The influence of aging on the metabolism of antipyrine (AP) and hexobarbital enantiomers (R-HB and S-HB) with and without phenobarbital (PB) induction was investigated in a longitudinal study in rats aged 6, 12, 24 and 30 months. The metabolic clearances of AP (Cl(m AP)), R-HB (Cl(m R-HB)) and S-HB (Cl(m S-HB)) were used as indicators for P450...
