Inhibition and Induction of Drug Metabolism (Involving

1/06/2000 · Abstract. The ability of modafinil to affect human hepatic cytochrome P450 (CYP) activities was examined in vitro. The potential for inhibition of CYP1A2, CYP2A6, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP2E1, CYP3A4/5, and CYP4A9/11 by modafinil (5–250 μM) was evaluated with pooled human liver microsomes.
