In managing this patient's hypertension, what is the primary mechanism by which amlodipine and lisinopril work together to control blood pressure?
Amlodipine reduces peripheral vascular resistance, while lisinopril decreases angiotensin II production, leading to vasodilation. Amlodipine blocks aldosterone receptors, while lisinopril increases sodium excretion, reducing blood volume. Amlodipine increases cardiac output, while lisinopril reduces heart rate, synergistically lowering blood pressure. Amlodipine decreases renin secretion, while lisinopril inhibits calcium influx into smooth muscle cells, causing vasodilation.
