OBJECTIVES This study compared the effects of morning and evening dosing of amlodipine/valsartan combination on 24-h blood pressure (BP) in patients uncontrolled by amlodipine (5 mg). METHODS This was a multicenter study that used a prospective, randomized, open-label, blinded endpoint design. Patients with essential hypertension, who's ambulatory BP was uncontrolled after 4 weeks on amlodipi...

This study compares the effects of a calcium channel blocker (amlodipine) and an angiotensin converting enzyme inhibitor (enalapril) on in vivo insulin sensitivity in patients with essential hypertension. Forty-six patients with mild and moderate hypertension were studied. After a 2-week single-blind placebo phase, they were randomly assigned to double-blind therapy with either amlodipine (2.5 ...

A well-characterized and fully validated ultra-high performance liquid chromatography-electrospray ionization-tandem mass spectrometric (UHPLC-ESI-MS/MS) method was developed to reliably analyze combination of perindopril arginine and amlodipine besylate in bulk and tablet formulations. The chromatographic separation was achieved on a Waters ACQUITY UPLC® BEH C18 column with 1.7 μm particle pac...

BACKGROUND The aim of the study was to evaluate whether the combined treatment of calcium channel blocker, amlodipine and beta-blocker, betaxolol, favorably affects cardiac autonomic nervous activity (CANA) and health-related quality of life (HRQL). METHODS AND RESULTS A total of 65 patients with a poor blood pressure (BP) control with a low dose amlodipine therapy were randomly assigned to t...

Cilnidipine, a dual L-/N-type calcium channel blocker, dilates both efferent and afferent arterioles and is renoprotective. Our multi-center, open-labeled, and randomized trial compared the antiproteinuric effect of cilnidipine with that of amlodipine in hypertensive patients with kidney disease. A group of 339 patients, already receiving renin-angiotensin system inhibitor treatment, were rando...

OBJECTIVES We sought to determine whether reperfusion and the calcium channel blocker amlodipine or the angiotensin-converting enzyme inhibitor enalapril, during healing over six weeks after myocardial infarction (MI), limit structural vascular remodeling in the noninfarct zone (NIZ). BACKGROUND The effect of reperfusion and amlodipine or enalapril on structural vascular remodeling during hea...

The cardioprotective effect of amlodipine, a long-acting dihydropyridine derivative, was studied in 2 experimental models of ischemia and reperfusion. Isolated and blood-perfused feline hearts were made globally ischemic for 60 minutes and then reperfused for 60 minutes. Alterations of left ventricular developed pressure and compliance were monitored in both amlodipine-treated hearts and saline...

Objective To compare 1-year treatment adherence of ramipril + amlodipine and ramipril +hydroclorothiazide fixed-dose combination therapies in patients with hypertension. Methods Data were extracted from the database of the National Health Insurance Fund of Hungary. Treatment adherence was modelled using survival analysis. Results At 2 months after initiation of treatment, 42% of patients using ...

This multicentre, double-blind, double-dummy, randomised trial compared the efficacy and tolerability of nisoldipine extended release (10-40 mg) and amlodipine (2.5-10 mg) in 161 patients. The primary end point was a between-treatment comparison of change from baseline to week 8 in mean office diastolic blood pressure (DBP). The least squares mean reductions in systolic (S)BP/DBP (+/- standard ...

BACKGROUND Leg edema is a common adverse effect of dihydropyridine Calcium Channel Blockers (CCB) that may need dose reduction or drug withdrawal, adversely affecting the antihypertensive efficacy. Leg edema is reported to occur less often with (S)-amlodipine compared to conventional racemic amlodipine. We aimed to find the incidence of leg edema as a primary outcome and antihypertensive effica...
