Effects of manidipine and delapril on glucose and lipid metabolism in hypertensive patients with non-insulin-dependent diabetes mellitus.
Effects of manidipine, a new calcium antagonist, and delapril, an angiotensin converting enzyme inhibitor, on glucose and lipid metabolism were investigated in mild to moderate hypertensive patients with non-insulin-dependent diabetes mellitus (NIDDM). The patients were treated with either manidipine 10 mg/day (n = 12, mean age 63 +/- 2 years) or delapril 30 mg/day (n = 8, 62 +/- 3 years) for 12 weeks. Glucose and insulin (IRI) responses to 75 g oral glucose load, glycosylated hemoglobin A1c (Hb A1c), serum levels of total cholesterol (TC), high-density lipoprotein (HDL) cholesterol, triglyceride and apolipoproteins, and 24 h urinary excretion of C-peptide were measured before and at the end of treatment. Both manidipine and delapril showed adequate hypotensive effects. Neither manidipine nor delapril affected blood glucose and IRI responses to glucose load. Manidipine showed no effect on lipids whereas delapril increased HDL cholesterol (47 +/- 5 mg/dL to 61 +/- 7, p < 0.05), although total cholesterol and triglyceride were not altered. The ratio of TC-HDL cholesterol/HDL cholesterol was decreased by delapril (3.44 +/- 0.30 to 2.61 +/- 0.45, p < 0.05). There were no significant changes in apolipoproteins. Both manidipine and delapril have adequate antihypertensive actions without unfavorable effects on glucose and lipid metabolism in hypertensive patients with NIDDM. Delapril seems to have a beneficial effect on lipid metabolism.
