Comparative effects of monatepil, a novel calcium antagonist with alpha 1-adrenergic-blocking activity, and nitrendipine on lipoprotein and carbohydrate metabolism in patients with hypertension.

Abstract

The effects of monatepil, a new calcium antagonist with alpha 1-blocking activity, and nitrendipine on lipoprotein and carbohydrate metabolism in 86 patients with mild-to-moderate hypertension were examined in a randomized, open-label, multicenter (32 hospitals) study. Thirty-nine patients treated with monatepil and 33 patients treated with nitrendipine completed the 12-week study. Monatepil and nitrendipine each significantly decreased both systolic and diastolic blood pressure. Changes in heart rate were not seen in either group. Monatepil administration significantly decreased total cholesterol, low density lipoprotein (LDL) cholesterol, the LDL cholesterol to high density lipoprotein (HDL) cholesterol ratio, apolipoprotein (Apo) B levels, and HbA1c levels, whereas no changes in these measurements were observed in nitrendipine-treated patients. Monatepil also significantly decreased lipoprotein(a) levels, but there were no significant changes in HDL cholesterol, Apo-AI, or Apo-E levels. After nitrendipine treatment, the C peptide concentration decreased significantly, although no significant changes were observed in fasting blood glucose or immunoreactive insulin levels. On the basis of these results, it can be concluded that monatepil belongs to a new class of antihypertensive calcium antagonist with favorable carbohydrate metabolism and lipid-lowering activity, although the clinical importance of these findings has not been established.
