INTAL, also known by its generic name Cromolyn Sodium, is a medication primarily used in the management and prevention of asthma and allergic reactions. It functions as a mast cell stabilizer, which means it works by preventing the release of substances in the body that cause inflammation and allergic symptoms. INTAL is often administered through inhalation, allowing direct action on the airways to prevent asthma attacks and breathing difficulties. It may also be used in the form of eye drops for allergic conjunctivitis or a nasal spray for allergic rhinitis. While INTAL is effective in managing symptoms, it is not a rescue medication for acute asthma attacks but rather is used for long-term control and prevention.
