Study Overview

Treatment of Zollinger-Ellison Syndrome With Prevacid

The purpose of this study is to study the safety and efficacy of high dose Prevacid in the long-term treatment of patients who secrete abnormally large amounts of gastric acid.

The aim of this protocol is to study the medical management of acid hypersecretory states including Zollinger-Ellison using Prevacid. The immediate objective is to heal peptic ulcers and eliminate symptoms and in the long term to prevent relapse of symptoms, lesions and complications. Other objectives include observation of the efficacy in controlling gastric acid production and of the safety of high dose, long-term use of Prevacid.
