Levetiracetamum is a derivative of pyrrolidone (S-enantiomer of alpha-ethyl-2-oxo-1-pyrrolidine-acetamide), whose chemical structure differs from known antiepileptic drugs. In vitro studies have shown that levetiracetam affects intraneuronal Ca2+ levels by partially inhibiting the current through N-type Ca2+ channels and reducing the release of Ca2+ from intraneuronal stores. It also partially reverses…
