Retrospective Evaluation of Perampanel in a French Neurology and Epileptology Department (Hospices Civil de Lyon)
Perampanel is a non-competitive antagonist of the AMPA (
 2-amino-3-(5-méthyl-3-hydroxy-1,2-oxazol-4-yl)) propanoïc acid receptors which was approved
 by the European Medicines Agency as adjunctive treatment for partial-onset seizures in
 patients 12 years and older, in 2012. The aim of this study is to evaluate effectiveness and
 safety of perampanel as add-on treatment in patients with refractory epilepsy.

 The investigators retrospectively collected and analyzed the data of patients with refractory
 epilepsy who had been treated with perampanel between May of 2014 and April of 2015. In
 total, one hundred and ten patients were included (mean age 41 [SD = 15.2]). The mean
 duration of epilepsy was 25 years (SD = 14.4). The mean perampanel dose was 5.7 mg/d (SD =
 2.3). The retention rate was 77% at 6 months and 61% at 12 months. After 6 months, the
 responder rate was 35.5%. Eight patients (7.3%) became seizure free. Adverse effects were
 reported in 60 patients (54.5%). Most common side effects were behaviour disturbance (22.7%),
 dizziness (15.5%), asthenia (11.8), somnolence (10%) and ataxia (9.1).

 -  Patients with refractory focal epilepsy

 -  Initiation of perampanel between 05/2014 and 04/2015

 Exclusion Criteria:
