What is the primary condition treated by Nortriptyline?

Nortriptyline is primarily prescribed to treat depression. It belongs to the class of medications known as tricyclic antidepressants, which are effective in elevating mood and alleviating symptoms associated with major depressive disorder. The mechanism by which nortriptyline functions involves the inhibition of the reuptake of neurotransmitters such as norepinephrine and serotonin in the brain, which helps improve mood and emotional balance.

While it can also be used off-label for conditions such as chronic pain and certain types of insomnia, its main use in clinical practice is centered around the treatment of depression. Regarding hypertension, nortriptyline is not indicated for this condition, as it can potentially raise blood pressure instead of lowering it.
