Mechanism of action

Valparin XP is an anticonvulsant drug. Sodium valproate increases the content of gamma aminobutyric acid (GABA) in the brain, which accordingly increases the content of GABA in postsynaptic neurons. In addition, sodium valproate affects the transfer of potassium ions through the membranes of neurons. As a result, the development and spread of epileptic excitation along neurons are suppressed.
Sodium valproate has anticonvulsant activity in various types of epilepsy in humans. Valparin XP does not have a pronounced hypnotic and sedative effects, and also has no inhibitory effect on the respiratory center.Sodium valproate does not have a negative effect on blood pressure, heart rate, kidney function and body temperature.

Drug Interactions
