Antihypertensive Efficacy: Captopril vs Lisinopril
Several studies have directly compared the antihypertensive effects of captopril and lisinopril. Across multiple trials, lisinopril generally produced a greater reduction in both systolic and diastolic blood pressure compared to captopril, although not all differences reached statistical significance. Lisinopril was especially more effective in maintaining lower blood pressure during the last hours of the 24-hour dosing interval, indicating a longer duration of action and better 24-hour control when used once daily, compared to captopril, which is typically dosed twice daily 1235+2 MORE.
In studies using ambulatory blood pressure monitoring, lisinopril consistently showed a greater and more sustained reduction in blood pressure throughout the day and night. The percentage of patients achieving target blood pressure was also higher with lisinopril monotherapy compared to captopril . When combined with hydrochlorothiazide, lisinopril also led to a greater fall in diastolic blood pressure than captopril, though both combinations were well tolerated .
Efficacy in Heart Failure: Lisinopril vs Captopril
For patients with symptomatic congestive heart failure, lisinopril improved exercise capacity more than captopril over a 12-week period. Both drugs were generally well tolerated, but lisinopril led to a greater improvement in New York Heart Association (NYHA) class and had fewer adverse reactions in high-risk patients with severe heart failure 46.
Endothelial Progenitor Cell (EPC) Migration: Lisinopril vs Captopril
In laboratory studies examining the effect on endothelial progenitor cell migration, both captopril and lisinopril increased EPC migration in a dose-dependent manner. At high doses, lisinopril had a significantly greater effect on EPC migration than captopril, suggesting a potential advantage for vascular repair and cardiovascular health, especially in patients with coronary artery disease .
Safety and Tolerability
Both captopril and lisinopril were generally well tolerated in the studies reviewed. The incidence of side effects was low and similar between the two drugs, with only rare cases requiring discontinuation. Lisinopril may have a slight advantage in terms of fewer adverse reactions in some patient groups 2346+2 MORE.
Conclusion
Lisinopril is at least as effective as captopril for lowering blood pressure and treating heart failure, with evidence suggesting it may be more potent, longer acting, and provide better 24-hour blood pressure control. Lisinopril also appears to have a greater effect on endothelial progenitor cell migration at higher doses, which may offer additional cardiovascular benefits. Both drugs are generally safe and well tolerated, but lisinopril’s once-daily dosing and sustained efficacy make it a preferred choice in many clinical scenarios.
