How do tricyclics help pain?

Tricyclic antidepressants may relieve neuropathic pain by their unique ability to inhibit presynaptic reuptake of the biogenic amines serotonin and noradrenaline, but other mechanisms such as N-methyl-D-aspartate receptor and ion channel blockade probably also play a role in their pain-relieving effect.

How does amitriptyline relieve pain?

It works on two chemicals, noradrenaline and serotonin, that are found in nerves. When amitriptyline is used to treat nerve pain, it lowers the pain signals to the brain.
