BRONCHODILATOR Meaning and
Definition
-
A bronchodilator is a medication or substance that helps to relax and widen the airways in the lungs, specifically the bronchi and bronchioles. It is mainly used in the treatment of various respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and bronchitis.
Bronchodilators work by targeting and relaxing the smooth muscles that line the airways in the lungs. This action helps to open up the narrowed or constricted air passages, allowing air to flow more freely in and out of the lungs. As a result, symptoms like shortness of breath, wheezing, coughing, and chest tightness are alleviated.
There are different types of bronchodilators available, including beta-agonists, anticholinergics, and methylxanthines. Beta-agonists such as albuterol and salmeterol stimulate receptors in the airways, causing the muscles to relax. Anticholinergics, such as ipratropium, block the action of a chemical called acetylcholine, which can cause bronchoconstriction. Methylxanthines like theophylline inhibit enzymes that constrict the airways.
Bronchodilators can be administered through various methods, including inhalers, nebulizers, pills, or injections. Inhalation is the most common route as it allows for direct delivery of the medication to the lungs.
It is important to note that bronchodilators provide temporary relief and are typically used in conjunction with other medications to manage respiratory conditions effectively. Additionally, the use of bronchodilators should be done under the guidance and prescription of a healthcare professional to ensure safe and appropriate usage.

Common Misspellings for BRONCHODILATOR
Etymology of BRONCHODILATOR
The word "bronchodilator" is derived from two root words: "broncho" and "dilator".
The word "broncho" is derived from the Greek word "bronkhos", which means "windpipe" or "bronchial tubes". It is used to refer to the air passages in the respiratory system.
The word "dilator" comes from the Latin word "dilatus", which means "to spread out" or "to open wide". It is used to describe something that causes expansion or widening.
Therefore, "bronchodilator" combines these two roots to describe a substance or medication that widens or enlarges the bronchial tubes, thereby easing breathing and relieving symptoms of bronchial constriction, such as asthma or chronic obstructive pulmonary disease (COPD).
