“Results Strongly dose-dependent augmented antiviral effect of the combination α-tocopherol and 0.625 mg/kg oseltamivir was demonstrated when α-tocopherol was administered simultaneously with oseltamivir : a pronounced decrease in mortality rate (a 78% protection), and a lengthening of mean survival time by 3.2–4 days.”
“When α-tocopherol was applied in courses starting five or two days before infection, its combination with oseltamivir was ineffective.”
