Quizplus · Accepted Answer

Short-acting beta agonists, such as albuterol or salbutamol, are known as rescue medications because they are used to quickly relieve symptoms during acute asthma attacks or COPD exacerbations. They work by relaxing the muscles in the airways, allowing the lungs to open up and improve breathing. Antihistamines are used to treat allergies, maintenance medications are used for long-term control of asthma or COPD, and antitussives are used to suppress coughs.
