[Mechanisms of action of nonachlazine].

In animals with a ligated anterior descending left coronary artery, a single administration of nonaclazine (5 mg/kg bw) leads to a marked increase in the coronary blood flow and to an improvement in cardiovascular system function. Administration of nonachlazin for 7 days helps normalize the electrophysiological and hemodynamic characteristics and produces a beneficial effect on the myocardial blood flow and contractility. Interaction of nonaclazine with adrenergic receptors does not appear to have any decisive significance in the drug action mode.
