Prazosin 129-137 renin Canis lupus familiaris 48-53 2541403-2 1989 Renin stimulus-response curves were determined by a stepwise reduction of renal artery pressure down to 70 mm Hg (1) under control conditions, (2) during a bilateral common carotid occlusion combined with an intrarenal prazosin infusion, and (3) during an intrarenal methoxamine infusion. Prazosin 219-227 renin Canis lupus familiaris 0-5 6264792-2 1981 The effect of alpha-adrenoceptor blockade by phenoxybenzamine (POB) or prazosin on renin secretion rate (RSR) was studied in pentobarbital-anesthetized dogs in which renal perfusion pressure was held constant with an adjustable aortic clamp. Prazosin 71-79 renin Canis lupus familiaris 83-88 7049441-6 1982 After 7 days of hydralazine or prazosin administration, plasma renin activity remained elevated and blood volume increased from baseline values. Prazosin 31-39 renin Canis lupus familiaris 63-68 7008886-6 1980 Prazosin administration was associated with a significant increase in heart rate and increase in plasma renin activity. Prazosin 0-8 renin Canis lupus familiaris 104-109 7008886-10 1980 We conclude that prazosin is not a unique peripheral vasodilator since hypotensive doses are associated with an increase in heart rate and plasma renin activity. Prazosin 17-25 renin Canis lupus familiaris 146-151 7008886-2 1980 The effect of a hypotensive dose of intravenous prazosin (0.2 mg/kg) on heart rate and plasma renin activity was evaluated in anaesthetized mongrel dogs pretreated with indomethacin. Prazosin 48-56 renin Canis lupus familiaris 94-99 975613-7 1976 Prazosin lowered plasma renin activity to 62% (P less than 0-025) of the control value whereas diazoxide raised plasma renin activity to 178% (P less than 0.05) of the control value. Prazosin 0-8 renin Canis lupus familiaris 24-29 975613-9 1976 The combination of vasodilatation and low renin activity observed following the administration of prazosin is unique, and may have clinical significance if these factors reduce the vascular complications of hypertension.
