Aminobutyric acid
Gabapentinoids, also known as α2δ ligands, are a class of drugs that are derivatives of the inhibitory neurotransmitter gamma-Aminobutyric acid (GABA) (i.e., GABA analogues) which block α2δ subunit-containing voltage-dependent calcium channels (VDCCs). This site has been referred to as the "gabapentin receptor" (α2δ subunit), as it is the target of the drugs gabapentin and pregabalin.
