Moodnor 10 mg is a tricyclic antidepressant (TCA) containing Nortriptyline Hydrochloride. It is primarily used to treat major depressive disorder (MDD), neuropathic pain, and certain anxiety-related conditions. Nortriptyline works by increasing the levels of neurotransmitters, such as serotonin and norepinephrine, in the brain, which helps improve mood and alleviate pain sensations.
