Atrovent, also called Ipratropium, is a bronchodilator that is taken by inhalation to help control the symptoms of lung diseases, such as asthma, chronic bronchitis, and emphysema. Atrovent helps decrease coughing, wheezing, shortness of breath, and troubled breathing by increasing the flow of air into the lungs. When Atrovent is used to treat acute, severe attacks of asthma, bronchitis, or emphysema, it is used only in combination with other bronchodilators.

The active ingredient in Atrovent (ipratropium bromide) is ipratropium bromide monohydrate. It is an anticholinergic bronchodilator chemically described as 8-azoniabicyclo(3.2.1)-octane,3- (3-hydroxy-1-oxo-2-phenylpropoxy)-8-methyl-8-(1-methylethyl) -,bromide, monohydrate(endo, syn)-, (±)-; a synthetic quaternary ammonium compound, chemically related to atropine.Ipratropium bromide is a white to off-white crystalline substance, freely soluble in water and lower alcohols. It is a quaternary ammonium compound and thus exists in an ionized state in aqueous solutions. It is relatively insoluble in non-polar media.
The structural formula is:
