Chỉ số theo dõi
Monitor CBC with differential, platelet count; serum albumin, AST, ALT, serum creatinine, uric acid. Assess for signs and symptoms of haemolysis, infection, neurotoxicity and tumour lysis syndrome.
May decrease therapeutic effect with dipyridamole and other adenosine uptake inhibitors. May diminish the therapeutic effect of live vaccines. Potentially Fatal: Increased risk of pulmonary toxicity with pentostatin; concomitant use is not recommended.
Tác dụng
Description: Mechanism of Action: Fludarabine is a synthetic purine antagonist antimetabolite. It is rapidly dephosphorylated to 2-fluoro-ara-A and then phosphorylated intracellularly by deoxycytidine kinase to form the active triphosphate, 2-fluoro-ara-ATP. This active metabolite inhibits the DNA polymerase, ribonucleotide reductase, DNA primase and DNA ligase, resulting in the inhibition of DNA synthesis. Pharmacokinetics: Absorption: Bioavailability: 50-65% (oral). Time to peak plasma concentration: 1-2 hours (oral). Distribution: Plasma protein binding: Approx 19-29%. Metabolism: Rapidly dephosphorylated in the plasma into 2-fluoro-ara-A (active metabolite), which then enters the tumour cells and is phosphorylated by deoxycytidine kinase to form 2-fluoro-ara-ATP (active triphosphate derivative). Excretion: Mainly via urine. Elimination half-life: Approx 20 hours.
