About
Levetiracetam XR (Extended Release) is an antiepileptic drug (AED) primarily used in the treatment of various seizure disorders. Its precise mechanism of action is not fully understood but is believed to involve binding to the synaptic vesicle protein 2A (SV2A) in the brain, which modulates neurotransmitter release and helps to normalize neuronal excitability. The extended-release formulation allows for once-daily dosing, which can improve patient adherence and provide more consistent drug levels throughout the day, reducing fluctuations that might trigger seizures. Levetiracetam is effective as monotherapy or adjunctive therapy for partial-onset seizures, and as adjunctive therapy for myoclonic seizures in patients with juvenile myoclonic epilepsy and primary generalized tonic-clonic seizures. It is generally well-tolerated compared to some older AEDs, with a favorable pharmacokinetic profile and minimal drug-drug interactions.
