Overview

ℹ️

What is this medicine?

Doxorubicin liposomal is a chemotherapy medicine used to treat certain types of cancer, including ovarian cancer, breast cancer, and a type of skin cancer called Kaposi's sarcoma. It works by stopping the growth of cancer cells. This special 'liposomal' form helps the medicine stay in your body longer and get into the cancer cells more effectively, while potentially reducing some side effects on the heart compared to the regular form of doxorubicin.

Pharmacology

🔬

Mechanism of Action

Doxorubicin is an anthracycline antibiotic that exerts its cytotoxic effects through several mechanisms: 1) Intercalation into DNA, leading to inhibition of macromolecular biosynthesis (DNA and RNA synthesis). 2) Inhibition of topoisomerase II, an enzyme critical for DNA replication and repair, resulting in DNA strand breaks. 3) Generation of free radicals (e.g., superoxide radicals, hydroxyl radicals) which cause oxidative damage to DNA, proteins, and cell membranes. The liposomal formulation encapsulates doxorubicin in pegylated liposomes, which prolongs its circulation time, alters its tissue distribution (preferential accumulation in tumor tissues with leaky vasculature), and reduces uptake by the heart, thereby decreasing cardiotoxicity compared to conventional doxorubicin.

Advise females of reproductive potential to use effective contraception during treatment and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 6 months after the last dose.

Trimester-Specific Risks:

First Trimester: High risk of major birth defects and fetal loss due to rapid cell division during organogenesis.
Second Trimester: Continued risk of fetal toxicity, including myelosuppression and growth restriction.
Third Trimester: Risk of fetal toxicity, including myelosuppression; potential for premature birth.
🤱

Lactation

It is not known whether doxorubicin liposomal is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in breastfed infants, advise women not to breastfeed during treatment and for 10 days after the last dose.

Infant Risk: L5 (Contraindicated - significant risk to infant)
👶

Pediatric Use

Safety and effectiveness have not been established in pediatric patients. Use in pediatric patients is generally not recommended.

👴

Geriatric Use

No overall differences in safety or effectiveness were observed between elderly patients and younger patients. However, greater sensitivity of some older individuals cannot be ruled out. Close monitoring for adverse effects is recommended.

Clinical Information

💎

Clinical Pearls

  • The liposomal formulation significantly reduces the risk of cardiotoxicity compared to conventional doxorubicin, but cardiac monitoring is still essential, especially with higher cumulative doses.
  • Palmar-plantar erythrodysesthesia (PPE), or hand-foot syndrome, is a common and dose-limiting toxicity unique to the liposomal formulation. Management includes dose reduction/interruption, cooling, emollients, and sometimes pyridoxine.
  • Infusion-related reactions are common and can be severe. Administer slowly (over at least 60 minutes) and consider premedication (antihistamines, corticosteroids) for patients with prior reactions.
  • Extravasation is less likely to cause severe local tissue damage than conventional doxorubicin, but the infusion site should still be monitored closely.
  • Cumulative lifetime dose limits for doxorubicin liposomal are higher than for conventional doxorubicin due to reduced cardiotoxicity, but individual patient risk factors (prior anthracycline exposure, pre-existing cardiac disease) must be considered.
