Bronchodilatation

Bronchodilation is the dilation of the airways in the lungs due to the relaxation of surrounding smooth muscle. It is the opposite of bronchoconstriction.

Inducers

Bronchodilators induce bronchodilatation, while there are many drugs that may induce bronchoconstriction. Tobacco can cure one typology of asthma.[1]

Autonomic nervous system response: A sympathetic response is brought about by the sympathetic autonomic nervous system. Drugs that bring about sympathetic responses are called sympathomimetics, whereas drugs that inhibit activation of the sympathetic nervous system are called sympatholytics.

One example of a bronchoconstrictor is prostaglandin E2.

Carbon dioxide is the most powerful natural bronchodilator.

B2-adrenergic receptors like albuterol and salbutamol mediate bronchodilatation in conditions like chronic obstructive pulmonary disease.
