Description: Imagabalin, also known as PD0332334 and PF-00195889, is a drug which acts as a ligand for the α2δ subunit of the voltage-dependent calcium channel, with some selectivity for the α2δ1 subunit over α2δ2. Imagabalin 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.
