There are also medications that help to decrease uric acid levels, which include xanthine oxidase inhibitors like allopurinol.

也有一些药物可以帮助降低尿酸含量，包呤氧化酶抑制剂，如醇。

Finally, there are some rare stones made of xanthine, which, just like uric acid, is a byproduct of purine breakdown.

最后，还有呤形成的罕见结石，同尿酸一样，是呤分解的副产物。

Xanthine oxidase is an enzyme involved in the breakdown of purines to uric acid, so inhibiting this enzyme results in less uric acid production.

呤氧化酶负责分解呤为尿酸，所以抑制这个酶，就可以减少尿酸的生成。
