This research aimed to examine the effects of pre-treatment with basil extract, prepared as an infusion, on acetaminophen-induced acute liver injury in rats. In vitro analysis of total phenolic, flavonoid content, and antioxidant activity was performed by spectrophotometric methods. Effects of basil extract on oxidative stress parameters, biochemical markers of liver injury, and liver morphology were determined in an in vivo model of acetaminophen-induced liver injury in Wistar rats. Total phenolic content was 52.61 ± 1.35 mg GAE/g of DE, and flavonoid content was 0.5 ± 0.2 mg QE/g of DE. IC50 values ranged from 0.22 to 45.76 μg/ml for DPPH radical, OH radical, H2O2 and lipid peroxidation. Ascorbic acid was used as a positive control. The extract lowered the intensity of lipid peroxidation and potentiated the activity of antioxidant enzymes. In addition, serum levels of aspartate aminotransferase and alanine aminotransferase were significantly lower in basil extract-treated animals in comparison to respective controls.

The beneficial medical properties of cannabis in treatment of variety of diseases have been widely recognized across many cultures (Zuardi, 2006, Aggarwal et al., 2009, Birdsall et al., 2016). At the end of the 19th century in Europe, cannabis was considered effective for the treatment of chronic pain, asthma, sleep disorders, depression, and loss of appetite (Guy et al., 2004, Manzanares et al., 2006, Sabo et al., 2013). Medical use of cannabis continued until the first half of the 20th century, when legal restrictions were introduced due to the psychoactive constituent - delta-9-tetrahydrocannabinol (THC), which is one of at least 113 cannabinoids identified in cannabis (Ben Amar, 2006, Horvat et al., 2007). In Serbia, cannabis is classified under narcotic drugs, and the production, sale and possession of cannabis for recreational use or any form of medical marijuana products is illegal (Law on Psychoactive Controlled Substances). Recently, a number of countries in Europe have introduced specific laws and programs to allow patients to use cannabis preparations to effectively relieve the symptoms of chronic pain, muscle cramps and spasticity in patients with multiple sclerosis, to alleviate nausea and vomiting and to improve weight gain and appetite in patients with AIDS (European Monitoring Centre for Drugs and Drug Addiction, 2017). Besides Netherlands, a country with more than 10 years of experience in medical cannabis use, medical cannabis has also been legalized in Italy, Spain, France, Romania and Czech Republic. As for the countries surrounding Serbia, Croatia and Macedonia are the most recent countries which have allowed the use of cannabis in medical purposes (Bifulco and Pisanti, 2015). As more countries in Europe and worldwide continue to change laws for medical marijuana use, public interest in medical cannabis legalization in Serbia is growing. When medical cannabis is legalized in Serbia, doctors will be the ones who will prescribe the products and answer to patients’ questions about its use, benefits and side effects. It is of immense importance to bear in mind specific harmful effects of cannabis, especially in young people. Cannabis is indicated as a possible risk factor for cardiovascular disease in young adults due to increased reporting of cardiovascular complications related to cannabis and their extreme seriousness (Jouanjus et al., 2014). Furthermore, exposure to cannabis during adolescence has been connected to deviations in the normal neurodevelopment, producing a brain particularly at risk of psychiatric disorders such as schizophrenia (Iannitelli et al., 2017, Quartini et al., 2017). Yet, prospective doctors may receive minimal education on this issue throughout the curriculum. A paucity of studies exist evaluating future health care professionals’ knowledge and attitude towards medical cannabis (Sabo et al., 2013, Ben Amar, 2006). In Serbia, one study evaluated beliefs about medical cannabis among fourth-year medical students, while another included only the final year students of pharmacy (Vujcic et al., 2017, Stojanovic et al., 2017). The aim of this study was to determine the frequency of recreational cannabis use among medical students and to explore their knowledge about therapeutic use/abuse, side effects and current legislation status of medical cannabis, as well as attitudes toward its legalization.

A surveillance study was performed in an intensive care unit in the largest tertiary health care center in Vojvodina, Serbia from 2014 to 2018. Antibiotic prescription data were collated in the WHO anatomical therapeutic chemical (ATC)/defined daily dose (DDD) format, while antibiotic resistance was expressed as incidence density adjusted for total inpatient-days. Individual trends were determined by linear regression, while possible associations between antibiotic prescription and resistance were evaluated using cross-correlation analysis. An overall decrease in antibiotic utilization was observed. The prescription rates of piperacillin-tazobactam increased significantly, while consumption of 3rd and 4th generation cephalosporins and fluoroquinolones decreased. There were rising incidence densities of doripenem resistant Acinetobacter spp., piperacillin-tazobactam resistant Pseudomonas aeruginosa and carbapenem and colistin resistant Klebsiella pneumoniae. These results can serve as a basis for the development of antimicrobial stewardship strategies in the current setting.

The plant world represents an important source of potential therapeutic agents, but concomitant administration of herbal and conventional medications may result in interactions with subsequent beneficial or adverse effects. This study was designed to examine the analgesic effect of thyme tincture and thyme syrup, two commonly used thyme formulations, and their interactions with codeine, paracetamol, pentobarbital and diazepam in mice. The identification and quantification of thymol and carvacrol were carried out by GC/MS and GC/FID. The analgesic activity was studied using a hot plate method. Effects of thyme syrup on diazepam-induced motor coordination impairment in rotarod test and on pentobarbital-induced sleeping time were also determined. Thymol (175.3 µg/mL and 9.73 µg/mL) and carvacrol (10.54 µg/mL and 0.55 µg/mL) concentrations were measured in tincture and syrup, respectively. Thyme syrup and tincture exhibited effective analgesic activity in the hot plate pain model. Pretreatment with thyme formulations reduced analgesic activity of codeine, and potentiated the analgesic activity of paracetamol. Co-administration of thyme formulations has led to potentiation of diazepam and pentobarbital depressive central nervous system effects. Thyme formulations interacted with tested conventional drugs, probably through interference with their metabolic pathways and succeeding altered concentrations and pharmacological effects.

This study investigated the chemical and nutritional profile and antioxidative properties of cultivated Coprinus comatus . Proximate analysis revealed that C. comatus is rich in carbohydrates, dietary fibres and proteins, and could also be a valuable source of phenolics. Additionally, fat content is low, consisting mainly of polyunsaturated and omega-3 fatty acids. Furthermore, the safety profile of C. comatus is satisfactory, with all elements of toxicological importance within the proposed limits. Oral treatment with C. comatus for 42 days improved the antioxidant capabilities and ameliorated carbon tetrachloride-induced liver damage in rats, marked by decreased serum aminotransferase levels and lipid peroxidation intensity. Glutathione concentrations increased in a dose-dependent manner. Histological morphometric and immunohistochemical analysis confirmed antioxidative and hepatoprotective potential. These findings imply that cultivated C. comatus could be considered a nutraceutical, having beneficial nutrient and therapeutic properties.

Background/Aim. Hypertension is one of the leading causes of cardiovascular morbidity and mortality and more than a half of all health insurance expenditures for reimbursed medicines are allocated to antihypertensive drugs in Serbia. The aim of this study was to identify the antihypertensive drug utilization patterns among hypertensive outpatients in the city of Novi Sad, Serbia, determine the adherence to clinical guidelines and address the economic aspects of current prescribing practices. Methods. This retrospective observational study was conducted in Novi Sad over a period of six months. The data on the number of packages, size of packages, and retail price of antihypertensives issued on prescription in outpatients with the diagnosis of essential arterial hypertension was collected from all state-owned pharmacies in Novi Sad. Drug consumption was analyzed using the Anatomical Therapeutic Chemical (ATC)/defined daily dose (DDD) methodology. Results. Total consumption of antihypertensives issued on prescription over 6 month period in the city of Novi sad, Serbia was 283,48 DDD per 1,000 inhabitans per day (DID). Angiotensin converting enzyme inhibitors (ACEi) were most commonly prescribed drugs, and were used 3 times more often than calcium channel blockers and 5 times more than betablockers. The consumption of diuretics and angiotensin receptor antagonists was low within all groups of outpatients. Both national and international guidelines state superiority and effectiveness of diuretics in treatment of hypertension in the elderly, but their consumption was unreasonable low despite the fact that over 70% of all antihypertensive drugs in the city of Novi Sad were dispensed in people aged > 60. The use of more expensive ACEi was observed, despite the guidelines deeming all the drugs of these class equally effective in treatment of hypertension. Conclusion. Large differences in utilization of different groups of antihypertensive agents were noted in this study. Underutilization of valuable, efficacious, and cost-effective thiazide diuretics and over use of expensive ACE inhibitors is unjustifiable. There is a potential for large savings with switching to low-price ACEi, modeling the practice of Scandinavian countries. [Projekat Ministarstva nauke Republike Srbije, br. III 41012]

Ciprofloxacin is often used in treatment of complicated urinary tract infections in areas with high rates of resistance to first line agents. The aim of this study was to evaluate efficacy of ciprofloxacin in standard dosing regimens in treatment of complicated urinary tract infections. Plasma concentration curves were simulated and minimum inhibitory concentration (MIC) and post-antibiotic effect were determined. Ciprofloxacin MIC ranged from 0.0156 for Gram-negative and to 0.125-0.5 µg/mL for Gram-positive bacteria. Both dosing regimens were suitable for eradication of Gram-negative bacteria, with slight supremacy of 750 mg/12 hours over 500 mg/12 hours dosing regimen. Even though all strains were fully susceptible to ciprofloxacin, pharmaco-kinetic/pharmacodynamic parameters did not meet target thresholds for pathogens with MIC over 0.1-0.2 µg/mL regardless of the administered dose. Ciprofloxacin remains an excellent choice for treatment of complicated urinary tract infections caused by Gram-negative bacteria, but in infection caused by Gram-positive strains, deeper analysis is necessary in order to achieve optimal results.

Introduction: With the growing trend for legalization of cannabis and its derivatives in Serbia, pharmacists are likely to be consulted on the safety, efficacy, and drug-drug or drug-disease interactions of medical cannabis. Thus, the aim of our study was to assess pharmacy students’ knowledge and attitude toward medical cannabis use in Serbia to determine if additional education is needed. Subjects and methods: In the study students from the final year of the study program of integrated academic studies of pharmacy at the Faculty of Medicine, University of Novi Sad were asked to complete an anonymous questionnaire regarding their knowledge and attitudes on the use of cannabis and its derivatives in medical purposes. After giving their written informed consent, they were instructed by the researchers on how to complete the questionnaire. All questionnaires were administered between August 1, 2017 and August 15, 2017. The study was approved by the Ethical Committee of the Faculty of Medicine in Novi Sad; a total of 80 questionnaires were distributed. The questionnaire consisted of 3 groups of statements on which they should mark level of their agreement related to students’ knowledge about the use of cannabis and its derivatives in therapeutical purposes, potential negative effects, dispensing in a pharmacy and legalization of cannabis and its derivatives in medical purposes. Results: Although 91.2% of the respondents agreed that cannabis and its derivatives could potentially have therapeutical effects, much lower percentage of respondents (51.3%) were familiar with possible therapeutical effects of cannabis. The same percentage of respondents learned about therapeutical effects of cannabis from sources other than school. About third (31.3%) of our respondents thought that the use of cannabis and its derivatives in therapeutical purposes could cause their abuse and the similar percentage of respondents (33.8%) thought that issuing cannabis and its derivatives in the pharmacy could expose a pharmacist to the certain dangers such as insisting on the issuing without the prescription or robbery. About 90% of the respondents agreed it is necessary to create clear guidelines for the use of cannabis and its derivatives in therapeutical purposes and 76.3% of the respondents thought that doctor’s prescription is necessary for their dispensing in a pharmacy. Most of the respondents (75%) agreed that, based on the experiences of the countries which have approved the use of cannabis and its derivatives in therapeutical purposes, its use in those purposes should be approved in Serbia. Conclusion: The majority of pharmacy students supported medical cannabis legalization but only with strict legal regulations and clear guidelines for their use implemented. Further education of the pharmacist about therapeutical effect of cannabis is necessary.
