ATC Group: N06AA09 Amitriptyline
Anatomical Therapeutic Chemical Classification System
Amitriptyline is a tricyclic antidepressant and an analgesic. It prevents the re-uptake, and hence the inactivation of noradrenaline and serotonin at nerve terminals. Reuptake prevention of these monoamine neurotransmitters potentiate their action in the brain. This appears to be associated with the antidepressant activity.
