What is Intal (Cromolyn sodium) primarily used for?

Intal, which is the brand name for Cromolyn sodium, is primarily used for preventing inflammation in the airways. This medication is classified as a mast cell stabilizer and works by inhibiting the release of inflammatory substances in response to allergens or irritants. By stabilizing mast cells, Cromolyn sodium helps to prevent the onset of asthma symptoms and bronchospasms, making it effective in managing asthma when used on a regular basis.

The reason this use is crucial is that controlling airway inflammation can significantly reduce the frequency and severity of asthma attacks, allowing patients to maintain better overall respiratory health. This preventative approach is particularly important for individuals with allergic or exercise-induced asthma, as it helps to manage their condition proactively.

The other options do not align with the primary function of Cromolyn sodium. For instance, it is not used to treat acute asthma attacks because it does not provide immediate relief; instead, quick-relief medications like albuterol are aimed at treating sudden symptoms. Similarly, while it may indirectly contribute to overall lung function by reducing inflammation over time, its primary action is not to enhance lung function directly or to promote sleep in patients with asthma.
