What does Angiotensin Converting Enzyme (ACE) Inhibitors do?
|
Inhibits conversion of angiotensin I to angiotensin II, a potent vasopressor. thereby causes vasodilation and reduction in PVR which
1) lowers blood pressure and 2) reduces preload and afterload, thereby reducing cardiac workload. Used for: HTN, CHF, MI Examples: lisinopril (Zestril), captopril (Capoten), enalapril (Vasotec) |
