What is Diltiazem HCl ER 180mg?

It relaxes and widens blood vessels, which lowers blood pressure and reduces how hard the heart has to work. This helps improve blood flow and can reduce how often chest pain (angina) occurs. Diltiazem HCl ER is the generic form of Cardizem and requires a prescription from a licensed provider.

- High blood pressure (hypertension)
- Chronic stable angina (chest pain)
- Angina due to coronary artery spasm
