A 30-year-old male patient comes into the emergency department with severe asthma-related signs and symptoms. What medication is recommended to prevent the signs and symptoms of asthma?
A) Diphenhydramine (Benadryl)
B) Zafirlukast (Accolate)
C) Albuterol sulfate (Ventolin)
D) Epinephrine
Ans: B
Feedback: Many manifestations of inflammation can be attributed in part to leukotrienes. Medications categorized as leukotriene antagonists or modifiers such as zafirlukast (Accolate) block the synthesis or action of leukotrienes and prevent signs and symptoms associated with asthma. Albuterol sulfate relaxes smooth muscle during an asthma attack. Diphenhydramine prevents histamine's effect on smooth muscle. Epinephrine relaxes bronchial smooth muscle.
