Bitolterol mesylate is a beta-2-adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and COPD. Bitolterol was withdrawn from the market by Elan Pharmaceuticals in 2001. [Wikipedia] (en)

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). (en)
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.
