48. Which of the following statements explains why allopurinol is able to prevent gout? (A) It binds to uric acid thus preventing the formation of uric acid crystals. (B) It acts as a diuretic to increase the elimination of uric acid. (C) It inhibits the production of uric acid and allows for the more highly soluble xanthine and hypoxanthine to be excreted from the body. (D) It stimulates the purine salvage pathway, thus eliminating the need for production of uric acid. (E) None of the above.
