Levalbuterol hydrochloride

Levalbuterol hydrochloride is a bronchodilator used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). It is a selective beta2-adrenergic receptor agonist, which means it works by relaxing the muscles around the airways in the lungs, allowing them to open up and make it easier to breathe.

Pharmacology

Levalbuterol hydrochloride is the levorotatory isomer of the racemic drug albuterol. It is believed to provide the same bronchodilating effects as albuterol, but with fewer side effects due to its selective action. It is administered via inhalation, typically through a nebulizer or metered dose inhaler.

Clinical Use

Levalbuterol hydrochloride is used to prevent and treat wheezing, shortness of breath, coughing, and chest tightness caused by lung diseases such as asthma and COPD. It is also used to prevent bronchospasm (constriction of the airways in the lungs) during exercise.

Side Effects

Common side effects of levalbuterol hydrochloride include headache, dizziness, insomnia, dry mouth, cough, nausea, and vomiting. Serious side effects can include fast or irregular heartbeat, chest pain, and allergic reactions.
