Which of the following is NOT an antidepressant?

The medication that is not classified as an antidepressant is Augmentin. Augmentin is a combination antibiotic that contains amoxicillin and clavulanate potassium, used primarily to treat bacterial infections. It works by inhibiting the growth of bacteria, rather than affecting mood or emotional well-being, which is the primary function of antidepressants.

In contrast, Lexapro, Cymbalta, and Paxil are all established antidepressant medications. Lexapro (escitalopram) is a selective serotonin reuptake inhibitor (SSRI) commonly used to treat depression and anxiety disorders. Cymbalta (duloxetine) is a serotonin-norepinephrine reuptake inhibitor (SNRI) that is effective for both depression and certain types of chronic pain. Paxil (paroxetine) is also an SSRI, prescribed for depression as well as anxiety and other mood disorders.

Understanding the classification and purpose of medications is crucial in pharmacy practice, as it helps ensure that patients receive appropriate treatment for their conditions.
