[Comparative evaluation of the clinical action of a series of beta-adrenergic blockaders].
A comparative clinical study of the efficacy of Benzoral, Trasicor, Viskene, Aptene, Eraldine and Inderal was conducted in the ischaemic heart disease patients. Their antiarrhythmic and antianginal effect was determined, as well as their optimum therapeutic dosages, the activity of their specific beta-adrenolytic properties, the effect of the drugs on the bronchi and the peripheral venous tone. Apart from the clinical study, electro- and polycardiography, functional pulmonary tests and the Schellong orthostatic test were used. All the drugs in question were found to produce a distinct specific beta-blocking effect. They are effective in cases of atrial and ventricular extrasystole, paroxysmal tachycardia, sinus tachycardia and tachyarrhythmic fibrillation, as well as for the prevention of anginal attacks and arrhythmic fibrillation. All the drugs produce a negative inotropic effect, Inderal--the strongest, Viskene and Benzoral--the weakest. All beta-blockers can impair bronchial patency in patients with bronchial obstruction. This effect is least pronounced with Eraldine that may be used as the drug of choice in such cases. In most cases the beta-blockers do not affect the peripheral venous tone, but in some cases they may reduce it.
