title: Healing and recurrence of active duodenal ulcer with nizatidine.
abstract: Nizatidine, a new H2-receptor antagonist for treatment of duodenal ulcer disease, was evaluated in a unique two-phase, placebo-controlled, randomized, double-blind, multicenter clinical trial. Patients received either 150 mg nizatidine twice daily or placebo for 4 weeks (phase I). If ulcer healing did not occur during phase I, patients were randomly reallocated to receive either 150 mg nizatidine twice daily or placebo for an additional 4 weeks (phase II). Patients with a healed ulcer continued on the same therapy. All patients were endoscoped at week 8. Healing rates at week 2 were 93 of 265 (35%) nizatidine-treated patients and 55 of 260 (21%) placebo-treated patients (p less than 0.001); at week 4, healing rates were 198 of 259 (76%) nizatidine-treated patients and 95 of 243 (39%) placebo-treated patients (p less than 0.001). In phase II, ulcer healing occurred in 46 of 86 (53%) nizatidine-treated patients and in 23 of 90 (26%) placebo-treated patients (p = 0.002). In patients who had a healed ulcer at previous endoscopies, 18 of 178 (10%) nizatidine-treated patients and 10 of 81 (12%) placebo-treated patients had a recurrence of duodenal ulcer. Smokers who had histories of previous ulcers were more likely to have an early recurrence.
