The data do not suggest that any one ACE inhibitor is better or worse at lowering BP .
ACE inhibitor doses above Max did not significantly lower BP more than Max .
There are no clinical ly meaningful BP lowering differences between different ACE inhibitors .
BACKGROUND ACE inhibitors are widely prescribed for hypertension so it is essential to determine and compare their effects on blood pressure ( BP ) , heart rate and withdrawals due to adverse effects ( WDAE ) .
OBJECTIVES To quantify the dose-related systolic and /or diastolic BP lowering efficacy of ACE inhibitors versus placebo in the treatment of primary hypertension .
Twenty-four hour blood pressure effect of once-daily lisinopril, enalapril, and placebo in patients with mild to moderate hypertension.
This multicentre , double-blind , parallel-group , placebo-controlled study compared the antihypertensive effects of equal doses of two long-acting angiotensin converting enzyme ( ACE ) inhibitors . After a two-week , placebo run-in phase , 110 patients with mild to moderate hypertension were r and omised to receive 10 mg lisinopril or enalapril , or placebo for 4 weeks . Office BPs were measured at regular intervals throughout the study . Twenty-four hour ambulatory blood pressure ( ABP ) was measured at baseline and after the first and final doses of study drug . Serum ACE activity and aldosterone were obtained concomitantly with each ABP monitoring . Office BP differences from placebo reached ( P less than 0.05 ) or approached ( P less than 0.10 ) statistical significance at all observations for the lisinopril group but were not significant for any observation in the enalapril group and approached significance on two occasions . After four weeks of treatment , ABP analysis revealed that the lisinopril and enalapril groups , when compared with placebo , had similar and significant systolic and diastolic AUC reductions ( P less than 0.01 ) from baseline over the 24 h dosing interval . During the second half of the dosing interval , 13 - 24 h post drug administration , the lisinopril group was significantly different from placebo ( systolic BP , P = 0.002 ; diastolic BP , P = 0.005 ) while the enalapril group was not . Both drugs were well tolerated . The results indicate that monotherapy with 10 mg of lisinopril is as effective as with 10 mg of enalapril , and that ABP monitoring is useful in more precisely depicting the clinical effect of the known pharmacokinetic properties of these two agents
