Which metabolic pathway is associated with lamotrigine interactions according to the material?

Explanation:
Lamotrigine is cleared mainly through glucuronidation by UDP-glucuronosyltransferase (UGT) enzymes, especially UGT1A4. This glucuronidation pathway is where most clinically relevant interactions occur—most notably with valproic acid, which inhibits UGT-mediated glucuronidation and raises lamotrigine levels, increasing the risk of serious rash. The CYP450 system, P-glycoprotein, and SLC transporters are not the primary routes for lamotrigine metabolism, so interactions via those pathways are less expected.
