Antigout agents are medications used to treat the symptoms of gout, a common form of arthritis. There are several synonyms for antigout agents, including uricosurics, uric acid lowering drugs, anti-hyperuricemics, and xanthine oxidase inhibitors. Uricosurics are a type of antigout agent that increase the excretion of uric acid by the kidneys, while xanthine oxidase inhibitors block the production of uric acid in the body. Anti-hyperuricemics are a general term for drugs that lower elevated uric acid levels in the blood. Regardless of the term used, antigout agents are an important tool in managing the painful symptoms of gout.
