Fostat

Febuxostat is recommended at 40 mg or 80 mg once daily. The recommended starting dose of Febuxostat is 40 mg once daily. For patients who do not achieve a serum uric acid less than 6 mg /dL after 2 weeks with 40 mg, Febuxostat 80 mg is recommended. Febuxostat can be administered without regard to food or antacid use. No dose adjustment is necessary when administering Febuxostat to patients with mild to moderate renal or hepatic impairment.

The most common adverse events associated with the use of Febuxostat may include liver function abnormalities, nausea, arthralgia, and rash.

Febustat was studied in healthy subjects in doses up to 300 mg daily for seven days without evidence of dose-limiting toxicities.

Febuxostat is indicated for the chronic management of hyperuricemia in patients with gout. Febuxostat is not recommended for the treatment of asymptomatic hyperuricemia.

Febuxostat is a non-purine, selective xanthine oxidase (XO) inhibitor. It decreases serum uric acid level by inhibiting xanthine oxidase, which is responsible for uric acid production. Xanthine oxidase breaks down hypoxanthine to xanthine and thus to uric acid. Febuxostat is not expected to inhibit other enzymes involved in purine and pyrimidine synthesis and metabolism at therapeutic concentrations.

Gout Flare: An increase in gout flares is frequently observed during initiation of anti-hyperuricemic agents, including Febuxostat. If a gout flare occurs during treatment, Febuxostat need not be discontinued. Prophylactic therapy (i.e., non-steroidal anti-inflammatory drug (NSAID) or colchicine upon initiation of treatment) may be beneficial for up to six months.

Cardiovascular Events: A higher rate of cardiovascular thromboembolic events was observed in patients treated with febuxostat than allopurinol in clinical trials. Monitor for signs and symptoms of MI and stroke.

Liver Enzyme Elevation: Transaminase elevations have been observed in febuxostat -treated patients. Monitor liver function tests periodically.
