Long-acting beta agonists
Long-Acting Beta Agonists
Long-Acting Beta Agonists (LABAs), pronounced as /lɒŋ ˈæktɪŋ ˈbiːtə əˈɡɒnɪsts/, are a type of Bronchodilator medication that is used to manage Asthma and Chronic Obstructive Pulmonary Disease (COPD). The term originates from the Greek words "longus" meaning long, "actio" meaning action, "beta" referring to the second letter of the Greek alphabet, and "agonistes" meaning competitor.
LABAs work by relaxing the muscles around the airways in the lungs, allowing them to open up and make it easier for air to get in and out. They are called "long-acting" because they work for a longer period of time, typically 12 hours or more.
Usage
LABAs are often used in combination with other medications, such as Inhaled Corticosteroids, to control and prevent symptoms of asthma and COPD. They are not used for immediate relief of symptoms.
Examples
Examples of LABAs include Salmeterol, Formoterol, and Indacaterol. These medications are usually taken through an inhaler or nebulizer.
Side Effects
Possible side effects of LABAs can include increased heart rate, nervousness, and trouble sleeping. It is important to discuss these potential side effects with a healthcare provider before starting treatment.
