[Lisinopril and nifedipine have neutral effects on lipids]

In a randomized, double blind, parallel-group, multicentre study in Norway, 97 patients with mild to moderate hypertension (mean blood pressure 159/104 mm Hg) were treated with either lisinopril 10-40 mg or nifedipine 20-80 mg and the effects on blood lipids were evaluated. Complete results of laboratory analyses are given for 80 patients. After a 4 week run-in and placebo period, antihypertensive treatment was given for the next 10 weeks. During treatment with lisinopril the changes in lipids were +2.1% for total cholesterol, +0.7% for HDL-cholesterol, +3.8% for triglycerides and -6.1% for ratio HDL/cholesterol-HDL. For nifedipine the corresponding values were -2.4% for cholesterol, -5.8% for HDL-cholesterol, +8.0% for triglycerides and +3.2% for ratio. None of these changes was statistically significant. Both lisinopril and nifedipine lowered the blood pressure significantly, 18.1/12.0 mm Hg with lisonopril (p < 0.01 for both systolic and diastolic pressure) and 8.0/8.5 mm Hg with nifedipine (p < 0.01 for both respectively). Both drugs were well tolerated. In conclusion, neither lisinopril nor nifedipine had any negative impact on lipid levels.
