RT Journal Article SR Electronic T1 Cimetidine-resistant Zollinger-Ellison syndrome: successful management with ranitidine JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 256 OP 258 VO 129 IS 3 A1 F. M. Habal A1 S. J. Soldin A1 G. R. Greenberg YR 1983 UL http://www.cmaj.ca/content/129/3/256.abstract AB In a patient with the Zollinger-Ellison syndrome who had undergone vagotomy, pyloroplasty and, later, gastrojejunostomy, epigastric pain and stomal ulceration recurred despite the use of high doses (2700 mg/d) of cimetidine. Ranitidine, a new histamine H2-receptor antagonist, reversed all symptoms and healed the stomal ulcer without side effects, thus obviating the need for further surgery. Ranitidine may prove to be the drug of choice in the medical management of patients with the Zollinger-Ellison syndrome.
