(brong″kō-dī-lāt′ŏr) [broncho- + dilator] A drug that expands the bronchi by relaxing bronchial muscle. There are three classes of bronchodilators: beta2 adrenergic-receptor agonists, methylxanthines, and anticholinergic agents. The beta2 adrenergic-receptor agonists produce the greatest bronchodilation in patients with bronchial asthma. The beta2 adrenergic-receptor agonists are the best drugs for patients with mild, intermittent asthma and for acute attacks of reactive airway disease. SEE: table.
