A MULTICENTER ANALYSIS OF THE USE OF ENALAPRIL AND LISINOPRIL IN ELDERLY HYPERTENSIVE PATIENTS

OBJECTIVE: To evaluate the clinical use and adverse effects of enalapril and lisinopril in elderly hypertensive subjects. DESIGN: A multi-center, retrospective, drug use evaluation survey. SETTING: Ambulatory care clinics at 14 VA and 14 academic medical centers. PATIENTS: 422 elderly (>60 years of age) patients with hypertension and no clinical evidence of congestive heart failure. INTERVENTION: At least 3 consecutive months of antihypertensive therapy with either enalapril or lisinopril. MEASUREMENTS: Blood pressure, serum creatinine, serum potassium, concomitant disease states, concurrent medications, and documentation of any adverse event that might be related to ACE inhibitor therapy. RESULTS: There were no significant differences in systolic and diastolic blood pressures, serum creatinine, or serum potassium between enalapril- and lisinopril-treated patients at baseline and after 3 months of therapy. Both treatments resulted in a significant reduction in diastolic blood pressure. There was no significant difference in the incidence of adverse effects between the two treatments. Significantly more patients were dosed on a twice daily regimen of enalapril than lisinopril. CONCLUSION: The data from this retrospective study confirm the safe and effective use of enalapril and lisinopril, two long-acting ACE inhibitors, in elderly hypertensive patients.
