We hypothesized that combination treatment with the mineralocorticoid receptor antagonist eplerenone and the calcium channel blocker amlodipine elicits better renoprotective effects than monotherapy with either drug, via different mechanisms in Dahl salt-sensitive (DS) hypertensive rats. DS rats were fed a high-salt diet (4% NaCl) for 10 wk and were treated with vehicle (n = 12), eplerenone (50...

multi-drug therapy in high blood pressure is appreciated to achieve a normalblood pressure.a simple spectrophotometric method based on principal component analysis has been proposed for simultaneous determination of amlodipine (amd) and metoprolol(met) in pharmacutical preparations. calibration matrix contains 3.402 µgml -1 to 170.130 µgml -1 and from 13.060 µgml -1 to 65.3 µgml -1 amlodipine a...

OBJECTIVE The study was aimed to observe the effect of amlodipine on rat pituitary gonadotropins after amlodipine administration and withdrawal. METHODS It was an experimental study done at Army Medical College, National University of Sciences and Technology, Islamabad, Pakistan from 2009-2010. Sixty adult male rats were divided into groups A and B. Each group was further subdivided into two ...

BACKGROUND The purpose of this study was to determine effects of amlodipine, a dihydropyridine calcium channel blocker, on development of angiotensin II (AngII)-induced vascular pathologies. METHODS AND RESULTS Male LDL receptor -/- mice were infused with vehicle, amlodipine (5 mg/kg/d), AngII (1,000 ng/kg/min), or AngII + amlodipine for 4 weeks through osmotic pumps (n=10/group). Mice were f...

This article studies the compatibility of amlodipine besylate in its solid formulations with various drug excipients. The various factors affecting amlodipine besylate stability were studied using high-performance liquid chromatography (HPLC). It has been found that binary 1:1 mixtures of amlodipine besylate and an excipient are stable at 65 degrees C and 40 degrees C/75% RH. Further investigat...

Amlodipine is a commonly prescribed calcium channel blocker for the treatment of hypertension and ischemic heart disease. The drug is slowly cleared in humans primarily via dehydrogenation of its dihydropyridine moiety to a pyridine derivative (M9). Results from clinical drug-drug interaction studies suggest that CYP3A4/5 mediate metabolism of amlodipine. However, attempts to identify a role of...
