Amlo-Denk is a Dihydropyridine Calcium antagonist that inhibits the transmembrane influx of Calcium ions into cardiac and vascular smooth muscle. It has greater affinity towards vascular smooth muscle than on cardiac muscle. Amlo-Denk is peripheral vasodilator that acts directly on vascular smooth muscle to cause a reduction in peripheral vascular resistance and thereby reduces blood pressure. Amlo-Denk reduces tone, decreases coronary vasoreactivity and lowers cardiac oxygen demand by reducing after load.
