Immune System (Elicitation of Allergic Response)

The immune system's role in the elicitation of allergic responses centers on its overreaction to harmless substances, known as allergens. In individuals with allergies, the immune system mistakenly identifies these substances—such as pollen, dust mites, or certain foods—as threats and mounts a defensive response that leads to characteristic allergy symptoms. This process involves sensitization to the allergen, followed by an effector phase where re-exposure triggers mast cell and basophil degranulation, leading to the release of inflammatory mediators.

Varies depending on the drug; examples include histamine receptor antagonism, suppression of inflammation, IgE neutralization, etc.
