This study will be conducted in order to determine safety and efficacy esomeprazole,
lansoprazole and pantoprazole control stomach acid by measuring the stomach acid in men and
women of Hispanic origin who have GERD.
Official title: A Randomized, Open-Label, Comparative 3-Way Crossover Study of 24-Hour Intragastric pH Profile of Once Daily Oral Administration of Esomeprazole 40 mg, Lansoprazole 30 mg, and Pantoprazole 40 mg at Steady State in Hispanic Patients With Symptomatic GERD
Study design: Treatment, Randomized, Open Label, Dose Comparison, Crossover Assignment, Safety/Efficacy Study
Primary outcome: To compare the pharmacodynamic efficacy in controlling intragastric pH following administration of esomeprazole 40 mg, lansoprazole 30 mg, and pantoprazole 40 mg taken orally, once daily in Hispanic patients with symptomatic GERD.
Compare nocturnal intragastric pH in Hispanic patients with GERD
Compare integrated acidity (IGA) using 24-hour monitoring period among Hispanic patients with GERD
Assess the short-term safety and tolerability of PPIs being studied in Hispanic patients
Minimum age: 18 Years.
Maximum age: 69 Years.
