The behaviour of serum gastrin fasting levels was studied in 39 randomized patients with proven duodenal ulcer, 21 receiving cimetidine (1 g/day) and 18 placebo for 28 days. No significant variations of gastrin fasting values were found, but in four patients given cimetidine a relevant increase was observed at the end of the treatment. One out of 6 patients, previously treated with placebo, showed a marked increase of fasting gastrin levels after a second trial of cimetidine. No increase of G-17 was observed in the patients showing fasting hypergastrinemia after cimetidine. The present study seems to confirm some previous observations and it seems to suggest the possibility that in some patients cimetidine could induce hypergastrinemia.
