A patient is bothered with nighttime episodes of bronchoconstriction related to asthma. Which of the following medications can be administered to decrease the nighttime episodes and prevent asthma attacks?
A) Xanthines
B) Beta2-adrenergic agonists
C) Anticholinergics
D) Leukotriene modifiers
D
Feedback:
The leukotriene modifiers improve symptoms and pulmonary function tests, decrease nighttime symptoms, and decrease the use of beta2-adrenergic drugs. Xanthines treat acute attacks but do not prevent asthma from occurring. Beta2-adrenergic agonists treat acute attacks but do not prevent asthma from occurring. Anticholinergics block the action of acetylcholine in bronchial smooth muscle when given by inhalation.
