Viqualine (INN) (developmental code name PK-5078) is an antidepressant and anxiolytic drug that was never marketed.[1][2][3] It acts as a potent and selective serotonin releasing agent and serotonin reuptake inhibitor.[3][4] In addition, viqualine displaces diazepam from the GABAA receptor and produces benzodiazepine-like effects, indicating that it is also a positive allosteric modulator of the benzodiazepine site of the GABAA receptor.[3][5] The drug has mainly been researched as a potential treatment for alcoholism.[6][7]
