Hyperuricemia and Gout: The Role of Losartan
1St. John's University College of Pharmacy and Health Sciences, Queens, New York.
Insights
Losartan, an angiotensin II receptor blocker, uniquely reduces uric acid levels. Clinical guidelines now recommend it for hypertensive patients with gout due to its uricosuric properties.
Area of Science:
- Nephrology
- Cardiology
- Rheumatology
Background:
- Hypertension management often involves medications that can affect uric acid levels.
- Elevated uric acid is a risk factor for gout and kidney disease.
- Angiotensin II receptor blockers (ARBs) are a class of antihypertensive drugs.
Purpose of the Study:
- To highlight the unique uricosuric effect of losartan.
- To support the use of losartan in hypertensive patients with gout.
Main Methods:
- Review of clinical guidelines and pharmacological data.
- Analysis of losartan's mechanism of action on uric acid excretion.
Main Results:
- Losartan is the sole ARB demonstrated to significantly decrease serum uric acid.
- Its uricosuric effect is a recognized clinical benefit.
Conclusions:
- Losartan offers a dual benefit for hypertensive patients with gout by controlling blood pressure and lowering uric acid.
- Clinical practice guidelines recommend losartan for this patient population owing to its uricosuric properties.
Abstract:
Losartan is the only angiotensin II receptor blocker that has shown to significantly lower uric acid levels. The addition of or switch to losartan as an antihypertensive agent for patients with gout is recommended by clinical guidelines because of its benefit as a uricosuric agent.
