Alprazolam, also known under the trade names Xanax (not to be confused with Zantac), Xanor, Alprax, and Niravam, is a short-acting drug of the benzodiazepine class. It is primarily used to treat moderate to severe anxiety disorders and panic attacks, and is used as an adjunctive treatment for anxiety associated with moderate depression. It is also available in an extended-release form, Xanax XR, both of which are now available in generic form. Alprazolam possesses anxiolytic, sedative, hypnotic, anticonvulsant, and muscle relaxant properties.
