Effects of famotidine on gastric mucus of the rat.
The influence of famotidine on the production of gastric mucus was studied at experimental level. We measured the quantity of the intracellular mucus, the surface adherent mucus gel thickness, and the biosynthesis of prostaglandin E2 (PGE2) by the rat gastric mucosa, in pretreated animals. Both the intracellular mucus accumulation and the adherent mucus gel thickness revealed a highly statistically significant increase (P less than 0.0002). PGE2 assay showed that famotidine also led to a statistically significant increase (P = 0.02) of PGE2 in treated versus control animals. These findings raise the question of whether despite its common antisecretory pathway of action this H2-receptor antagonist could play a role in the protection of gastric mucosa. Further research is necessary to determine this.
