Multiple Choice

Which of the following is an SSRI?

SSRI stands for selective serotonin reuptake inhibitor—these medications work by blocking the reabsorption of serotonin into the presynaptic neuron, increasing serotonin availability in the synapse. Prozac is fluoxetine, a well-known SSRI, so it fits this mechanism. The other drugs shown belong to different drug classes: Cylert (pemoline) is a stimulant used for ADHD, Ritalin (methylphenidate) is another stimulant, and Valium (diazepam) is a benzodiazepine. They do not act as serotonin reuptake inhibitors, so they are not SSRIs.
