Allopurinol is widely used in the treatment of gout. The main metabolic pathway of allopurinol is its oxidation to oxypurinol. Pyrazinamide is an antituberculous drug. One of the main metabolic pathways of pyrazinamide is its oxidation to 5-hydroxypyrazinamide. The oxidation of allopurinol and pyrazinamide is known to be attributed to xanthine oxidase1, 2. However, it has been suggested that aldehyde oxidase also participates in the oxidation of these agents3, 4. Therefore, we investigated whether aldehyde oxidase plays a role in the oxidation of allopurinol and pyrazinamide by in vivo and in vitro studies.
