A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.
Mast cell stabilizers act on mast cells and prevent them from releasing substances that cause allergic reactions. They block a calcium channel that is important for degranulation (which occurs after exposure to specific antigens) of sensitized mast cells, and inhibits the release of histamine and slow-reacting substances of anaphylaxis. Mast cell stabilizers are used to prevent asthma attacks and the symptoms of seasonal or chronic allergic rhinitis.
