    Abstract:
    UNLABELLED: One hundred and eight patients with an endoscopically documented healed duodenal ulcer (DU) participated to a multicentre, randomized, double-blind, long-term study. The study was planned with the aim to compare the efficacy of nizatidine 150 mg with ranitidine 150 mg in preventing relapse during the 2 years following the DU healing. Fifty four patients were assigned to each treatment. Endoscopic examinations were scheduled at 6, 12 and 24 months. Clinical evaluations were performed every two months. Routine laboratory tests were investigated at the beginning of the study and at each of the scheduled endoscopies. STATISTICS: chi-squared test with Yate's correction, Student's t test for unpaired data, Wilcoxon Rank Sum test and Logrank test. Twenty five patients dropped-out: 15 in the nizatidine and 10 in the ranitidine group. The cumulative relapse rate was 18% for nizatidine and 21% for ranitidine treatment (p:ns). Both drugs resulted safe, as only minor side effects were registered. IN CONCLUSION: nizatidine is as effective and safe as ranitidine in the long-term (2 year) treatment of DU.
