Abstract
Evidence has accumulated in recent years from animal experiments that drugs inhibiting acid secretion can stimulate the growth of gastric mucosa. This was first shown in our laboratories, when rats were treated with high doses of metiamide, a precursor of cimetidine1–3. It was later confirmed with cimetidine4 and was subsequently also observed with prolonged antacid treatments5. In all these studies a hyperplasia of the parietal cells was observed. The functional correlate was an acid rebound following discontinuation of drug therapy1,3. It is likely that this trophic effect is mediated by gastrin, the established trophic hormone of the gastrointestinal tract6, since in the rat every high dose of a histamine H2-antagonist or antacid leads to a transient gastrin releasel.
