Uxotor 40 Tablet

Febuxostat is a xanthine oxidase (XO) inhibitor indicated for the chronic management of hyperuricemia in adult patients with gout who have an inadequate response to a maximally titrated dose of allopurinol, who are intolerant to allopurinol, or for whom treatment with allopurinol is not advisable. Limitations of Use: Febuxostat tablets are not recommended for the treatment of asymptomatic hyperuricemia.

Boxed warning. CARDIOVASCULAR DEATH Gout patients with established cardiovascular (CV) disease treated with Febuxostat tablets had a higher rate of CV death compared to those treated with allopurinol in a CV outcomes study. Consider the risks and benefits of Febuxostat tablets when deciding to prescribe or continue patients on Febuxostat tablets. Febuxostat tablets should only be used in patients who have an inadequate response to a maximally titrated dose of allopurinol, who are intolerant to allopurinol, or for whom treatment with allopurinol is not advisable. WARNING: CARDIOVASCULAR DEATH See full prescribing information for complete boxed warning. Gout patients with established cardiovascular (CV) disease treated with Febuxostat had a higher rate of CV death compared to those treated with allopurinol in a CV outcomes study. Consider the risks and benefits of Febuxostat when deciding to prescribe or continue patients on Febuxostat. Febuxostat should only be used in patients who have an inadequate response to a maximally titrated dose of allopurinol, who are intolerant to allopurinol, or for whom treatment with allopurinol is not advisable. Gout Flares: An increase in gout flares is frequently observed after initiation of Febuxostat. If a gout flare occurs during treatment, Febuxostat need not be discontinued. Prophylactic therapy (i.e., non-steroidal anti-inflammatory drug or colchicine) upon initiation of treatment may be beneficial for up to six months. Hepatic Effects: Cases of hepatic failure, some fatal, have been reported. If liver injury is detected, promptly interrupt Febuxostat and treat cause, if possible, to resolution or stabilization. Permanently discontinue Febuxostat if liver injury is confirmed, and no alternate etiology can be found. Serious Skin Reactions: Serious skin and hypersensitivity reactions, including Stevens-Johnson syndrome, drug reaction with eosinophilia and systemic symptoms and toxic epidermal necrolysis have been reported in patients taking Febuxostat. Discontinue Febuxostat if serious skin reactions are suspected. Cardiovascular Death In a cardiovascular (CV) outcome study, gout patients with established CV disease treated with Febuxostat had a higher rate of CV death compared to those treated with allopurinol. Sudden cardiac death was the most common cause of adjudicated CV deaths, 2.7% in the Febuxostat group (83 of 3,098) as compared to 1.8% in the allopurinol group (56 of 3,092). Febuxostat was similar to allopurinol for nonfatal myocardial infarction (MI), nonfatal stroke and unstable angina with urgent coronary revascularization.

The following serious adverse reactions are described elsewhere in the prescribing information: Cardiovascular Death Hepatic Effects Serious Skin Reactions Adverse reactions in ≥ 1% of patients treated with Febuxostat are liver function abnormalities, nausea, arthralgia, and rash. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In Phase 2 and 3 clinical studies, a total of 2757 patients with hyperuricemia and gout were treated with Febuxostat 40 mg or 80 mg daily. For Febuxostat 40 mg, 559 patients were treated for ≥6 months. For Febuxostat 80 mg, 1377 patients were treated for ≥6 months, 674 patients were treated for ≥1 year and 515 patients were treated for ≥2 years. In the CARES study, a total of 3098 patients were treated with Febuxostat 40 mg or 80 mg daily; of these, 2155 patients were treated for ≥1 year and 1539 were treated for ≥2 years. Most Common Adverse Reactions In three randomized, controlled clinical studies (Studies 1, 2 and 3), which were 6 to 12 months in duration, the following adverse reactions were reported by the treating physician as related to study drug. Table 1 summarizes adverse reactions reported at a rate of at least 1% in Febuxostat treatment groups and at least 0.5% greater than placebo. * Of the patients who received allopurinol, 10 received 100 mg, 145 received 200 mg, and 1122 received 300 mg, based on level of renal impairment. Table 1: Adverse Reactions Occurring in ≥1% of Patients Treated with Febuxostat and at Least 0.5% Greater than in Patients Receiving Placebo in Controlled Studies Adverse Reactions Placebo Febuxostat allopurinol* (N=134) 40 mg daily (N=757) 80 mg daily (N=1279) (N=1277) Liver Function Abnormalities 0.7% 6.6% 4.6% 4.2% Nausea 0.7% 1.1% 1.3% 0.8% Arthralgia 0% 1.1% 0.7% 0.7% Rash 0.7% 0.5% 1.6% 1.6% The most common adverse reaction leading to discontinuation from therapy was liver function abnormalities in 1.8% of Febuxostat 40 mg, 1.2% of Febuxostat 80 mg, and in 0.9% of patients treated with allopurinol. In addition to the adverse reactions presented in Table 1, dizziness was reported in more than 1% of patients treated with Febuxostat although not at a rate more than 0.5% greater than placebo.
