|Drug Class: What is Clarinex and why is it prescribed?|
|Generic Clarinex, Desloratadine is an oral, long-acting antihistamine used to relieve the symptoms of hay fever (seasonal allergic rhinitis).|
|Clarinex Mechanism: How does Clarinex work?|
Generic Clarinex, Desloratadine is a long-acting antihistamine.
Histamine is a substance in the body that stimulates the production of mucus and the dilation of blood vessels. Histamine is released from histamine-storing cells (mast cells) and attaches to other cells that have receptors for histamine. The attachment of the histamine to the receptors causes the cell to be \"activated,\" releasing other chemicals, which produce the effects that we associate with allergy. Allergy sufferers recognize histamine\'s effects as a runny nose and swollen nasal passages.
Desloratadine blocks one type of receptor for histamine (the H1 receptor); it prevents activation of cells by histamine, thereby blocking the histamine reaction.
Desloratadine does not readily enter the brain from the blood and, therefore, causes less drowsiness (sedation). It is a member of a small family of non-sedating antihistamines which includes loratadine (Claritin), cetirizine (Zyrtec), and azelastine (Astelin). Desloratadine was approved by the FDA in December, 2001
