How does this medication work? What will it do for me?
Sodium cromoglycate belongs to the class of medications called mast cell stabilizers. It is used to prevent symptoms associated with asthma that are caused by exposure to certain substances or conditions. When used regularly, this medication will decrease the occurrence and severity of asthma attacks by reducing lung inflammation.
Examples of situations causing asthma that may be prevented by sodium cromoglycate include exercise; or exposure to pollen, chemicals, allergens (substances that cause an individual to have an allergic reaction), cold air, or air pollutants.
This medication works by preventing the release of substances from certain inflammatory cells (mast cells) that cause asthma symptoms or bronchospasm. A sodium cromoglycate inhaler will not help an asthma attack that has already started.
