Which medication is used primarily to treat conditions associated with high uric acid levels?

Allopurinol is a medication specifically used to manage conditions related to elevated uric acid levels, such as gout and certain types of kidney stones. It functions as a xanthine oxidase inhibitor, reducing the production of uric acid in the body and thereby lowering serum uric acid levels. This helps prevent gout attacks and reduces the risk of uric acid crystal formation in joints and tissues.

In contrast, hydrochlorothiazide is a diuretic often used to treat high blood pressure and fluid retention but is not indicated for managing uric acid levels. Acetazolamide is a carbonic anhydrase inhibitor primarily used for the treatment of glaucoma and altitude sickness, also not relevant for hyperuricemia. Ciprofloxacin is an antibiotic used to treat bacterial infections and has no role in managing uric acid levels. Thus, allopurinol stands out as the appropriate choice for the management of conditions associated with high uric acid levels.
