Final answer:
Montelukast and anti-IgE are both used in the treatment of asthma. Montelukast blocks inflammatory substances known as leukotrienes, while anti-IgE therapy reduces levels of IgE to prevent mast cell activation.
Step-by-step explanation:
In the treatment of asthma, both Montelukast and anti-IgE play important roles. Montelukast is an antileukotriene drug, while anti-IgE refers to medications that target immunoglobulin E (IgE). Montelukast works by blocking the action of leukotrienes, which are inflammatory substances involved in asthma. On the other hand, anti-IgE therapy aims to reduce the levels of IgE in the body to prevent the activation of mast cells and the release of histamines.
