bronchoconstrictor
Airway narrowing agent
A bronchoconstrictor is a substance that narrows the airways in the lungs by causing the bronchial muscles to contract.
Histamine and certain drugs act as bronchoconstrictors, triggering breathing difficulties in conditions like asthma.
The opposite is a bronchodilator, which opens the airways.
