Pharmacologic Category
Sympathomimetic (Adrenergic) Agents; Selective β~2~-Adrenergic Agonists. Long-Acting β~2~-Adrenergic Agonist. (ATC-Code: R03AC12).
Mechanism of action
A long-acting, synthetic, sympathomimetic amine bronchodilator. Stimulates β~2~-adrenergic receptors, with little or no effect on α-, β~1~-, or β~3~-adrenergic receptors. Increases concentrations of cAMP. Relaxes bronchial smooth muscle, suppresses some aspects of inflammation, and stimulates airway epithelial ciliary function. Decreases airway resistance and airway reactivity to histamine. Inhibits release of proinflammatory mediators (e.g. histamine, leukotrienes C~4~ and D~4~, prostaglandin D~2~) in human lung tissue. Has little effect on heart rate.
Therapeutic use
Maintenance treatment of asthma. Prevention of bronchospasm with reversible obstructive airway disease. Prevention of exercise-induced bronchospasm. Maintenance treatment of bronchospasm associated with chronic obstructive pulmonary disease.
Pregnancy and lactiation implications
Animal studies demonstrated (dose-dependent) teratogenicity. There are no adequate studies in pregnant women. β-Agonists may interfere with uterine contractility if administered during labor. Use only if clearly needed. Enters breast milk (use with caution in nursing women).
Unlabeled use
Contraindications
Hypersensitivity to salmeterol or any component of the formulation.
Warnings and precautions
Long-acting β~2~-agonists may increase risk of asthma-related deaths. Rarely, paradoxical bronchospasm may occur with use of inhaled bronchodilating agents. Immediate hypersensitivity reactions (urticaria, angioedema, rash, bronchospasm) reported. Reports exist of laryngeal spasm, irritation, and swelling (stridor, choking) with use. Do not use for acute asthmatic symptoms. Do not initiate in significantly worsening or acutely deteriorating asthma (severe respiratory events reported). Salmeterol should only be used as adjuvant therapy in patients not adequately controlled on inhaled corticosteroids or whose disease requires two maintenance therapies. Corticosteroids should not be stopped or reduced when salmeterol is initiated. Salmeterol not a substitute for inhaled or systemic corticosteroids and should not be used as monotherapy. Use with caution in cardiovascular disease (β-agonists may cause elevation in blood pressure, heart rate and result in CNS stimulation/excitation; may also increase risk of arrhythmias). Use with caution in diabetes mellitus (may increase serum glucose). Use with caution in glaucoma (may elevate intraocular pressure). Use with caution in hepatic impairment. Use with caution in hyperthyroidism (may stimulate thyroid activity). Use with caution in hypokalemia (β~2~-agonists may decrease serum potassium). Use with caution in seizure disorders. Powder for oral inhalation contains lactose (risk of anaphylactic reactions). Salmeterol should not be used more than twice daily (do not use with other long-acting β~2~-agonists).
