Clarinex and its Uses
Generic Clarinex is in a class of medications called antihistamines. Clarinex is a non-sedating antihistamine.
Generic Clarinex is used to relieve hay fever and allergy symptoms (sneezing, runny nose, and itchy, watery eyes),, including sneezing; runny nose; and red, itchy, tearing eyes. Clarinex is also used to treat hives and associated itching of the skin.
Generic Clarinex works by blocking histamine, a substance in the body that causes allergic symptoms. Clarinex may cause less drowsiness than other antihistamines.
|| Top || Working Mechanism of Clarinex
Generic Clarinex works by preventing the actions of histamine.
Histamine is a substance produced by the body as part of its defence mechanisms. It is stored in cells called mast cells, in almost all tissues of the body. When the body reacts to a foreign substance (known as an allergen, eg flower pollen, dust mites), the mast cells stimulated by the allergen release their stores of histamine.
The released histamine then binds to its receptors (H-1 receptors), causing a chain reaction that results in allergic symptoms. It causes an increase in blood flow to the area of the allergy, and the release of other chemicals that add to the allergic response.
All this results in the symptoms of an allergic reaction. In hayfever and other nasal allergies (allergic rhinitis), histamine causes inflammation of the nose, eyes, skin or airways and results in itchy watery eyes, a runny nose, sneezing and nasal congestion.
Generic Clarinex works by blocking histamine receptors. It does not prevent the actual release of histamine from mast cells, but prevents it binding to its receptors. This in turn prevents the release of other allergy chemicals and increased blood supply to the area, and provides relief from the typical symptoms of nasal allergies such as hayfever.
