Pharmacokinetic parameters of total radioactivity, TAK-448, and M-I in the plasma of rats after coadministration of [14C]TAK-448 and protease inhibitor cocktail
Parameters for total radioactivity are calculated from the mean plasma concentrations for three animals. Parameters for TAK-448 and M-I are calculated from the concentrations for the pooled samples from three animals. Numbers in parentheses denote percentage of total radioactivity. Data are taken from Fig. 4.
