Diltiazem is used to treat hypertension (high blood pressure), angina (chest pain), and certain heart rhythm disorders.
Diltiazem belongs to a family of medications known as calcium channel blockers. It works by relaxing blood vessels and by reducing the workload of the heart. This medication is used to treat high blood pressure (hypertension) and angina (chest pain).
