An Overview of Antihistamines and their Properties used for Treatment of Different Diseases.

Background: By comparing the histamine impact to the instant response to an injected foreign protein in previously sensitized animals, one might hypothesize that histamine may be involved in this reaction. Through all four of the recognized types of histamine receptors, histamine is also essential for the control of immunological function and acute and chronic allergic inflammation.

Methods: Recent evidence points to anti-IgE antibodies and specific antibodies to cytokines like IL-4 or IL-5 that are associated with allergic inflammation as probable causes of Allergic Rhinitis.
