What is sulfinpyrazone?

Sulfinpyrazone is no longer available in the United States.

Sulfinpyrazone is a medication primarily used to treat gout. It prevents the occurrence of acute attacks of gout by lowering the levels of uric acid in the body. It lowers these levels by increasing the excretion of uric acid in the kidneys. Sulfinpyrazone has no effect on the acute attacks once they begin. In   addition to gout, it is sometimes used to prevent or treat other conditions with excessively high uric acid levels in the body.

Sulfinpyrazone is classified as a uricosuric or anti-gout medication. Recently the brand name version, Anturane, and all generic versions approved for use in the United States (US) were discontinued by the manufacturers. The reason for this is not known, but the US Food and Drug Administration has stated that it was not for safety or efficacy reasons. Before it was discontinued, sulfinpyrazone was available only by prescription, and it was supplied as either a capsule or tablet. It is still produced in other countries.
