What does albuterol mean?
Albuterol is a widely used medication belonging to a class of drugs called short-acting beta-2 adrenergic agonists. It works by relaxing the smooth muscles that line the airways, rapidly opening constricted breathing passages during episodes of bronchospasm. Physicians prescribe it most often for asthma and chronic obstructive pulmonary disease, typically delivered through a handheld metered-dose inhaler or a nebulizer that turns the liquid drug into a fine mist. Because it acts within minutes, it serves as a 'rescue' medicine for sudden symptoms such as wheezing, coughing, chest tightness, and shortness of breath, though it does not treat the underlying inflammation that causes chronic airway disease. In the United States the drug is officially named albuterol, while most of the rest of the world knows it by its international nonproprietary name, salbutamol — chemically identical medicines carrying different labels depending on geography.
nounA short-acting beta-2 adrenergic agonist used as a bronchodilator to relieve bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease (COPD); known as salbutamol outside the United States.
- A short-acting bronchodilator drug (a beta-2 agonist) used to treat or prevent bronchospasm in asthma, COPD, and other respiratory conditions.
"The doctor prescribed an albuterol inhaler to open her airways during asthma attacks."
"She carried her albuterol inhaler everywhere in case an asthma attack struck without warning."
"The emergency room nurse administered albuterol through a nebulizer to ease the patient's wheezing."
The same life-saving puff of medicine has two names: Americans call it albuterol, while nearly everyone else on Earth calls it salbutamol.

Etymology of albuterol
Albuterol was developed in the late 1960s by researchers at Allen & Hanburys in Britain, where it was introduced under the name salbutamol; the American adopted name 'albuterol' was constructed to avoid confusion with adrenaline-like compounds, combining elements referencing its chemical structure — including the '-ol' suffix denoting an alcohol group, a naming pattern shared with compounds such as ethanol and propanol. It entered widespread clinical use in the 1970s as one of the first selective beta-2 agonists.
How albuterol is actually used
Albuterol is a technical/medical term, encountered mainly in clinical, pharmaceutical, and patient-instruction contexts rather than everyday conversation. It is the official United States Adopted Name (USAN); British and most international sources use 'salbutamol' instead, so writers should match the convention of their audience.
Easily confused with albuterol
Salbutamol is the international nonproprietary name for the same drug that is marketed in the United States under the name albuterol.
