Abstract
We studied the oral gastric antisecretory activity of prostaglandin E2 in three groups of six normal volunteers. Each volunteer was studied twice, once after receiving prostaglandin E2 (0.5, 1.0, or 2.0 mg) and the other time after receiving placebo administered in a double-blind, randomized fashion. Gastric acid secretion was stimulated with a liquid protein meal from 1/2 to 1 1/2hr after drug administration. Acid secretion was quantitated using the technique of intragastric titration. Acid secretion after 0.5 mg of prostaglandin E2 was no different than after placebo administration, but 1.0 mg and 2.0 mg of prostaglandin E2 inhibited 58% (6.68±7.64 meq vs 14.67±6.75 meq, P2 in man is antisecretory with an ED50 of 1.1 mg.Keywords
