Two long-acting ß 2 -adrenergic agonists (LABAs), salmeterol and formoterol, have been demonstrated to be safe and effective agents in children, both in terms of bronchodilation and prevention of exercise-induced bronchospasm. Their onsets of action differ, with formoterol having an onset similar to albuterol (3 minutes), while salmeterol has a slower onset of action (10–20 minutes). Following a single-dose administration, both agents demonstrate durations of action up to 12 hours. Following regular twice-daily administration, bronchodilation remains effective; however, a level of tolerance (or tachyphylaxis) (more…)
