Epirubicin

Description

An anthracycline which is the 4'-epi-isomer of doxorubicin. The compound exerts its antitumor effects by interference with the synthesis and function of DNA. [PubChem]

Indication

For use as a component of adjuvant therapy in patients with evidence of axillary node tumor involvement following resection of primary breast cancer.

Mechanism of Action

Epirubicin has antimitotic and cytotoxic activity. It inhibits nucleic acid (DNA and RNA) and protein synthesis through a number of proposed mechanisms of action: Epirubicin forms complexes with DNA by intercalation between base pairs, and it inhibits topoisomerase II activity by stabilizing the DNA-topoisomerase II complex, preventing the religation portion of the ligation-religation reaction that topoisomerase II catalyzes. It also interferes with DNA replication and transcription by inhibiting DNA helicase activity.

Pharmacokinetics

Absorption
100%
Distribution
* 21 ± 2 L/kg [60 mg/m2 Dose] * 27 ± 11 L/kg [75 mg/m2 Dose] * 23 ± 7 L/kg [120 mg/m2 Dose] * 21 ± 7 L/kg [150 mg/m2 Dose]
Metabolism
Extensively and rapidly metabolized in the liver. Epirubicin is also metabolized by other organs and cells, including red blood cells. The four main metabolic routes are: (1) reduction of the C-13 keto-group with the formation of the 13(S)-dihydro derivative, epirubicinol; (2) conjugation of both the unchanged drug and epirubicinol with glucuronic acid; (3) loss of the amino sugar moiety through a hydrolytic process with the formation of the doxorubicin and doxorubicinol aglycones; and (4) loss of the amino sugar moiety through a redox process with the formation of the 7-deoxy-doxorubicin aglycone and 7-deoxy-doxorubicinol aglycone. Epirubicinol exhibits in vitro cytoxic activity (~10% that of epirubicin), but it is unlikely to reach sufficient concentrations in vivo to produce cytotoxic effects.
Elimination

Clearance

* 65 +/- 8 L/hour [Patients1 with Solid Tumors Receiving Intravenous Epirubicin 60 mg/m2] * 83 +/- 14 L/hour [Patients1 with Solid Tumors Receiving Intravenous Epirubicin 75 mg/m2] * 65 +/- 13 L/hour [Patients1 with Solid Tumors Receiving Intravenous Epirubicin 120 mg/m2] * 69 +/- 13 L/hour [Patients1 with Solid Tumors Receiving Intravenous Epirubicin 150 mg/m2]
