Asthma medications don’t work well for everyone. Asthma is a common disease that makes breathing difficult and causes coughing, wheezing, and chest tightness. People with asthma have a number of treatment options, including drugs called inhaled corticosteroids. If you have asthma, you’ve probably taken an inhaled corticosteroid or another kind of medication to treat it.
But some people still get serious asthma flare-ups despite taking their medication, or find that their asthma still interferes with everyday lives or disturbs their sleep. That’s why doctors are researching new investigational drugs that may help asthma patients in the future.
