Mechanism and action
Evista: Raloxifene binds estrogen receptors and produces tissue-selective effects: estrogen-agonist activity in bone (preserving bone mineral density) and on lipid metabolism (lowering LDL cholesterol), while exhibiting estrogen… Zyrtec: Cetirizine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine released by mast cells during allergic responses.
