Sixty-nine outpatients with endoscopically confirmed duodenal and prepyloric (DU) or gastric ulcers (GU) completed a 4-week double-blind trial with either cimetidine, 1 g/day, or trimipramine, 50 mg/day. Ulcer healing was assessed by endoscopy at 4 weeks. At the end of the study 14 of 23 patients with DU treated with cimetidine and 13 of 25 treated with trimipramine had healed ulcers. In the patients with GU 7 of 11 ulcers (cimetidine) and 4 of 10 (trimipramine) healed. The differences in healing rates between the two treatment groups were not statistically significant, either in DU and GU groups separately or in the total material. The number of pain attacks per week decreased and the symptoms improved significantly in both treatment groups in DU, GU, and totally. Both drugs were well tolerated, but two patients in each treatment group developed a slight increase in serum transaminases. No serious side effects occurred. The study suggests trimipramine as an alternative drug to the well-established drug cimetidine in the treatment of duodenal and possibly also of gastric ulcer.

Maintenance therapy for duodenal ulcer: a randomized controlled comparison of seven forms of treatment.
Am J Med
March 1992
Department of Medicine, University of Hong Kong, Queen Mary Hospital.
Purpose: We performed a randomized controlled trial to compare the efficacy of seven forms of maintenance treatment of duodenal ulcer, including a mealtime regimen of antacids.
Patients And Methods: We randomized 785 patients with healed duodenal ulcer to receive: (1) no treatment; (2) mealtime antacids with an acid-neutralizing capacity of 80 mmol/day; (3) an antidepressant, trimipramine 25 mg; (4) an anticholinergic, pirenzepine 50 mg; (5) cimetidine 200 mg; (6) cimetidine 400 mg; (7) ranitidine 150 mg; or (8) sucralfate 1 g twice a day. Symptomatology and side effects were assessed every 2 months and endoscopy was performed every 4 months up to 1 year.
Effects of antidepressants on alcohol-induced gastric mucosal injury in rats.

October 1989
Dept. of Surgery, Faculty of Medicine, Valladolid, Spain.
The purpose of the present report is to study the effects of antidepressants such as trimipramine, amitriptyline, maprotiline and mianserin on severe gastric mucosal lesions produced by ethanol in comparison with cimetidine (H2-antihistamine) and dexchlorepheniramine (H2-antihistamine). The percentage of macroscopic mucosal lesions caused by alcohol affects 15% of the mucosal area. But pretreated with cimetidine the affected area was 9.

Department of Pharmacology, Laboratorios Dr. Esteve, S.A., Barcelona, Spain.
The results of five different experiments carried out on isolated gastric mucosa were evaluated. These were: 1) Effects of antisecretory agents on (H+) and (K+) in a histamine-stimulated (4 x 10(-5)M) preparation. 2) Effects on (H+) in a preparation stimulated by dibutyryl cyclic adenosine monophosphate (dbcAMP) (6 x 10(-4)M).

Pharmacol Toxicol
April 1989
Department of Clinical Microbiology, Central Hospital, Hillerød, Denmark.
A series of conventional anti-ulcer drugs, tricyclic antidepressants and neuroleptics (and some CNS non-active isomers) were tested in vitro for possible inhibition of Campylobacter pylori. These bacteria are claimed to play an etiological role in peptic ulcer disease, at least in gastritis B. While cimetidine, famotidine, ranitidine and pirenzepine were inactive, all the antipsychotic agents and their isomeric derivatives were active to various degrees with IC50 of 26-59 microM.
