Summary
Sulfinpyrazone can cause kidney failure, even in patients with existing renal issues. Monitor kidney function closely and stop sulfinpyrazone if blood urea nitrogen or creatinine levels rise.
Area of Science:
- Nephrology
- Pharmacology
Background:
- Sulfinpyrazone is a uricosuric agent used to treat gout.
- Renal complications associated with sulfinpyrazone are not well-documented.
Observation:
- Three patients developed acute renal failure shortly after initiating sulfinpyrazone therapy.
- One patient experienced reversible renal dysfunction, while another died from myocardial infarction.
Findings:
- The clinical presentation of renal failure was atypical.
- Elevated creatinine levels were noted in two patients prior to sulfinpyrazone administration.
- A third patient developed renal failure and subsequently died from myocardial infarction.
Implications:
- Close monitoring of renal function (blood urea nitrogen and creatinine) is recommended 2-4 days after starting sulfinpyrazone.
- Discontinuation of sulfinpyrazone is advised upon any indication of rising renal markers.
- Pre-existing renal impairment, even minor, should be considered a contraindication for sulfinpyrazone use.
