P - Contraindicated in Pregnancy
L - Contraindicated in lactation

It is a cytotoxic chemotherapeutic agent.


Fludarabine is rapidly dephosphorylated to 2-fluoro-ara-A and then phosphorylated intracellularly by deoxycytidine kinase to the active triphosphate, 2-fluoro-ara-ATP which inhibits DNA polymerase and ribonucleotide reductase resulting in inhibition of DNA synthesis leading to cell death.



Metabolism: IV: Fludarabine phosphate is rapidly dephosphorylated in the serum to fludarabine which enters the tumor cells to be rephosphorylated to the active triphosphate derivative.                                                     Excretion: Mostly in the urine, about 60% of dose is excreted within 24 hr.

Myelosuppression may be cumulative and severe increasing risk of opportunistic infections. Increased risk of tumour lysis syndrome in patients with high tumour burden.

Other Drug Interactions

Co-administration with pentostatin may lead to pulmonary toxicity. Reduced metabolic activation of fludarabine with cytarabine. Reduced therapeutic efficacy with dipyridamole and other adenosine uptake inhibitors.
