Briefly Introduce The Role Of Anti-allergic Drugs

- Jul 20, 2019-

Antiallergic drugs are drugs that can alleviate or eliminate allergic reactions and prevent allergic diseases. Allergic reactions are also called allergic reactions. They are tissue damage or physiological dysfunction caused by the body's antigenic substances (such as bacteria, viruses, parasites and other natural substances). They are abnormal or pathological immune reactions.

Commonly used anti-allergic drugs can be divided into 4 categories:

(1) Antihistamines mainly refer to histamine H1 receptor tinctures, such as diphenhydramine, promethazine, chlorpheniramine maleate, tripyridin, and mepyramine maleate.

(2) Adrenal corticosteroids mainly have inhibitory effects on various aspects of immune response, as well as anti-inflammatory and anti-shock effects, and are suitable for various types of allergic reactions with good curative effect. Commonly used drugs are cortisone, prednisone (prednisone), dexamethasone (flumethasone), betamethasone and the like.

(3) Adrenergic drugs can promote the production of cyclic adenosine monophosphate, and cyclic adenosine monophosphate inhibits the release of histamine and slow-reacting substances. Commonly used drugs are adrenaline, isoproterenol, norepinephrine and the like.

(4) Calcium can increase the density of capillaries, reduce permeability, reduce exudation, alleviate allergic inflammation and edema of skin and mucous membranes, and is often used as an adjuvant treatment for various types of allergic reactions. Commonly used calcium agents are calcium chloride, calcium gluconate and the like.
