phenibutとは 意味・読み方・使い方

β-Phenyl-γ-aminobutyric acid, better known as phenibut or less commonly fenibut or phenybut, is a derivative of the naturally occurring inhibitory neurotransmitter γ-aminobutyric acid (GABA). The addition of a phenyl ring allows phenibut to cross the blood brain barrier. Phenibut is sold as a dietary supplement in the United States, while in Russia it is sold as a neuropsychotropic drug. It has been reported by some to possess nootropic actions for its ability to improve neurological functions, however other researchers had not previously observed these effects. However, it is generally accepted that phenibut has anxiolytic effects in both animal models and in humans. Phenibut was discovered in the Soviet Union in the 1960s, and has since been used there to treat a wide range of ailments including post-traumatic stress disorder, anxiety, and insomnia.
