What is the primary purpose of tricyclic medications?

The primary purpose of tricyclic medications is to treat depression. These medications are a class of antidepressants that work by altering the levels of neurotransmitters in the brain, primarily serotonin and norepinephrine. By increasing the availability of these neurotransmitters, tricyclics can help alleviate symptoms of depression and are often effective for individuals who may not respond well to other types of antidepressants.

Tricyclic medications are also used for other conditions such as anxiety disorders, chronic pain management, and insomnia, but their main and most recognized application in clinical practice is for the treatment of depressive disorders. This effectiveness in improving mood and energy levels is why tricyclics are a key option in psychiatric treatment.
