How does Allopurinol work in the body?
Allopurinol works by inhibiting the enzyme xanthine oxidase, which is responsible for converting hypoxanthine and xanthine into uric acid. By blocking this enzyme, Allopurinol effectively reduces the production of uric acid in the body. This reduction helps to prevent the formation of uric acid crystals, thereby alleviating symptoms associated with gout and preventing complications such as kidney stones. The mechanism of action of Allopurinol makes it a crucial medication for managing conditions related to hyperuricemia.
