Study Evaluating the Pharmacokinetics of Doxylamine Succinate in Children

Phase 1

Completed

Conditions: Allergic Rhinitis
Upper Respiratory Infection

Interventions: Drug: Doxylamine Succinate USP

Registration Number: NCT00796315

Lead Sponsor: Procter and Gamble

Brief Summary: The primary goal of this study is to characterize the pharmacokinetics of doxylamine succinate in children ages 2 to \< 18 years. Once characterized, these pediatric pharmacokinetic data will be pooled with historical adult PK data from other studies to assess whether the existing Over-the-Counter (OTC)doses provide comparable systemic drug exposure as that associated with efficacy in adults.
