Bronchodilators are medications that relax the muscles of the airways, leading to an expansion of the bronchial passages and making it easier for air to flow in and out of the lungs. These drugs are essential in the management of respiratory conditions, particularly during episodes of bronchospasm caused by diseases like asthma or chronic obstructive pulmonary disease (COPD). By widening the airways, bronchodilators help improve breathing and alleviate symptoms associated with respiratory infections and pneumonia.
