Abstract

The effects of exogenous serotonin on pentagastrin-stimulated gastric acid secretion and antral motility were evaluated with regard to inhibition kinetics and receptor mediation. Conscious gastric fistula dogs were used. Serotonin inhibited the acid secretion dose-dependently, whereas the antral motility was initially stimulated and thereafter inhibited. The inhibition of secretion was counteracted by different β-adrenergic blocking drugs and methysergide, whereas the inhibition of antral motility was blocked by methysergide and indomethacin. Dose-response analysis showed inhibition of non-competitive types. This study supports the concept of differences in the regulation of gastric acid secretion and motility, but further experiments with simultaneous registration are required.
