Febuxostat (INN; trade names Adenuric in Europe and New Zealand, Uloric in the US, Goturic in Latin America, Feburic in Japan) is a drug that inhibits xanthine oxidase, thus reducing production of uric acid in the body. It is used in the treatment of chronic gout and hyperuricemia.

Febuxostat was discovered by scientists at the Japanese pharmaceutical company Teijin in 1998. Teijin partnered the drug with TAP Pharmaceuticals in the US and Ipsen in Europe. Ipsen obtained marketing approval for febuxostat from the European Medicines Agency in April 2008, Takeda obtained FDA approval in February 2009, and Teijin obtained approval from the Japanese "Pharmaceuticals and Medical Devices Agency" in 2011.

Medical uses

Febuxostat is used to treat chronic gout and hyperuricemia.[3] National Institute for Health and Clinical Excellence concluded that febuxostat is more effective than standard doses of allopurinol, but not more effective than higher doses of allopurinol.[3]

Uloric 40 mg tablet

Febuxostat is in the US pregnancy category C; there are no adequate and well-controlled studies in pregnant women.[4]

Side effects

The adverse effects associated with febuxostat therapy include nausea, diarrhea, arthralgia, headache, increased hepatic serum enzyme levels and rash.[4][5]

Drug interactions

Febuxostat is contraindicated with concomitant use of theophylline and chemotherapeutic agents, namely azathioprine and 6-mercaptopurine, because it could increase blood plasma concentrations of these drugs, and therefore their toxicity.[4][6]

Mechanism of action

Febuxostat is a non-purine-selective inhibitor of xanthine oxidase.[4] It works by non-competitively blocking the molybdenum pterin center which is the active site on xanthine oxidase. Xanthine oxidase is needed to successively oxidize both hypoxanthine and xanthine to uric acid. Hence, febuxostat inhibits xanthine oxidase, therefore reducing production of uric acid. Febuxostat inhibits both oxidized as well as reduced form of xanthine oxidase because of which febuxostat cannot be easily displaced from the molybdenum pterin site.[5]

History

Febuxostat was discovered by scientists at the Japanese pharmaceutical company Teijin in 1998.[7] Teijin partnered the drug with TAP Pharmaceuticals in the US and Ipsen in Europe.[8][9][10]

Ipsen obtained marketing approval for febuxostat from the European Medicines Agency in April 2008,[11] Takeda obtained FDA approval in February 2009,[12][13] and Teijin obtained approval from the Japanese authorities in 2011.[14] Ipsen exclusively licensed its European rights to Menarini in 2009.[15] Teijin partnered with Astellas for distribution in China and southeast Asia.[16][17]

Society and culture

Cost

In the UK, NICE has found that febuxostat has a higher cost/benefit ratio than allopurinol and on that basis recommended febuxostat as a second-line drug for people who cannot use allopurinol.[3]

Trade names

Febuxostat is marketed as Adenuric in Europe and New Zealand, Uloric in the US, Goturic and Goutex in Latin America, Feburic in Japan, and is generic in several countries and is available by many names in those countries.[1]
