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 history of uric acid kidney stones.[1]

Research

Trial have found that, Sulfinpyrazone taken in specific daily dose immediately following a patient having suffered from a myocardial infarction seem to drastically reduce the incidence of sudden death by as much as 43% and cardiac mortality by 32% in the 24 months following their heart attack. [2]
