Patients who have serum ALT more than 3 times the upper limit of normal (ULN) with serum total bilirubin more than 2 times the ULN without alternative etiologies are at risk for severe drug-induced liver injury. Since the long-term safety of exposure to 1-methylxanthine in humans is unknown, use with caution when coadministering febuxostat with aminophylline. Aminophylline is converted to the active form, theophylline, in the body. Steady-state serum uric acid concentration may be reached within 7 days of therapy initiation. After antineoplastic therapy, tumor cell breakdown may greatly increase the rate of purine metabolism to uric acid. As there has been no experience with febuxostat, its use in these populations is not recommended. endobj Febuxostat is an oral, non-purine selective xanthine oxidase inhibitor (XOI). (See Interactions.). Inhibition of xanthine oxidase by febuxostat may increase plasma concentrations of drugs metabolized by the enzyme, resulting in toxicity. There is no appreciable accumulation when doses of 10 mg to 240 mg are administered every 24 hours. As with allopurinol, it is advisable for patients to maintain a urine output >= 2 L/day in an attempt to avoid the formation of xanthine calculi under the influence of xanthine oxidase inhibitor therapy and to help prevent renal precipitation of urates in patients receiving concurrent uricosuric agents. Rosuvastatin: (Moderate) Do not exceed a rosuvastatin dose of 20 mg once daily if concomitant use of febuxostat is necessary. APEX study: During the 8-week prophylaxis period, a greater proportion of subjects in the febuxostat 120 mg (36%) treatment group required treatment for gout flare compared to febuxostat 80 mg (28%), allopurinol 300 mg (23%) and placebo (20%). WARNINGS AND PRECAUTIONS, Endocrine and Metabolism section. In clinical trials, less than 1% of patients experienced renal or urinary disorders. Gout flares may occur during initiation of treatment due to changing serum uric acid levels resulting in mobilization of urate from tissue deposits (see section 4.8 and 5.1).
