Description: Terbutaline is a selective β-2-adrenoceptor agonist. At therapeutic doses it acts on the β- 2-adrenoreceptors of bronchial muscle with little or no action on the α1-adrenoreceptors of cardiac muscle. Terbutaline stimulates the production of intracellular cyclic-AMP, enhancing the binding of intracellular calcium to the cell membrane and endoplasmic reticulum, resulting in bronchodilation. It also […]
