Summary of the mean (S.D.) pharmacokinetic parameters of oseltamivir and oseltamivir carboxylate after a single oral dose of oseltamivir (30 mg/kg) to adult fed rats (n = 3/group)
Oseltamivir was dosed either as a water solution, as a solution in milk, or as 125 mM aqueous Gly-Sar. Statistical analysis was performed on Cmax, tmax, AUC0–6h, and AUC0-∞ values; bovine milk (group 2) and Gly-Sar (group 3) treatments were compared with water (group 1). No statistically significant difference was observed.
