Itis primarily used to treat gout, a type of arthritis caused by excess uric acid in the blood leading to painful joint inflammation. It works by inhibiting xanthine oxidase, an enzyme involved in the production of uric acid, thereby reducing its levels in the blood. This helps to prevent gout attacks, decrease the formation of uric acid crystals, and protect the joints and kidneys from damage. It is particularly beneficial for patients who are intolerant to or have contraindications for other gout medications, such as allopurinol. It should be taken under medical supervision, with regular monitoring of uric acid levels and kidney function to ensure safe and effective treatment.
