'''Gabapentinoids''', also known as α<sub>2</sub>δ ligands, are a relatively small chemical class of [[psychoactive substances]] derived from [[GABA|gamma-aminobutyric acid]] (GABA).{{citation needed}} Members of this class include [[gabapentin]], [[F-phenibut]], [[phenibut]] and [[pregabalin]]. | '''Gabapentinoids''', also known as α<sub>2</sub>δ ligands, are a relatively small chemical class of [[psychoactive substances]] derived from [[GABA|gamma-aminobutyric acid]] (GABA).{{citation needed}} Members of this class include [[gabapentin]], [[F-phenibut]], [[phenibut]] and [[pregabalin]]. | ||

Gabapentin, pregabalin, and phenibut all undergo little or no metabolism. Conversely, gabapentin enacarbil, which acts as a prodrug of gabapentin, must undergo enzymatic hydrolysis to become active. This is done via non-specific esterases in the intestines and to a lesser extent in the liver.<ref name=":1" /> | Gabapentin, pregabalin, and phenibut all undergo little or no metabolism.
