Protriptyline, sold under the brand name Vivactil among others, is a tricyclic antidepressant (TCA), specifically a secondary amine. Uniquely among most of the TCAs, protriptyline tends to be energizing instead of sedating, and is sometimes used for narcolepsy to achieve a wakefulness-promoting effect.
