When cancer cells are killed by therapy, they may spill their inner intracellular contents, which accumulate in the body faster than can be eliminated.

Clinically relevant Pmediated drug-drug interactions are therefore not anticipated in patients treated with the recommended Elitek dose and dosing schedule. Discontinue nursing or Elitek taking into account the importance of the drug to the mother 8. The uric acid failure status in those patients is unknown. Blood must be collected into pre-chilled tubes containing heparin anticoagulant. Screen patients at higher risk for G6PD deficiency e.

Tumor lysis syndrome is caused by the sudden, rapid death of cells, particularly cancer cells in patients with leukemia or lymphoma, in response to cancer therapies.

Special sample handling procedure must be followed to avoid ex vivo uric acid degradation [ see Boxed WarningDrug Interactions 7 ]. All but one patient in the Elitek arm had reduction and maintenance of uric acid levels to within or below the normal range during the treatment.


Dosage The recommended dose of Elitek is 0. Tumor lysis syndrome may occur spontaneously, although the occurrence of this is rare. Control of plasma uric acid in adults at risk for tumor lysis syndrome: Each subunit is made up of a single amino acid polypeptide chain with a molecular mass of about 34 kDa.

The measurement of plasma uric acid was used to evaluate the effectiveness of rasburicase in clinical studies. The drug product is a sterile, white to off-white, lyophilized powder intended for intravenous administration following reconstitution with a diluent. Among the adult patients in Study 4, hypersensitivity reactions occurred in 4.

Methemoglobinemia Elitek can result in methemoglobinemia in some patients. May cause fetal harm. Do not use filters during infusion of prdscribing Elitek drug product.

Elitek is supplied in 3 mL and 10 mL colorless, glass vials containing rasburicase at a concentration of 1. International journal of medical sciences. The primary efficacy objective was determination of the proportion of patients with maintained plasma uric acid concentration at 48 hours as defined for Study 2 above. The study population demographics were: Immediately and permanently discontinue Elitek administration in any patient developing clinical evidence of a serious hypersensitivity reaction [ see Boxed WarningContraindications 4Adverse Reactions 6.

Dosing beyond 5 days or administration of more than one course is not recommended.

What can patients do to help alleviate or prevent discomfort and side effects? In adults, age, gender, baseline liver enzymes prescibing creatinine clearance did not impact the pharmacokinetics of rasburicase.
