Precautions
Patient w/ severe cardiac disease (e.g. MI, heart failure), conduction problems (e.g. marked 1st degree AV block or sick sinus syndrome w/o pacemaker), Na channelopathies (e.g. Brugada syndrome), structural heart disease. Childn. Hepatic and renal impairment. Pregnancy and lactation.
Pregnancy-Lactation

Increased systemic exposure w/ strong inhibitors of CYP2C9 (e.g. fluconazole) and CYP3A4 (e.g. ketoconazole, itraconazole, clarithromycin, ritonavir) enzymes. Reduced systemic exposure w/ rifampicin, phenobarbital, phenytoin, carbamazepine. Risk of PR prolongation w/ class I antiarrhythmics, lamotrigine, pregabalin, carbamazepine, eslicarbazepine.

Mechanism of Action
Lacosamide is a functionalised amino acid structurally related to serine. Its precise mechanism of action is unknown, however in vitro studies suggest that it selectively enhances the slow inactivation of Na channels w/o affecting fast inactivation. This results in stabilisation of hyperexcitable neuronal membranes and inhibition of repetitive neuronal firing. Additionally, it may affect collapsin response mediator protein-2 (CRMP-2), a protein involved in neuronal differentiation and axonal growth.
