Abstract
BACKGROUND: Status epilepticus (SE) is an emergent neurologic condition that carries a high risk of morbidity and mortality. Intravenous brivaracetam (IV BRV) may be an alternative anticonvulsant against status epilepticus, although the sparseness of controlled studies on the topic limits its recommendation for this indication. OBJECTIVES: This systematic review aimed to determine the efficacy and safety of IV BRV in the treatment of status epilepticus. METHODS: A comprehensive literature search was conducted until December 2019 through several electronic databases (PubMed, Google Scholar, Scopus, OpenGrey, ScienceDirect, HERDIN, Epistemonikos, CENTRAL, ClinicalTrials.gov) to identify relevant studies. Studies that involved adult patients with SE who were given IV BRV were considered for inclusion in this review. RESULTS: From a total of 34 studies identified, 5 uncontrolled studies with 77 patients were included in this review. Thirty-seven out of 77 patients (48%) with SE responded to IV BRV. Reported time to seizure cessation may be immediate from a few minutes to several hours after IV BRV treatment. Patients manifested with significant disability on Glasgow outcome scale (Median: 3) and modified Rankin scale (Mode: 5). Six patients [somnolence (5), worsening seizures (1)] had treatment emergent adverse events. CONCLUSIONS: Limited evidence from 5 uncontrolled studies involving a limited number of patients suggests that IV BRV may be efficacious and safe in terminating seizures among patients with SE or refractory SE. Further studies employing either prospective, controlled trials or registry-based study designs are essential to determine the definitive role of IV BRV in patients with SE.
