Efficacy of famotidine in the healing of active benign gastric ulceration: Comparison of nonsteroidal anti-inflammatory- or aspirin-induced gastric ulcer and idiopathic gastric ulceration

Seventy-one of 85 consecutive patients with endoscopically confirmed active benign gastric ulcers completed an 8-week study to evaluate the effects on healing of famotidine 40 mg given as a single dose at night. The healing rate in the 48 patients in whom the ulcers were associated with nonsteroidal anti-inflammatory drug (NSAID) or aspirin (ASA) use was compared with that in the 23 patients with idiopathic ulcers. Endoscopy, symptom assessments, antacid use, hematology, and serum chemistry were performed at weeks 4 and 8 of treatment. Famotidine 40 mg at bedtime healed 63 (89%) of the 71 ulcers at 8 weeks; the healing rate for NSAID/ASA-associated ulcers was 46 (96%) of 48, which was significantly greater than that for idiopathic ulcers (17 of 23; 74%) (P = 0.0119). Of the 54 patients who returned a questionnaire 1 to 2 years after completing the study, 20% were still taking an NSAID/ASA (mainly for cardiovascular prophylaxis). About half of the patients surveyed were taking anti-ulcer medication. None of these patients had experienced any serious ulcer complication. The results of this study suggest that differentiating NSAID/ASA-induced ulcers from idiopathic ulcers may be important with regard to healing rates and duration of therapy.
