  Purpose
The purpose of this study is to determine the area under the plasma concentration-time curve (AUC) of esomeprazole after single oral doses of 5 mg, 10 mg or 20 mg esomeprazole in pediatric patients 1 to 11 years-old inclusive with endoscopically-proven GERD.

Condition Intervention Phase
Endoscopically-Proven GERD Reflux Drug: esomeprazole magnesium Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Official Title: A Randomized, Open-Label Study to Evaluate the Pharmacokinetics of Single Oral Doses of Esomeprazole Magnesium in Pediatric Patients 1 to 11 Years-Old Inclusive With Endoscopically-Proven Gastroesophageal Reflux Disease (GERD)

Primary Outcome Measures:
  • Area under the plasma concentration-time curve (AUC) of esomeprazole after single oral doses of 5 mg, 10 mg and 20 mg esomeprazole in pediatric patients 1 to 11 years old inclusive with endoscopically-proven GERD. [ Time Frame: Day 1 ]

Secondary Outcome Measures:
  • The AUC(0-t), Cmax, tmax, and apparent volume of distribution during terminal phase (Vλz/F) of esomeprazole after single oral doses of 5 mg, 10 mg and 20 mg esomeprazole in pediatric patients 1 to 11 years-old inclusive with endoscopically-proven GERD. [ Time Frame: Day 1 ]
  • AUC, AUC(0-t), Cmax, tmax, t1/2λz of the 5-hydroxy and sulphone metabolites of esomeprazole after a single oral dose of 5 mg, 10 mg, and 20 mg esomeprazole in pediatric patients 1 to 11 years-old inclusive with endoscopically-proven GERD. [ Time Frame: Day 1 ]
  • Safety and tolerability after a single oral dose of esomeprazole in pediatric patients 1 to 11 years old inclusive with endoscopically- proven GERD. [ Time Frame: Day 1, Day 15 ]

Criteria

Inclusion Criteria:

  • Patients must be able to take solid or bland food (eg, applesauce).
  • Patients must weigh at least 8 kg and at the investigator's discretion be able to undergo extraction of an adequate volume of blood.
