Mercaptopurin/ azathioprin Selv om der ikke er udført interaktionsundersøgelser med febuxostat, ved man, at hæmning af xanthinoxidase (XO) resulterer i forhøjede mercaptopurin - eller azathioprinniveauer.
Mercaptopurine/ azathioprine Although interaction studies with febuxostat have not been performed, inhibition of xanthine oxidase (XO) is known to result in an increase in mercaptopurine or azathioprine levels.
