This set of antiallergy medications is employed to preclude mild to moderate asthma symptoms. Leukotriene receptor antagonists, encompassing montelukast and zafirlukast, operate by obstructing the impacts of leukotrienes—natural compounds discharged in the lungs amid allergic reactions.
Leukotriene receptor antagonists do not function as bronchodilator medications and cannot provide relief during an ongoing asthma attack. Instead, they are commonly employed alongside bronchodilators and inhaled corticosteroids to decrease the occurrence of asthma attacks.
Possible adverse effects of the medications may encompass gastrointestinal disruptions and headaches. Furthermore, instances of hypersensitivity and skin reactions might also manifest.
