Imipramine (sold as Antideprin®, Janimine®, Tofranil®) is an antidepressant medication, a tricyclic antidepressant of the dibenzazepine group, mainly used in the treatment of clinical depression and enuresis.
Imipramine was, in the late 1950s, the first tricyclic antidepressant to be developed (by Ciba-Geigy). Initially, it was tried against psychotic disorders (e.g. schizophrenia), but proved insufficient. During the clinical studies its antidepressant qualities, unsurpassed until today, became evident. Subsequently it was extensively used as standard antidepressant and later served as a prototypical drug for the development of the later released tricyclics. It is not as commonly used today but sometimes used to treat major depression as a second-line treatment. It has also seen limited use in the treatment of migraines, ADD and post concussive syndrome. Imipramine has additional indications for the treatment of panic attacks and chronic pain. In pediatric patients it is relatively frequently used to treat pavor nocturnus and nocturnal enuresis.
