Albuterol (also known as salbutamol) is a medication used to prevent and treat wheezing and shortness of breath caused by respiratory problems (such as asthma, and chronic obstructive pulmonary disease). It is also used to prevent exercise-induced asthma. It is an anti-inflammation medication. Albuterol belongs to the bronchodilator class of drugs. It works by relaxing the muscles surrounding the airways, allowing them to open up and allow you to breathe more easily. Controlling the symptoms of breathing problems can reduce the amount of time spent away from work or school.
