Effects of beta-blocking agent Metipranolol on metabolic variables in patients with ischemic heart disease, hyperkinetic syndrome, hyperthyreosis and in healthy subjects.

Abstract

Metabolic effects of Metipranolol, a new beta adrenergic blocking agent, have been studied in patients with ischemic heart disease, hyperkinetic syndrome, hyperthyreosis and in healthy subjects. Administration of the drug (30 mg per day for one week) resulted in the decrease of noradrenaline excretion, blood free fatty acid level, and in lowering of blood pressure and heart rate, particularly in patients with ischemic heart disease and hyperkinetic syndrome. These alterations were accompanied by alleviation of clinical symptoms. It is suggested that Metipranolol by suppressing the activity of sympathetic nervous system and thereby diminishing lypolysis, exerts favourable clinical effects, most probably related to diminution of myocardial oxygen consumption.
