Loratadine Description :

 

Loratadine, is a long-acting, non-sedating antihistamine that is used for the treatment of allergies. Histamine is a chemical that causes many of the signs and symptoms of an allergy. Histamine is released from histamine-storing cells (mast cells) and attaches to other cells that have receptors for histamine on their surfaces. Histamine stimulates the cells to release chemicals that produce effects that we associate with allergy, including welts, itching, and tissue swelling. Loratadine(Claritin) blocks one type of histamine receptor (the H1 receptor) and thus prevents activation of cells with H1 receptors by histamine.
