Glatiramer Acetate
A synthetic polypeptide of 4 amino acids (l-alanine, l-glutamic, l-lysine and l-tyrosine), similar to myelin which is indicated in recurrences of multiple sclerosis (Ziemssen 2001).
Its high molecular weight makes it unlikely it will be excreted in breast milk and due to its protein nature it would be destroyed in the stomach of the infant, not absorbed, so its oral bioavailability is practically zero, except in premature babies and in the immediate neonatal period, where there may be greater intestinal permeability (2016 Almas, Cree 2013).
No problems have been observed in breastfeeding infants for periods ranging from 1 to 12 months whose mothers were taking glatiramer (Fragoso 2014, Hellwig 2012 and 2011, Fragoso 2010).
Glatiramer injected subcutaneously is hydrolyzed locally in amino acids and short peptides, so there are no appreciable levels of glatiramer in plasma. Severe side effects are unusual.
For some authors (Fragoso 2014) glatiramer would be the best multiple sclerosis disease-modifying drug to take during breastfeeding. One in 10 neurologists prescribe it during breastfeeding (Coyle 2004).
