Abstract

The invention relates to a composition containing r-aminobutyric acid and antiepileptic drugs selected from gabapentin, oxcarbazepine, valproic acid, topiramate, phenytoin and the like, and relates to purposes thereof in the aspects of preventing, delaying or treating the epileptic seizure, in particular resisting epilepsia, scavenging free radicals and restraining lipid peroxidation in the epileptic seizure.

Description

technical field [0001] The present invention relates to a combination comprising r-aminobutyric acid and antiepileptic drugs selected from gabapentin, oxcarbazepine, valproic acid, topiramate and phenytoin, and its role in the prevention, delay of progression or treatment of epileptic seizures, especially in epileptic seizures Anti-epileptic and anti-lipid peroxidation in seizures. Background technique [0002] The pathogenesis of epilepsy is very complex and has not yet been fully elucidated. In the 1980s, beginners proposed three major pathogenic factors of epilepsy: 1) genetic predisposition; 2) epileptic pathological changes in the brain; 3) precipitating factors, such as biochemical (excitatory, inhibitory amino acids) or immunological aspects changes etc. The treatment of epilepsy is mainly to control epileptic seizures through drugs. The antiepileptic activity of drugs is achieved by acting on one or more targets in brain tissue, including ion channels, neurotransmi...
