Bronchodilator (Therapeutic Class) (N/A)

Bronchodilator is a therapeutic class of drugs, not a molecular target or receptor itself. It describes any drug that causes the airways to widen, making breathing easier. This effect is achieved by various drugs acting on multiple distinct molecular targets, such as beta-2 adrenergic receptors, muscarinic acetylcholine receptors, and phosphodiesterase enzymes. Therefore, 'Bronchodilator' is a functional/pharmacological classification rather than a specific molecular entity targeted by drugs.

Other names

Airway dilator

Bronchodilators achieve their effect of airway dilation by acting on various distinct molecular targets, including beta-2 adrenergic receptors, muscarinic acetylcholine receptors (primarily M3), and phosphodiesterase enzymes. Their common mechanism is to relax the smooth muscles surrounding the airways, thereby increasing airflow.
