Brief Summary

Patients with endoscopically diagnosed active duodenal ulcer disease were enrolled in a randomized, double-blind, parallel and positive-controlled trial. They were randomly assigned into two groups, 10 mg/day ilaprazole and 20 mg/day omeprazole, to be treated for up to four weeks and be seen at week 1, 2 and 4. The primary endpoint was the ulcer healing rate at week 4. Healing of ulcer was determined by its resolution from active to scarring stage. Symptoms relief was evaluated as secondary end points by using a graded score. Safety and tolerability were evaluated on basis of clinical assessments.
