Beta2 Agonists

Beta2 agonists are medications that help open up the airways in the lungs by stimulating specific receptors called beta2 receptors. This results in relaxed smooth muscles, making breathing easier for people with conditions like asthma or chronic obstructive pulmonary disease (COPD). They act quickly to relieve symptoms such as wheezing, shortness of breath, and chest tightness. Common examples include albuterol and salmeterol. These drugs are typically inhaled for rapid relief or long-term control, improving airflow and reducing respiratory discomfort during episodes of airway constriction.
