Abstract | GOALS: BACKGROUND: PPIs have been used therapeutically for many years, and shown great efficacy in accelerating ulcer healing. Currently researches are focused on more potent PPIs. Some preclinical studies have shown that ilaprazole might be such a new substitute. STUDY: 235 patients with at least 1 endoscopically diagnosed active duodenal ulcer were enrolled in a randomized trial. Patients were randomized into 4 groups (5, 10, and 20 mg/d ilaprazole, with 20 mg/d omeprazole as positive control) and treated for up to 4 weeks. Forty patients accepted continuous 24-hour pH measurements after the fifth dose. The primary endpoint was ulcer healing rate at week 4. RESULTS: The efficacy analyses were based on 235 patients. At week 4, 86.4%, 93.1%, 86.4%, and 89.8% patients treated with 5 mg ilaprazole, 10 mg ilaprazole, 20 mg ilaprazole, and 20 mg omeprazole once daily, respectively had ulcers healed (P=0.59). The majority of patients (>70%) became asymptomatic after 4 weeks treatment. Both drugs with stipulated dosages exhibited similar efficacy and safety profiles. Gastric acid suppression increased with increasing dose of ilaprazole in pH study. CONCLUSIONS:
