What Are the Risks of Using Inhaled Long-Acting Beta-Agonist Medications for the Relief of Asthma?
Asthma is a disease that is usually caused by inflammation of the bronchial tubes. Inflammation makes the muscle cells that surround the bronchial tubes tighten up and narrow the bronchial air passages, making it difficult for an asthmatic person to breathe. A type of inhaled medicine known as long-acting beta-agonists provides prolonged (12 hours) bronchial muscle relaxation. Some studies have suggested that even though long-acting beta-agonists provide symptomatic relief for asthmatic patients, they can be harmful with long-term use.
