Regrowth of hair usually resumes 3 weeks after therapy has been discontinued. Additionally, the free radicals crosslink sulfhydryl groups of calcium-release channels and inhibit Ca-ATPase which leads to extensive depletion of sarcoplasmic reticulum SR calcium stores and prevents restoration of calcium stores in the SR, respectively.

Epirubicin is a vesicant, and administration into soft tissue can cause pain, burning, tissue necrosis and skin ulcer. Attempt to aspirate the drug prior to removing the needle. The FDA approved epirubicin for the adjuvant treatment of node-positive breast cancer in September Following intravenous administration, epirubicin is widely distributed into tissues.

Because antineoplastic agents exert their toxic effects against rapidly growing cells, such as hematopoietic progenitor cells, sargramostim, GM-CSF, and filgrastim, G-CSF, are contraindicated for use in patients within 24 hours of treatment with antineoplastic agents. Epirubicin is rapidly and extensively metabolized by the liver and other tissues, including red blood cells.

Anaphylactoid reactions and urticaria may occur following epirubicin administration. Standard- and high-dose etoposide, ifosfamide, carboplatin, and etoposide in patients with small-cell lung cancer: Delayed emesis usually does not occur with epirubicin.

Passive immunoprophylaxis with immune globulins may be indicated for immunocompromised persons instead of, or in addition to, vaccination. Other mechanisms of resistance include changes in topoisomerase II and glutathione activity.

Concurrent use of epirubicin with other agents that cause bone marrow or immune suppression such as other antineoplastic agents or immunosuppressives may result in additive effects. Those undergoing chemotherapy should not be exposed to others who have recently received the oral poliovirus vaccine OPV.

Epirubicin has a similar spectrum of activity and toxicity as doxorubicin. Acute cardiotoxicity can medanismo during administration of epirubicin; a cumulative, dose-dependent cardiomyopathy may also occur.
