Fludocyte 50mg Injection

Side Effects of Fludocyte 50mg Injection

Fever, chills, cough, dyspnoea, pneumonia; GI disturbances, stomatitis; oedema; tumour lysis syndrome; skin rashes; haemolytic anaemia, haemorrhagic cystitis; neurological disturbances including peripheral neuropathy, agitation, confusion, visual disturbances and coma. Progressive encephalopathy and blindness (high doses). Potentially Fatal: Myelosuppression. Fatal autoimmune haemolytic anemia.

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.

Contraindications

Renal impairment (CrCl <30 mL/min); decompensated haemolytic anaemia. Pregnancy and lactation. Concomitant use of live vaccines.

Mechanism of Action

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.

Special Precautions

Routine monitoring of blood counts and Hb conc. Monitor for signs of autoimmune haemolytic anaemia; elderly. Avoid contact with skin and eyes; avoid inhalation. Myelosuppression may be cumulative and severe increasing risk of opportunistic infections. Increased risk of tumour lysis syndrome in patients with high tumour burden.
