Generic Name: Alprazolam



Xanax (alprazolam) is an anxiolytic (antipanic and antianxiety) benzodiazepine medication classified as a schedule IV controlled substance by the U.S. Drug Enforcement Administration (DEA). According to the DEA, a schedule IV drug has a low potential for abuse and a low risk for dependence. Alprazolam does have the potential for misuse, although some experts claim that the risk is low and similar to that of other benzodiazepine drugs.

This drug possesses antianxiety, sedative, muscle relaxing, and anticonvulsant properties. It slows down the chemical movement within the central nervous system, which results in the reduction of anxiety.

History of Xanax

Dr. Leo Sternbach is credited with the discovery benzodiazepines. Alprazolam was first released by Upjohn Laboratories (now a part of Pfizer) in 1981, as the first approved drug for panic attacks. Within two years, it became a “blockbuster” drug in the United States. Now, this medication is the most prescribed benzodiazepine in America.
