Topiroxostat is an orally-administered, non-purine, selective
xanthine oxidase (XO) inhibitor developed for the treatment of
hyperuricemia specifically for patients with gout in Japan. The
drug was discovered and developed by Fuji Yakuhin. In contrast
to conventional XO inhibitors such as febuxostat, topiroxostat
interacts with key amino acid residues of the solvent channel.
