Breastfeeding brings many positive effects on the health and wellbeing of both mother and child. But breastfeeding mothers get sick like the rest of us, which means they also need medicines. We believe that each woman should have the right to make decisions about breastfeeding based on information she can trust. We are providing one step in that direction, developing a model for how medicines transfer to milk!
Studying how different substances transfer to milk is difficult and complex, and until now there has been almost no information how safe it is to use a particular drug while breastfeeding. This means that women often have to choose between breastfeeding and treatments they need. ConcePTION is collecting and analyzing milk samples from women who use medicines while breastfeeding. But that kind of study is not always possible, and in some cases not a risk we want to take. For the times we can’t test milk, we need a non-clinical platform that combines methods that helps predict the safety profile of a particular drug.
One of the teams in ConcePTION, work package 3, is using a combination of in vitro (cell lines), in vivo (animal models) and in silico models that will allow fast and reliable predictions on how a substance transfers to human breast milk. Want to know more about how it works? Nina Nauwelarts (PhD student) and Kelly Janssens (lactation consultant) from UZ Leuven, Neonatology, explains how it works! The video has subtitles in English, Spanish and Dutch.
Nina Nauwelarts is one of the authors of a comprehensive review of the non-clinical methods that can be used to study how a medicine transfers to breast milk.
