Quick-relief medicines are a type of asthma medicine that works quickly. They "rescue"
the person from wheezing, coughing, and shortness of breath.
Most of these medicines are inhaled and work by relaxing the muscle around
the airways. When the muscles are relaxed, the airways are wider, which makes it easier
to move air in and out of the lungs.
But quick-relief medicines won't prevent future asthma flare-ups and may not be enough to keep someone's asthma
under control. Long-term control
medicine, taken daily, is often needed to keep the airways from getting swollen
and narrow in the first place.
