Salmeterol Xinafoate

Long-acting bronchodilator similar in structure to salbutamol. Inhaled twice daily administration.

At the date of last update we did not find published data on its excretion in breast milk.

Its high binding to plasma proteins, very large volume of distribution, moderately high molecular weight and the fact that, after inhalation, it reaches very low or undetectable plasma concentrations ^{(Hale, Cazzola 2002, AEMPS 2012)} make it very unlikely that significant quantities will pass into milk.

Terbutaline, a molecule of the same family, is excreted in negligible amounts in breast milk.

Several medical societies and expert authors consider the use of inhaled bronchodilators safe during breastfeeding due to low maternal serum levels ^{(Lactmed, Bendien 2024, Amir 2011, National Asthma 2004, Nelson 2001, Ellsworth 1994).}
