When considering options for treating hypertension and angina, compare diltiazem ER to other common medications based on efficacy, side effects, and dosing convenience:
| Medication | Use case | Side effect risk | Cost (generic) | Administration |
| Diltiazem ER (CCB Non-DHP) | Hypertension, stable angina | Moderate (bradycardia, edema) | Low–moderate | Oral, once‑daily |
| Amlodipine (CCB-DHP) | Hypertension, stable angina | Edema | Low | Oral, once‑daily |
| Lisinopril (ACE inhibitor) | Hypertension, heart failure support | Cough, hyperkalemia | Low | Oral, once‑daily |
| Metoprolol (BB) | Hypertension, angina, arrhythmia | Fatigue, bradycardia | Low–moderate | Oral, once‑daily |
Diltiazem ER offers effective control of blood pressure and angina with once-daily dosing. It may cause slow heart rate or swelling. Amlodipine is similar but can cause more fluid retention. Lisinopril doesn’t affect heart rate but may cause cough. Metoprolol is useful in arrhythmias but requires careful dosing due to fatigue risk.
