Question: 1 / 400

Which class of drugs includes montelukast and zafirlukast?

Betablockers

Corticosteroids

Leukotriene receptor antagonists

Montelukast and zafirlukast are both examples of leukotriene receptor antagonists, which are used to treat asthma and other respiratory conditions. This class of drugs works by blocking the action of leukotrienes, which are molecules that contribute to inflammation and constriction of airways. Betablockers and anticholinergics are both classes of medications that are used to treat different conditions, such as high blood pressure and chronic obstructive pulmonary disease (COPD). Corticosteroids, on the other hand, are a type of medication that is used to treat a wide range of conditions, including asthma, allergies, and autoimmune disorders. They work by reducing inflammation and suppressing the immune system. Therefore, neither of these options are correct when identifying the class of drugs that includes montelukast and zafirlukast.
