<prompt> The recently approved antiepileptic drug lacosamide acts by:Inhibiting synaptic vesicular proteinInhibing CRMP protineInhibing GABA metabolismInhibing glutamate release  <response>: Ref: Katzung, 14th ed. pg. 417 CRMP is Collapsing Response Mediator Protein, which causes neuronal excitotoxicity by releasing BDNF Brain Derived Neurotropic Factor. The drug Lacosamide acts by inhibiting CRMP protein, thereby causing protective action against neuronal excitotoxicity.
