Explanation:

To determine the inhaled mast cell stabilizer prophylactic, we analyze each option:

• Asmanex (mometasone) is a corticosteroid, not a mast cell stabilizer.
• Cromolyn sodium is known to be an inhaled mast cell stabilizer used prophylactically (e.g., for asthma prevention).
• Xopenex (levalbuterol) is a short - acting beta - agonist for bronchodilation, not a mast cell stabilizer.
• Spiriva (tiotropium) is a long - acting anticholinergic, not a mast cell stabilizer.
