| Description |
Doxepin is a psychotropic agent with antidepressant and anxiolytic properties.[T559] It is a tertiary amine that can be presented as (E) and (Z) stereoisomers with the (Z) stereoisomer corresponding to [cidoxepin]. Doxepin commonly produces a 5:1 (E):(Z) racemic mixture.[T83]
In a strict sense, doxepin is not a tricyclic antidepressant but it is commonly associated with the class since it shares a lot of properties with members of the drug family including [amitriptyline], [clomipramine], [desipramine], [imipramine], [nortriptyline], [protriptyline] and [trimipramine].[L5977]
Doxepin was developed by Pfizer and FDA approved in 1969 as an antidepressant.[L5971] However, in 2010 it was approved for the treatment of insomnia. The latter indication was presented by Pernix Therapeutics.[L5974] |
