How each medicine works
| Lisinopril — Inhibits angiotensin-converting enzyme, blocking conversion of angiotensin I to angiotensin II and suppressing the renin-angiotensin-aldosterone system. |
| Lisinopril / Hydrochlorothiazide — Lisinopril inhibits ACE, lowering angiotensin II and aldosterone; hydrochlorothiazide is a thiazide diuretic. |
| Amlodipine / Benazepril — Benazepril inhibits ACE, lowering angiotensin II and aldosterone; amlodipine is a dihydropyridine calcium channel blocker. |
| Benazepril — Benazeprilat inhibits ACE, blocking conversion of angiotensin I to angiotensin II and lowering aldosterone. |
| Enalapril — Hydrolyzed to enalaprilat, which inhibits ACE, blocking angiotensin II formation and aldosterone secretion. |
| Ramipril — Ramiprilat inhibits ACE, blocking conversion of angiotensin I to angiotensin II and reducing aldosterone. |

What each medicine is used for
| Lisinopril — Hypertension in adults and children aged 6 years and older; Adjunctive therapy for heart failure; Reduction of mortality after acute myocardial infarction in hemodynamically stable patients treated within 24 hours |

| Amlodipine / Benazepril — Hypertension not controlled on monotherapy |
| Benazepril — Hypertension in adults and children aged 6 years and older; pediatric use is not established with GFR below 30 mL/min/1.73 m² |
