Summary: Brain injury is the main cause of death and disability for patients surviving cardiac arrest resuscitation and seizures are diagnosed in up to a third of these patients. The investigators are proposing a pilot randomized placebo-controlled clinical trial to evaluate the safety and feasibility of perampanel use for post-cardiac arrest status epilepticus (PCARSE) prevention after cardiac arrest.

Summary: The purpose of this study is to determine the safety of Fycompa for injection after administration in participants with epilepsy (partial-onset seizures \[including secondarily generalized seizures\]) (age 4 years or older) or primary generalized tonic-clonic seizures (age 12 years or older).

Background: Most drugs that treat mood disorders take a long time to work. Ketamine works within hours. A dose can last for a week or more. Certain receptors in the brain might help ketamine work. A drug that blocks these receptors might affect how it works.
