Anticholinergic drug used as spasmolytic for functional gastrointestinal disorders. At latest update relevant published data on excretion into breast milk were not found. It acts locally on the intestinal mucosa. Absorption through the intestine is practically absent (Evangelista 2004, Catalogo 2008), with an excretion being almost 100% unmodified in feces that is determinant for the extremely low levels reached in the plasma (Zhao 2010: <0.02 mg / L), which causes the passage through breastmilk in significant amounts must be very unlikely.Side effects are mild and very rarely seen. Although anticholinergics may reduce milk production, however, because of its poor absorption it would not be the case with Otilonium.
