Pharmacology
Indication Used to dilate air passages in the lungs that have become narrowed as a result of disease or inflammation. It is used in the treatment of asthma and chronic obstructive pulmonary disease (COPD).
Mechanism of action Bitolterol is an adrenergic beta-2 agonist. Asthma results from a narrowing of the bronchial tubes. This narrowing is caused by muscle spasm and inflammation within the bronchial tubes. Agonism of the beta-2 adrenergic receptors by bitolterol leads to a relaxation of the smooth muscles surrounding these airway tubes which then increases the diameter and ease of air flow through the tubes.
