Mechanism of action

Formoterol activates beta-2 adrenergic receptors on bronchial smooth muscle cells, triggering a cascade that increases intracellular cAMP levels, leading to smooth muscle relaxation and airway dilation. As a long-acting formulation, it provides sustained bronchodilation for 12 hours or longer, making it suitable for maintenance therapy in chronic obstructive airway diseases. The inhalation solution formulation allows direct delivery to the lungs for rapid local effect.
