What is Diltiazem used for?
Diltiazem is a calcium channel blocker prescribed to treat high blood pressure (hypertension), chest pain (angina), and certain heart rhythm disorders (arrhythmias) [1][3]. It works by relaxing blood vessels, which lowers blood pressure and reduces the heart's workload [3].
