Salbutamol (Albuterol) is a β2-agonist bronchodilator drug used for asthma in humans.

This drug was used for cases of bronchitis and pulmonary interstitial fibrosis, but reduced efficacy of bronchodilation compared with humans[1] (improved expiratory airflow, but no effect on PaO2)[2] and untoward side-effects resulted in treatment regimens changing to alternative inhalants which contains corticosteroids[3].

Toxicity associated with accidental ingestion has been reported in dogs, resulting in mydriasis, paresis, ventricular tachycardia[4], hyperactivity and hypokalemia[5].

Treatment usually requires intravenous fluid administration with supplemental potassium chloride[6].
