A cystometric investigation was carried out in unanaesthetized pigs. During intravenous infusion of ritodrine (10, 30 and 50 microgram/kg/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.
