Leukotriene Modifiers

Leukotriene modifiers (leukotriene antagonists) are medications used to treat allergic rhinitis symptoms and prevent asthma symptoms.

Leukotrienes are chemicals the body releases when the immune system senses an allergen. These inflammatory chemicals cause the airways in the lungs to tighten as well as cause the production of excess mucus and fluid.
