Description

Phenibut Pharmacodynamics
As a derivative of gamma-aminobutyric acid and phenylethyl amine, aminophenyl butyric acid facilitates GABAergic transmission of nerve impulses in the central nervous system (direct effect on GABA-ergic receptors). It has tranquilizing effect that is combined with stimulation of central nervous system activity; it improves functional condition of the brain by normalizing its metabolism and blood flow in the brain (it increases volume and linear velocity of blood flow, reduces vascular resistance and improves microcirculation), reduces vasovagal symptoms (including headache and “heavy” feeling in the head, sleep disorders, irritability, emotional lability), eliminates psychoemotional tension, contributes to the development of the brain, and improves the blood circulation. Does not affect choline and adrenoreceptors. It prolongs the latent period and shortens the duration and severity of nystagmus. With a course of treatment increases physical and mental performance (improves attention, memory, speed and accuracy of sensory-motor reactions). It reduces manifestations of asthenia, increases interest and initiative (promotes motivation for activity) without the effects of sedation or agitation,
Does not cause central nervous system depression in the elderly, muscle relaxant aftereffects are mostly absent.
It reduces the depressing effect of ethanol on the central nervous system.
