Pharmacokinetics
The mean oseltamivir and oseltamivir carboxylate in the fasting and fed groups had similar plasma concentration–time profiles (Figs. Mean (mean ± SD) plasma concentration vs. time profiles of oseltamivir and oseltamivir carboxylic under fasting conditions (pharmacokinetic concentration sets). Mean (mean ± SD) plasma concentration vs. time profiles of oseltamivir and oseltamivir carboxylic underfed conditions (pharmacokinetic concentration sets).
