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 β2 adrenergic receptor agonist that causes relaxation of airway smooth muscle.[8] It is used to treat asthma, including asthma attacks and exercise-induced bronchoconstriction, as well as chronic obstructive pulmonary disease (COPD).[8] It may also be used to treat high blood potassium levels.[9] Salbutamol is usually used with an inhaler or nebulizer, but it is also available in a pill, liquid, and intravenous solution.[8][10] Onset of action of the inhaled version is typically within 15 minutes and lasts for two to six hours.[8]

Common side effects include shakiness, headache, fast heart rate, dizziness, and feeling anxious.[8] Serious side effects may include worsening bronchospasm, irregular heartbeat, and low blood potassium levels.[8] It can be used during pregnancy and breastfeeding, but safety is not entirely clear.[8][11]

Salbutamol was patented in 1966 in Britain and became commercially available in the UK in 1969.[12][13] It was approved for medical use in the United States in 1982.[8] It is on the World Health Organization's List of Essential Medicines.[14] Salbutamol is available as a generic medication.[8] In 2022, it was the seventh most commonly prescribed medication in the United States, with more than 59 million prescriptions.[15][16]
