Salbutamol, also known as albuterol and sold under the brand name Ventolin among others, [1] is a medication that opens up the medium and large airways in the lungs. [8] It is a short-acting β 2 adrenergic receptor agonist that causes relaxation of airway smooth muscle . [ 8 ]
In some subjects, the constriction does not return to normal, and recurs after three to four hours, which may last up to a day or more. The first is named the early asthmatic response, and the latter the late asthmatic response. Bronchoconstriction can occur as a result of anaphylaxis, even when the allergen is not inhaled.

Albuterol and terbutaline gave fewer side effects, such as increased heart rate, than isoproterenol.
An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.
[3] [6] Cough medicine has little support for its use and is not recommended in children less than six years of age. [1] [11] Antibiotics should generally not be used.
