Pharmacological properties

Pharmacodynamics.

In animal pharmacology, sodium valproate has been shown to have anticonvulsant properties in various models of experimental epilepsy (with generalized and focal seizures).

Similarly, studies have shown that sodium valproate has an antiepileptic effect in various forms of epilepsy in humans. Presumably, this action is based on GABA-ergic (gamma-aminobutyric acid-mediated) activity, which prevents or limits the diffusion of discharges.

Some in vitro studies have shown that sodium valproate can stimulate HIV-1 replication, but this effect is weak and has not been reproducible in most studies. The clinical consequences of this effect in patients infected with HIV-1 are unknown. When using valproate sodium in patients infected with HIV-1, this information should be taken into account for the correct interpretation of the results of viral load analysis.

Pharmacokinetics.

Absorption. After oral administration of the drug Encorat Chrono, its bioavailability in blood plasma approaches 100%.

In blood plasma, the drug is in the form of valproic acid. Absorption of the drug Encorat Chrono, tablets, coated, prolonged action, in the gastrointestinal tract begins immediately and has a uniform and prolonged nature. This achieves the absence of peak plasma concentrations of the active substance and better maintenance of therapeutic concentrations of valproic acid over time.
