[Use of the adrenergic beta receptor blockader, visken, (prindolol) in arterial hypertension].

Visken (prindolol) was used in 42 patients. Its hypotensive effect was studied by the double-blind method. The hypotensive effect was encountered in 34 patients. With the administration of a placebo the arterial pressure became elevated, while after repeated prescription of the drug it again decreased significantly. Study of hemodynamics by radiocardiography in 18 patients treated with prindolol revealed no essential changes in the cardiac output, total peripheral resistance, rate of venous blood flow and volume of circulation.
