Summary

Oseltamivir dosing in infants \< 3 months of age is based on a single pharmacokinetic study in 20 infants from a single center. This dataset is limited by a lack of robustness, because only 1 sample was collected from each participant. The investigators obtained two blood samples each from infants receiving oseltamivir after obtaining informed consent from the infant's parents. The investigators propose to analyze the blood samples to determine the amount of oseltamivir in the infant's blood. Measurement of these values will increase the understanding of the absorption and elimination of oseltamivir in preterm and term infants, and improve our ability to provide the correct doses to this high risk population.

Conditions

• Prematurity of Fetus

Interventions

Type	Name	Description
DRUG	Oseltamivir	Treatment dose was oseltamivir 3 mg/kg/dose by mouth (PO) twice daily. Prophylactic dose was oseltamivir 1 mg/kg/dose PO once daily to infants \< 28 weeks postmenstrual age (PMA), 1 mg/kg/dose PO twice daily to infants 28 - 38 weeks PMA, and 3 mg/kg/dose PO once daily to infants \> 38 weeks PMA. Dosing in infants \< 28 weeks PMA was chosen based on unpublished data from Acosta et al. This data was obtained from phone contact with Dr. Peter Gal, co-author of the study. Dosing in infants 28 - 38 weeks PMA was chosen based on published data from Acosta et al.1 Dosing in infants \> 38 weeks PMA and less than 3 months postnatal age was chosen based on data from Kimberlin et al. Dosing in infants \> 38 weeks PMA and greater than 3 months postnatal age was per the recommendations of the Advisory Committee on Immunization Practices of the United States Department of Health and Human Services.
