Nortriptyline is a medication primarily used to treat depression, though it also has applications in the management of other conditions such as anxiety, chronic pain, and migraines. It belongs to a class of drugs know as tricyclic antidepressants (TCAs). Though newer classes of antidepressants, such as SSRIs (selective serotonin reuptake inhibitors) and SNRIs (serotonin-norepinephrine reuptake inhibitors), are more commonly prescribed today, nortriptyline remains an effective treatment option for many patients, particularly those who do not respond to other medications.

Nortriptyline works by increasing the levels of certain neurotransmitters in the brain, most notably serotonin and norepinephrine. These chemicals play a crucial role in regulating mood, pain, and overall mental well-be.
