- Pharmacodynamics
Not Available
- Mechanism of action
Oxypurinol inhibits the enzyme xanthine oxidase, blocking the conversion of the oxypurines hypoxanthine and xanthine to uric acid. Elevated concentrations of oxypurine and oxypurine inhibition of xanthine oxidase through negative feedback results in a decrease in the concentrations of uric acid in the blood and urine. Oxypurinol also facilitates the incorporation of hypoxanthine and xanthine into DNA and RNA, resulting in further reductions of serum uric acid concentrations.
