This drug was invented in the 70s of the last century in the Soviet Union. It quickly became popular, not only within the country, but also abroad. It was a real pride of pharmacists, it was recommended even for astronauts. Soviet scientists had no idea that their descendants would become “cosmonauts” of a different category.
Phenibut is a derivative of γ-aminobutyric acid, a central nervous system depressant with a tranquilizing effect.
The chemical structure of the active substance of this drug is similar to GABA - gamma-aminobutyric acid - the main inhibitory neurotransmitter in the human brain. That is, phenibut is inherently a synthetic form of GABA. It has a short half-life and elimination from the body, and effects last from 15 to 24 hours.
Initially, phenibut was intended to combat anxiety, sleep disturbance, neuroses, vestibular disorders, stuttering, nervous tics and alcohol withdrawal syndrome. Then it began to be prescribed as a nootropic that can improve memory and attention, mood and well-being. It increased physical endurance and resistance to stress factors.
However, in developed countries, where the requirements for drugs are high, now it is perceived more as a food supplement - dietary supplement.
To date, phenibut is registered as a drug only in the post-Soviet space.
The expected effectiveness has not yet been proven, in some scientific communities it is referred to as a placebo. For example, in Australia they even call for a ban on this substance, citing the unsafety of overdose and withdrawal syndrome.
