Long-acting agonist of the glucagon-like peptide receptor type 1 (GLP-1) that stimulates the endogenous secretion of insulin and decreases that of glucagon.
Used in type 2 diabetes in combination with other oral anti-diabetics, especially metformin.
Subcutaneous administration once a week.

There is risk of hypoglycaemia even in monotherapy.

Since the last update, we have not found published data on its excretion in breast milk.

Its pharmacokinetic data (very high molecular weight) make it very unlikely that it will be transferred to milk in significant quantities (Serrano 2014).

Due to its protein nature, it is inactivated in the gastrointestinal tract, not being absorbed, so its oral bioavailability is practically nil (Serrano 2014), except in premature babies and immediate neonatal period when there may be greater intestinal permeability.

Diet, exercise and breastfeeding improve blood glucose levels.
