Popis: Objective The purpose of this study was to examine the pharmacokinetics, safety, and tolerability of zanamivir in children. Background Zanamivir is a potent inhibitor of viral neuraminidase that is effective against both influenza A and B infections. Methods A pediatric study was conducted to examine the pharmacokinetics, safety, and tolerability of zanamivir in children who had signs of respiratory illness. Twenty-four children aged 3 months to 12 years received zanamivir administered as a single, orally inhaled, 10-mg dose either by nebulizer (in patients ® (in patients ≥5 years of age). Serum and urine zanamivir concentrations were analyzed both before dosing and from 0.5 to 8 hours after dosing. Results The rate and extent of absorption of zanamivir were independent of the inhalation formulation or of the patient's age. Median maximum serum concentrations were 47 ng/mL in younger patients (aged ≥3 months to Conclusions Results of the present study suggest that a 10-mg dose of zanamivir is safe and well tolerated when used in children who have signs and symptoms of respiratory illness.
