Ranitidine vs cimetidine: short-term treatment of gastric ulcer.

We compared the clinical effectiveness and endoscopic results of ranitidine and cimetidine treatment; 71 outpatients, all affected with benign gastric ulcer, were selected for the study (43 type I, 7 type II and 21 type III, according to Johnson's classification). The patients were treated randomly for 4 weeks with ranitidine (300 mg daily) or cimetidine (1 g daily). An endoscopic examination was repeated within 3 days after the end of the treatment. Clinical checks were performed weekly in order to monitor the clinical course of pain and antacid consumption, according to the patient's needs. The patients who did not demonstrate complete healing on endoscopic examination were treated for an additional 4 week period. At the end of this 4 week period, another endoscopic examination was done. Thirty-six patients treated with ranitidine and 33 with cimetidine completed the first period of therapy. The two groups were homogeneous with regard to sex, age, duration of disease, smoking habits, alcohol consumption, and type and size of ulcer. Ranitidine and cimetidine treatments did not demonstrate any significant difference with regard to ulcer healing after the 4th or the 8th week of therapy. Both ranitidine and cimetidine were less effective in healing type I than type II and III G.U., at the 4th week of treatment. No significant differences between the two groups were noted with regard to pain or weekly antacid consumption. No significant side effects were reported.
