Oral bunazosin hydrochloride, a new alpha 1-blocker, for 12 weeks was given to ten outpatients diagnosed as having essential hypertension associated with hypercholesterolemia. High-density lipoprotein (HDL) triglyceride, HDL3 cholesterol, and apolipoprotein E levels were significantly decreased by bunazosin treatment. The decrease in HDL triglycerides was a result of the decrease in HDL3 triglyceride levels. There were no significant changes in the other components. The ratio of cholesterol to triglycerides in the low-density lipoprotein (LDL) and HDL fractions was increased significantly after bunazosin treatment. Furthermore, the ratio of HDL2 cholesterol to HDL3 cholesterol after bunazosin treatment was significantly higher than before treatment. The results suggest that the catabolism of triglycerides in lipoprotein and the reduction in tissue cholesterol increase, and that bunazosin hydrochloride does not adversely affect the lipid component in hypertensive patients with hypercholesterolemia.

D006973	Hypertension	Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.

D008055	Lipids	A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D008074	Lipoproteins	Lipid-protein complexes involved in the transportation and metabolism of lipids in the body. They are spherical particles consisting of a hydrophobic core of TRIGLYCERIDES and CHOLESTEROL ESTERS surrounded by a layer of hydrophilic free CHOLESTEROL; PHOSPHOLIPIDS; and APOLIPOPROTEINS. Lipoproteins are classified by their varying buoyant density and sizes.	Circulating Lipoproteins,Lipoprotein,Lipoproteins, Circulating
