Summary
10 papers analyzed
These studies suggest that various antihypertensive medications, including thiazides, beta-blockers, ACE inhibitors, and calcium channel blockers, are effective in reducing mortality and cardiovascular events, with combination therapies often being more effective and tolerable than monotherapies, and that treatment benefits and risks may vary by age, disease severity, and specific patient conditions.

Hypertension Medications: Efficacy and Safety
First-Line Antihypertensive Drugs: Thiazides, Beta-Blockers, ACE Inhibitors, and Calcium Channel Blockers
Thiazide Diuretics
Thiazide diuretics, particularly at low doses, are highly effective as first-line treatments for hypertension. They significantly reduce mortality, stroke, coronary heart disease (CHD), and total cardiovascular events (CVS) compared to placebo or no treatment. Low-dose thiazides have been shown to reduce mortality by 11%, total CVS by 30%, stroke by 32%, and CHD by 28% . However, high-dose thiazides, while effective in reducing stroke and total CVS, do not significantly impact mortality or CHD.
Beta-Blockers
Beta-blockers, another common first-line treatment, show mixed results. They do not significantly reduce mortality or CHD but are effective in reducing stroke and total CVS. However, beta-blockers are associated with a higher rate of withdrawals due to adverse effects compared to thiazides.
ACE Inhibitors
ACE inhibitors are effective in reducing mortality, stroke, CHD, and total CVS. They reduce mortality by 17%, stroke by 35%, CHD by 19%, and total CVS by 24%. Despite their efficacy, the evidence supporting ACE inhibitors is considered to be of lower quality compared to thiazides.
Calcium Channel Blockers
Calcium channel blockers reduce stroke and total CVS but do not significantly impact mortality or CHD. They are associated with a lower rate of adverse effects compared to beta-blockers and high-dose thiazides.
Dual Combination Therapy vs. Monotherapy
Efficacy and Safety
Dual combination therapy, involving two antihypertensive drugs at low-to-standard doses, is more effective than monotherapy in reducing systolic blood pressure (SBP) and improving blood pressure control. This approach shows a dose-response relationship, with higher efficacy observed at higher doses of the combination therapy. Importantly, dual combination therapy does not significantly increase the rate of withdrawals due to adverse events compared to monotherapy.
Hypertension Management in Older Adults
Blood Pressure Targets
For adults aged 60 years or older, treating hypertension to achieve a systolic blood pressure (SBP) target of less than 150 mm Hg is beneficial. This approach reduces all-cause mortality, stroke, and cardiac events. However, targeting an SBP of less than 140 mm Hg does not show significant additional benefits in reducing mortality or cardiac events compared to the higher target.
Antihypertensive Drug Classes
In older adults, thiazide diuretics are particularly effective. They reduce all-cause mortality, cardiovascular morbidity and mortality, cerebrovascular morbidity and mortality, and coronary heart disease morbidity and mortality . The benefits are most pronounced in individuals aged 60 to 79 years, with a significant reduction in all-cause mortality observed in this age group.
Hypertension During Pregnancy
Antihypertensive Drug Therapy
For pregnant women with mild to moderate hypertension, antihypertensive drugs halve the risk of developing severe hypertension but do not significantly impact the risk of pre-eclampsia, preterm birth, or neonatal outcomes. Beta-blockers are more effective than methyldopa in reducing the risk of severe hypertension during pregnancy.
Innovative Treatment Strategies
Quadruple Combination Therapy
A novel approach involving a single pill containing ultra-low doses of four antihypertensive drugs (quadpill) has shown promising results. This strategy is more effective in lowering blood pressure and achieving blood pressure control compared to standard-dose monotherapy. The quadpill approach maintains its efficacy over the long term and is well-tolerated, with no significant increase in adverse event-related treatment withdrawals.
Conclusion
Thiazide diuretics, particularly at low doses, remain the most effective first-line treatment for hypertension, reducing mortality and cardiovascular events. ACE inhibitors and calcium channel blockers are also effective but with lower quality evidence. Dual combination therapy offers superior efficacy without increasing adverse events, and innovative strategies like the quadpill show promise for improved blood pressure management. For older adults, targeting an SBP of less than 150 mm Hg is beneficial, and thiazides are particularly effective in this age group. During pregnancy, antihypertensive drugs reduce the risk of severe hypertension but do not significantly impact other maternal or neonatal outcomes.
