Topiroxostat was approved by Pharmaceuticals Medical Devices Agency of Japan (PMDA) on June 28, 2013. It was co-developed and marketed as Uriadec®/Topiloric® by Sanwa Kagaku Kenkyusho & Fuji Yakuhin. Topiroxostat is a xanthine oxidase inhibitor. Xanthine oxidase (XO) is a type of enzyme that generates reductive oxygen species, which catalyze the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid. Topiroxostat could reduce the production of uric acid in the body through the inhibition of xanthine oxidase. It is usually used for the treatment of gout and hyperuricemia.

Sample Use Guides

In Vivo Use Guide

In general, for adults, the initial dose is started with 20mg of the active ingredient at a time, twice a day, in the morning and in the evening, and the dosage may be gradually increased according to your blood uric acid levels. The maintenance dose is usually 1 tablet (60mg) at a time, twice a day. The dosage may be adjusted according to the disease, age or symptoms. The maximum dosage is 80mg at a time, twice a day. This preparation contains 60mg of the active ingredient in a tablet.

Route of Administration: Oral
