Learn More- 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
Learn about our commercial Adverse Effects data.
Learn More- 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.
