A simple UV spectrophotometric method for the analysis of Amlodipine Besylate was developed to analyze the drug in bulk and in tablet formulation. In this method the simple UV spectrum of Amlodipine Besylate in aqueous ethanol (30% v/v) was obtained which exhibits absorption maxima (λ max) at 239.40 nm. The Beers law ranges was followed in the concentration range of 5-60 μg/ml. The proposed met...

BACKGROUND It has been shown that administration of lacidipine markedly reduces systolic blood pressure in elderly patients with hypertension without increasing the incidence of cardiovascular events and total mortality. But in Korea, there were no available data about the effectiveness and safety of lacidipine. OBJECTIVES The goal of our study was to compare the effect of lacidipine and amlo...

Amlodipine is a long-acting calcium channel blocker used in the treatment of hypertension and angina pectoris. S-(−)-amlodipine besylate is a safer and longer-acting alternative to the existing racemate [1]. Although several products based on the active enantiomer have reached the market, information on its chemical, physical and thermal stability during storage is lacking [2, 3]. The objective...

A simple, precise, rapid and accurate RP-HPLC method has been developed for the simultaneous estimation of Amlodipine besylate and Hydrochlorthiazide in tablet formulations. The chromatographic separation was achieved on a Shimadzu Symmetry C18 column (250 mm x 4.6mm, 5.0 μ particle size) using Methanol: Acetonitrile: 50mM Na2HPO4 pH7.0 (60:20:20v/v/v) with 1% triethylamine. Flow rate was 1ml/m...

An accurate, sensitive, and reproducible high-performance liquid chromatographic method for the quantitation of amlodipine besylate in human plasma has been developed and validated. The drug, internal standard, and major metabolite were eluted from a C(18) hypersil HyPurity column (3 microm, 3.9 mm i.d. x 150 mm) at room temperature with a mobile phase consisting of acetonitrile-potassium dihyd...

A fixed-dose combination of amlodipine and olmesartan is used to treat high blood pressure in patients whose hypertension is not sufficiently controlled with either drug alone. The objective of this study was to evaluate the bioequivalence of two fixed-dose combinations, ie, amlodipine orotate/olmesartan medoxomil 10/40 mg and amlodipine besylate/olmesartan medoxomil 10/40 mg, in healthy subjec...

The bioequivalence of combination tablets containing amlodipine besylate/atorvastatin calcium with coadministered matching doses of amlodipine besylate and atorvastatin calcium tablets was investigated in randomized, 2-way crossover studies in healthy volunteers (N = 126). Subjects received a single dose of the amlodipine/atorvastatin tablet or coadministered matching doses of amlodipine and at...

The present review aims to investigate some of the recently reported analytical methods available for assay ofantihypertensive drugs in various combinations pharmaceutical forms. Several simultaneous RP- HPLC have beenreported determination antihypertensive drugs. familiarizes simultaneousdetermination Amlodipine besylate with other drug formulations which are used combination treatmentprotocols.

Article history: Received on: 08/09/2012 Revised on: 19/09/2012 Accepted on: 24/09/2012 Available online: 28/09/2012 A simple, precise and rapid reverse-phase HPLC method has been developed and subsequently validated for the simultaneous estimation of Amlodipine besylate and Enalapril maleate from their combination drug product. The proposed RP-HPLC method utilizes a Phenomenex C18, 5 μm, 250 m...
