適應症
Gout: Management of primary or secondary gout (acute attack, tophi, joint destruction, uric acid lithiasis, and/or nephropathy).
Nephrolithiasis, prevention of recurrent calcium stones: Management in patients with hyperuricosuria (uric acid excretion >800 mg/day in men and >750 mg/day in women).
Tumor lysis syndrome, prevention of hyperuricemia associated with malignancy: Management of hyperuricemia associated with cancer treatment for leukemia, lymphoma, and other malignancies.
藥理
Antigout Agent; Xanthine Oxidase Inhibitor
Allopurinol inhibits xanthine oxidase, the enzyme responsible for the conversion of hypoxanthine to xanthine to uric acid.
藥動學
  • Onset of action:
  • Gout: 2 to 3 days (decrease in serum and urine uric acid); 1 week or longer (peak effect); normal serum urate levels achieved typically within 1 to 3 weeks.
    Cancer therapy-induced hyperuricemia: 27 hours (Median time to plasma uric acid control)
  • Absorption: 90% from GI tract.
  • Distribution: Vss: ~0.87 ± 0.13 L/kg.
  • Metabolism: Rapidly oxidized via the liver to active metabolites, primarily oxypurinol.
  • Bioavailability: ~49% to 53%.
  • Half-life elimination: ~1 to 2 hours (Parent drug); ~15 hours (Oxypurinol).
  • Time to peak, plasma: 1.5 hours (Allopurinol); 4.5 hours (Oxypurinol).
  • Excretion: Urine (76% as oxypurinol, 12% as unchanged drug); feces (~20%).

    腎功能調整劑量
    1. eGFR (mL/minute/1.73 m2) > 30~60:50 mg daily

    3. eGFR (mL/minute/1.73 m2) = 5~15:50 mg twice weekly
    4. eGFR (mL/minute/1.73 m2) < 5:50 mg once weekly
    肝功能調整劑量
