Which of the following is an example of an SSRI?

Selective Serotonin Reuptake Inhibitors (SSRIs) are a class of medications commonly used to treat depression and anxiety disorders by increasing the levels of serotonin in the brain. Among the choices given, Paxil is a well-known SSRI. It works by preventing the reabsorption (or reuptake) of serotonin, thereby increasing its availability in the synaptic cleft and enhancing mood and emotional balance.

Other choices include medications that belong to different classes. Elavil is an tricyclic antidepressant, Valium is a benzodiazepine used primarily for anxiety, and Klonopin is also a benzodiazepine used for seizure disorders and panic attacks. Understanding medication classifications is crucial for managing patient therapy effectively, as different classes have different mechanisms of action, side effects, and therapeutic uses. Thus, recognizing Paxil as an SSRI provides critical insights into its role in treating conditions like major depressive disorder and generalized anxiety disorder.
