A patient who takes cromolyn for exercise-induced bronchospasm should follow which approach for maximum therapeutic effectiveness?
A. It should be used infrequently because of systemic adverse effects.
B. One 10-mg tablet should be taken at least 2 hours before exercising.
C. It should be administered by inhalation 15 minutes before anticipated exertion.
D. It should be used as a quick-relief agent if exercise triggers asthma symptoms.
Answer: C. It should be administered by inhalation 15 minutes before anticipated exertion
Explanation: Cromolyn suppresses inflammation through inhibition of histamine release. It must be administered at least 15 minutes before exertion to prevent exercise-induced bronchospasm. It is administered by inhalation only. It is not a bronchodilator and cannot abort an ongoing attack. It is one of the safest antiasthma medications and has no systemic adverse effects.
