Phenibut (beta-phenyl-gamma-aminobutyric acid or 4-amino-3-phenylbutyric acid) is a neuropsychotropic drug that was discovered and introduced into clinical practice in Russia in the 1960s. It has anxiolytic and nootropic (cognition enhancing) effects. It acts as a GABA-mimetic, primarily at GABA(B) receptors. Pharmacological activity of racemic phenibut relies on R-phenibut and this correlates to the binding affinity of enantiomers of phenibut to the GABAB receptor. In addition R-phenibut binds to the α2-δ subunit of voltage-dependent calcium channels. It is highly effective in treating anxiety, post-traumatic stress disorder, depression, asthenia, insomnia, alcoholism, stuttering, and vestibular disorders. It also improves mental performance (attention, memory, speed and accuracy of sensory-motor reactions), physical performance, reduces sleep disorders as well as movement and speech disorders.

Sample Use Guides
Initial dose is 250-500 mg (1-2 pills) 3 times a day. Maximum single dose: 750 mg, for patients over 60 years: 500 mg. The course of treatment is 2-3 weeks. If necessary, the course of treatment can be prolonged to 4-6 weeks. Patients, who have somnolence or other central nervous system disturbances during administration of Phenibut, should be careful about driving.
Route of Administration:
Oral
It has been established in experiments on the isolated spinal cord of 7-14-day-old rats that the GABAB-mimetic phenibut (10-100 uM) elicits a slow-developing depolarization of motoneurons, suppression of spontaneous activity and polysynaptic reflex discharges of motoneurons, recorded from the ventral roots.
