about fexofenadine -second generation h1 antagonist antihistamine. - -mechanism of action of fexofenadine -fexofenadine blocks one type of peripheral receptor for histamine (the h1 receptor) and thus prevents activation of h1 receptor-containing cells by histamine (histamine is released from histamine-storing cells (mast cells) and then 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 that produce the effects that we associate with allergy e.g. sneezing.) and the allergic symptoms produced by it.
