title: [The vasoactive effects of captopril (SQ 14225). Preliminary research].
abstract: The Authors examined the behaviour of the humeral arterial pressure, of the heart frequency and of the muscular blood flow in inferior limbs. This study was performed before and after treatment with Captopril (SQ 14225), 100 mg per os, a selective inhibitor of the converting enzyme. Both resting blood flow (RBF) and maximal blood flow (NBF) were studied by Xenon 133 clearance. The A.A. observed that the drug induced a significant (P less than 0.01) increase of both RBF and MBF. Therefore,  the Authors hypothesize that the Captopril is able to produce peripheral vasodilatation, without any significant variation of the cardiac index and frequency. Such an effect is considered to depend not only upon the inhibited angiotensin II production, but also upon stimulation of bradikinins and prostaglandins.
