Which anxiolytic medication is primarily prescribed for its non-benzodiazepine properties?

Buspar, also known as buspirone, is an anxiolytic medication that is primarily prescribed for its non-benzodiazepine properties. It works by affecting serotonin receptors in the brain and has a unique mechanism of action compared to benzodiazepines. Buspar is particularly useful for managing anxiety disorders and is often preferred in situations where dependence on medication is a concern since it generally has a lower risk of addiction and fewer sedative effects.

The other medications listed do not fit the criteria of being primarily non-benzodiazepines. Ativan, for instance, is a benzodiazepine that acts on the central nervous system to produce a calming effect. Elavil, or amitriptyline, is a tricyclic antidepressant with anxiolytic properties but is not classified as a primary anxiolytic. Wellbutrin, or bupropion, is an antidepressant used primarily for treating depression and for smoking cessation, rather than specifically for anxiety. Thus, Buspar is the correct answer, being distinctly categorized as an anxiolytic that does not fall under the benzodiazepine class.
