Nizatidine) Oral Solution
Axid® (nizatidine) Oral Solution Description: Nizatidine (USP) is a histamine H2-receptor antagonist. Chemically, it is N-[2-[[[2-[(dimethylamino)methyl]-4-thiazolyl]methyl]thio]ethyl]-N'-methyl-2-nitro-1,1- ethenediamine. The structural formula is as follows: Nizatidine has the empirical formula C12H21N5O2S2 representing a molecular weight of 331.47. It is an off-white to buff crystalline solid that is soluble in water. Nizatidine has a bitter taste and mild sulfur-like odor. Axid® Oral Solution is formulated as a clear, yellow, oral solution with bubble gum flavor and each 1 mL contains 15 mg of nizatidine. Axid® Oral Solution also contains the inactive ingredients methylparaben, propylparaben, glycerin, sodium alginate, purified water, sodium chloride, saccharin sodium, sodium citrate dihydrate, citric acid anhydrous, sucrose, bubble gum flavor, artificial sweetness enhancer, and sodium hydroxide. Clinical Pharmacology in Adults: Nizatidine is a competitive, reversible inhibitor of histamine at the histamine H2-receptors, particularly those in the gastric parietal cells. Antisecretory Activity—1. Effects on Acid Secretion: Nizatidine significantly inhibited nocturnal gastric acid secretion for up to 12 hours. Nizatidine also significantly inhibited gastric acid secretion stimulated by food, caffeine, betazole, and pentagastrin (Table 1). Table 1.

Comparative Effects of Cimetidine and Famotidine on the Vagally Stimulated Acid Secretion in the Isolated Mouse Whole Stomach
Comparative Effects of Cimetidine and Famotidine on the Vagally Stimulated Acid Secretion in the Isolated Mouse Whole Stomach Kazuo Watanabe1, Shingo Yano1, Masayuki Yamamoto1 and Shoko Kanaoka2 1Laboratory of Chemical Pharmacology, Department of Drug Evaluation and Toxicological Sciences, Faculty of Pharmaceutical Sciences, Chiba University, 1-33, Yayoi-cho, Inage-ku, Chiba 263, Japan 2Research Institute for Wakan-Yaku, Toyama Medical and Pharmaceutical University, Toyama 930-01, Japan Received July 15, 1992 Accepted December 10, 1992 ABSTRACT-We investigated the effects of cimetidine and famotidine on the acid secretory response to elec trical vagal stimulation, bethanechol and histamine in the isolated mouse whole stomach preparation. The acid secretion elicited by electrical vagal stimulation at the position of the esophagus (10 Hz, 0.3 msec, 10 V for 5 min) was reproducible by repeated stimulation in each preparation, and it was abolished by tetrodo toxin, atropine and hexamethonium. This vagally stimulated acid secretion was abolished by cimetidine (3 mM), while it was only partly inhibited by famotidine (10-100 ƒÊM). Histamine (100 ƒÊM)-induced acid secre tion was inhibited by cimetidine and famotidine, and the doses of these drugs required for complete inhibi tion were 3 mM and 10 ƒÊM, respectively. In contrast, bethanechol (10 ƒÊM)-induced acid secretion was slight ly reduced by famotidine (1-100 ƒÊM), but markedly reduced by cimetidine (3 mM). In the guinea pig ileum, millimolar concentrations of cimetidine and famotidine shifted the dose-response curve of the contractile response to acetylcholine rightward. These findings suggest that the inhibitory effect of cimetidine on the vagally stimulated or bethanechol-induced acid secretion is elicited at least partly through mechanisms different from H2-antagonism. -

Study design: A double blind, double dummy, randomized, comparative study. Place and Duration of Study: Global Liver and Gastroenterology Centre, Bhopal, India, between March 2010 and October 2010. Methodology: A total of 100 patients were enrolled, including 50 with endoscopically and histologically proven gastritis and other 50 with peptic ulcer (over 5 mm in diameter). Each group was randomized to receive either lafutidine or rabeprazole tablet and their corresponding competitor placebo dummy tablet, for a period of 4 weeks. Gastritis/ulcer cure rates confirmed by endoscopic histology, symptom response and Helicobacter pylori (H. Pylori) eradication were compared among the two drugs Results: Complete cure of gastritis was observed in all the patients (100%) treated with lafutidine and 95.24% [20/21; 95% CI: 76.18 to 99.88%] patients treated with rabeprazole. Complete cure of ulcer was observed in 72.0% (18/25, 95% CI = 50.61 to 87.93%) and 79.16% (19/24, 95% CI = 57.85 to 92.87%) patients treated with lafutidine and rabeprazole respectively. There was no significant difference in gastritis/ulcer cure rate and symptom response rate between the two treatment groups at the end of the study. -
