title: A comparison of the effects of treatment with either famotidine 40 mg or cimetidine 800 mg nocte on gastric acid secretion and serum gastrin.
abstract: The effects on gastric acid secretion and serum gastrin of 4 weeks treatment with famotidine 40 mg nocte or cimetidine 800 mg nocte (at 2200 h) were studied in 16 patients with previous duodenal ulcer. Patients were studied before commencing therapy, on days 5, 12 and 26 of treatment, and on days 3, 10 and 24 after completion of therapy. In contrast to cimetidine, basal and pentagastrin-stimulated gastric acid secretion measured 12 h after dosing was significantly inhibited during treatment with famotidine. In addition, with famotidine there was inhibition of stimulated gastric acid secretion at 3 and 24 days after completion of treatment. Fasting serum gastrin measured 12 h after dosing was not significantly altered by either drug.
