Mechanism of Action
Amlodipine: Dihydropyridine calcium channel blocker; inhibits extracellular Ca ions across the membranes of myocardial cells and vascular smooth muscle cells, without changing serum calcium concentrations; this results in inhibition of cardiac and vascular smooth muscle contraction, thereby dilating the main coronary and systemic arteries
Hydrochlorothiazide: Thiazide diuretic; Inhibits Na reabsorption in distal renal tubules resulting in increased Na and water excretion; lowers blood pressure and decreases edema
