Captodiame (INN), also known as captodiamine, is an antihistamine sold under the trade names Covatine, Covatix, and Suvren which is used as a sedative and anxiolytic. The structure is related to diphenhydramine.[2]

A 2004 study suggested captodiame may be helpful in preventing benzodiazepine withdrawal syndrome in people discontinuing benzodiazepine treatment.[2]

In addition to its actions as an antihistamine, captodiamine has been found to act as a 5-HT2C receptor antagonist and σ1 receptor and D3 receptor agonist.[3] It produces antidepressant-like effects in rats.[3] However, captodiamine is unique among antidepressant-like drugs in that it increases brain-derived neurotrophic factor (BDNF) levels in the hypothalamus but not in the frontal cortex or hippocampus.[3] This unique action may be related to its ability to attenuate stress-induced anhedonia and corticotropin-releasing factor (CRF) signaling in the hypothalamus.[3]
