* Topiramate induces CYP3A4 and is an inhibiter of CYP2C19.
* Carbamazepine is principally metabolized by CYP3A4 (also CYP2C8), but is also a potent inducer of CYP1A2, CYP3A4 and UDP-glucuronosyltransferases.
* This combination of drugs may have possible synergistic effects. However, the pharmacokinetic drug interactions will influence the plasma levels. Dose adaptation will be recommended for this combination.

* Carbamazepine can increase topiramate clearance. Add carbamazepine according to the general dosing advice and check the effects of topiramate and increase dose if necessary. <ref name=”medicatiebewaking”> Schalekamp T. et al, Interacties met Psychofarmaca, Stichting Health Base, Houten, 2002. </ref> <ref name=”bazire”> Bazire S, Pshychotropic Drug Directory 2007, HealthComm UK Limited, Aberdeen, 2007. </ref>
