What treatments against allergies?

In support of an allergy, antihistamines are used for their antagonist of histamine, a chemical mediator release, especially during allergic reactions

How do they work?

Antihistamines are inhibitors of histamine receptors. They do not affect its production, but two types of blocking specific receptors:

– The H1-receptor, responsible for allergic reactions. H1 blocking antihistamines provide symptomatic improvement in different types of allergic reactions: hay fever, allergic rhinitis …

– H2 receptors are involved in disorders of the stomach ulcer and duodenum, and in case of gastro esophageal reflux disease. In the treatment of allergic reactions, H2 blockers have only a limited value. However, they may be indicated in the treatment of certain atopic disease such as chronic urticaria.
