Clonazepam is a classical medicine from the group of benzodiazepines which has a broad-spectrum action. Clonazepam has more intense antiepileptic effect which occurs by means of the specific influence on the receptors of the central nervous system. Clonazepam provides a myorelaxing, anticonvulsant, and sedative action. It slows down a transfer of the nerve impulses through the central nervous system, so that the intensity of the convulsive attacks is reduced. The amount of the epileptic attacks is reduced by 2 times in patients taking Clonazepam. Clonazepam has been approved by FDA and is considered one of the best drugs for the treatment of epilepsy in adults and children, including newborns.
