FBX 80 Tablet contains Febuxostat 80mg, a potent xanthine oxidase inhibitor used primarily to manage chronic gout and hyperuricemia by reducing serum uric acid levels. Febuxostat works by selectively inhibiting the enzyme xanthine oxidase, which is responsible for converting hypoxanthine to xanthine and xanthine to uric acid, thereby decreasing uric acid production in the body. This reduction helps prevent gout attacks, tophi formation, and kidney stone development associated with elevated uric acid. FBX 80 is typically prescribed for patients who are intolerant to or inadequately controlled by other urate-lowering therapies such as allopurinol. It is important to take FBX 80 exactly as directed by a healthcare professional, usually once daily, with or without food. Patients should maintain adequate hydration to minimize the risk of kidney stones and monitor liver function periodically due to potential hepatotoxicity. Common side effects may include rash, nausea, joint pain, and liver enzyme abnormalities. FBX 80 is contraindicated in patients with severe liver impairment and should be used cautiously in those with cardiovascular disease. Always consult a healthcare provider before starting or discontinuing this medication to ensure safe and effective treatment.
