ANTIHYPERTENSIVE EFFECT OF β‐1‐RECEPTOR BLOCKADE AND β‐2‐RECEPTOR STIMULATION IN ESSENTIAL HYPERTENSION

Abstract
The antihypertensive effect of practolol, a beta-1-blocker, alone and in combination with a beta-2-stimulating drug, salbutamol, has been studied in a double-blind cross-over trial on 19 patients. Practolol treatment induced a significant BP reduction, while the addition of salbutamol failed to give any further decrease.
