Comprehensive Drug Guide
How Does Formoterol Fumarate Work?
Formoterol Fumarate works by stimulating beta-2 adrenergic receptors in the smooth muscle of the airways. This stimulation causes the muscles to relax, leading to bronchodilation. The relaxation of the airways helps to improve airflow and reduce symptoms such as wheezing and shortness of breath.
