Product overview

Name Lamotrigine
Description Na2+ / K+ / Ca2+ channel inhibitor. Anticonvulsant.
Biological description Anticonvulsant. Inhibits voltage-dependent Na2+ channels, K+ and Ca2+ channels. Inhibits α4β2-nACh receptor mediated currents and reduces GABAA receptor transmission. Inhibits 5-HT, noradrenaline and dopamine uptake into synaptosomes (IC50 values are 474, 239 and 322 µM respectively). Shows anticonvulsant and anti-bipolar actions. Blood-brain barrier permeable.
