Protriptilina (brand name, Vivactil) is a tricyclic antidepressant of the dibenzocycloheptene family of medications. It is used to treat moderate to severe depression in adults, as well as major depressive disorder and nocturnal enuresis, a bed-wetting problem that is most common in children but can sometimes occur in adults.
