Clinical experience with prazosin hydrochloride in arterial hypertension

Abstract

Of 24 hypertensive patients treated with prazosin hydrochloride, a new vasodilator hypotensive drug with alpha blocking properties, 20 showed a standing blood pressure of less than 140/90 mmHg after six weeks therapy. Five patients had mild, 13 moderate and six severe hypertension. In 11 patients the drug was used alone and in 13 it was combined with thiazides, beta-blockers, clonidine or debrisoquine. Side effects were trivial. Two cases of severe renovascular hypertension responded excellently and one with malignant hypertension is showing a similar good response. The drug can be well combined with thiazides, beta-blockers and clonidine.
