A) Anticholinergic agents
B) Systemic corticosteroids
C) Long-acting ?2-agonists
D) Phosphodiesterase inhibitors
Ans: B
Feedback:
A short course of systemic corticosteroids, administered orally or parenterally, may be used for treating the inflammatory reaction associated with the late-phase response. The anticholinergic agents block cholinergic receptors and reduce intrinsic vagal tone that causes bronchoconstriction. The long-acting ?2 agonists, available for administration by the inhaled or oral routes, act by relaxing bronchial smooth muscle. Theophylline, a phosphodiesterase inhibitor, is a bronchodilator that acts by relaxing bronchial smooth muscle.
