DRUG CLASS AND MECHANISM: Asthma is a breathing problem involving narrowing of the airways. Airways are breathing passages that allow air to move in and out of the lungs. In patients with asthma, airways can be narrowed by accumulation of mucus, spasm of the muscles that surround these airways, or swelling of the lining of the airways. Airway narrowing lead to symptoms of shortness of breath, wheezing, cough, and congestion. Medications used in treating asthma open airways are called bronchodilators. Salmeterol is a bronchodilator of the beta-2 agonist type. Beta-2 agonists are medications that stimulate beta-2 receptors on the smooth muscle cells that line the airways, causing these muscle cells to relax, thus, opening airways.
