ibuprofen ⇔ imatinib
Applies to: ibuprofen and Gleevec (imatinib)
MONITOR: Coadministration with imatinib may increase the plasma concentrations of drugs that are substrates of CYP450 2C9, 2D6 and/or 3A4. The mechanism is decreased clearance due to inhibition of these isoenzymes by imatinib. According to the manufacturer, imatinib increased the mean peak plasma concentration and area under the concentration-time curve of simvastatin (a CYP450 3A4 substrate) by 2- and 3.5-fold, respectively. Data for other substrates are not currently available, although human liver microsome studies indicate that imatinib is a potent competitive inhibitor of all three isoenzymes.
MANAGEMENT: Caution is advised if imatinib must be used concomitantly with medications that undergo metabolism by CYP450 2C9, 2D6 and/or 3A4, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever imatinib is added to or withdrawn from therapy.
