Which of the following medications acts as a mast cell stabilizer?

Cromolyn is recognized as a mast cell stabilizer due to its mechanism of action, which involves preventing the release of inflammatory mediators from mast cells. Mast cells play a crucial role in allergic reactions and asthma by releasing substances like histamines that contribute to inflammation and bronchoconstriction. By stabilizing mast cells, cromolyn helps to reduce the frequency and severity of asthma symptoms, especially in response to allergens or exercise.

In contrast, albuterol is a bronchodilator that works by stimulating beta-2 adrenergic receptors in the airways, leading to muscle relaxation and dilation of the bronchial passages. Prednisone is a corticosteroid that acts as an anti-inflammatory agent but does not stabilize mast cells. Ipratropium, an anticholinergic medication, helps to reduce bronchoconstriction by blocking the action of acetylcholine on bronchial smooth muscle, but it also does not have the mast cell-stabilizing properties of cromolyn. Thus, cromolyn is specifically effective in its role as a mast cell stabilizer in managing asthma symptoms.
