What is the primary mode of action for Cromolyn Sodium?

Cromolyn Sodium primarily acts by inhibiting mast cell degranulation. This is significant as mast cells play a crucial role in allergic responses and asthma. When an allergen or irritant is encountered, mast cells release mediators such as histamine, leukotrienes, and prostaglandins, which contribute to bronchoconstriction and airway inflammation. By preventing the degranulation of these mast cells, Cromolyn Sodium effectively stabilizes the cell membrane and reduces the release of these inflammatory mediators. This action helps in preventing the onset of asthma symptoms and is especially beneficial in managing exercise-induced bronchoconstriction or asthma triggered by allergens. Thus, Cromolyn Sodium is categorized as a mast cell stabilizer, making it an essential medication in the preventive management of asthma and allergic reactions.
