What medication relaxes muscle spasms in the bronchial tube?

Medications that relax muscle spasms in the bronchial tubes are known as bronchodilators. Common examples include beta-agonists like albuterol and anticholinergics like ipratropium. These medications work by relaxing the smooth muscles of the airways, leading to improved airflow and alleviation of symptoms associated with conditions like Asthma and chronic obstructive pulmonary disease (COPD).
