More information

  • Usage

    Allopurinol (Zyloprim) is a xanthine oxidase enzyme inhibitor medication. Allopurinol (Zyloprim) is used for managing patients with signs of primary or secondary gout, certain patients with leukemia and lymphoma, and some patients with recurrent calcium oxalate calculi and high uric acid excretion. Gout is a disorder of the metabolism (hyperuricemia) that is characterized by the deposition of monosodium urate in tissues such as the joints. Zyloprim (allopurinol) works by reducing the production of uric acid by acting on purine catabolism. Similar to the purine base hypoxanthine, Zyloprim inhibits the enzymatic activity of xanthine oxidase and interferes with the conversion of xanthine to uric acid. Serum and urinary uric acid levels are typically observed to drop within three days of Zyloprim administration and depends on the dose of allopurinol given. Allopurinol is sometimes used with colchicine and indomethacin in gout patients.
