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. This helps to reduce the level of pain you experience, which can enable you to get back to your daily activities and have a better quality of life.
How do antidepressants relieve pain?
Antidepressants may increase neurotransmitters in the spinal cord that reduce pain signals. But they don’t work immediately. You may feel some relief from an antidepressant after a week or so, but maximum relief may take several weeks. People generally experience moderate pain relief from antidepressants.
How do tricyclics work?
Tricyclic antidepressants work by preventing the reabsorption of neurotransmitters called serotonin and norepinephrine. The body needs both of these to function normally. If there is too much of either, you may end up experiencing anxiety. If there is not enough, depression may ensue.
Why do doctors prescribe antidepressants for pain?

Does amitriptyline repair nerve damage?
Amitriptyline is a tricyclic antidepressant that is widely used to treat chronic neuropathic pain (pain due to nerve damage). It is recommended as a first line treatment in many guidelines. Neuropathic pain can be treated with antidepressant drugs in doses below those at which the drugs act as antidepressants.
How does nortriptyline work for nerve pain?
How does nortriptyline work? Nortriptyline works by increasing the amount of specific nerve transmitters in the nervous system, reducing pain messages arriving in the brain.
How does doxepin help nerve pain?
These antidepressants inhibit the reuptake of serotonin and norepinephrine at the synapse, but do so differentially according to chemical structure. The tertiary amines (e.g., amitriptyline, doxepin, imipramine) inhibit serotonin to a greater degree than norepinephrine.
Do antidepressants help with nerve pain?
Even though a type of antidepressant called tricyclic antidepressants (TCAs) were not originally designed to be painkillers, there’s evidence to suggest they’re effective in treating long-term (chronic) nerve pain in some people.

Is there a medication that treats both depression and pain?

What is the best tablet for nerve pain?
The main medicines recommended for neuropathic pain include:
- amitriptyline – also used for treatment of headaches and depression.
- duloxetine – also used for treatment of bladder problems and depression.
- pregabalin and gabapentin – also used to treat epilepsy, headaches or anxiety.
Does serotonin reduce pain?
It is likely that serotonin both inhibits and promotes pain perception by different physiological mechanisms, in contrast to norepinephrine which is predominately inhibitory. Additional evidence of the role of monoamines in pain modulation comes from studies of antidepressant administration in animal models of pain.
