Maintenance treatment with budesonide 6 mg versus 9 mg once daily in patients with Crohn's disease in remission.

Abstract

BACKGROUND: In previous trials, budesonide 6 mg/day was able to prolong the time to relapse in patients with quiescent Crohn's disease and budesonide 9 mg/day was effective in active disease with limited side effects. The aim of this study was to compare the effectiveness of budesonide 9 mg vs 6 mg once daily on the maintenance of remission and occurrence of adverse events. METHODS: Double-blind, randomised trial in patients with Crohn's disease in remission. Patients were randomised to receive 6 mg/day or 9 mg/day of budesonide (Budenofalk) without concomitant treatment for Crohn's disease. Endpoints were the time to relapse and relapse rates after one year. RESULTS: Seventy-six patients were randomised to 6 mg/day and 81 patients to 9 mg/day. Survival analysis showed no differences in the time to relapse. One-year relapse rates were not significantly different (6 mg group 24%; 9 mg group 19%). Any adverse event was reported in 61 and 68% of patients in the 6 mg and 9 mg groups, respectively; none of the 12 serious adverse events were drug related. CONCLUSION: The one-year relapse rates were low and not significantly different between the group of patients treated with budesonide 6 mg vs 9 mg/day. Also, time to relapse and the number of adverse events were similar in both treatment groups.
