Dược Lực Học : Allopurinol, a structural analog of the natural purine base hypoxanthine, is used to prevent gout and renal calculi due to either uric acid or calcium oxalate and to treat uric acid nephropathy, hyperuricemia, and some solid tumors.
Cơ Chế Tác Dụng : A xanthine oxidase inhibitor that decreases uric acid production. It also acts as an antimetabolite on some simpler organisms. [PubChem] Allopurinol and its active metabolite, oxypurinol, inhibits the enzyme xanthine oxidase, blocking the conversion of the oxypurines hypoxanthine and xanthine to uric acid. Elevated concentrations of oxypurine and oxypurine inhibition of xanthine oxidase through negative feedback results in a decrease in the concentrations of uric acid in the serum and urine. Allopurinol also facilitates the incorporation of hypoxanthine and xanthine into DNA and RNA, leading to a feedback inhibition of de novo purin synthesis and a decrease in serum uric acid concentrations as a result of an increase in nucleotide concentration.
Dược Động Học :
▧ Absorption :
Approximately 80-90% absorbed from the gastrointestinal tract.
▧ Protein binding :
Allopurinol and oxypurinol are not bound to plasma proteins
▧ Metabolism :
Hepatic
▧ Route of Elimination :
Approximately 20% of the ingested allopurinol is excreted in the feces.
▧ Half Life :
1-3 hours
Độc Tính : LD50=214 mg/kg (in mice)
Chỉ Định : For the treatment of hyperuricemia associated with primary or secondary gout. Also indicated for the treatment of primary or secondary uric acid nephropathy, with or without the symptoms of gout, as well as chemotherapy-induced hyperuricemia and recurrent renal calculi.
Tương Tác Thuốc :
  • Acenocoumarol Allopurinol may increase the anticoagulant effect of acenocoumarol.
  • Anisindione Allopurinol may increase the anticoagulant effect of anisindione.
  • Azathioprine Allopurinol may increase the effect of thiopurine, azathioprine.
  • Cyclosporine Allopurinol increases the effect and toxicity of cyclosporine
  • Dicoumarol Allopurinol may increase the anticoagulant effect of dicumarol.
  • Mercaptopurine Allopurinol may increase the effect of thiopurine, mercaptopurine.
  • Trandolapril The ACE inhibitor, Trandolapril, may increase the risk of hypersensitivity reactions to Allopurinol.
  • Warfarin Allopurinol may increase the anticoagulant effect of warfarin. Monitor for changes in prothrombin times and therapeutic effects of warfarin if allopurinol is initiated, discontinued or dose changed.
