Sulfinpyrazone is a uricosuric medication used to treat gout. It also sometimes is used to reduce platelet aggregation by inhibiting degranulation of platelets which reduces the release of ADP and thromboxane.

Like other uricosurics, sulfinpyrazone works by competitively inhibiting uric acid reabsorption in the proximal tubule of the kidney.

Contraindications

Sulfinpyrazone must not be used in persons with renal impairment or a high rate of excretion of uric acid (hyperuricosuria).^[1]
