Chemical structure of pregabalin, gabapentin, and GABA

Gabapentinoids are a class of drugs that are derivatives of the inhibitory neurotransmitter γ-aminobutyric acid (GABA) which block α2δ subunit-containing voltage-dependent calcium channels.[1][2] This site has been referred to as the gabapentin receptor (α2δ subunit), as it is the target of the drugs gabapentin and pregabalin.[3] Clinically-used gabapentinoids include gabapentin (Neurontin) and pregabalin (Lyrica)[1][2][4] as well as a gabapentin prodrug, gabapentin enacarbil (Horizant).[5] Another analogue mirogabalin is in clinical trials but has not yet been approved.[6] Other compounds from this family used in research but not developed for medical use include phenibut (Noofen), atagabalin, 4-methylpregabalin and PD-217,014.

Gabapentinoids are used clinically in the treatment of conditions including epilepsy, neuropathic pain, fibromyalgia, generalized anxiety disorder, and restless legs syndrome.[1][5][7] Some off-label uses include migraine, social phobia, panic disorder, mania, bipolar disorder, and alcohol withdrawal.[5][8]
