Perampanel
Identification
- Summary
Perampanel is a non-competitive AMPA glutamate receptor antagonist used to treat partial-onset seizures with or without secondarily generalized seizures, and as adjunctive treatment of primary generalized tonic-clonic seizures in patients with epilepsy.
- Brand Names
- Fycompa
- Generic Name
- Perampanel
- DrugBank Accession Number
- DB08883
- Background
Perampanel is a noncompetitive AMPA glutamate receptor antagonist. It is marketed under the name Fycompa™ and is indicated as an adjunct in patients over 12 years old for the treatment of partial-onset seizures that may or may not occur with generalized seizures. The FDA label includes an important black-boxed warning of serious or life-threatening behavioral and psychiatric reactions in patients taking Fycompa™.

- Contraindications & Blackbox Warnings
Avoid life-threatening adverse drug eventsImprove clinical decision support with information on contraindications & blackbox warnings, population restrictions, harmful risks, & more.Avoid life-threatening adverse drug events & improve clinical decision support.- Pharmacodynamics
Perampanel is involved in inhibiting neuronal excitation in the central nervous system leading to such effects as decreased pyschomotor performance.
- Mechanism of action
The exact mechanism of action of perampanel in seizures is not yet determined, but it is known that perampanel decreases neuronal excitation by non-competitive ihibition of the AMPA receptor.
Target Actions Organism AGlutamate receptor 1 antagonistHumans - Absorption
After oral adminitration, perampanel is absorbed rapidly and completely.
- Volume of distribution
The volume of distribution of perampanel was not quantified.
- Protein binding
Perampanel is 95-96% plasma protein bound with most binding to the plasma proteins α1-acid glycoprotein and albumin.
- Metabolism
Perampanel is highly metabolized by CYP3A4 and/or CYP3A5 primary oxidation and by sequential glucuronidation.
- Route of elimination
Perampanel is eliminated mostely in the feces (48%) and to a lesser exten in the urine (22%).
- Half-life
Perampanel has a long elmination half-life of about 105 hours.
- Clearance
In healthy patients, perampanel has a clearance of about 12 mL/min.
- Adverse Effects
Improve decision support & research outcomesWith structured adverse effects data, including: blackbox warnings, adverse reactions, warning & precautions, & incidence rates.Improve decision support & research outcomes with our structured adverse effects data.- Toxicity
The FDA label includes an important warning of serious or life-threatening behavioral and psychiatric adverse reactions including aggression, hostility, irritability, anger, and homicidal thoughts in patients taking perampanel.
