Which of the following benzodiazepines is NOT typically used for anxiety?

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) that is primarily used as an antidepressant and for the treatment of various anxiety disorders, such as generalized anxiety disorder and panic disorder. However, it is not classified as a benzodiazepine, which is the key distinction in this question.

The other options—Chlordiazepoxide, Clorazepate dipotassium, and Diazepam—are all benzodiazepines commonly prescribed for anxiety due to their anxiolytic properties. These medications work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA-A receptor, leading to increased inhibitory neurotransmission and resulting in a calming effect that is beneficial for anxiety symptoms.

In summary, while fluoxetine is effective for treating anxiety, it does not fall under the category of benzodiazepines, making it the correct choice for this question.
