Abstract
Levetiracetam an antiepileptic drug derived from pyrrolidones, alters intraneuronal calcium levels by reducing its release from intracellular stores, partially inhibits N-type calcium channels and partially reversed the reduction in GABA and glycine currents induced by Zinc and ?-carbolines. Levetiracetam has favorable pharmacokinetic and safety profiles that have made it a useful drug in the adjuvant management of uncontrolled partial seizures. This paper report 4 cases of patients managed with levetiracetam innovative, who presented intolerable adverse events and therapeutic failure by switching to generic levetiracetam, it is concluded that further local studies are required to corroborate the consequences of shift to generic levetiracetam that may affect treatment adherence and generate life-threatening situations such as status epilepticus.
