( 2.3 , 7.1 ) • Strong CYP3A4 Inducers: Avoid strong CYP3A4 inducers. If coadministration cannot be avoided, increase the dosage of XTANDI. ( 2.3 , 7.1 ) • Avoid coadministration with certain CYP3A4, CYP2C9, or CYP2C19 substrates for which a minimal decrease in concentration may lead to therapeutic failure of the substrate. In cases where active metabolites are formed, there may be increased exposure to the active metabolites. ( 7.2 ) 7.1 Effect of Other Drugs on XTANDI Strong CYP2C8 Inhibitors The coadministration of XTANDI with gemfibrozil (a strong CYP2C8 inhibitor) increases plasma concentrations of enzalutamide plus N-desmethyl enzalutamide, which may increase the incidence and severity of adverse reactions of XTANDI. Avoid the coadministration of XTANDI with strong CYP2C8 inhibitors. If the coadministration of XTANDI with a strong CYP2C8 inhibitor cannot be avoided, reduce the dosage of XTANDI [see Dosage and Administration ( 2.3 ), Clinical Pharmacology ( 12.3 )]. Strong CYP3A4 Inducers The coadministration of XTANDI with rifampi…
