Imagabalin (INN, USAN; PD-332,334) is a drug which acts as a ligand for the α2δ subunit of the voltage-dependent calcium channel,[1] with some selectivity for the α2δ1 subunit over α2δ2.[2] Under development by Pfizer as a pharmaceutical medication, it has demonstrated preclinical efficacy of anxiolytic, analgesic, hypnotic, and anticonvulsant-like activity and is currently in phase III clinical trials for the treatment of generalized anxiety disorder.[2][3]
