    Abstract:
    The effects on plasma lipids and apoproteins A-I and B of oral administration of doxazosin and atenolol over a 20-week period were studied in 42 patients with mild to moderate essential hypertension. Total plasma cholesterol decreased by 8.9% (P less than 0.01) and LDL cholesterol by 16.9% (P less than 0.01) after 20 weeks' treatment with doxazosin. Total HDL cholesterol and HDL2 cholesterol concentrations increased slightly during doxazosin treatment and the increase in HDL2 level at 4 weeks was statistically significant (P less than 0.05). At 20 weeks, the levels of total HDL cholesterol and HDL2 were significantly (P less than 0.05) lower with atenolol than with doxazosin. The ratio HDL/total cholesterol increased during doxazosin treatment (P less than 0.05 at 4, 12 and 20 weeks). The HDL/total cholesterol ratio was significantly higher after 20 weeks with doxazosin than with atenolol (P less than 0.05). The levels of VLDL cholesterol and triglycerides increased significantly (P less than 0.01) during atenolol treatment. The concentrations of apoproteins A-I and B did not change significantly during treatment with doxazosin or with atenolol but at 20 weeks the ratio of apo A-I to apo B was significantly (P less than 0.05) lower with atenolol than with doxazosin. On the basis of these results, doxazosin would seem to have significant favourable effects on the serum lipid profile.
