Answer:
Cromolyn
Step-by-step explanation:
Cromolyn* stabilizes mast cell membranes and thereby prevents degranulation and release of histamine. It is found in Crolom (eye drops) and Nasalcrom (nasal spray). Montelukast (Singulair) is used for seasonal allergic rhinitis in adults and children over 2 years old. It is a leukotriene receptor antagonist.
