Pharmacodynamics and pharmacokinetics
Valproic Acid improves the mental state of patients, has a sedative, central muscle relaxant and direct cardiotropic action. To this day, the mechanism of action of the drug is not fully understood. It is believed that the substance stimulates the work of the GABAergic system, inhibiting the enzyme GABA-transferase, which causes a decrease in the concentration of GABA in the nervous system. Also, the agent acts directly on the postsynaptic receptors (GABA-A receptor) that mimic or enhance the effect of the substance on the nervous system. In addition, the acid affects the operation of potential-dependent sodium channels, affects the activity of semi-impermeable membranes, and changes the conductivity of K. ions.
The substance after oral administration is completely and quickly absorbed in the digestive tract. Next, the agent dissociates to valproate ion and penetrates into the blood plasma. The degree of bioavailability is 93%. The degree of absorption does not depend on the intake of food. The maximum concentration of the drug in the blood reaches within 3 hours.
The equilibrium concentration of the drug will be observed on the 2nd-4th day of treatment. The substance has a sufficiently high degree of association with albumin blood – up to 95%. The medicine penetrates through the BBB, it is released during lactation. Metabolism occurs in the liver, where Valproic Acid is subjected to oxidation and glucuronization.
The medicine is withdrawn with the help of the kidneys. The half-life is between 8 and 20 hours. When combined with other drugs, if induction of metabolic enzymes is observed, the elimination half-life is reduced to 8 hours.
