Pipofezine (Azafen or Azaphen) is a tricyclic antidepressant (TCA) approved in Russia for the treatment of depression. It was introduced in the late 1960s and is still used today. Pipofezine has been shown to act as a potent inhibitor of the reuptake of serotonin. In addition to its antidepressant action, pipofezine has sedative effects as well, suggesting antihistamine activity. Other properties such as anticholinergic or antiadrenergic actions are less clear but are likely. The main advantage of Azafen compared with other tricyclic antidepressants is that this drug has a low toxic effect on the body, including the heart, and it does not block cholinergic receptors and does not change the activity of monoamine oxidase. The maximum concentration in the blood is reached after 1-2 hours after taking the drug. Absorbed in the gastrointestinal tract, metabolism occurs in the liver, and is excreted by Azaphene kidneys.
