Sulfinpyrazone is a uricosuric medication used to treat gout.

Uricosuric medications (drugs) are substances that increase the excretion of uric acid in the urine, thus reducing the concentration of uric acid in blood plasma.

Uricosuric medications are typically preferred if undersecretion of uric acid, as indicated by a 24-hour collection of urine results in a uric acid amount of less than 800 mg, is found.

To help reduce the number and severity of gout attacks that can result when uric acid levels change suddenly, colchicine may be given at the same time as uricosuric medications, such as probenecid or sulfinpyrazone, which lower uric acid levels, or xanthine oxidase inhibitors, which block uric acid production.
