tricyclic antidepressant drug
Noun: A tricyclic antidepressant drug is a class of medication used to treat clinical depression and certain other conditions. It works by increasing the levels of specific neurotransmitters (norepinephrine and serotonin) in the brain by blocking their reabsorption (reuptake) by nerve cells, thereby making more available to improve communication between brain cells and elevate mood.

They are typically considered when newer antidepressants are not suitable or effective. - Primary Use: Treating depression. - Secondary Uses: Sometimes used for chronic pain conditions, anxiety disorders, or insomnia, under medical supervision.
