution of lipid formulations, and BMS-A was transferred from oil phase to aqueous phase with enhanced solubility following lipid digestion. When dosed in dogs at 200 mg/kg, a Gelucire-based formulation exhibited more than 10-fold higher exposure compared to the solution formulation and was thus selected for toxicology studies in dogs. For monkeys, an olive oil formulation was developed, and the exposure was about 7-fold higher than that from the solution. In summary, lipid-based drug delivery could be applied in early stages of drug discovery to enhance oral exposure and enable preclinical toxicology studies of highly lipophilic compounds, while facilitating the candidate selection of a molecule which is more specifically designed for bioperformance in a lipid-based drug delivery strategy., (Copyright © 2018 American Pharmacists Association®.

Takotsubo cardiomyopathy is a disorder characterized by left ventricular apical ballooning with preceding emotional and/or physical stressors. This condition is also an important differential diagnosis of acute coronary syndrome. We herein describe a case of Takotsubo cardiomyopathy, a significant clinical phenomenon, triggered by delayed-onset rhabdomyolysis following the administration of long-term statin treatment, without any preceding stressors or changes in the patient's medical condition, in association with complaints of non-specific muscle-related symptoms. Although an electrocardiogram showed remarkable ST-segment elevation, a careful reading of the electrocardiogram findings revealed the features of Takotsubo cardiomyopathy. Withdrawing the statin therapy improved the patient's cardiac function.

The authors report a case of transient azoospermia following hydroxymethylglutaryl-coenzyme A reductase (HMGCR) inhibitor rosuvastatin medication for hypercholesterolemia. While a primary infertile couple with oligoasthenospermia was preparing for an in vitro fertilization program, the male partner had been diagnosed with hypercholesterolemia in a medical check-up and prescribed four-week oral administration of rosuvastatin. No motile spermatozoa were found in the ejaculated semen and urine on the day of follicular aspiration. Azoospermia was confirmed by reexamination in weeks 3 and 7. Spermatozoa appeared in the ejaculated semen in two weeks of drug withdrawal. In week 16, the sperm count and motility increased to the level where intracytoplasmic sperm injection was available.

Background: Venous thromboembolism (VTE) is common in clinical practice. The efficacy of statins in the primary prevention of VTE remains unproven. This is an update of the review first published in 2011., Objectives: To assess the efficacy of statins in the primary prevention of VTE., Search Methods: For this update the Cochrane Peripheral Vascular Diseases (PVD) Group Trials Search Co-ordinator searched the Specialised Register (last searched February 2014) and CENTRAL (2014, Issue 1)., Selection Criteria: Randomised controlled trials (RCTs) that assessed statins in the primary prevention of VTE were considered. The outcomes we evaluated were the rates of VTE, cardiovascular and cerebrovascular events, death and adverse events. Two authors (L Li, JH Tian) independently selected RCTs against the inclusion criteria. Disagreements were resolved by discussion with a third author (KH Yang)., Data Collection and Analysis: Data extraction was independently carried out by two authors (L Li, JH Tian). Disagreements were resolved by discussion with a third author (PZ Zhang). Two authors (L Li, JH Tian) independently assessed the risk of bias according to a standard quality checklist provided by the PVD Group., Main Results: For this update we included one RCT with 17,802 participants that assessed rosuvastatin compared with placebo for the prevention of VTE. The quality of the evidence was moderate because of imprecision, as the required sample size for the outcomes of this review was not achieved. Analysis showed that when compared with placebo rosuvastatin reduced the incidence of VTE (odds ratio (OR) 0.57, 95% confidence interval (CI) 0.37 to 0.86) and deep vein thrombosis (DVT) (OR 0.45, 95% CI 0.25 to 0.79), the risk of any (fatal and non-fatal) myocardial infarction (MI) (OR 0.45, 95% CI 0.30 to 0.69), and any (fatal and non-fatal) stroke (OR 0.51, 95% CI 0.34 to 0.78). There was no difference in the incidence of pulmonary embolism (PE) (OR 0.77, 95% CI 0.41 to 1.46), fatal MI (OR 1.50, 95% CI 0.53 to 4.22), fatal stroke (OR 0.30, 95% CI 0.08 to 1.09) or death after VTE (OR 0.50, 95% CI 0.20 to 1.24). The incidence of any serious adverse events was no different between the rosuvastatin and placebo groups (OR 1.07, 95% CI 0.95 to 1.20)., Authors' Conclusions: Available evidence showed that rosuvastatin was associated with a reduced incidence of VTE, but the evidence was limited to a single RCT and any firm conclusions and suggestions could be not drawn. Randomised controlled trials of statins (including rosuvastatin) are needed to evaluate their efficacy in the prevention of VTE.

Objective: To compare the efficacy and safety of atorvastatin, rosuvastatin and xuezhikang capsule in elderly., Methods: A total of 314 60-to-94-year-old (average (73.6 ± 7.9) years old) patients who were given different doses and types of statins were divided into three groups: the atorvastatin group (108 patients), the rosuvastatin group (104 patients) and the xuezhikang capsule group (102 patients). The serum TG, TC, LDL-C, HDL-C,ALT and CK were examined before and after the treatment which lasted for at least 4 weeks. All patients were divided into moderate risk group (13, 12 and 21 patients respectively in 3 groups); high risk group (40, 44 and 48 patients respectively in 3 groups) and very high risk group (55, 48 and 33 patients respectively in 3 groups ) according to guidelines on prevention and treatment of dyslipidemia in chinese adults (2007 version). The rate of reaching target goal and the dose when reaching target levels in different risk stratification groups were calculated and compared., Results: Serum TC, LDL-C and non-HDL-C were significantly reduced after the 4-week-treatment in all the three groups (P < 0.01). Serum LDL-C level before and after treatment were (3.14 ± 0.78)mmol/L vs. (2.14 ± 0.65)mmol/L in atorvastatin group (the arevage dose was (16.4 ± 4.8)mg/d), (2.92 ± 0.77)mmol/L vs. (1.96 ± 0.55)mmol/L in rosuvastatin group (the arevage dose was (8.7 ± 3.0) mg/d), and (2.70 ± 0.62)mmol/L vs. (2.16 ± 0.61) mmol/L in xuezhikang capsule group (the arevage dose was (0.9 ± 0.3) g/d ). Among all the three groups of patients, the cases of reaching target levels of LDL-C were 13, 11 and 20 in patients at moderate risk, were 38(95.0%), 38(86.4%) and 40 (83.3%) in patients at high risk, and were 22(40.0%), 30(62.5%) and 17(51.5%) in patients at very high risk. There were no statistical differences in the rate of reaching target levels of LDL-C, non-HDL-C and TC in the three groups and at different risks (P > 0.05). One patient in the atorvastatin group showed ALT level elevation >3 times of the upper limit of normal value, there was no patient with CK level elevation >5 times of the upper limit of normal value., Conclusion: Atorvastatin, rosuvastatin and xuezhikang capsule at low dose and/or standard dose are effective and safety in elderly patients.

Rosuvastatin is the most potent 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase inhibitor commercially available to lower low-density lipoprotein cholesterol. Rosuvastatin has been associated with several adverse effects, including rhabdomyolysis and arthralgias. Here, we report an unusual adverse effect occurring on treatment with rosuvastatin, a 'continuous sensation of coldness'. A 60-year-old man began experiencing this peculiar feeling shortly after introduction of rosuvastatin treatment. The gentleman had to wear extra pair of socks and cover himself with blankets while reading, even during summer with surrounding temperature above 30°C. The abnormal sensation persisted for the 26 months during which he was treated with rosuvastatin, and disappeared within a week after discontinuing treatment. Physical examination, including thorough neurological examination, was entirely normal, as were haematological and biochemical parameters. While the pathophysiology of this phenomenon remains unknown, we hope that this case will encourage others to report similar symptomatology, perhaps enabling to gain more insight on the condition., (2014 BMJ Publishing Group Ltd.)

Purpose: Statins increase the incidence of new onset diabetes. Prolonged statin therapy upregulates PTEN expression. PTEN levels are also elevated in diabetic animals. Activation of protein kinase A by cAMP decreases PTEN expression. We assessed whether prolonged treatment with rosuvastatin (ROS) induces glucose intolerance by upregulating Phosphatase and Tensin Homologue on Chromosome 10 (PTEN) in mice receiving normal (ND) or Western Diet (WD) and whether concomitant treatment with cilostazol (CIL, a phosphodiesterase-3 inhibitor) attenuates the effects., Methods: PTEN(loxp/cre) or PTEN(+/-) mice received ND or WD without or with ROS (10 mg/kg/day). Wild-type mice received ND or WD without or with ROS, CIL (10 mg/kg/day), or ROS+CIL for 30 days. Fasting insulin and glucose tolerance test were measured as well as PTEN and P-AKT levels in skeletal muscle., Results: Serum glucose after intraperitoneal injection of glucose was higher in PTEN(loxp/cre) mice receiving WD or ROS and especially WD+ROS. Levels were lower in PTEN(+/-) mice compared to PTEN(loxp/cre) in each treatment group. CIL decreased glucose levels in mice receiving WD, ROS and their combination. Insulin levels were higher in the WD+ROS group. CIL decreased insulin in mice receiving WD+ROS. WD, ROS and especially their combination increased PTEN and decreased P-AKT levels. CIL attenuated the effect of WD, ROS and their combination., Conclusions: Long-term ROS can induce diabetes by upregulating PTEN. CIL attenuates these changes. Partial knockdown of PTEN also ameliorates ROS-induced insulin resistance. Further studies are needed to assess the effects of increasing cAMP levels to prevent the induction of diabetes by statins.

Background: Statin therapy is a cornerstone therapy for secondary prevention after acute coronary syndrome (ACS). However, the use of these drugs can be limited by side effects, mainly muscular pain. Ezetimibe is a newer lipid-lowering agent, with fewer side effects., Aims: The present study was designed to compare a commercially available association of ezetimibe and simvastatin (E-S) to high dose Rosuvastatin on cholesterol and muscular enzyme levels and occurrence of muscular pain., Methods: All consecutive ACS statin-naïve patients with LDL cholesterol (LDL-C)>100mg/dL randomly received either high dose statin (Rosuvastatin 20mg) or E-S 10/40-mg. All patients had one-month follow-up with biological testing and clinical examination. We compared the two groups on the biological efficiency and incidence of muscular pain., Results: One hundred and twenty-eight patients were randomized; 64 received E-S and 64 Rosuvastatin. In the two groups, the lowering of LDL-C level (Δ=51%) at one month was significant (P<0.01) without any difference in the rate of lowering on LDL-C or HDL-C suggesting that E-S is as effective as high dose Rosuvastatin (P=0.77 and P=0.99). The rate of patients reaching the objective of LDL-C<100mg/dL (45%) and LDL-C<70mg/dL (51%) was not different in the two clusters (P=0.65). Incidence of muscular pain was 15% higher in patients treated with Rosuvastatin (P=0.01) without any difference on CPK level (P=0.6)., Conclusion: Using an association of E-S in an effective alternative strategy to high dose Rosuvastatin with a lower incidence of muscular pain, which might impact adherence to medication after ACS., (Copyright © 2014 Elsevier Masson SAS.

Aim: The aim was to evaluate clinical risk factors associated with myotoxicity in statin users., Methods: This was a cohort study of patients prescribed a statin in UK primary care practices contributing to the Clinical Practice Research Datalink. Outcomes of interest were creatine phosphokinase (CPK) concentrations and clinical records of rhabdomyolysis., Results: The cohort comprised 641,703 statin users. Simvastatin was most frequently prescribed (66.3%), followed by atorvastatin (24.4%). CPK was measured in 127,209 patients: 81.4% within normal range and 0.7% above four times ULN CPK compared with normal CPK (OR 1.28, 95% CI 1.01, 1.60). Rosuvastatin users had higher risk of >four times ULN CPK (OR 1.62, 95% CI 1.22, 2.15) as did patients with larger daily doses of other statin types. A recent clinical record of myalgia was associated with an increased OR of >four times ULN CPK (OR 1.73, 95% CI 1.37, 2.18). In patients who were rechallenged to statins and had repeat CPK measurements after >four times ULN CPK abnormalities, 54.8% of the repeat CPK values were within normal range, 32.1% between one to three times and 13.0% >four times ULN., Conclusions: The frequencies of substantive CPK increases and rhabdomyolysis during statin treatment were low, with highest risks seen in those on large daily doses or interacting drugs and on rosuvastatin. CPK measurements appeared to have been done in a haphazard manner and better guidance is needed., (© 2014 The British Pharmacological Society.)

The effects of high-potency statins on renal function are controversial. To address the impact of statins on renal morpho-functional aspects, normotensive young mice were treated with rosuvastatin (Rvs). Moreover, because statins may impair mitochondrial function, mice received either dietary supplementation with an amino acid mixture enriched in essential amino acids (EAAm), which we previously demonstrated to increase mitochondrial biogenesis in muscle or an unsupplemented control diet for 1 month. Mitochondrial biogenesis and function, apoptosis, and insulin signaling pathway events were studied, primarily in cortical proximal tubules. By electron microscopy analysis, mitochondria were more abundant and more heterogeneous in size, with dense granules in the inner matrix, in Rvs- and Rvs plus EAAm-treated animals. Rvs administration increased protein kinase B and endothelial nitric oxide synthase phosphorylation, but the mammalian target of rapamycin signaling pathway was not affected. Rvs increased the expression of sirtuin 1, peroxisome proliferator-activated receptor γ coactivator-1α, cytochrome oxidase type IV, cytochrome c, and mitochondrial biogenesis markers. Levels of glucose-regulated protein 75 (Grp75), B-cell lymphoma 2, and cyclin-dependent kinase inhibitor 1 were increased in cortical proximal tubules, and expression of the endoplasmic reticulum-mitochondrial chaperone Grp78 was decreased. EAAm supplementation maintained or enhanced these changes. Rvs promotes mitochondrial biogenesis, with a probable anti-apoptotic effect. EAAm boosts these processes and may contribute to the efficient control of cellular energetics and survival in the mouse kidney. This suggests that appropriate nutritional interventions may enhance the beneficial actions of Rvs, and could potentially prevent chronic renal side effects.

Introduction: Oxidative stress plays an important role in atherosclerosis. Both F2-isoprostane (8-iso-PGF2a) and oxidized low-density lipoprotein (ox-LDL) have emerged as biomarkers of oxidative stress and have been proposed as useful biomarkers that could potentially be used as indicators of cardiovascular disease., Methods: This is a prespecified analysis of a prospective, randomized, open-label, blinded endpoint (PROBE) study (ClinicalTrials.gov identifier: NCT01010516). Patients (N = 100) with mixed dyslipidemia on a standard statin dose (10-40 mg simvastatin or 10-20 mg atorvastatin or 5-10 mg rosuvastatin) who had not achieved lipid targets were randomized to switch to the highest dose of rosuvastatin (40 mg/day) or to add-on-statin extended release nicotinic acid (ER-NA)/laropiprant (LRPT) (1000/20 mg/day for the first 4 weeks followed by 2000/40 mg/day for the next 8 weeks) or to add-on-statin micronized fenofibrate (200 mg/day) for a total of 3 months. Levels of plasma and urine F2-isoprostane and plasma ox-LDL were assessed at baseline and 3 months later., Results: Plasma F2-isoprostane levels decreased similarly in all groups. On the other hand, both ox-LDL and urine F2-isoprostane levels decreased similarly in the add-on ER-NA/LRPT and rosuvastatin monotherapy group, while a less pronounced decrease was observed in the add-on fenofibrate group., Conclusions: All treatment interventions reduced the concentration of the assessed oxidative stress markers, but the reduction was more pronounced in the add-on ER-NA/LRPT and rosuvastatin monotherapy groups, compared with add-on fenofibrate. Specifically designed studies should address the abovementioned risk factors modulation in terms of cardiovascular risk., (© 2014 John Wiley & Sons Ltd.)

Rosuvastatin has been marketed for approximately a decade. In this review we critically discuss available evidence on the benefits and risks from its use. In clinical trials using rosuvastatin, 'lowest is best' was relevant for on-treatment low-density lipoprotein cholesterol levels. Targeting levels <50 mg/dl was associated with the greatest decrease in vascular morbidity/mortality in the primary prevention setting. Also, such reduction can induce atherosclerosis regression without increasing the risk of adverse effects. Pooled data suggest that the safety profile of rosuvastatin is not different from that of other statins. It was estimated that rosuvastatin-associated absolute hazards of muscle-, liver- and renal-related adverse effects are lower than the corresponding vascular benefits in moderate vascular risk individuals. However, these data are subject to biases and need confirmation on a prospective basis. Significant liver enzyme elevations are rare. These often imply underlying non-alcoholic fatty liver disease (NAFLD), which is associated with increased vascular risk. Rosuvastatin can improve biochemical biomarkers and histological score of NAFLD. Whether this benefit is associated with vascular risk reduction should be assessed by prospective studies. Both chronic kidney disease and albuminuria independently predict vascular morbidity and mortality. Rosuvastatin improved the estimated glomerular filtration rate and decreased albuminuria in patients with moderately impaired kidney function. Also, vascular morbidity and mortality might be reduced in these patients. The same was not relevant in end-stage renal disease. Rosuvastatin-induced proteinuria appears to be of tubular origin, not relating to kidney injury. Rosuvastatin increases the risk of new-onset diabetes by dose-dependently impairing insulin sensitivity. Obese individuals with prediabetes appear to be predominantly affected. However, absolute vascular benefits of rosuvastatin may counterbalance this risk. Rosuvastatin is effective for the prevention and management of atherosclerotic vascular disease. Individualization of its use can maximize benefits and reduce the risk of adverse effects.

Objective: This case-control study investigated the association between statin use and liver injury using Taiwan's National Health Insurance Research Database., Methods: Our study subjects included 4165 cases (patients who had been admitted with a primary diagnosis of liver injury between 2002 and 2009) and 16 660 age-matched, sex-matched and index date-matched controls. Multivariable conditional regression models were used to estimate the association between statin use and liver injury., Results: Users of statins were not associated with risk of liver injury (adjusted odds ratio [aOR] 1.04; 95% confidence interval [0.90-1.19]) when compared with nonusers. Nevertheless, a higher dose of statin (≥1 defined daily dose; aOR 1.55 [1.14-2.11]) and use of rosuvastatin before event of liver injury (aOR 1.38 [1.03-1.85]) were significantly associated with liver injury., Conclusions: This population-based study extends previous evidence by exploring the potential association between statins use and risk of liver injury. Overall, we found that statin was not associated with risk of liver injury. Nevertheless, special concern should be paid to those who used statin ≥1 defined daily dose and rosuvastatin., (Copyright © 2014 John Wiley & Sons, Ltd.)

Background: Dyslipidemia is a risk factor for premature cardiovascular morbidity and mortality in renal transplant recipients (RTRs). Pharmacotherapy with mTOR inhibitors aggravates dyslipidemia, thus necessitating lipid-lowering therapy with fluvastatin, pravastatin, or atorvastatin. These agents may not sufficiently lower lipid levels, and therefore, a more potent agent like rosuvastatin maybe needed., Methods: We have aimed to assess the lipid-lowering effect of rosuvastatin as compared with fluvastatin in RTR receiving everolimus. Safety was assessed as the pharmacokinetic (PK) interaction potential of a rosuvastatin/everolimus combination in RTR. A 12-hour everolimus PK investigation was performed in 12 stable RTR receiving everolimus and fluvastatin (80 mg/d). Patients were then switched to rosuvastatin (20 mg/d), and a follow-up 12/24-hour PK investigation of everolimus/rosuvastatin was performed after 1 month. All other drugs were kept unchanged., Results: In RTR already receiving fluvastatin, switching to rosuvastatin further decreased LDL cholesterol and total cholesterol by 30.2±12.2% (P<0.01) and 18.2±9.6% (P<0.01), respectively. Everolimus AUC0-12 was not affected by concomitant rosuvastatin treatment, 80.3±21.3 μg*h/L before and 78.5±21.9 μg*h/L after, respectively (P=0.61). Mean rosuvastatin AUC0-24 was 157±61.7 ng*h/mL, approximately threefold higher than reported in the literature for nontransplants. There were no adverse events, and none of the patients had or developed proteinuria., Conclusion: Rosuvastatin showed a superior lipid-lowering effect compared to fluvastatin in stable RTR receiving everolimus. The combination of everolimus/rosuvastatin seems to be as safe as the everolimus/fluvastatin combination.

Background: In the acute respiratory distress syndrome (ARDS), inflammation in the lungs and other organs can cause life-threatening organ failure. Inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase (statins) can modulate inflammatory responses. Previous observational studies suggested that statins improved clinical outcomes in patients with sepsis. We hypothesized that rosuvastatin therapy would improve clinical outcomes in critically ill patients with sepsis-associated ARDS., Methods: We conducted a multicenter trial in which patients with sepsis-associated ARDS were randomly assigned to receive either enteral rosuvastatin or placebo in a double-blind manner. The primary outcome was mortality before hospital discharge home or until study day 60 if the patient was still in a health care facility. Secondary outcomes included the number of ventilator-free days (days that patients were alive and breathing spontaneously) to day 28 and organ-failure-free days to day 14., Results: The study was stopped because of futility after 745 of an estimated 1000 patients had been enrolled. There was no significant difference between study groups in 60-day in-hospital mortality (28.5% with rosuvastatin and 24.9% with placebo, P=0.21) or in mean (±SD) ventilator-free days (15.1±10.8 with rosuvastatin and 15.1±11.0 with placebo, P=0.96). The groups were well matched with respect to demographic and key physiological variables. Rosuvastatin therapy, as compared with placebo, was associated with fewer days free of renal failure to day 14 (10.1±5.3 vs. 11.0±4.7, P=0.01) and fewer days free of hepatic failure to day 14 (10.8±5.0 vs. 11.8±4.3, P=0.003). Rosuvastatin was not associated with an increased incidence of serum creatine kinase levels that were more than 10 times the upper limit of the normal range., Conclusions: Rosuvastatin therapy did not improve clinical outcomes in patients with sepsis-associated ARDS and may have contributed to hepatic and renal organ dysfunction.

Background: The Japan Atherosclerosis Society's 2007 Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases (JAS2007GL) advocate reducing LDL cholesterol (LDL-C) to target levels in patients with dyslipidemia, but achievement rates are frequently unsatisfactory even in the presence of lipid-lowering therapy. This multicenter, open-label, randomized, parallel-group study compared the efficacy of rosuvastatin and atorvastatin on JAS2007GL LDL-C goals in Japanese patients not achieving their target goal with atorvastatin treatment., Methods: The study involved 20 clinical institutes in Japan (Kishiwada Atherosclerosis Prevention Study [KAPS] Group). Patients with category II or III risk of coronary artery disease (CAD), or those with a history of CAD (secondary prevention), who had not achieved their JAS2007GL LDL-C goals during treatment with atorvastatin for at least 4 weeks were switched either to rosuvastatin 5 mg/day (from atorvastatin 10 mg/day) or rosuvastatin 10 mg/day (from atorvastatin 20 mg/day) (n = 75) or continued to receive atorvastatin (n = 77). The primary endpoint was achievement of LDL-C goals at 3 months. The main secondary endpoint was achievement of LDL-C goal + high-sensitivity C-reactive protein level <1.0 mg/L at 3 months., Results: Achievement rates for the primary endpoint were 49.3% in the rosuvastatin group and 31.7% in the atorvastatin group (P = 0.022). Achievement rates for the main secondary endpoint were 40.0% in the rosuvastatin group and 20.8% in the atorvastatin group (P = 0.010). Rosuvastatin and atorvastatin were both well tolerated in this study., Conclusions: Rosuvastatin is a useful treatment option for Japanese patients who are not achieving their JAS2007GL LDL-C goal with atorvastatin., (© 2014 John Wiley & Sons Ltd.)

Background: There is no widely accepted treatment for non-alcoholic fatty liver disease (NAFLD) or its advanced form, non-alcoholic steatohepatitis (NASH)., Methods: We administered rosuvastatin (10 mg/day) for 1 year in patients with metabolic syndrome (MetS), NASH on liver biopsy and dyslipidaemia (but without diabetes or arterial hypertension). Patients also received lifestyle advice., Results: We report preliminary results for 6 patients. The second biopsy (at the end of the study) showed complete resolution of NASH in 5 patients, while the 6(th), which had no improvement, developed arterial hypertension and substantial rise in triglyceride levels during the study. We suspect alcohol abuse despite advice to abstain. Serum alanine transaminase (ALT) and aspartate transaminase (AST) activities were reduced by 76 and 61%, respectively (p < 0.001 for both), during treatment, while γ-glutamyl transpeptidase (γ-GT), and alkaline phosphatase (AP) showed smaller non significant reductions. Fasting plasma glucose and glycated haemoglobin (HbA1c) were significantly reduced (p<0.05). Lipid values were totally normalised and liver ultrasonography showed a complete resolution of NASH in 5 patients. Body mass index and waist circumference remained unchanged during the study. Thus, changes in liver pathology and function should be attributed to treatment with rosuvastatin. A substantial limitation of the study is the small number of patients., Conclusions: These preliminary findings suggest that rosuvastatin could ameliorate NASH within a year of treatment in MetS patients with dyslipidaemia.

Rosuvastatin has been used for treatment of dyslipidaemia and metabolic syndrome, but the efficacy has not yet been tested in men with late-onset hypogonadism (LOH). To assess and compare the efficacy and safety of rosuvastatin in men with dyslipidaemia with LOH and non-LOH, a retrospective study was conducted in patients who received rosuvastatin 10 mg day(-1) from the men's health clinic. The primary endpoint was the change in low-density lipoprotein (LDL)-cholesterol (C) after 24 weeks of treatment. A total of 145 dyslipidaemic patients eligible for rosuvastatin treatment were enrolled and divided into LOH group (45.52%) and non-LOH (54.48%) group. There were favourable changes in the lipid profiles. In the LOH group whose serum testosterone had been raised by testosterone administration, the favourable changes of the lipids were of similar magnitude as in the non-LOH group. The percentage of patients reaching the target goal (LDL < 100 mg dL(-1) ) did not differ significantly between the group of non-LOH and LOH men treated with testosterone. Side effects were noted in 1/145 men. It is concluded that rosuvastatin was safe and effective in lowering low-density lipoprotein cholesterol in both non-LOH and LOH dyslipidaemic patients whose serum testosterone levels had normalised., (© 2013 Blackwell Verlag GmbH.)

In a comparative aspect, the dynamics of indices of lipidogram, functional state of liver and level of C-reactive of protein have been analyzed in 79 patients with myocardial infarction in combination with non-alcoholic steatohepatitis, who received a 9-months treatment by rosuvastatin of 20 mg, atorvastatin of 80 mg, as well as rosuvastatin of 10 mg, atorvastatin of 40 mg in combination with ursodeoxycholic acid (UDCA). The obtained results show the equivalent of hypolipidemia effectiveness of all investigated courses of statinotherapy with the benefit of rosuvastatin of 20 mg in increase of level of HDL cholesterol and combined statinotherapy with UDCA in decrease of level of triglycerides. It was confirmed the significant advantages of combined statinotherapy with UDCA as for the influence on functional state of liver and CRP level, and advantages of rosuvastatin of 10 mg in combination with UDCA. Thus, the combination of rosuvastatin of 10 mg with UDCA should be preferable in the treatment of patients with myocardial infarction in combination with non-alcoholic steatohepatitis from the positions of the effectiveness and safety. Besides, taking into account positive correlation between the CRP level in blood and activity of transaminases in the dynamics of observation it can be concluded that high activity of transaminases is the prognostic marker of the severity and procession of polymorbid pathology - myocardial infarction in combination with non-alcoholic steatohepatitis.

Henoch-Schönlein purpura (HSP) is a systemic vasculitis affecting small vessels. It is the most common systemic vasculitis in children, and is rare in adults. Serious gastrointestinal complications are more common in childhood. Infections and drugs are the most prominent factors in the aetiology. Wall thickening in segments of the small intestine is commonly seen in imaging studies in gastrointestinal system (GIS) involvement. Simultaneous involvement of small intestine and colon is rare. An HSP case involving small intestine and colon in an adult patient due to the use of rosuvastatin, an antihyperlipidaemic agent, is presented, and is first of its kind reported in the literature.

Background: Statin-related myalgia is difficult to distinguish from other conditions causing myalgia and may often lead to statin discontinuation., Objective: To compare the effect of statin rechallenge with placebo in patients with prior statin-related myalgia and to determine whether patients resumed statin therapy after evaluating the results., Design: N-of-1 trial with 3 double-blind, crossover comparisons separated by 3-week washout periods. (Clinicaltrials.gov: NCT01259791) SETTING: Tertiary care lipid clinic., Patients: Patients with prior statin-related myalgia with or without mild elevation of creatine kinase levels., Intervention: Rechallenge with the statin that was previously associated with myalgia within 3 weeks of open-label use versus matching placebo., Measurements: Weekly visual analogue scale (VAS) scores for myalgia and specific symptoms (VAS myalgia score and symptom-specific VAS score, respectively), pain interference scores, and pain severity scores were recorded during the 3-week periods when patients were receiving placebo or statin. The primary outcome was the VAS myalgia score (range, 0 to 100 mm)., Results: Eight patients (mean age, 66 years [SD, 8 years]; 88% women, all with high 10-year Framingham cardiovascular risk) participated in n-of-1 trials. Seven patients completed 3 treatment pairs, and 1 completed 2 treatment pairs. For each n-of-1 trial, no statistically significant differences were seen between statin and placebo in the VAS myalgia score, symptom-specific VAS score, pain interference score, and pain severity score. Five patients resumed open-label statin treatment, with a median posttrial follow-up of 10 months., Limitation: Results are limited by the small sample size and cannot be extended to patients with longer onset of myalgia after statin initiation., Conclusion: In selected patients with a history of statin-related myalgia whose symptoms are difficult to evaluate, n-of-1 trials may be a useful method for determining statin tolerability., Primary Funding Source: Western University, London, Ontario, Canada.

Rosuvastatin is a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor (statin) that reduces low-density lipoprotein cholesterol levels to the greatest extent of all currently marketed statins. Prospective, randomized studies demonstrate the ability of rosuvastatin to reduce the risk of cardiovascular events and stabilize atherosclerosis. However, the efficacy of rosuvastatin in patient subpopulations (eg, patients with chronic kidney disease, women, ethnic subgroups) is not well described in the literature. To provide an updated, comprehensive review of the efficacy and safety of rosuvastatin, a literature search of PubMed was conducted using statins as a major topic, MESH topic, or a word in the title (including rosuvastatin, fluvastatin, atorvastatin, pitavastatin, lovastatin, pravastatin, and simvastatin). Publications selected for inclusion in this review were published from January 1, 2010 to December 31, 2013, and provide new information pertaining to the efficacy and safety of rosuvastatin.

Objectives: The goal of this clinical trial was to determine the incidence of undesirable side effects, and to ascertain any occurrence of genetic polymorphisms., Material and Methods: Clinically, we looked for manifestations of a benign myositis and of serious rhabdomyolysis. We observed a group 198 patients treated with statins, primarially fluvastatin and rosuvastatin. There were 126 (mean age = 58.3 ± 4.1; male 91, mean age = 57.4 ± 5.9; female 35, mean age = 60.5 ± 6.5) patients in a subgroup where we administered rosuvastatin. Undesirable muscular signs and symptoms were present in 32 patients (25.39%). In 11 (8.73% of the total 126) CK level increased maximally to 4 times ULN, in 6 (4.7%) statins were excluded because of very intense subjective suffering. CK levels 2-5 times ULN were present in 9 (7.14%). CK blood levels over 10 times ULN or higher indicated statins exclusion in 2 (1.58%). Increased levels of the further muscular enzyme AST by 5 times ULN were present in 16 (12.69%), up to 10 times ULN in 2 (1.58%), and over 10 times ULN also in 2 (1.58%)., Results: We observed rhabdomyolysis in 6 patients (3.03% of the total 198 patients group) using other types of statins (three of them undergo chronic hemodialysis). In this group we performed molecular-genetic analysis of the following proteins relating to statin myopathy: SLCO1B1(388AA/AG-521TT) - (discovered polymorphism in 1 patient), further cytochroms Cyp 2C9 (in 1 patient), 2C8 (in 1 patient), Cyp SA/4 (non discovered positivity) and finally UGT1A1*2B (discovered in 2 patients)., Conclusions: In the group of patients treated by rosuvastatin, we discovered not one case of rhabdomyolysis. In each patient with rhabdomyolysis (brown urine discoloration, mal-odorous urine, painful muscle cramps, muscle weakness, fatigue) at least one polymorphism of "statins´ genes" was present.

Background: Previous studies have demonstrated that intensive lipid lowering using rosuvastatin results in regression of coronary plaques. However, few data exist regarding lipid profiles over time, drug tolerability, and the effects of prior use of lipid lowering agents in patients on rosuvastatin treatment. Therefore, we studied these matters in a subanalysis of the Coronary Atherosclerosis Study Measuring Effects of Rosuvastatin Using Intravascular Ultrasound in Japanese Subjects (COSMOS)., Methods: Rosuvastatin was titrated for 76 weeks to attain LDL-C < 80 mg/dL in 213 Japanese dyslipidemic patients with CAD. Clinic visits were scheduled for every 4 weeks during the 76-week study period. Changes over time in lipid parameters, changes in those according to prior lipid-lowering therapy, and changes in those according to baseline lipid levels were evaluated in this subanalysis., Results: Overall, 126 patients completed the study. The mean rosuvastatin dose at the last observation carried forward was 16.9 mg (range, 2.5-20 mg). Rosuvastatin significantly increased HDL-C, lowered LDL-C, and improved the LDL-C/HDL-C ratio (all, P < 0.0001). Increases in serum HDL-C levels were significantly greater in patients with HDL-C < 40 mg/dL than in those with HDL-C ≥ 40 mg/dL at baseline (P = 0.0005). The estimated glomerular filtration rate increased significantly by 2.84 ± 9.01 mL/min/1.73 m(2) (P < 0.0001). Of 166 adverse events in 74 patients, 113 events in 54 patients were laboratory values beyond the normal range., Conclusion: Rosuvastatin significantly improved lipid profiles, with an acceptable safety profile, contributing to plaque regression in Japanese patients with CAD., (© 2013 John Wiley & Sons Ltd.)

Backgrounds and Aims: To assess the burden of statin related muscular symptom in real life., Methods and Results: We conducted a wide survey on 10,409 French subjects. Among these, 2850 (27%) had hypercholesterolemia and 1074 were treated with statins. Muscular symptoms were reported by 104 (10%) statin treated patients and led to discontinuation in 30% of the symptomatic patients. The main prescribed statins were low doses rosuvastatin, atorvastatin and simvastatin. Pains were the most commonly described symptoms (87%) but many patients also reported stiffness (62%), cramps (67%), weakness or a loss of strength during exertion (55%). Pain was localized in 70% but mostly described as affecting several muscular groups. Approximately 38% of patients reported that their symptoms prevented even moderate exertion during everyday activities, while 42% of patients suffered major disruption to their everyday life., Conclusion: Muscular symptoms associated with average dosage statin therapy are more frequent than in clinical trials and have a greater impact on patients' life than usually thought., (Copyright © 2012 Elsevier B.V.

Background: Statin therapy is recommended for children with familial hypercholesterolemia (FH), but most children do not reach treatment targets., Objective: Here we present the design and results at baseline of the ongoing CHARON study, to evaluate the safety and efficacy of rosuvastatin., Methods: This study comprises an international 2-year open label, titration-to-goal study in 198 children with heterozygous FH aged 6 to 18 years, with rosuvastatin in a maximum dose of 10 mg (<10 years of age) or 20 mg (older children). In addition, 64 unaffected siblings were enrolled as controls. The primary efficacy outcome is the change from baseline in low-density lipoprotein cholesterol, and the secondary outcome is the change in carotid intima-media thickness (c-IMT) in patients with FH compared with their siblings. The primary safety outcomes are growth and sexual maturation; secondary outcomes are the change in other lipoprotein levels and the incidence of adverse events, discontinuation rates, and abnormal laboratory values., Results: At baseline, mean age of patients with FH was 12.1 ± 3.3 years, 44% were boys, and mean low-density lipoprotein cholesterol levels were 6.1 ± 1.3 mmol/L (235.9 ± 48.7 mg/dL). Mean c-IMT was 0.399 mm (95% CI, 0.392-0.406 mm) in children with FH versus 0.377 (95% CI, 0.366-0.388 mm) in unaffected siblings (P = .001)., Conclusions: At baseline, as expected according to on previous observations, children with FH proved to have a greater c-IMT than their healthy siblings. These differences had already occurred at a very young age, which emphasizes the importance of considering early statin initiation in this high-risk population., (Copyright © 2013 National Lipid Association.

Background: Patients with chronic kidney disease (CKD) often have mixed dyslipidemia and high cardiovascular disease risk. Although statins reduce LDL-C, adding a fibrate may further improve lipid parameters., Objective: This multicenter, randomized study evaluated the short-term efficacy and safety profile of fenofibric acid (FA) + rosuvastatin (R) combination therapy for improving lipid parameters in patients with stage 3 CKD and mixed dyslipidemia. The study also assessed estimated glomerular filtration rate after study drug washout., Methods: Patients received FA 45 mg + R (5 mg for 8 weeks, then 10 mg for 8 additional weeks) or R monotherapy (5 mg for 8 weeks, then 10 mg for 8 additional weeks), followed by an 8-week washout period. Primary and secondary end points were percent changes in triglycerides and HDL-C, respectively, from baseline to week 8., Results: FA 45 mg + R 5 mg, compared with R 5 mg, resulted in significant improvements in triglycerides (median % changes: week 8, -38.0% vs -22.4%, P < 0.001; week 16, -42.6% vs -29.7%, P < 0.001) and HDL-C (mean % changes: week 8, 16.9% vs 7.8%, P < 0.001; week 16, 17.3% vs 8.9%, P < 0.001). Adverse event rates were similar between groups (70.7% with FA + R vs 68.6% with R). Mean serum creatinine level at baseline was 1.36 mg/dL in the FA + R group and 1.38 mg/dL in the R group. The final treatment serum creatinine value, defined as the last nonmissing postbaseline value collected within 30 days after the last dose of study drug, was 1.52 mg/dL with FA + R (vs 1.41 mg/dL with R; P < 0.001), which then decreased to 1.39 mg/dL after the 8-week washout (vs 1.42 mg/dL with R)., Conclusions: The data suggest that, after 16 weeks of therapy, FA + R has an acceptable safety profile and improved TG and HDL-C efficacy versus R. FA + R combination therapy may thus further improve lipid parameters in patients with stage 3 CKD and mixed dyslipidemia.

Background: Rosuvastatin, a lipid-lowering agent, has been widely used with olmesartan, a long-acting angiotensin II receptor blocker, indicated for the treatment of dyslipidemia accompanied by hypertension. A fixed-dose combination (FDC) tablet of these 2 drugs was recently developed to enhance the dosing convenience and to increase patient compliance while yielding pharmacokinetic profiles comparable to coadministration of each drug as individual tablets., Objective: The goal of present study was to compare the pharmacokinetic profiles of single-dose administration of an FDC tablet containing rosuvastatin/olmesartan 20/40 mg (test formulation) with coadministration of a rosuvastatin 20-mg tablet and a olmesartan 40-mg tablet (reference formulation) in healthy Korean male volunteers, for the purpose of determining bioequivalence., Methods: This single-dose, randomized, open-label, 2-period crossover study enrolled subjects aged 20 to 50 years and within 20% of ideal body weight. Each subject received a single dose of the test and reference formulations orally in a fasted state, with a 7-day washout period between the administrations. Blood samples were collected up to 72 hours after dosing, and pharmacokinetic parameters were determined for rosuvastatin, its active metabolite (N-desmethyl rosuvastatin), and olmesartan. Bioequivalence was concluded if the 90% CIs of the geometric mean ratios for the primary pharmacokinetic parameters were within the predetermined range of 80% to 125%. Adverse events (AEs) were evaluated based on subject interviews and physical examinations., Results: Among the 58 enrolled subjects, 54 completed the study. The 90% CIs of the geometric mean ratios of the primary pharmacokinetic parameters were as follows: rosuvastatin: AUC(last), 85.60% to 97.40% and C(max), 83.16% to 98.21%; N-desmethyl rosuvastatin: AUC(last), 82.08% to 93.45% and C(max), 79.23% to 93.41%; and olmesartan: AUC(last), 97.69% to 105.69% and C(max), 100.35% to 109.42%. The most frequently noted AE was headache, occurring in 3 and 6 patients with the test and reference formulations, respectively. All of the AEs were expected, and there was no significant difference in the prevalences of AEs between the 2 formulations., Conclusions: The pharmacokinetic properties of the newly developed FDC tablet of rosuvastatin/olmesartan 20/40 mg suggest that it is bioequivalent to co-administration of each drug as individual tablets in these healthy Korean male subjects. The two formulations were well tolerated, with no serious AEs observed. ClinicalTrials.gov identifier: NCT01823900., (Copyright © 2013 Elsevier HS Journals, Inc. All rights reserved.)

Background: Statins can cause tubular proteinuria by inhibiting tubular reabsorption of urinary proteins. To distinguish between microalbuminuria originating from glomerular leakage of albumin and tubular microalbuminuria due to statin therapy, the α1-microglobulin/albumin ratio is evaluated in patients taking statins and compared to untreated patients., Methods: Ten apparently healthy subjects were given 40 mg of simvastatin and tested for urinary α1-microglobulin, albumin, creatinine and cystatin C, up to 24 h after administration. Additionally, urine samples of 76 statin-treated and 456 untreated patients presenting with micro-albuminuria (albuminuria range between 20 and 200 mg/L) were tested for α1-microglobulin and albumin. α1-Microglobulin/albumin ratios were compared. Total cholesterol was measured in 50 patients on statin therapy., Results: In the 10 apparently healthy subjects, a significant temporary increase of α1-microglobulin, albumin and α1-microglobulin/albumin ratio was observed after statin intake. In the group of 532 patients showing micro-albuminuria, those treated with statins showed a significantly higher mean urinary α1-microglobulin/albumin ratio then untreated patients. Urinary albumin concentrations were significantly higher in patients taking simvastatin than in patients on rosuvastatin treatment and they were also higher in patients on statin therapy with a total serum cholesterol concentration below 3.88 mmol/L than in patients with a total serum cholesterol concentration above 5.17 mmol/L., Conclusions: Tubular proteinuria, caused by the use of statins, can be distinguished from glomerular proteinuria by a higher urinary α1-microglobulin/albumin ratio.

1. This work investigated the drug interaction potential of GSK1292263, a novel GPR119 agonist, with the HMG-coA reductase inhibitors simvastatin and rosuvastatin. 2. In vitro experiments assessed the inhibition of transporters and CYP enzymes by GSK1292263, and a clinical drug interaction study investigated the effect of GSK1292263 (300 mg BID) on the pharmacokinetic profile of simvastatin (40 mg single dose) and rosuvastatin (10 mg single dose). 3. In vitro, GSK1292263 demonstrated little/weak inhibition (IC50 values >30 μM) towards CYPs (CYP1A2, 2C9, 2C19, 2D6, 3A4), Pgp, OATP1B3, or OCT2. However, GSK1292263 inhibited BCRP and OATP1B1, which are transporters involved in statin disposition. 4. In the clinical study, small increases in the AUC(0-inf) of simvastatin [mean ratio (90% CI) of 1.34 (1.22, 1.48)] and rosuvastatin [mean ratio (90% CI) of 1.39 (1.30, 1.49)] were observed when co-administered with GSK1292263, which is consistent with an inhibitory effect on intestinal BCRP and CYP3A4. In contrast, GSK1292263 did not inhibit OATP1B1 based on the lack of changes in simvastatin acid exposure [mean AUC(0-inf) ratio (90% CI) of 1.05 (0.91, 1.21)]. 5. GSK1292263 has a weak drug interaction with simvastatin and rosuvastain. This study provides a mechanistic understanding of the in vivo inhibition of transporters and enzymes by GSK1292263.

Background: Statin use has been associated with adverse effects on insulin sensitivity and the development of new-onset diabetes. Colesevelam exhibits favorable effects on glucose metabolism. It is not known whether the combination of colesevelam plus low-dose statin has different effects on insulin resistance versus higher-dose statin in patients with impaired fasting glucose (IFG) and hypercholesterolemia., Methods: This was a prospective randomized open-label blinded end point (PROBE) study. Forty patients with hypercholesterolemia and IFG were randomized to receive rosuvastatin 5 mg/day plus colesevelam 3.75 g/day (RC, n=20) or rosuvastatin 10 mg (R, n=20) for 3 months. The primary end point was the difference in the change of homeostasis model assessment of insulin resistance (HOMA-IR) index between the groups., Results: HOMA-IR index significantly decreased in the RC group (-32%, P=0.04 vs. baseline) but nonsignificantly increased (+15%, P=NS) in the R group. Insulin levels decreased in the RC group (-26%, P=NS) but increased in the R group (+15%, P=NS). Both changes in HOMA-IR and insulin differed significantly between groups (both p<0.05). Glucose levels decreased in the RC group (-5%, P=NS), whereas they remained unaltered in the R group. Similar reductions in low-density lipoprotein cholesterol were observed in both groups (-45%; P<0.001 vs. baseline). Triglycerides remained unchanged in the RC group but decreased in the R group (-24%, P<0.001 vs. baseline and P=0.02 vs. RC group)., Conclusions: The combination of colesevelam with rosuvastatin 5 mg/day may be associated with favorable effects on markers of insulin resistance compared with rosuvastatin 10 mg/day in patients with hypercholesterolemia and IFG. Whether this is associated with less new-onset diabetes remains unknown.

Introduction: Low-density lipoprotein cholesterol (LDL-C) reduction using 3-hydroxy-3-methyl glutaryl coenzyme A (HMGCoA) reductase inhibitors (statins) has a proven survival benefit in patients presenting with acute coronary syndromes (ACS). Patients presenting with ACS remain at significant risk of subsequent cardiovascular death and non-fatal myocardial infarction despite high compliance with current guideline indicated secondary prevention therapies. There remains, therefore, a need to consider the potential benefits of more intensive LDL-C lowering after presentation with ACS. Rosuvastatin is the most potent of the currently available statins and has some unique pharmacological properties that may be advantageous in such patients., Areas Covered: We conducted a Medline literature search to identify rosuvastatin papers and papers on statin use in ACS published in English. In this review, we outline the pharmacology of rosuvastatin and examine its efficacy and safety. We also evaluate the published trials of statin therapy in ACS and offer an opinion on the use of rosuvastatin in ACS., Expert Opinion: There is adequate clinical trial evidence confirming the LDL-C lowering efficacy and safety of high-dose rosuvastatin in ACS. Whilst there are sound theoretical reasons to consider early use of high-dose rosuvastatin in ACS, the available level of evidence is insufficient to justify a wholesale change from the current standard of care.

Background: Carriers of the rs4363657C and rs4149056C alleles in SLCO1B1 have increased myopathic complaints when taking simvastatin. Whether rosuvastatin has a similar effect is uncertain. This study assesses whether SLCO1B1 polymorphisms relate to clinical myalgia after rosuvastatin therapy., Methods: In the JUPITER trial, participants without prior cardiovascular disease or diabetes who had low-density lipoprotein cholesterol <130 mg/dL and C-reactive protein ≥2 mg/L were randomly allocated to rosuvastatin 20 mg or placebo and followed for the first cardiovascular disease events and adverse effects. We evaluated the effect of rs4363657 and rs4149056 in SLCO1B1, which encodes organic anion-transporting polypeptide OATP1B1, a regulator of hepatic statin uptake, on clinically reported myalgia., Results: Among 4,404 participants allocated to rosuvastatin, clinical myalgia occurred with a rate of 4.1 events per 100 person-years as compared with 3.7 events per 100 person-years among 4,378 participants allocated to placebo (hazard ratio [HR] 1.13, 95% CI 0.98-1.30). Among those on rosuvastatin, there were no differences in the rate of myalgia among those with the rs4363657C (HR 0.95, 95% CI 0.79-1.14 per allele) or the rs4149056C allele (HR 0.95, 95% CI 0.79-1.15 per allele) compared with those without the C allele. Similar null data were observed when the myalgia definition was broadened to include muscle weakness, stiffness, or pain. None of the 3 participants on rosuvastatin or the 3 participants on placebo with frank myopathy had the minor allele at either polymorphism., Conclusion: There appears to be no increased risk of myalgia among users of rosuvastatin who carry the rs4363657C or the rs4149056C allele in SLCO1B1., (Copyright © 2013 Mosby, Inc.

Objective: To examine the risk of new onset diabetes among patients treated with different HMG-CoA reductase inhibitors (statins)., Design: Population based cohort study with time to event analyses to estimate the relation between use of particular statins and incident diabetes. Hazard ratios were calculated to determine the effect of dose and type of statin on the risk of incident diabetes., Setting: Ontario, Canada., Participants: All patients aged 66 or older without diabetes who started treatment with statins from 1 August 1997 to 31 March 2010. The analysis was restricted to new users who had not been prescribed a statin in at least the preceding year. Patients with established diabetes before the start of treatment were excluded., Interventions: Treatment with statins., Main Outcome Measure: Incident diabetes., Results: Compared with pravastatin (the reference drug in all analyses), there was an increased risk of incident diabetes with atorvastatin (adjusted hazard ratio 1.22, 95% confidence interval 1.15 to 1.29), rosuvastatin (1.18, 1.10 to 1.26), and simvastatin (1.10, 1.04 to 1.17). There was no significantly increased risk among people who received fluvastatin (0.95, 0.81 to 1.11) or lovastatin (0.99, 0.86 to 1.14). The absolute risk for incident diabetes was about 31 and 34 events per 1000 person years for atorvastatin and rosuvastatin, respectively. There was a slightly higher [corrected] absolute risk with simvastatin (26 outcomes per 1000 person years) compared with pravastatin (23 outcomes per 1000 person years). Our findings were consistent regardless of whether statins were used for primary or secondary prevention of cardiovascular disease. Although similar results were observed when statins were grouped by potency, the risk of incident diabetes associated with use of rosuvastatin became non-significant (adjusted hazard ratio 1.01, 0.94 to 1.09) when dose was taken into account., Conclusions: Compared with pravastatin, treatment with higher potency statins, especially atorvastatin and simvastatin, might be associated with an increased risk of new onset diabetes.

The low-density lipoprotein cholesterol (LDL-C) lowering efficacy of switching to ezetimibe/simvastatin (EZ/S) 10/20 mg versus doubling the run-in statin dose (to simvastatin 40 mg or atorvastatin 20 mg) or switching to rosuvastatin 10 mg in subjects with cardiovascular disease (CVD) and diabetes was assessed. Endpoints included percentage change in LDL-C and percentage of patients achieving LDL-C <70 mg/dL. Significantly greater reductions in LDL-C occurred when switching to EZ/S versus statin doubling in the overall population and in subjects treated with simvastatin 20 mg or atorvastatin 10 mg (all p < 0.001). The LDL-C reduction was numerically greater when switching to EZ/S versus switching to rosuvastatin (p = 0.060). Significantly more subjects reached LDL-C <70 mg/dL with EZ/S (54.5%) versus statin doubling (27.0%) or rosuvastatin (42.5%) in the overall population (all p < 0.001) and within each stratum (all p < 0.001). Switching to EZ/S provided significantly greater reductions in LDL-C versus statin doubling and significantly greater achievement of LDL-C targets versus statin doubling or switching to rosuvastatin.
