Abstract
BackgroundPerampanel is the latest anti-seizure medication introduced in the Philippines in 2015. This was initially approved as an adjunctive treatment for focal seizures and those with secondary generalization among individuals 12 years old and above. By March 2020, it has been approved also for generalized seizures and in children 4 years and above. The general objective of this research is to describe the clinical experience of Filipino child neurologists on the use of perampanel in children. MethodsThis is a cross-sectional descriptive study that surveyed child neurologists with review of medical records of children who have received perampanel as either an adjunctive therapy or monotherapy for epilepsy. ResultsThere were 65 patients included in the study aged 1 to 18 years with a mean age of 10.0 ± 5.2 years and a median of 10 years. Follow-up duration were between 2 weeks to more than a year. Perampanel was started in 98.5% as an add-on treatment between 5 months and 18 years of age. The responder rate is 69.2% (45/65), seizure-free rate is 29.2% (19/65), seizure-aggravation rate is 9.2% (6/65), and perampanel retention rate is 83.1% (54/65). Treatment emergent adverse events were noted in 53.8% of the children with somnolence (20.0%), gait problems (12.3%), weight gain (10.8%) and dizziness (9.2%) as the most common events experienced. Dizziness was experienced significantly more among children 12 to 18 years of age. ConclusionPerampanel is seen to be effective and relatively safe to use among Filipino children.
