What is the medical term meaning an agent used to dilate bronchial tubes?

The medical term for an agent used to dilate bronchial tubes is bronchodilator. Bronchodilators are the mainstay of treatment for bronchoconstriction, a common symptom of asthma and other respiratory diseases. They work by relaxing the muscles of the airways, making it easier for air to flow in and out of the lungs. Bronchodilators can be administered through an inhaler, a nebulizer, or an oral tablet.
