The role of nifedipine in inducing the blockage of calcium slow channels in the smooth muscle cell of the esophagus is well known. The aim of our study was to evaluate the action nifedipine exerts upon acid secretion and gastrin release stimulated by intragastric titration with a peptone meal (pH 5.5) in 7 healthy adult males. Percentage gastrin variations(More)
