title: Comparison of nizatidine and cimetidine as once-nightly treatment of acute duodenal ulcer. Nizatidine Multicenter Duodenal Ulcer Study Group.
abstract: Nizatidine, a new H2-receptor antagonist for the treatment of duodenal ulcer disease, was compared with cimetidine in an 8-wk, randomized, double-blind, multicenter clinical trial. Patients were randomly allocated to receive either nizatidine 300 mg h.s. or cimetidine 800 mg h.s. Patients were treated for 8 wk, regardless of the healing status of their ulcers. An endoscopy was performed at Wk 2, 4, and 8. Healing rates with nizatidine 300 mg h.s. were numerically, but not statistically significantly, superior to those with cimetidine 800 mg h.s. at each treatment period. Ulcer healing rates at Wk 2, 4, and 8 were 41% (78/191), 73% (130/179), and 81% (145/179) for nizatidine and 33% (60/184), 67% (116/174), and 75% (126/168) for cimetidine, respectively. Symptoms of peptic ulcer disease were similarly reduced at each treatment period by nizatidine and cimetidine. Patients with healed ulcers at either Wk 2 or Wk 4 were continued on therapy and an endoscopy was performed at Wk 8. Ulcer recurrence occurred in 10% of nizatidine-treated and 19% of cimetidine-treated patients at Wk 8 (p = 0.085). The observation of recurrence of duodenal ulcer while patients were receiving full-dose H2-receptor antagonist therapy has not been reported previously.
