The peripheral hemodynamic effects of SZL-49, a prazosin analog capable of selectively inactivating theα1a-adrenoceptor subtype, was evaluated in the conscious rat. One hour after SZL-49 administration, total peripheral vascular resistance and arterial blood pressure significantly decreased and cardiac output and heart rate increased. Twenty-four hours after SZL-49, blood pressure returned to control preinjection levels while peripheral resistance remained decreased and cardiac output and heart rate were elevated. The phenylephrine dose-response curves for mean arterial blood pressure and total peripheral vascular resistance were shifted to the right but the maximal responses were not decreased. These data show that theα1areceptor plays a role in the tonic maintenance of arterial blood pressure. Theα1breceptor appears to participate in the response to exogenously administered agonists.
