title: How do inhaled bronchodilators work?
abstract: 1. Beta-agonists affect bronchodilation of the airways by their action on the bronchial smooth muscles. 2. Anticholinergic drugs affect bronchodilation of the airways by blocking the effect of acetylcholine and its bronchoconstrictor action. 3. Receptors are protein molecules found in cell membranes; they can selectively bind to messenger molecules and transduce a chemical signal into a response in a target cell.
