Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Influenza

Intervention: Oseltamivir (Drug); Oseltamivir (Drug); Placebo (Drug)

This randomized, double-blind, multi-center study of Tamiflu (Oseltamivir) will evaluate the efficacy against viral activity, the effectiveness in resolving the disease symptoms, and the safety and tolerability in patients with influenza. Patients with (H1N1) 2009 influenza strain or influenza A are eligible for this study. Patients will be randomized to one of four treatment regimens. Patients will receive oral doses of either 75 mg (adults) or 150 mg (adults) of study drug twice daily for 5 or 10 consecutive days. The dose will be body weight-adjusted for pediatric patients.
