What Is Diltiazem 30 mg?

Diltiazem 30 mg is a prescription medicine that belongs to a group of medicines called calcium channel blockers. It is mainly used to treat high blood pressure, certain heart rhythm problems, and chest pain caused by reduced blood flow to the heart.

Diltiazem works by relaxing blood vessels and affecting the movement of calcium in heart and blood vessel cells. This helps the heart work more efficiently and improves blood circulation.
