The effect of simultaneous administration of levarterenol and phentolamine on renal blood flow
VM Cimmino, EL Bove, LC Argenta, JW Brown and MM Kirsh
The effect of simultaneous administration of levarterenol and phentolamine
upon renal blood flow was studied over a 3-hour period in 22 mongrel dogs.
The infusion of levarterenol alone produced a fall in renal blood flow that
ranged from 28 to 58% from the baseline value. When both drugs were
administered simultaneously, renal flow fell only 17 to 22% from baseline
(p less than 0.05). From these studies we conclude that the simultaneous
administration of levarterenol and phentolamine in optimal ratios maintains
renal blood flow near baseline levels.
