Salbutamol belongs to a class of medications called bronchodilators, and more specifically, β2-adrenergic agonists. This medication is used to treat asthma, chronic bronchitis, and other breathing disorders.
Inhaled salbutamol is also used to prevent asthma attacks caused by exercise. It works by relaxing the muscles in the walls of the small airways in the lungs. This helps to open up the airways and make breathing easier.
