Karen,
Thank you for your question.
Xanax (alprazolam) is a short-acting benzodiazepine, commonly used to treat anxiety. Buspar (buspirone) belongs to a different class of medications (azaspirodecanediones), but it is also used to treat anxiety. In addition, Buspar can be used to treat depression. You can find more information about Xanax here and Buspar here.
Best of luck,
Casey
