Because gout is caused by uric acid in the blood, medicine that controls gout either reduces the uric acid that the body produces or increases the amount that the body releases, according to Mayo Clinic. Anti-inflammatory drugs are used to treat the pain of gout.
Febuxostat and Allopurinol are xanthine oxidase inhibitors, medications that lower the amount of produced uric acid, as Mayo Clinic explains. Probenecid increases the kidneys' ability to take uric acid and release it from the body through urine. Nonsteroidal anti-inflammatory drugs are primarily used for attacks of gout, but at lower doses, they can be used to prevent future attacks.
