    Abstract:
    Advanced age is an established risk factor for gastrointestinal toxicity of nonsteroidal antiinflammatory drugs, and the duration of use of these agents in elderly patients should be kept as short as possible. A multicenter, double-blind, placebo-controlled trial was conducted to evaluate the efficacy of misoprostol in preventing gastrointestinal toxicity in elderly patients (> or = 65 years) given nonsteroidal antiinflammatory agents for no more than ten days. Patients who were to receive a nonsteroidal antiinflammatory agent for ten days to treat an acute rheumatic condition were randomly allocated to treatment with either a placebo or misoprostol in a dose of 200 micrograms bid. The primary efficacy criterion was the result of a gastroduodenal endoscopic evaluation done on day 10. The outcome of the rheumatic condition, changes in serum creatinine levels, and clinical safety were also evaluated. The study population included 208 subjects with a mean age of 81.4 +/- 6.4 years, of whom 81.3% were women. The misoprostol group (n = 104) and the placebo group (n = 104) were comparable at baseline. The incidence of endoscopically visible gastric lesions after ten days of nonsteroidal antiinflammatory drug therapy was significantly lower in the misoprostol group (25%) than in the placebo group (43%) (P = 0.001). In contrast, no statistically significant difference was found for the incidence of duodenal lesions between the two groups. The incidence of gastroduodenal ulcers was significantly lower (P < 0.021) in the misoprostol group (4.1%) than in the placebo group (13.5%). Changes in serum creatinine levels on day 10 versus baseline were similar in the two groups. The nonsteroidal antiinflammatory drug was well tolerated clinically when given alone or in combination with misoprostol.
