Detailed Description:

Omeprazole is a highly effective drug for the treatment of gastroesophageal reflux disease (GERD) in infants. Infants, aged 0-12 months, require a non-standard dose of omeprazole. Due to this fact extemporaneous formulations of omeprazole are administered to these infants. The oral bioavailability of omeprazole in nonproprietary formulations may be unpredictable and produce variable degrees of drug exposure. The dose range for GERD management in pediatric studies using omeprazole is 0.3 - 3.5 mg/kg/day.

Dosing information, aged-specific pharmacodynamic and pharmacokinetic data are not available in infants, aged 0-12 months. Two adult studies at healthy volunteers suggest that an omeprazole suppository is an effective dosage form.This study is designed to evaluate and to compare the efficacy, the pharmacodynamics and the pharmacokinetics of oral and rectal omeprazole treatment in infants with gastroesophageal reflux disease.
