How Does Atrovent HFA Work?As mentioned, Atrovent HFA belongs to a group of medications known as anticholinergics or antimuscarinics. By binding to specific receptors in the airway, called muscarinic receptors, Atrovent HFA helps to relax the smooth muscle of the airway.
Atrovent HFA uses an environmentally friendly hydrofluoroalkane (HFA) propellant. This replaces the older Atrovent inhaler (which is no longer available) that contained CFCs (chlorofluoroalkanes), substances that deplete the ozone layer.
