Misoprostol, a synthetic analog of prostaglandin E1, inhibits gastric acid production and is cytoprotective at doses well tolerated by patients in preliminary trials. This multicenter double-blind study was performed in out-patients with endoscopically demonstrated duodenal ulcers, to compare the efficacy in ulcer healing and the safety of two dosages of misoprostol and placebo. Up to six antacid tablets daily were permitted for pain. 308 patients enrolled and were randomized to three treatment groups: placebo, misoprostol 50 micrograms and misoprostol 200 micrograms. After two weeks of treatment, the three groups had similar percentages of patients with complete ulcer healing. However, after four weeks, 76.6% of patients taking misoprostol 200 micrograms q.i.d. had complete healing, compared with 42.6% on misoprostol 50 micrograms q.i.d. and 51% on placebo (P less than 0.001, 200 micrograms versus placebo). Patients taking misoprostol 200 micrograms used less antacid than the others. Diarrhea, mild and self-limiting, was present in 13% of the 200 micrograms group versus 5% on placebo. We conclude that misoprostol 200 micrograms q.i.d. is effective, safe and well tolerated in the treatment of duodenal ulcers. |
