How do inhalers work?
Asthma inhalers work by relaxing the muscles wrapped around the airway (of the patient) when they are inappropriately contracted (this condition is called bronchospasm , i.e., tightening of the muscles that line the airways). During an asthma attack/crisis, the airways in the lungs get so tight they almost shut off.
