Prostaglandin 15 (R) 15-methyl-E2 methyl ester for suppression of gastric acidity in gravida at term

During the second hour after giving 100 mug of orally administered prostaglandin 15 (R) 15-methyl-E(2) methyl ester in the pregnant patient at term a noticeable reduction in basal gastric acid secretion took place. At this dose no excessive uterine stimulation was observed. Prostaglandin 15 (R) 15-methyl-E(2) methyl ester could prove of value in the preoperative preparation of the pregnant patient before anaesthesia for reducing the incidence of acid regurgitation.
