Duodenal ulcer 42 Sources: http://ca.gsk.com/media/592906/zantac.pdf	Primary	Approved 8429	ZANTAC 150 Approved Use ZANTAC® (ranitidine hydrochloride) Tablets and Injection are indicated for the treatment of duodenal ulcer, benign gastric ulcer, reflux esophagitis, post-operative peptic ulcer, Zollinger-Ellison Syndrome, and other conditions where reduction of gastric secretion and acid output is desirable. These include the following: • the treatment of nonsteroidal anti-inflammatory drug (NSAID)- induced lesions, both ulcers and erosions, and their gastrointestinal (GI) symptoms and the prevention of their recurrence; • the prophylaxis of GI hemorrhage from stress ulceration in seriously ill patients; • the prophylaxis of recurrent hemorrhage from bleeding ulcers; • the prevention of Acid Aspiration Syndrome from general anaesthesia in patients considered to be at risk for this, including obstetrical patients in labour, and obese patients.
