    Abstract:
    A multicenter, double-blind, placebo-controlled study was carried out to determine whether the synthetic prostaglandin E1 analog misoprostol is effective in preventing gastric and duodenal lesions induced by nonsteroidal anti-inflammatory drugs. Two hundred fifty-six patients under nonsteroidal anti-inflammatory drug treatment (diclofenac, naproxen, piroxicam, ibuprofen, indomethacin, ketoprofen, or tiaprofenic acid) for osteoarthritis, rheumatoid arthritis, or other rheumatic diseases were included in the study. None of the patients had patent gastroduodenal damage at entry (0 to 3 mucosal erosions or subepithelial hemorrhages on endoscopy). Patients were randomly assigned to treatment with misoprostol 400 micrograms/d (M 400), misoprostol 800 micrograms/d (M 800) or a placebo. Results of the follow-up endoscopy on day 28 in the 186 evaluable patients showed that gastric erosions were significantly less common (p < or = 0.02) in the two misoprostol groups (5% and 2% in the M 400 and M 800 groups respectively) than in the placebo group (19%). Similar small numbers of patients in the three groups had gastric subepithelial hemorrhages or duodenal lesions. Three patients developed gastric ulcers in the placebo group, versus none in the misoprostol groups. Misoprostol therapy did not modify the efficacy of the nonsteroidal antiinflammatory agent on pain or other rheumatologic manifestations. Diarrhea occurred in 1%, 10%, and 5% of patients in the M 400, M 800, and placebo groups, respectively. In conclusion, misoprostol given in combination with a nonsteroidal anti-inflammatory agent for 28 days significantly reduced the incidence of gastric erosions in a random sample of patients with a variety of rheumatic diseases. The daily dosage associated with the best risk/benefit ratio may be 400 micrograms/day.
