* Risperidone is principally metabolized by CYP2D6 to an active metabolite.
* 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.
