Mechanisms compared
Norvasc: Amlodipine selectively blocks L-type calcium channels in vascular smooth muscle, reducing transmembrane calcium influx and producing peripheral arterial vasodilation. Fexofenadine: Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle.
