Lamotrigine pathway published in Pharmacogenetics and Genomics

The PharmGKB lamotrigine pathway has been recently published in the journal Pharmacogenetics and Genomics.The publication, written by Taraswi Mitra-Ghosh, now at Auburn University, and Samuel Callisto of the Univeristy of Minnesota along with collaborators, including former PharmGKB Scientific Curator Julia Barbarino, reviews both the pharmacokinetics and pharmacodynamics of lamotrigine. Lamotrigine is an antiseizure drug which has also been approved for the treatment of bipolar disorder. It is extensively metabolized in the liver primarily by UGT enzymes. Although the exact pharmacodynamic effects of lamotrigine remain unclear, it is thought that it may act as an antagonist of voltage-gated sodium channels and voltage-gated calcium channels.Adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported in patients treated with lamotrigine. A number of alleles at the HLA locus which have been linked to lamotrigine-related adverse events are also reviewed in this paper.

The pathway, including a clickable image, is also freely available on the PharmGKB website.
