Background and Date of Approval

Brivaracetam is an antiepileptic drug developed by the U.S. Food And Drug Administration and initially approved for treating epilepsy.

Mechanism of Action of undefined

Brivaracetam works by selectively binding to synaptic vesicle protein 2A (SV2A) in the brain. This protein is involved in the release of neurotransmitters, including gamma-aminobutyric acid (GABA) and glutamate, which play a major role in regulating brain activity. By binding to SV2A, this drug helps stabilize the release of these neurotransmitters, reducing excessive electrical activity in the brain and preventing seizures.

Uses of undefined

Brivaracetam is used to treat partial-onset seizures in patients with epilepsy. Partial-onset seizures, also known as focal seizures, are a type of epileptic seizure that begins in a specific area or focus within one hemisphere (side) of the brain. These seizures are caused by their localized onset, meaning they originate in a specific region of the brain rather than affecting the entire brain simultaneously. 

undefined Drug administaration and Dosage available

Brivaracetam is administered directly into the vein intravenously (IV). It is available as a powder for reconstitution, and a physician will prepare and administer the medication through a vein. The IV infusion is usually given over a period of one to two hours.
