| Abstract: | Perampanel is approved for adjunctive therapy of focal epilepsy with or without secondarily generalized seizures in patients aged >12 years. This narrative review uses real-world and clinical trial data to elucidate perampanel's role in the clinic. Audit data show good tolerability with perampanel and higher freedom-from-seizure rates in elderly vs younger patients. When using perampanel in elderly patients, special attention should be given to comorbidities and co-medication to avoid potential interactions or adverse events. Slower titration is generally recommended, and seizure control should be reassessed at a dose of 4 mg before further dose increases. Perampanel efficacy is similar in adolescents and adults; however, somnolence, nasopharyngitis, and aggression are more frequent in adolescents vs the overall population. Individualized and slow-dose titration can minimize adverse events. Low serum concentrations of perampanel may occur in patients also receiving some enzyme-inducing anti-epileptic drugs; a perampanel dose increase may be required. Adverse events of importance with perampanel include dizziness; anger, aggression, and hostile behavior (particularly in adolescents); and falls (particularly in patients >65 years). An individualized approach to dosing, including slower up-titration and bedtime dosing, reduces dizziness risk. Other drugs may cause or aggravate dizziness; reducing concomitant drugs may be necessary when up-titrating perampanel. It would seem clinically appropriate to give due consideration to avoiding use in patients with a history of anger or hostile/aggressive behavior. The possibility of such behaviors should be discussed with patients before starting perampanel, with monitoring during up-titration. Slower up-titration of perampanel in older patients helps reduce fall risk. [ABSTRACT FROM AUTHOR] |
