Pharmacodynamics

Herbal preparation with sedative properties, which are caused by the fact that the medicine contains essential oil (about 0.2-2.8%), which is based on complex borneol ether, as well as acetate borneol with 3-methylbutanoic acid. In addition, the important active substances of drugs are such sexiterpens with monoterpenes: valeranone and β-karyophyllene, valerenal with pentanoic acid and valepotriates (0.05-0.67%) is a valtrate with isovalantrate.

Valepotriates leave such products of their own regression as valtroxal with baldrinil and homobaldrin. The drug enhances the sensitivity of GABA-conductors to the effect of aminalone, thereby increasing the strength of the slowing processes in the cerebral cortex. Along with this, there is an increase in the isolation and synthesis of GABA in the compounds of the brain neurons. Such an effect develops solely as a result of the influence of the sum of these substances, which are mixed in the valerian extract. It can not be reconstructed as a result of the isolated administration of valepotriates with essential oil or sexiterepens.

The sedative effect resulting from the use of drugs appears rather slowly, but at the same time it is very stable. It is fully developed only in the case of prolonged and systematic therapy. The reaction of the organism to any external pathogens is slowed down, and the process of natural retirement to sleep is simplified.

Valepotriates with pentanoic acid have spasmolytic properties, and in addition have a weak choleretic effect. In particular, it helps with spasm, as well as hyper-motor dysfunction of GWP. The complex of bioactive components of valerian extract according to neurohumoral mechanisms, and also due to influence on the PSS helps to regulate the work of the heart - to slow its rhythm and slightly expand the coronary vessels.
