Dabrafenib Mesylate <> Tegretol

Relevance: 10.05.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

CarBAMazepine may reduce the blood levels of dabrafenib, which may make the medication less effective in treating your condition. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

GENERALLY AVOID: Coadministration with potent inducers of CYP450 2C8 and/or 3A4 may decrease the plasma concentrations of dabrafenib, which is primarily metabolized by these isoenzymes. Administration of rifampin (600 mg once a day), a potent CYP450 3A4 and moderate CYP450 2C8 inducer, with dabrafenib (150 mg twice a day) for 10 days resulted in a decreased dabrafenib AUC (34%) and Cmax (27%). The AUC of the metabolite hydroxy-dabrafenib was not affected; however, the AUC increased by 73% for the metabolite carboxy-dabrafenib and decreased by 30% for desmethyl-dabrafenib.

MANAGEMENT: Concomitant use of dabrafenib with potent CYP450 2C8 or 3A4 inducers should generally be avoided. Otherwise, patients should be closely monitored for potential loss of efficacy of dabrafenib.
