Generic Information

Generic name



Inhaled Salmeterol exerts a significant bronchodilating effect within 10 to 20 minutes of single-dose administration with asthma and this effect lasts for up to 12 hours or more. Salmeterol has a beneficial effect on airway mucociliary clearance that will reduce the incidence of respiratory tract infections. Salmeterol produces a significant protective effect against Exercise Induced Asthma (EIA) for up to 9 to 12 hours in both adolescents and adults. Salmeterol improves the overnight PEFR (Peak Expiratory Flow Rate) and controls the symptoms of the patients with nocturnal asthma. The use of Salmeterol avoids exposure of children to theophylline or high-dose corticosteroid, with their attendants risks. Addition of Salmeterol to inhaled corticosteroid therapy is significantly more effective in terms of an improvement in lung function, symptom control and a reduction in the use of rescue bronchodilator therapy (use of short acting beta2-agonist). Addition of Salmeterol to inhaled corticosteroid therapy also significantly reduces the use of inhaled corticosteroids

Therapeutic Class

Long-acting selective 8-adrenoceptor stimulants


Salmeterol stimulates intracellular adenyl cyclase, the enzyme that catalyses the conversion of ATP to cyclic-3',5'-adenosine monophosphate (cAMP) resulting in relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from mast cells.

Dosage & Administration

Inhalation/Respiratory- Chronic asthma: Adult: As metered dose aerosol or dry powder inhaler: 50 mcg bid, or up to 100 mcg bid if necessary, in asthma patients with more severe airways obstruction. Child: 4-12 yr 50 mcg bid. Prophylaxis of exercise-induced asthma: Adult: As metered dose aerosol or dry powd inhaler: 50 mcg at least 30 min prior to exercise. Child: 84 yr Same as adult dose. Chronic obstructive pulmonary disease: Adult: As metered dose aerosol or dry powder inhaler: 50 mcg bid.


As with all the other beta2-agonists there may be interaction with betablocking agents at the receptor site when given concomitantly. Monoamino Oxidase Inhibitors and Tricyclic Antidepressants : These agent should be used with caution because Salmeterol may be potentiated by these agents.


Monotherapy in the treatment of asthma. Treatment of status asthmaticus, other acute episodes of asthma or COPD.

Drugs should be given only if the potential benefit justifies the potential risk to the foetus.
