<<|>> ANTIHISTAMINES <<|>>
An Antihistamine is an agent that serves to inhibit the release or action of histamine. Antihistamine can be used to describe any histamine antagonist, but it is usually reserved for the classical antihistamines that act upon the H1 histamine receptor.
Antihistamines are used as treatment for allergies. Allergies are caused by an excessive response of the body to allergens, such as the pollen released by grasses and trees. An allergic reaction indicates an excessive release, by the body, of histamines. Other uses of antihistamines are to help with normal symptoms of insect stings even if there is no allergic reaction.
- is not caused by an infection or allergy. The exact cause is unknown. Symptoms are triggered by something that irritates the nose, such as a dry atmosphere, air pollution, spicy foods, alcohol, strong emotions, or certain medications.
- is inflammation of the conjunctiva (the membrane covering the white part of the eye) due to allergy. Although allergens differ between patients, the most common cause is hay fever. Symptoms consist of redness (mainly due to vasodilation of the peripheral small blood vessels), oedematching and increased lacrimation (production of tears). If this is combined with rhinitis, the condition is termed
is an acute systemic (multi-system) and severe type 1 hypersensitivity allergic reaction in humans and other mammals. The term comes from the Greek words ανα
(protection). Minute amounts of allergens may cause a life-threatening anaphylactic reaction. Anaphylaxis may occur aft - is inflammation of the conjunctiva (the membrane covering the white part of the eye) due to allergy.

In common use, the term antihistamine refers only to H1 antagonists, also known as H1 antihistamines. It has been discovered that these H1-antihistamines are actually inverse agonists at the histamine H1-receptor, rather than antagonists
. Clinically, H1 antagonists are used to treat allergic reactions.
