Perampanel Alone May Help Children With Epilepsy

What was studied

This paper reviewed published studies on using perampanel alone (monotherapy) in children with epilepsy. The authors searched PubMed following PRISMA guidelines and included 12 studies published between 2016 and 2026 that met their inclusion criteria.

Together, the studies included 850 children ages 2 to 16 years. Most had focal seizures. The review combined results from 8 retrospective studies and 4 prospective observational studies. Perampanel maintenance doses ranged from 1.5 to 12 mg per day.

What they found

Across the included studies, perampanel used alone was associated with high responder rates, seizure freedom, and retention on treatment over 3, 6, and 12 months. At 12 months, the pooled estimates were 79% for retention on treatment, 78% for responder rate, and 72% for seizure freedom. The review also described the safety profile as tolerable in children. Most of the children studied had focal seizures, so the results mainly reflect that group.

Limits of the evidence

This review does not show that perampanel caused these outcomes. The included studies were non-randomized, including observational studies, which limits causal conclusions. Most participants had focal seizures, so it is less clear how well these findings apply to children with other seizure types. The abstract also does not give detailed side effect numbers or direct comparisons with other seizure medicines.

For families and caregivers

For families, this review suggests that perampanel could be an effective initial single-medicine option for some children with epilepsy, especially since most children studied had focal seizures. The results are encouraging, with high reported rates of response, seizure freedom, and staying on treatment, but the evidence is not as strong as it would be from randomized trials.

What to watch next

Stronger evidence would come from randomized studies that compare perampanel monotherapy with other seizure medicines in children.
