Glycopyrronium bromide

Glycopyrronium bromide is a medication of the muscarinic anticholinergic group. It does not cross the blood–brain barrier and consequently has few to no central effects. It is given by mouth, via intravenous injection, on the skin, and via inhalation. It is a synthetic quaternary ammonium compound. The cation, which is the active moiety, is called glycopyrronium (INN) or glycopyrrolate (USAN).

It is on the World Health Organization's List of Essential Medicines.
