Salbutamol: An Effective Bronchodilator for Asthma and Chronic Obstructive Pulmonary Disease (COPD)
Salbutamol is a widely used medication for managing asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions. It is a short-acting beta-agonist (SABA) that relaxes the bronchial smooth muscles, allowing easier breathing.
What is Salbutamol?
Salbutamol (also known as Albuterol in the U.S.) is a bronchodilator that belongs to a class of drugs called short-acting beta-agonists (SABAs). It stimulates the beta-2 adrenergic receptors in the smooth muscles of the lungs, causing the muscles to relax and the airways to dilate, making it easier to breathe. It is primarily used to treat asthma attacks and to manage symptoms of COPD.

● Chronic Obstructive Pulmonary Disease (COPD): It relieves excessive wheezing and shortness of breath in COPD patients.
