Benzbromarone (INN) is a uricosuric agent used in the treatment of gout, especially when allopurinol, a first-line treatment, fails or produces intolerable adverse effects. It is structurally related to the antiarrhythmic amiodarone.[1]

Benzbromarone is highly effective and well-tolerated,[2][3][4][5] and clinical trials as early as 1981 and as recently as April 2008 have suggested it is superior to both allopurinol and probenecid, another uricosuric drug.[6][7]

[edit] Effect on cytochrome P450

Benzbromarone is a very potent inhibitor of CYP2C9.[8][1] Several analogues of the drug have been developed as CYP2C9 and CYP2C19 inhibitors for use in research.[9][10]
