Which medication classification does fluoxetine belong to?

Fluoxetine is classified as a selective serotonin reuptake inhibitor (SSRI). This class of medications works by increasing the levels of serotonin in the brain, which is a neurotransmitter that plays a key role in mood regulation. SSRIs are commonly used to treat depression, anxiety disorders, obsessive-compulsive disorder, and other mental health conditions. Fluoxetine specifically targets the serotonin transporter, inhibiting the reuptake of serotonin into the presynaptic neuron, thus enhancing serotonergic transmission and alleviating symptoms of depression and anxiety.

This classification is significant because SSRIs are often preferred in clinical settings due to their relatively favorable side effect profile compared to older classes of antidepressants. The other medication classifications listed—such as benzodiazepines, typical antipsychotics, and tricyclic antidepressants—serve different therapeutic purposes and mechanisms of action, which is why they do not apply in this case.
