The precise mechanism by which brivaracetam exerts its antiepileptic activity is unknown. Brivaracetam displays a high and selective affinity for synaptic vesicle protein 2A (SV2A) in the brain, which may contribute to the antiepileptic effect.
Brivaracetam is a prescription medication used with other medicines to treat partial-onset seizures in people 16 years of age and older with epilepsy. Brivaracetam belongs to a group of drugs called antiepileptics. These work by reducing the frequency of seizures.
This medication comes in a tablet and solution form and is usually taken 2 times a day by mouth with or without food. The brivaracetam tablets should be swallowed whole with liquid. Do not crush or chew brivaracetam tablets before swallowing.
This medication is also available in an injectable form to be given directly into a vein (IV) by a healthcare professional.

Brivaracetam Dosing: Adult
Partial onset seizures: Oral, IV: Initial: 50 mg twice daily; may decrease to 25 mg twice daily or increase up to 100 mg twice daily based on individual patient response and tolerability (maximum: 200 mg/day). Note: Use injection when oral administration is temporarily not feasible; clinical study experience with brivaracetam injection is limited to 4 consecutive days of treatment.
Dosage adjustment for concomitant therapy with rifampin: Increase brivaracetam dosage by up to 100% (ie, double the brivaracetam dose).
Discontinuation of therapy: Reduce gradually; it has been recommended to reduce the dose by 50 mg/day on a weekly basis with the final week of treatment at the dose of 20 mg/day (Brivlera Canadian product labeling 2016).
|Refer to adult dosing. Consider starting at the low end of the dosage range.|
|Partial onset seizures: Adolescents ≥16 years: Oral, IV: Refer to adult dosing.|
Dosing: Renal Impairment
Mild to severe impairment: No dosage adjustment necessary.
End-stage renal disease requiring dialysis: Use is not recommended (has not been studied).
Dosing: Hepatic Impairment
|Mild to severe impairment (Child Pugh classes A, B, and C): Initial: 25 mg twice daily, up to a maximum of 75 mg twice daily.|
Injection: Administer IV over 2 to 15 minutes; may administer undiluted or diluted with NS, LR, or D5W.
