Objective: The aim was to compare the antiproteinuric effect of aliskiren and ramipril in hypertensive patients with type 2 diabetes and microalbuminuria. Research design and methods: A total of 138 patients were treated with aliskiren 300 mg/day or ramipril 10 mg/day for 12 weeks and checked after 1, 2, 4, 8 and 12 weeks and 2 and 4 weeks after treatment withdrawal. Main outcome measures: Clinic and ambulatory BP, urinary albumin excretion rate (UAER) and plasma aldosterone were measured. Results: Both aliskiren and ramipril induced a similar lowering in clinic and ambulatory BP (p < 0.001 vs baseline). However, such a lowering persisted longer after stopping aliskiren than after stopping ramipril regimen. Both treatments reduced UAER, but the decrease in UAER associated with aliskiren was more pronounced, the difference vs ramipril being maximal at week 12 (−42 vs −15%, p < 0.01). Two weeks after stopping therapy, UAER remained below baseline values with aliskiren, but not in the ramipril group. Plasma ...

Objective: The objective of this study was to compare valsartan or ramipril addition to amlodipine + hydrochlorothiazide (HCTZ) on blood pressure (BP) and left ventricular hypertrophy (LVH) in hypertensive diabetic patients with LVH. Research design and methods: 293 patients were treated with amlodipine 10 mg + HCTZ 12.5 combination and then randomized to receive valsartan 160 mg or ramipril 5 mg, in addition to the previous therapy, for 1 year. Main outcome measures: Clinic BP was measured every month; echocardiographic assessments were performed at the end of the placebo period, both before the randomization and after 1-year of triple combination therapy. Results: Both triple regimens similarly reduced SBP/DBP values (-13.5/10.9 mm Hg in the valsartan group and -13.4/10.4 mm Hg in the ramipril group). Triple combination including valsartan better reduced LVMI (-20.1%, p < 0.001), interventricular septal thickness (IVST) (-20.3%, p < 0.001) and left ventricular posterior wall thickness (PWT) (-16.3%, p

Objective: The objective of this study was to assess the effects of valsartan or olmesartan addition to dual therapy with amlodipine + hydrochlorothiazide (HCTZ) in the treatment of stage 2 hypertension. Research design and methods: 180 patients with diastolic blood pressure (DBP) ≥ 99 and < 110 mm Hg were treated with amlodipine 5 mg + HCTZ 12.5 mg combination. After 4 weeks, 149 patients whose blood pressure (BP) was not controlled, were randomized to the combination of valsartan 160 mg + amlodipine 5 mg + HCTZ 12.5 mg or olmesartan 20 mg + amlodipine 5 mg + HCTZ 12.5 mg for 4 weeks. Main outcome measures: At the end of each period, clinical and ambulatory BP measurements were recorded. Results: Both triple combinations produced greater ambulatory and clinical SBP/DBP reduction than dual therapy. However, mean reduction from baseline in the valsartan + amlodipine + HCTZ-treated patients was significantly greater than in the olmesartan + amlodipine + HCTZ-treated patients. Compared with dual therapy, the...
