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 dysfunct...

The aim of this study was to evaluate the effects of lercanidipine or barnidipine on echocardiographic parameters, in hypertensive, type 2 diabetics with left ventricular hypertrophy. One hundred and forty-four patients were randomized to lercanidipine, 20 mg/day, or barnidipine, 20 mg/day, in addition to losartan, 100 mg/day, for 6 months. We evaluated: blood pressure, fasting plasma glucose (...

Oct 28, 2011. There was no significant difference between groups in the incidence of. These results demonstrate that combination amlodipine/losartan . amlodipine 5 mg once daily or losartan 50 mg once at the end of treatment, with no difference between mild to moderate hypertension was defined as the. 3 Answers Posted in: high blood pressure, amlodipine, losartan Answer: I. They both have diffe...

OBJECTIVES To evaluate the efficacy and safety of losartan and enalapril in pediatric kidney transplant recipients. MATERIALS AND METHODS A retrospective review was performed in 31 pediatric kidney transplant recipients who were treated with losartan (50 mg/d, oral) for 1 to 6 months because of mild hypertension and persistent proteinuria. All patients were treated concurrently with enalapril...

The present work comprises the formulation and evaluation delivery system of transdermal drug with a view of developing and preparing a losartan potassium releasing system utilizing natural oils as permeation enhancers for transdermal applications. Matrix systems were prepared by using polyvinyl pyrrolidine and ethyl cellulose (EC) polymers by incorporating dibutyl phthalate as plasticizer and ...

Losartan potassium, valsartan, telmisartan, irbesartan, eprosartan mesylate and candesartan cilexitil, the angiotensin II receptor antagonists, were analyzed in bulk substances and in tablets: Lorista tablets 50 mg, Diovan tablets 160 mg, Micardis tablets 20 mg, Aprovel tablets 300 mg, Teveten tablets 600 mg and Blopress tablets 16 mg. The conditions for identification by HPLC method in a gradi...

A general aim of the research was to develop a technology of manufacturing microspheres with losartan potassium as an active substance, and Eudragit L30D55 as a matrix with the use of spray drying technique. During the first step of the study, optimal values of parameters in spray drying process were established (i.e., operating temperature, peristaltic pump performance, aspiration value). Thos...

The aim of this study was to explore the influence of combination therapy in different administration time on antihypertensive efficacy and blood pressure variability in patients with essential hypertension. A total of 86 patients with stage II to III essential hypertension were randomly divided into 4 groups: taking indapamide and losartan potassium together in the morning or in the evening 2 ...

Two methods, spectrophotometric and chromatographic-densitometric ones, were developed for determination of losartan potassium, quinapril hydrochloride and hydrochlorothiazide in pharmaceutical preparations. Spectrophotometric method involved derivative spectrophotometry and zero order spectrophotometry. The measurements were carried out at lambda = 224.0 nm for quinapril, lambda = 261.0 nm for...

A prospective, open label, parallel group and randomized study was conducted to see the effect of enalapril and losartan on proteinuria in type 2 diabetic nephropathy patients. 18 patients (proteinuria 2 0.5 gm/day and serum creatinine <3 mg/dL) were selected and then randomly grouped to receive enalapril (5-40 mg/day, n=10) and losartan (25-200 mg/day, n=8) in increasing dose for 16 weeks. No ...
