Abstract
A new H2-receptor antagonist, nizatidine (150 mg h.s.), was compared with placebo as maintenance therapy in a randomized, parallel, double-blind, one-year study of 513 patients with recently healed duodenal ulcer. Endoscopies were performed at 0, 3, 6, and 12 months and at unscheduled times if symptoms of active peptic ulcer disease were present. Cumulative ulcer recurrence rates for nizatidine and placebo were 13 versus 40% at 3 months, 24 versus 57% at 6 months, and 34 versus 64% at 12 months. The differences were significant (p less than 0.001) at each treatment period. Smokers in both treatment groups had significantly greater recurrence rates than non-smokers. Symptoms of peptic ulcer disease were significantly less in nizatidine-treated patients in the first 3 months of treatment. Adverse events, including those related to peptic ulcer disease, occurred more frequently in placebo-treated patients. Nizatidine proved to be safe and effective in preventing recurrences of duodenal ulcer.
