    Abstract:
    The effects of the AT1 and AT2 receptor blockers candesartan and PD123319 on hemodynamic responses to angiotensin II (AngII) were investigated in the anesthetized rat. Injections of AngII caused dose-related increases in systemic arterial and in hindquarters perfusion pressure that were reduced by candesartan. The inhibitory effects of candesartan were insurmountable, and a vasodepressor or vasodilator response to AngII was not unmasked. The AT2 receptor antagonist PD 123319 had no effect on increases in systemic arterial and hindquarters perfusion pressure in response to AngII. The present results suggest that pressor responses to AngII are mediated by the activation of AT1 receptors, and that AT2 receptors do not appear to modulate hemodynamic responses to AngII in the anesthetized rat.
