title: Cimetidine and placebo-cimetidine in the treatment of patients with chronic gastric ulcer (a multiclinical randomized double-blind comparative study).
abstract: The efficacy of a 4-week cimetidine treatment was examined by a double-blind randomized study in 37 outpatients with endoscopically verified chronic gastric ulcer. The patients received a daily dose of 3 times 1 tablet and, at night before going to bed 2 more tablet, thus a total amount of 1 g cimetidine, or cimetidine-placebo, but in case of complaints they could take in addition a mixed alkaline powder. Patients not recovering in response to a 4-week treatment, were then administered daily 5 tablets of cimetidine up to their complete recovery. Endoscopic, laboratory and clinical examinations were carried out every other week. As a result of a 4-week treatment, 56% of the cimetidine group recovered. The difference was not significant (P less than 0.2). The size of the ulcer and the intensity of the complaints were reduced significantly in both groups. The decrease in the size of the ulcer was significantly greater in the first two weeks of cimetidine treatment than in the cimetidine-placebo group (P less than 0.05). This favourable dynamics of ulcer healing was not felt in the second two weeks of treatment, and after four weeks there was no difference in the size of the residual ulcer to between the two groups. Cimetidine seemed to be a suitable drug for treating chronic gastric ulcer, since its healing rate proved to be better than that of placebo, the gain in weight also was favourable and there were no side-effects.
