Effect of Ritodrine on the Bladder Capacity in Unanaesthetized Pigs

Abstract
A cystometric investigation was carried out in unanesthetized pigs. During i.v. ritodrine infusion (10, 30 and 50 .mu.g/kg per min) a dose-dependent and significant increase of the bladder capacity was obtained. A concomitant significant elevation of the heart rate followed the administration of the drug. [Ritodrine is a .beta.2-adrenoceptor stimulator.].
