Carbuterol

Carbuterol is a bronchodilator and a beta-2 adrenergic receptor agonist. It is used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). Carbuterol is not currently approved for use in the United States, but is available in other countries.

Mechanism of Action

Carbuterol works by stimulating beta-2 adrenergic receptors in the lungs, which causes the muscles in the airways to relax. This opens up the airways and makes it easier to breathe.

Uses

Carbuterol is used to treat conditions that cause narrowing of the airways, such as asthma and COPD. It can also be used to prevent exercise-induced bronchospasm.

Side Effects

Common side effects of carbuterol include palpitations, tremor, and nervousness. Less common side effects include hypokalemia, hyperglycemia, and tachycardia.

Contraindications

Carbuterol should not be used in patients with a history of hypersensitivity to the drug or any of its components. It is also contraindicated in patients with tachyarrhythmia.
