Abstract
The effects of candesartan (30 microg/kg i.v.) and PD123319 (10 mg/kg i.v.) on changes in systemic arterial pressure in response to angiotensin II (AngII) were investigated in the anesthetized mouse. Intravenous injections of AngII caused dose-related increases in systemic arterial pressure. Pressor responses to AngII were attenuated by candesartan but were not altered by PD123319. Neither candesartan nor PD123319 had a significant effect on baseline systemic arterial pressure or on the increase in arterial pressure in response to norepinephrine. The present results suggest that increases in systemic arterial pressure in response to AngII in the anesthetized mouse are mediated by AT1 receptors and that AT2 receptors do not modulate the pressor response to AngII.
