Bronchodilatation, or bronchodilation, is a reduction in airway resistance caused by the relaxation of airway smooth muscle. It is the opposite of bronchoconstriction.[1][2]
Medically, bronchodilatation is used in the treatment of certain respiratory disorders, where it can reduce respiratory symptoms and/or improve lung function. Pharmacologically, bronchodilatation is achieved via bronchodilators.[1][2]
