Interactions

Phenibut (contracted from β-phenyl-γ-aminobutyric acid), is a CNS depressant with anxiolytic and sedative properties. Phenibut is a derivative of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). It is one of the few drugs recognized to act as an agonist primarily towards GABA_B receptors rather than GABA_A.
