Phenibut, sold under the brand names Anvifen, Fenibut, and Noofen among others, is a central nervous system depressant with anxiolytic and stimulant effects which is used in the treatment of anxiety, insomnia, and for a variety of other indications. It is usually taken by mouth as a tablet, but can also be given as an intravenous infusion.
Side effects of phenibut include sedation, sleepiness, nausea, irritability, agitation, dizziness, and headache, among others. Overdose of phenibut can produce marked central nervous system depression including unconsciousness, although no deaths have been reported. The medication is structurally related to the neurotransmitter γ-aminobutyric acid (GABA), and hence is a GABA analogue. Phenibut is thought to act as a GABAB receptor agonist, similarly to baclofen and γ-hydroxybutyrate (GHB). However, at low concentrations, phenibut mildly increases the concentration of dopamine in the brain, providing stimulatory effects in addition to the anxiolysis. Subsequent research has found that it is also a potent blocker of α2δ subunit-containing voltage-dependent calcium channels (VDCCs), similarly to gabapentinoids like gabapentin and pregabalin.
Recreational use:
Phenibut is used recreationally due to its ability to produce euphoria, anxiolysis, and increased sociability. Because of its delayed onset of effects, first-time users often mistakenly take an additional dose of phenibut in the belief that the initial dose did not work. Recreational users usually take the drug orally; there are a few case reports of rectal administration and one report of insufflation, which was described as "very painful" and causing swollen nostrils.
