Pseudoallergy: Applications, Mechanism & Signs and symptoms

Pseudoallergy, sometimes known as nonallergic hypersensitivity, is a type of hypersensitivity reaction mostly described in the context of drug allergy. The mechanism is somewhat similar to the type 1 hypersensitivity in the Gell and Coombs classification in that the effector cell is also mast cell. In pseudoallergic reaction, the mast cell is directly…
