Xanthine Oxidase inhibitors are a class of medication that treats gout. Gout is a form of arthritis that is caused by the buildup of uric acid from the breakdown of purines and proteins found in our diet and body. When uric acid is unable to leave the body, it becomes uric acid crystals that stick to sensitive tissues and joints causing pain, Xanthine inhibitors such as Allorpurinol, and works by blocking the xanthine oxidase enzyme, which is responsible for converting purines to uric acid. This reduces uric acid blood levels preventing the formation of uric acid crystals.
People taking allopurinol should notify their healthcare provider if they develop any rashes from taking the medication.
