The effects of losartan potassium, an angiotensin AT(1) receptor blocker on immobility in forced swim test have been studied. Effect of losartan potassium, nortriptyline HCl, fluoxetine HCl and reserpine per se and in combination on forced swimming-induced immobility in mice have also been studied. In mice, losartan potassium elicits biphasic responses i.e. positive responses at lower doses (0....

losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...

losartan potassium, valsartan , telmisartan and irbesartan are angiotensin-ii-receptor antagonists (ara ii) group which used in treatment of hypertension alone or in combination with other drugs mainly hydrochlorothiazide. rp- hplc method was developed for the assay of three angiotensin-ii-receptor antagonists (ara-iis) in presence of hydrochlorothiazide. the method was performed by reversed ph...

The present work describes a validated reverse phase high performance liquid chromatographic method for simultaneous estimation of losartan potassium and Perindopril Erbumine in tablet formulation. Chromatography was performed on a ODS Hypersil C18 (250 mm x 4.6 mm i.d., 5 μm particle size) column with mobile phase containing Acetonitrile: Acidic Water pH 3.4 (50+50). The flow rate was 1.5 mL/m...

A simple, specific and accurate reverse phase liquid chromatographic method was developed for the simultaneous determination of losartan potassium and ramipril in table dosage forms. A hypersil ODS C18, 4.6x250 mm, 5 mum column in isocratic mode, with mobile phase acetonitrile:methanol:10 mM tetra butyl ammonium hydrogen sulphate in water in the ratio of 30:30:40% v/v/v was used. The flow rate ...

background: previous study by the authors showed that a-tocopherol prevents oxidative stress but would not improve depressed excretory variables in post-obstructed kidney (pok) after release of 24-h unilateral ureteral obstruction (uuo). this study is a supplementary investigation on the effects of a-tocopherol combined with an antagonist of angiotensin-ii type-1 (at1) receptor on renal dysfunc...

BACKGROUND A fixed-dose combination (FDC) of amlodipine and losartan has been used to reduce blood pressure in patients whose hypertension is not sufficiently controlled with either drug alone. The aim of this study was to evaluate the pharmacokinetic (PK) characteristics and tolerability of an FDC of 6.94 mg amlodipine besylate (5 mg as amlodipine)/50 mg losartan potassium compared to an FDC o...

The effect of acute oral treatment of losartan potassium, an angiotensin AT1 receptor blocker, on immobility in the forced swim test have been studied using rifampicin-treated (cytochrome P-450 enzyme-induced) and fluconazole-treated (cytochrome P-450 enzyme-inhibited) swiss albino mice respectively. In vehicle-treated group, an enhancement in immobility time was observed at 3 h and 6 h after l...

Objective: The Losartan potassium mucoadhesive buccal tablet were prepared using mucoadhesive polymers such as Carbopol 940P, pectin, sodium CMC, Sodium alginate, HPMC K4M, HPMC K15M and HPMC K100M in alone and in combination as release retarding agent to prolong the drug release and to avoid first pass metabolism. Methods: The mucoadhesive buccal tablets were prepared by direct compression met...
