Clomipramine (trademarked as Anafranil) is a tricyclic antidepressant (TCA). It was developed in the early 1960s[2] by the Swiss drug manufacturer Geigy (now known as Novartis) and has been in clinical use worldwide ever since. It is the 3-chlorinated derivative of the earlier tricyclic, imipramine.
