A member asked:
How do short acting bronchodilators function?
A doctor has provided 1 answer
Relax smooth muscle: Saba (short acting beta-2 adrenergic agonist) work by activation of this beta-2 receptor on the smooth muscles that wrap around the small and medium airways in the lungs leading to relaxation and thus bronchodilation (opening up of narrowed airways as seen in asthma).
