  • Long-term Medical(Non-surgical)Control of Gastric Acid Production Assessed From Time of Study Enrollment, up to 240 Months Post Enrollment.

    number of participants with control of gastric acid production

    up to 240 months from study enrollment

Secondary Outcomes (1)

Study Arms (1)

single group

EXPERIMENTAL

This is an open label, non-randomized, uncontrolled, single group study designed to treat patients with Zollinger-Ellison Syndrome and other hypersecretory conditions by controlling gastric acid production; to heal and prevent relapses of peptic ulcers and symptoms; to monitor the safety and efficacy of this treatment.

Drug: Lansoprazole (Prevacid)

Interventions

Lansoprazole 30mg capsules. dose is individualized to each subject based on gastric acid production. The range is 30 mg to 450 mg daily.

Also known as: Lansoprazole is marketed as Prevacid.
