Albuterol (Salbutamol) (Asthalin (4 mg)) is a short-acting β2-adrenergic receptor agonist, used to prevent and treat wheezing, shortness of breath, coughing, and chest tightness caused by lung diseases such as asthma and chronic obstructive pulmonary disease (COPD); a group of diseases that affect the lungs and airways. It relaxes the smooth muscles in the airway, which allows air to flow in and out of the lungs more easily.
