Which medication is classified as an antidepressant?

Pamelor is classified as an antidepressant because it is the brand name for nortriptyline, which belongs to a group of medications known as tricyclic antidepressants. These drugs work by increasing the levels of certain neurotransmitters in the brain, such as serotonin and norepinephrine, which are believed to be linked to mood regulation. By enhancing these neurotransmitter levels, antidepressants like Pamelor can help alleviate symptoms of depression and improve overall mood.

The other medications mentioned serve different therapeutic purposes. For example, Hytrin is primarily used to treat high blood pressure and benign prostatic hyperplasia, Evista is a selective estrogen receptor modulator used for osteoporosis and breast cancer prevention, and Bystolic is a beta-blocker used to manage hypertension and certain heart conditions. These medications do not affect mood in the way antidepressants do, thus distinguishing Pamelor as the correct choice.
