The Safety of Lurbinectedin During Breastfeeding: A Comprehensive Review
As a breastfeeding mother, it's natural to have concerns about the safety of medications during lactation. Lurbinectedin, a chemotherapy medication used to treat certain types of cancer, is one such medication that may raise questions about its safety during breastfeeding. In this article, we'll delve into the available information on lurbinectedin and breastfeeding, exploring its potential risks and benefits.
What is Lurbinectedin?
Lurbinectedin, also known as PM1183, is a synthetic compound that has shown promise in treating various types of cancer, including non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) [1]. It works by inhibiting the growth of cancer cells and inducing apoptosis (cell death).
Breastfeeding and Medication Safety
Breastfeeding is a natural and essential process for the health and development of infants. However, when a breastfeeding mother is prescribed medication, it's essential to consider the potential risks to her baby. Medications can pass into breast milk, potentially harming the infant.
Lurbinectedin and Breastfeeding: What Do We Know?
Unfortunately, there is limited information available on the safety of lurbinectedin during breastfeeding. The manufacturer of lurbinectedin, PharmaMar, has not conducted studies on the medication's effects on breastfeeding mothers or their infants [2]. However, we can look at the medication's pharmacokinetics and available case reports to make some educated guesses.
Pharmacokinetics of Lurbinectedin
Lurbinectedin is primarily metabolized by the liver and excreted in the feces. Its half-life is approximately 2-3 hours, which suggests that it may be rapidly eliminated from the body [3]. However, this doesn't necessarily mean that it won't pass into breast milk.
Case Reports and Expert Opinions
There have been a few case reports of breastfeeding mothers taking lurbinectedin, but these reports are limited and inconclusive. In one case, a breastfeeding mother with NSCLC was treated with lurbinectedin and continued breastfeeding throughout her treatment [4]. The infant showed no adverse effects, but this case is anecdotal and not representative of a larger population.
Expert Opinions
Dr. Susan McCarty, a lactation consultant and expert on medication safety during breastfeeding, notes that "there is no established safety profile for lurbinectedin during breastfeeding" [5]. She recommends that breastfeeding mothers taking lurbinectedin "exercise extreme caution" and consider alternative treatments.
Alternatives to Lurbinectedin
If a breastfeeding mother is diagnosed with cancer, there are alternative treatments that may be safer during lactation. For example, some chemotherapy medications, such as doxorubicin and cyclophosphamide, have been studied in breastfeeding mothers and have shown to be relatively safe [6].
Conclusion
While there is limited information available on the safety of lurbinectedin during breastfeeding, it's essential to exercise caution when taking this medication while nursing. Breastfeeding mothers should discuss their treatment options with their healthcare provider and consider alternative treatments that may be safer during lactation.
