Calcitonin versus cimetidine or De-Nol in gastric ulcer treatment. An endoscopically controlled trial.

110 patients with benign gastric ulcer and concomitant joint diseases (rheumatoid arthritis, osteoarthrosis) were treated in a comparative short-term clinical trial to assess the relative efficacy of calcitonin (daily 100 MRC of salmon calcitonin intramuscularly), cimetidine (daily 1000 mg orally) and colloidal bismuth subcitrate (De-Nol-four times a day in doses of 5 ml diluted with 15 ml of water). Groups of patients were comparable according to age, sex, duration of ulcer disease, smoking habits, gastric acid secretion and mean ulcer size. The ulcer healing was controlled endoscopically after 2 and 4 weeks of the treatment.
