Oseltamivir pharmacokinetics, dosing, and resistance among children aged <2 years with influenza.

ABSTRACT:

Background

Children <2 years of age are at high risk of influenza-related mortality and morbidity. However, the appropriate dose of oseltamivir for children <2 years of age is unknown.

Methods

The National Institute of Allergy and Infectious Diseases Collaborative Antiviral Study Group evaluated oseltamivir in infants aged <2 years in an age-de-escalation, adaptive design with a targeted systemic exposure.

Results

From 2006 to 2010, 87 subjects enrolled. An oseltamivir dose of 3.0 mg/kg produced drug exposures within the target range in subjects 0-8 months of age, although there was a greater degree of variability in infants <3 months of age. In subjects 9-11 months of age, a dose of 3.5 mg/kg produced drug exposures within the target range. Six of 10 subjects aged 12
