Given the patient's current medication regimen for hypertension, which rationale best explains the use of both lisinopril and amlodipine?
Using both lisinopril and amlodipine is aimed at reducing the risk of osteoporosis, as they both have bone-protective effects. The combination of lisinopril and amlodipine is primarily to counteract the side effects of hydrochlorothiazide, such as hypokalemia. Both lisinopril and amlodipine are used together to specifically treat stress-related hypertension, given the patient's stress finding. Combining lisinopril and amlodipine targets different mechanisms to manage hypertension effectively, addressing both vasoconstriction and fluid retention.
