Quizplus · Accepted Answer

Diltiazem is a calcium channel blocker that works by preventing the influx of calcium ions into vascular smooth muscle. This causes relaxation of the smooth muscle and dilation of the blood vessels, improving blood flow to the heart and reducing symptoms such as chest pain in Prinzmetal's angina. It does not affect conduction through the Purkinje fibers, automaticity of the ventricular tissues, or increase oxygen consumption within the myocardial tissue.
