CONTEXT Beta-blockers have been shown to decrease cardiovascular risk in patients with hypertension and type 2 diabetes mellitus (DM); however, some components of the metabolic syndrome are worsened by some beta-blockers. OBJECTIVE To compare the effects of beta-blockers with different pharmacological profiles on glycemic and metabolic control in participants with DM and hypertension receivin...

Abstract Eight drugs blocking beta-adrenergic receptors activity (acebutolol, alprenolol, atenolol, oxprenolol, labetalol, metoprolol, propranolol and sotalol) were investigated through the use of thin-layer technique with its mobile phase containing surfactant. Assessment effect surfactant presence 1-propanol concentration in on retention separation solutes was then carried out wherein zone sh...

Metoprolol succinate is a widely used medication for the management of hypertension, heart failure, and angina. We report the case of a 36-year-old woman who developed erythema multiforme after administration of a low dose of this drug. She also presented with pruritic burning pain throughout her body accompanied by chills. While erythema multiforme has been reported with carvedilol, this is th...

CYP1A2, CYP2D6 and N-acetyltransferase activities were estimated in 100 patients with bladder cancer and 84 control subjects from measurements of theophylline, metoprolol and isoniazid and their metabolites in urine, respectively. The frequency of occurrence of slow acetylators of isoniazid and poor metabolizers of metoprolol were 16.7% and 1.2% in the control group and 16.3% and 2.0% in the ca...

To assess the safety of combined intervention in acute myocardial infarction, a pilot study of thrombolysis and beta-adrenergic blockade was performed. Twenty-five subjects were randomized to therapy with intravenous (IV) metoprolol and IV streptokinase (group 1) or to IV metoprolol (group 2) alone. Two-dimensional echocardiography was performed before intervention and five days later. The mean...

Resolution of binary mixtures of metoprolol and propranolol without sample pretreatment has been successfully achieved, using three different methods. The first method was based on application of Vierodt’s method that involves measurements of the absorbances at 222.6 and 213.4 nm for metoprolol and propranolol. Calibration graphs were established in the range of 1-70 μg/mL and 0.5-30 μg/mLfor m...

ISSN:0976-9374 In vitro in vivo correlation of metoprolol tartrate sustained release capsules were studied in this investigation. The half-life of metoprolol is 3 to 4 hours. Peak plasma concentrations vary widely and occur about 1.5 to 2 hours after a single oral dose. In this study, non pareil seeds were prepared and coated with metoprolol tartrate using polyvinyl pyrollidone and iso propyl a...

Beta-blockers are underutilised in heart failure because clinicians may be unsure whether all beta-blockers are useful, how therapy should be initiated and whether beta-blockers are contraindicated in some patients. Bisoprolol, carvedilol and metoprolol succinate have been clearly proven to reduce mortality and hospitalisation in patients with Class II to IV heart failure; limited evidence also...

1. Oral and intravenous administration of metoprolol to adult spontaneously hypertensive rats (SHR) with established hypertension lowered arterial blood pressure within 4 days of treatment. 2. Steady state plasma concentrations of metoprolol were similar to those of patients during anti-hypertensive treatment with this drug. 3. The neuroeffector function of portal veins of SHR treated orally fo...

An accurate and precise liquid chromatographic method was developed for the simultaneous estimation of telmisartan and metoprolol succinate in tablets. The chromatographic analysis was performed on Nucleosil C18 Column (250*4.6mm 5μ particle size) with mobile phase consisting of acetonitrile and potassium di-hydrogen orthophosphate buffer (pH2.8) in the ratio 60:40v/v, at a flow rate of 0.8ml/m...
