    Comments

    OTHER INFORMATION

    Potentially cardiotoxic Monitor blood uric acid and urea levels Rapidly taken up by the tissues, especially by the kidneys, liver, spleen and heart. Subsequent release of drug and metabolites is slow (T½ ~55 hrs). Rapidly metabolised in the liver, and the major metabolite daunorubicinol is also active. It is excreted slowly in the urine, mainly as metabolites with 25% excreted within 5 days. Biliary excretion accounts for 40–50% eliminationManufacturer’s literature suggests that in patients with a serum creatinine of 105–265 µmol/L the dose should be reduced to 75% of normal; if the creatinine is >265 µmol/L, the dose should be 50% of normalA liposomal formulation of daunorubicin is now available (DaunoXome ). Dilute to 0.2–1 mg/mL with glucose 5% and administer over 30–60 minutes
