Anticonvulsant effect is the property of the substances that weaken or strengthen the progress of excitation of inhibitory processes in the CNS, including barbiturates, bromides, tranquilizers, and other various groups.
However, a number of means allocate specific anticonvulsant activity and efficacy in pathological conditions involving convulsive reactions (with intoxication, infectious diseases, CNS trauma, etc.). The special value belongs to anticonvulsants that are effective in epilepsy and used to prevent or treat seizures or their respective equivalents (loss or impairment of consciousness, behavioral and autonomic disorders, etc.) of certain forms of the disease.
Anticonvulsant (antiepileptic) drugs are synthetic compounds of different chemical groups: derivatives of barbituric acid (phenobarbital, benzonal, benzobamil, hexamidine) hydantoin derivatives (phenytoin), oksazolidindiona (Trimethadione), succinimides (ethosuximide, pufemid) derivatives iminostilbena (carbamazepine) etc. More recently benzodiazepine drugs have been developed. They have especially pronounced anticonvulsant effect (clonazepam, etc.). There has been a brand new group of antiepileptic drugs - valproic acid and its salts (or Atsediprol konvuleks, etc.).
