Consumer:

Consumer information for this interaction is not currently available.ADJUST DOSE: Coadministration with moderate inhibitors of CYP450 3A4 may significantly increase the plasma concentrations of ivacaftor, which is primarily metabolized by the isoenzyme. In study subjects, ivacaftor peak plasma concentration (Cmax) and systemic exposure (AUC) increased by approximately 2.5- and 3.0-fold when it was administered concomitantly with fluconazole, a moderate CYP450 3A4 inhibitor. When lumacaftor/ivacaftor was coadministered with ciprofloxacin, another moderate CYP450 3A4 inhibitor, lumacaftor Cmax and AUC decreased by 12% and 14%, respectively, while ivacaftor Cmax and AUC increased by 29% each. These changes are not considered clinically significant. Physiologically based pharmacokinetic (PBPK) simulations suggest that coadministration with moderate CYP450 3A4 inhibitors may increase elexacaftor AUC by 1.9- to 2.3-fold and tezacaftor AUC by approximately 2.1-fold. MANAGEMENT: Please consult manufacturer's product labeling for complete dosing information. For ivacaftor - The dosage for patients 6 years or older should be reduced to 150 mg once daily when used with moderate CYP450 3A4 inhibitors (2 to
