Primary Purpose: Treatment
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

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • 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.

Secondary Outcome Measures:
  • 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
