The effects on blood lipids and uric acid of six different antihypertensive drugs used alone, and of five different combinations of two antihypertensive drugs, are reported here. Prazosin significantly lowered serum low density lipoprotein and very low density lipoprotein (LDL + VLDL) cholesterol and total triglycerides while maintaining high density lipoprotein (HDL) levels. Atenolol lowered LDL + VLDL cholesterol slightly. Both pindolol and hydrochlorothiazide (HCTZ) were neutral, while oxprenolol increased total triglycerides. Propranolol lowered HDL cholesterol and increased total triglycerides and uric acid. The combination of prazosin plus pindolol has a direct favorable lipid profile, while the combination of propranolol plus HCTZ lowered HDL cholesterol and increased total triglycerides. The combination of propranolol plus prazosin lowered HDL cholesterol, but to a lesser degree than propranolol alone, which suggests that prazosin was not able to completely counteract the negative effects of propranolol on HDL. Methyldopa plus HCTZ, and HCTZ plus amiloride were neutral with regard to effects on blood lipids. It is suggested that the metabolic effects of antihypertensive drugs could be of special importance in the long-term treatment of mild hypertension.
