In the last two issues I had discussed the use of short and long acting adrenergic bronchodilators.
The most common clinically observed side effects of adrenergic bronchodilators are tremor, tachycardia, tolerance to bronchodilator effect, loss of bron-choprotection, nervousness, worsening ventilation to perfusion ratio, hypokalemia, and sensitivity to additives and propellants.
Commonly reported side effects of the adrenergic bronchodilators include headache, nervousness, irritability anxiety, and insomnia, which are caused by central nervous system stimulation.
The action of salmeterol in providing sustained protection from bronchoconstriction differs to a degree from that of the previously described adrenergic bronchodilators.
This article will review long acting adrenergic bronchodilator agents available and their indication for use.
