Amlodipine is a calcium channel blocker that acts on the cardiac muscle and its peripheral vessels. Acting on the myocardial cells‚ which are responsible for the conduction of the electric stimuli of the heart‚ Amlodipine causes a decrease of the myocardial contractility [1]. Amlodipine causes dilation of coronary and peripheral arteries which is an important treatment of hypertension‚ as well as increasing blood flow to the cardiac muscle which aids angina [2].
