Lisinopril vs Statins: Mechanisms and Primary Effects
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor mainly used to lower blood pressure, while statins are primarily used to reduce cholesterol and prevent atherosclerosis. Both drug classes have additional effects beyond their main uses, including impacts on vascular health, inflammation, and oxidative stress 49.
Blood Pressure and Cholesterol Control
Lisinopril effectively reduces blood pressure, but does not significantly lower cholesterol levels. Statins, on the other hand, are effective at lowering cholesterol but have only a modest effect on blood pressure. When used together, lisinopril and statins can provide both blood pressure and cholesterol control, which is beneficial for patients with both hypertension and high cholesterol 469.
Antioxidant and Endothelial Effects
Both lisinopril and statins have been shown to improve antioxidant enzyme activity in red blood cells, which may help protect tissues from oxidative damage. Studies found that both lisinopril alone and lisinopril combined with simvastatin increased catalase activity and decreased glutathione peroxidase activity in patients with hypertension, suggesting similar antioxidant benefits from both treatments 14. Additionally, both drugs can improve endothelial function, which is important for vascular health. Improvements in flow-mediated dilation (FMD), a measure of endothelial function, were observed with both lisinopril and statins in patients with vascular disease 28.
Combined Therapy: Additive and Synergistic Benefits
Combining lisinopril with a statin can offer additional benefits compared to either drug alone. In patients with advanced kidney disease, the combination of lisinopril and simvastatin was more effective at reducing proteinuria, improving kidney function, and limiting kidney damage than either drug alone . In hypertensive patients, adding a statin to lisinopril therapy further improved the elastic properties of arteries and reduced vascular stiffness, as shown by decreases in augmentation index and pulse wave velocity . These combined effects may be especially important for patients at high cardiovascular risk.
Inflammation and Special Populations
Lisinopril has shown anti-inflammatory effects, such as reducing high-sensitivity C-reactive protein (hsCRP) and tumor necrosis factor-alpha (TNF-α) in people with HIV on antiretroviral therapy, while statins did not show significant changes in inflammatory markers in this group . This suggests that lisinopril may have unique anti-inflammatory benefits in certain populations.
Safety and Tolerability
Both lisinopril and statins are generally well tolerated, but adherence to lisinopril may be lower in some patients due to missed doses, as observed in a study with HIV-positive individuals . Side effects were infrequent in both drug groups.
Conclusion
Lisinopril and statins have distinct primary effects—blood pressure reduction and cholesterol lowering, respectively—but both also improve vascular health and antioxidant status. When used together, they can provide additive benefits, including better control of blood pressure, cholesterol, vascular stiffness, and kidney protection, especially in high-risk patients. Both drugs also improve endothelial function, and lisinopril may offer additional anti-inflammatory effects. The combination of these medications is particularly valuable for patients with multiple cardiovascular risk factors or advanced organ damage.
