Beta2 Agonists

Bronchodilators are an important component of treatment in respiratory failure caused by obstructive lung disease. These agents act to decrease muscle tone in both small and large airways in the lungs. This category includes beta-adrenergics, methylxanthines, and anticholinergics.

Terbutaline (Brethaire, Bricanyl)

Terbutaline acts directly on beta2 receptors to relax bronchial smooth muscle, relieving bronchospasm and reducing airway resistance.

Albuterol (Proventil)

Albuterol is a beta-agonist useful in the treatment of bronchospasm. It selectively stimulates beta2-adrenergic receptors of the lungs. Bronchodilation results from relaxation of bronchial smooth muscle, which relieves bronchospasm and reduces airway resistance.
