Description:
There are various agents used to treat the symptoms of gout E.g. Allopurinol (Zyloprim), Probenecid or Colchicine. Colchicine reduces and decreases inflammation and the deposition of uric acid in joints. Sulfinpyrazone increases uric acid secretion, thus lowering levels of uric acid in the body. Probenecid is used to treat chronic gout and increase blood levels of the penicillins and cephalosporins. Probenecid increases the excretion of uric acid and reduces penicillin excretion. Allopurinol is a prescription drug classified for use in gout, and other conditions in which uric acid levels are high(see gout), kidney stones. This drug acts to inhibit the enzyme xanthine oxidase, thus slowing the formation of uric acid. (Drug Facts and Comparisons 1999)
