How It Works (Mechanism of Action)

Allopurinol works by reducing the production of uric acid in the body. It does this by inhibiting an enzyme called xanthine oxidase, which is involved in the breakdown of purines into uric acid. By lowering uric acid levels, it helps prevent gout attacks and the formation of kidney stones.

In scientific terms, Allopurinol is a competitive inhibitor of xanthine oxidase. This inhibition leads to increased levels of hypoxanthine and xanthine, which are more soluble than uric acid. Consequently, this process helps to decrease the overall uric acid concentration in the blood and urine, thereby reducing the risk of crystal formation.
