  • Title: Plasma lipid lowering effects of doxazosin, a new selective alpha1 adrenergic inhibitor for systemic hypertension.
    Author: Pool JL.
    Journal: Am J Cardiol; 1987 May 29; 59(14):46G-50G. PubMed ID: 2884853.
    Abstract:
    Hypertension and hypercholesterolemia are 2 major risk factors for atherosclerotic coronary artery disease (CAD). Elevations of both blood pressure and serum cholesterol levels should be reduced to control CAD risk. Doxazosin is a once-daily, long-acting, selective alpha 1-adrenergic inhibitor that is effective for the treatment of essential hypertension. During controlled studies of doxazosin's antihypertensive efficacy, 3 serum lipid parameters were measured; total cholesterol, total triglyceride and high density lipoprotein (HDL) cholesterol. In 10- to 12-week placebo-controlled studies, 142 doxazosin-treated patients were compared with 155 placebo-controlled subjects. Doxazosin patients had an increase of 8.9% in the HDL/total cholesterol ratio (p less than 0.05), whereas total cholesterol, HDL cholesterol and triglyceride levels were not significantly different between the 2 study groups. During a 52-week comparison of doxazosin versus atenolol, doxazosin treatment was associated with a significant decrease in total triglyceride levels (5%; p less than 0.001) and increases in HDL cholesterol levels (3.9%; p less than 0.01) and HDL/total cholesterol ratio (5.4%; p less than 0.0001). Doxazosin is an effective antihypertensive agent that has a favorable impact on serum lipid levels, thereby promoting a beneficial effect on 2 major CAD risk factors.
