Research and development of 2-ethyl-6-methyl-3-oxypyridine succinate nano-form for the treatment of epilepsy

Abstract

The aim is to develop an antiepileptic drug based on polymer nanoparticles with 2-ethyl-6-methyl-3-oxypyridine succinate to facilitate the drug transport through the blood-brain barrier. Materials and methods. The nano-drug was created using the biologically active substance 2-ethyl-6-methyl-3-hydroxypyridine succinate and polybutyl cyanoacrylate (PBCA) nanoparticles. The advantages of this nano-form over the active ingredient of the same drug were studied using experimental models: the maximum electroshock test (MES), the antagonism test with corazol, models with a cobaltinduced epileptic focus and secondary generalized convulsions, and models of status epilepticus. Results. The antiseizure effects of the nanoform on the experimental models of epilepsy are identified. Conclusion. The nano-drug reduces the number of secondary generalized clonic-tonic seizures by 7.8 times; it also reduces 10-fold the animal mortality and diminishes the seizure manifestations that occur in the interictal period of the epileptic status.
