Its bromide salt is used as a drug for the treatment asthma and chronic obstructive pulmonary disease. It has a role as a muscarinic antagonist, an anti-asthmatic drug and an antispasmodic drug. It is a carboxylic ester, a quaternary ammonium ion, a tertiary alcohol, an azabicycloalkane and an organofluorine compound."}]
