What mechanism of action do mast cell stabilizers primarily use?

Mast cell stabilizers primarily act by inhibiting inflammatory cells, which is crucial in preventing the release of mediators that contribute to inflammation and allergic reactions. By stabilizing mast cells, these medications prevent the release of substances like histamine and leukotrienes, which are involved in allergic responses and asthma. This action helps to reduce the symptoms associated with these conditions, making mast cell stabilizers effective for managing allergic reactions and helping with long-term control of asthma.

The other choices represent mechanisms of action for different classes of medications. Blocking gastric acid secretion is typical for proton pump inhibitors or H2 antagonists. Relaxing airway smooth muscle is a mechanism tied to bronchodilators like beta-agonists. Decreasing bowel motility relates to medications that induce constipation or slow down gastrointestinal activity. Thus, the correct mechanism associated with mast cell stabilizers aligns with their role in inhibiting the action and effectiveness of inflammatory cells.
