Summary
Brief summary (as posted)
In patients with Zollinger-Ellison Syndrome the level of gastric acid is elevated. This increased level of gastric acid is what causes the symptoms of the disease. Certain types of medication can control the secretion of gastric acid. In this study there are details on how drugs known as antihistamines (H2 receptor antagonists) can control the levels of gastric acid secretion. The study describes; which patients are candidates for this research, what to do prior to initiating treatment, and the appropriate dose of antihistamine to be given. Initial doses of the medication will be given intravenously (injected through a vein) and later doses will be administered orally (by mouth). By following the procedure, researchers will be able to determine if there is a more effective route of drug administration, as well as the effectiveness of antihistamines in patients treated surgically for Zollinger-Ellison pancreatic tumors with mildly elevated gastric acid levels.
