Alprazolam, commonly known by its brand name Xanax, is a medication belonging to the benzodiazepine class. It is primarily prescribed for the treatment of anxiety and panic disorders. Alprazolam works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid in the brain, which helps to reduce excessive neuronal activity and promote a sense of calmness and relaxation. Alprazolam is available in various forms, including immediate-release tablets, extended-release tablets, and oral solutions. The dosage and frequency of administration are determined by a healthcare professional based on the individual's specific needs and response to treatment.
