This leads to vasodilation and decreased blood pressure. ACE inhibitors also have protective effects on the heart and kidneys (Mills et al., 2018). Beta-Blockers: These medications reduce the heart rate and the force of contraction, leading to lower blood pressure. Beta-blockers are particularly beneficial in patients with concomitant heart failure or those who have experienced myocardial infarction (Carey et al., 2018). Calcium Channel Blockers: These drugs inhibit calcium ions from entering cardiac and smooth muscle cells, causing vasodilation and reduced blood pressure. They are especially useful in patients who do not tolerate ACE inhibitors or beta-blockers (Pinho-Gomes and Rahimi, 2019). Diuretics: Diuretics help to eliminate excess sodium and water from the body, reducing blood volume and blood pressure. Thiazide diuretics are commonly used and have been shown to reduce cardiovascular events in hypertensive patients (Benenson and Bradshaw, 2021). 4.1.2 Effectiveness of combination therapies Combination therapies, which involve using multiple antihypertensive agents from different classes, are often more effective than monotherapy in controlling blood pressure. The rationale behind combination therapy is to target different mechanisms involved in blood pressure regulation, thus achieving a more comprehensive and effective reduction in blood pressure. Studies have shown that combination therapy can more effectively lower blood pressure compared to monotherapy, which is particularly important for patients with severe or resistant hypertension (Rea et al., 2018). Additionally, combination therapy has been associated with a lower risk of cardiovascular events, such as heart attack and stroke, due to the synergistic effects of different drug classes working together to provide more robust cardiovascular protection (Tasic et al., 2020). Fixed-dose combinations (FDCs) simplify treatment regimens by combining two or more antihypertensive agents into a single pill, improving patient adherence to the treatment plan by reducing the pill burden and simplifying dosing schedules. Specific combination therapies include combining an ACE inhibitor with a diuretic, which can enhance blood pressure reduction and mitigate the potassium-wasting effect of diuretics. Another effective combination is a beta-blocker with a diuretic, particularly beneficial in patients with concomitant conditions such as heart failure or ischemic heart disease. Combining a calcium channel blocker with an ACE inhibitor is particularly useful in patients with high cardiovascular risk, providing effective blood pressure control and vascular protection. For patients with resistant hypertension, the addition of mineralocorticoid receptor antagonists (MRAs) such as spironolactone or eplerenone can be beneficial. These drugs block the effects of aldosterone, reducing sodium retention and blood pressure. MRAs have been shown to be effective in patients who do not achieve adequate blood pressure control with other medications (Carey et al., 2018). While pharmacological interventions are effective, they can also be associated with adverse effects. Common side effects include electrolyte imbalances, renal impairment, and orthostatic hypotension. It is essential to monitor patients regularly to adjust dosages and manage any adverse effects promptly (Pinho-Gomes and Rahimi, 2019). Patient education and regular follow-up are crucial components of successful long-term pharmacological management. 4.2 Non-pharmacological interventions 4.2.1 Lifestyle modifications Lifestyle modifications are a critical component of managing HHD. These include dietary changes, regular physical activity, smoking cessation, and weight management. The DASH (Dietary Approaches to Stop Hypertension) diet, which is rich in fruits, vegetables, and low-fat dairy products while low in saturated fats and cholesterol, has been proven effective in lowering blood pressure (Valenzuela et al., 2020). Regular physical activity, such as brisk walking for 30 minutes most days of the week, can also significantly reduce blood pressure and improve cardiovascular health (Tjahjono and Pramudya, 2023).
