Treating Lennox-Gastaut syndrome in epileptic pediatric patients with third-generation rufinamide

Mechanism of NLRP3 Inflammasome in Epilepsy and Related Therapeutic Agents

Epilepsy is one of the most widespread and complex diseases in the central nervous system (CNS), affecting approximately 65 million people globally, an important factor resulting in neurological disability-adjusted life year (DALY) and progressive cognitive dysfunction. Medication is the most essential treatment. The currently used drugs have shown drug resistance in some patients and only control symptoms; the development of novel and more efficacious pharmacotherapy is imminent. Increasing evidence suggests neuroinflammation is involved in the occurrence and development of epilepsy, and high expression of NLRP3 inflammasome has been observed in the temporal lobe epilepsy (TLE) brain tissue of patients and animal models. The inflammasome is a crucial cause of neuroinflammation by activating IL-1β and IL-18. Many preclinical studies have confirmed that regulating NLRP3 inflammasome pathway can prevent the development of epilepsy, reduce the severity of epilepsy, and play a neuroprotective role. Therefore, regulating NLRP3 inflammasome could be a potential target for epilepsy treatment. In summary, this review describes the priming and activation of inflammasome and its biological function in the progression of epilepsy. In addition, we reviewes the current pharmacological researches for epilepsy based on the regulation of NLRP3 inflammasome, aiming to provide a basis and reference for developing novel antiepileptic drugs.

An overview of third-generation antiseizure drugs: Clobazam, lacosamide, rufinamide, and vigabatrin

Four antiseizure drugs have been approved in the United States since 2008. Clobazam, a 1,5-benzodiazepine, was approved in October 2011 as an adjunctive therapy for Lennox-Gastaut syndrome (LGS) in patients 2 years and older. Lacosamide, an amino acid that selectively enhances the slow inactivation of voltage-gated sodium channels, was approved in October 2008 as an add-on therapy for partial onset seizures in patients 17 years and older. Rufinamide, a triazole derivative, was approved in November 2008 as an adjunctive therapy for LGS in patients 4 years and older. Vigabatrin, an irreversible inhibitor of GABA transaminase, was approved in August 2009 for the treatment of infantile spasms in children ages 1 month to 2 years and intractable complex partial seizures in adults.
