Mechanisms of action of keppra (levetiracetam)?

Not completely known: However, it is hypothesized that it binds to a pre-synaptic glycoprotein that inhibits calcium channels affecting conduction across the synapse. Hope this answers your question and best of luck!

Not known: The best info i could find on this is on the wikipedia.Com website and reads as follows : the exact mechanism by which Levetiracetam acts to treat epilepsy is unknown. However, the drug binds to a synaptic vesicle glycoprotein, sv2a, [26] and inhibits presynaptic calcium channels.[27] this is believed to impede impulse conduction across synapses.[28].
