Protriptyline (Vivactil) is a tricyclic antidepressant (TCA), specifically a secondary amine, indicated for the treatment of depression and ADHD. Unique among the TCAs, protriptyline tends to be energizing instead of sedating, and is sometimes used for narcolepsy to achieve a wakefulness-promoting effect.
