자니틴정(니자티딘)

Nizatidine capsules are indicated for up to 8 weeks for the treatment of active duodenal ulcer. In most patients, the ulcer will heal within 4 weeks. Nizatidine capsules are indicated for maintenance therapy for duodenal ulcer patients at a reduced dosage of 150 mg h.s. after healing of an active duodenal ulcer. The consequences of continuous therapy with nizatidine for longer than 1 year are not known. Nizatidine capsules are indicated for up to 12 weeks for the treatment of endoscopically diagnosed esophagitis, including erosive and ulcerative esophagitis, and associated heartburn due to GERD. Nizatidine capsules are indicated for up to 8 weeks for the treatment of active benign gastric ulcer. Before initiating therapy, care should be taken to exclude the possibility of malignant gastric ulceration.

Nizatidine capsules are contraindicated in patients with known hypersensitivity to the drug. Because cross sensitivity in this class of compounds has been observed, H 2 -receptor antagonists, including nizatidine, should not be administered to patients with a history of hypersensitivity to other H 2 -receptor antagonists.

Pregnancy Teratogenic Effects Pregnancy category B Oral reproduction studies in pregnant rats at doses up to 1500 mg/kg/day (9000 mg/m 2 /day, 40.5 times the recommended human dose based on body surface area) and in pregnant rabbits at doses up to 275 mg/kg/day (3245 mg/m 2 /day, 14.6 times the recommended human dose based on body surface area) have revealed no evidence of impaired fertility or harm to the fetus due to nizatidine. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
