Diltiazem is classified as a calcium channel blocker, which works by blocking the influx of calcium into cells of the heart and blood vessels. This results in relaxation of the smooth muscles of the blood vessels, reducing blood pressure and improving blood flow to the heart. It is used primarily in the treatment of hypertension, angina, and certain arrhythmias.
