Pharmacological properties

It is an antiepileptic medication. It has an anti-manic, normotimic (normalizing mood) effect. The active substance activates the inhibitory GABAergic system in the brain. It also blocks voltage-dependent Na-channels of the membranes of nerve cells, which leads to the stabilization of their function, reduces the activity of neurotransmitter acids (aspartate, glutamate), interacts with brain adenosine receptors. Increases the seizure threshold, corrects epileptic personality changes.
