Anticonvulsant/antiepileptic carbonic anhydrase inhibitors: a patent review

Introduction: An epileptic seizure is a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain. The International League Against Epilepsy classifies seizures in two broad categories: partial (localized to one cerebral hemisphere) and generalized (localized to both cerebral hemispheres). One indirect pathway for the treatment of epilepsy includes the inhibition of carbonic anhydrase (CA), thereby increasing CO2 levels in the brain.
