How does Allopurinol work?
Allopurinol is a xanthine oxidase inhibitor. It inhibits the activity of xanthine oxidase, an enzyme involved in purine metabolism. Purine is a colourless crystalline compound with basic properties, forming uric acid on oxidation.
Allopurinol acts on purine catabolism, without disrupting the biosynthesis of purines. It reduces the production of uric acid by inhibiting the biochemical reactions immediately preceding its formation.
