Valyl3‐oxytocin has similar circulatory effects in man to those of Syntocinon (synthetic oxytocin). On intravenous administration, it caused a rise in limb blood flow and in pulse rate and a fall in blood pressure. It had a direct vasodilator effect on limb blood vessels. Valyl3‐oxytocin was 1.5 to 2 times more potent than Syntocinon in terms of its circulatory effect in man. The circulatory effects of valyl3‐oxytocin were less readily antagonized by vasopressin than are those of Syntocinon.
