What Is An Extravasation?

Extravasation is the process by which any liquid (fluid or drug) accidentally leaks into the surrounding tissue, instead of the venous system1,2

Anthracycline extravasation

  • Anthracyclines are vesicant chemotherapy agents that may cause severe and irreversible tissue damage when accidental extravasation occurs.3,4
  • Examples of commonly used anthracyclines include: epirubicin, doxorubicin, and daunorubicin.
  • Anthracyclines bind to the nuclear DNA of cells, causing cell death.5
  • The dead cells release bound anthracycline creating a continuing cycle of tissue damage as the anthracycline is recirculated in the tissue.6
  • While believed to be under-reported, anthracycline extravasation is estimated to occur in 0.1% to 1% of all patients receiving treatment.7

INDICATION: TOTECT® (dexrazoxane) is indicated for the treatment of extravasation resulting from intravenous anthracycline chemotherapy.

IMPORTANT DOSAGE AND ADMINISTRATION INSTRUCTIONS
Vial contents must be mixed and diluted with 50 mL of 0.167 M sodium lactate injection solution before use. The TOTECT dose should be reduced by 50% in patients with creatinine clearance
values < 40 mL/min.

IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS

None.

WARNINGS AND PRECAUTIONS
Myelosuppression: TOTECT is associated with leukopenia, neutropenia, and thrombocytopenia. Perform hematological monitoring.
Use in Pregnancy: Fetal harm can occur when administered to a pregnant woman. Apprise women of potential harm to the fetus.

ADVERSE REACTIONS
In the clinical studies, TOTECT was administered to patients also receiving chemotherapeutic agents for cancer, and the adverse reaction profile reflects the combination of TOTECT, underlying disease, and already administered chemotherapy. The most common adverse reactions (≥16%) are nausea, fever, injection site pain and vomiting.
