[Nizatidine versus ranitidine in the treatment of acute duodenal ulcer. Comparison of 300 mg nizatidine and 300 mg ranitidine in a single evening dose].

In a double-blind, endoscopically controlled study on 367 duodenal ulcer patients, we compared the clinical efficacy of 300 mg ranitidine nocte with that of 300 mg nizatidine nocte, which is known to reliably provide selective inhibition of nocturnal acid secretion. Nizatidine was administered to 183, ranitidine to 184 patients. Endoscopy was performed at the start of the study, as well as at 2, 4 and 8 weeks.

[Treatment of acute stomach ulcer with H2 receptor antagonists. A direct therapy comparison with 300 mg nizatidine nightly and 2 times 150 mg nizatidine with twice daily 150 mg ranitidine].

In this endoscopically controlled, double-blind study involving 242 patients with acute benign gastric ulcer, it was shown that the selective inhibition of nocturnal gastric acid secretion with 300 mg nizatidine administered on retiring represents an effective and reliable form of therapy. After four weeks of treatment, 90% of the patients receiving 300 mg nizatidine, no longer experienced nocturnal pain, in comparison with 83% receiving 2 X 150 mg nizatidine daily (n.s.
