Adding carbamazepine to lamotrigine.
General information- Lamotrigine is principally metabolised by UDP-glucuronosyltransferases.
- Carbamazepine is principally metabolized by CYP3A4, and is a potent inducer of CYP1A2, CYP2C9, CYP3A4 and UDP-glucuronosyltransferases.
Start carbamazepine- Start carbamazepine with a daily dose of 200 mg and increase dose based on serum concentration if necessary. Check lamotrigine effect after 2 weeks of therapy and adapt dose if necessary.[6] [7]
Cave- Abrupt stop of carbamazepine can cause serious lamotrigine rash as lamotrigine levels increase.[8]
- Carbamazepine likely speeds the metabolism of lamotrigine, but the clinical significance is unclear.[9][10]
- Lamotrigine may increase blood levels of carbamazepine metabolites, which can result in neurotoxicity (data about this are contradictory).[9][10]
- These two agents have less significant pharmacologic interactions than do lamotrigine and valproate.[9][10]
