Purpose: Lamotrigine is mainly metabolized by UGT1A4 and UGT2B7, both of which are expressed in the blood-brain barrier. Polymorphisms of said UDPglucuronosyltransferases, (UGTs) that affect enzyme activities have been reported. This study investigated the relationship between these polymorphisms and its therapeutic effect in 55 depressed patients who did not respond to adequate treatment during an 8-week treatment of lamotrigine augmentation using an open-study design. Patients and Methods: The subjects were 55 depressed patients who had already shown insufficientc response to at least 3 psychotropics including antidepressants, mood stabilizers, and atypical antipsychotics.
