A common misconception is that allopurinol is metabolized by its target, xanthine oxidase, but this action is principally carried out by aldehyde oxidase. The active metabolite of allopurinol is oxipurinol, which is also an inhibitor of xanthine oxidase. Allopurinol is almost completely metabolized to oxipurinol within two hours of oral administration, whereas oxipurinol is slowly excreted by the kidneys over 18–30 hours. For this reason, oxipurinol is believed responsible fo… WebFeb 17, 2024 · Before prescribing allopurinol, consider testing for the HLA-B*5801 allele in patients at elevated risk for developing severe cutaneous adverse reactions (SCAR) (including Koreans with CKD ≥ stage 3 and all patients of Han Chinese or Thai descent).
