Allergic reaction is an abnormal or pathological immune response caused by tissue damage or physiological dysfunction caused by antigenic substances (such as bacteria, viruses, parasites, pollen, etc.). The drug used for the prevention and treatment of allergic diseases is an antiallergic drug, also known as an antiallergic drug. Such drugs include: 1 antihistamines, mainly histamine H1 receptor antagonists, such as promethazine, diphenhydramine, etc., can compete with histamine for histamine H1 receptor on effector cells, making histamine It cannot bind to the H1 receptor, thereby inhibiting its allergic reaction. In addition, histamine decarboxylation inhibitors and the like are also antihistamines. 2 allergic reaction medium release agent, can stabilize the mast cell membrane, prevent the release of histamine and its allergic reaction medium (such as slow-reaction substance bradykinin, etc.) to produce anti-allergic reactions, such as sodium cromoglycate. 3 other anti-allergic drugs, including calcium salts, such as calcium chloride, calcium gluconate; desensitization preparations, such as dust, sputum injection; glucocorticoids, such as prednisone.
