The aim of this study was to compare the effects of long-term monotherapy with four different beta-blockers on plasma lipids in hypercholesterolemic hypertensive patients. We studied 152 subjects with essential hypertension [diastolic blood pressure (DBP) >90 mm Hg], total cholesterol (TC) >240 and <330 mg/dl, and triglycerides (TGs) <300 mg/dl. After a 4-week washout period with placebo, patients were randomized to receive propranolol, 160 mg/day (n = 37), atenolol, 100 mg/day (n = 38), bisoprolol, 10 mg/day (n = 39), or celiprolol, 400 mg/day (n = 38), for 18 months. No cholesterol-reducing drug was allowed. Blood samples for evaluation of TC, low-density lipoprotein cholesterol (LDL-C), HDL cholesterol (HDL-C), and TGs were taken before and after the placebo period and subsequently every 6 months. No beta-blocker worsened TC or LDL-C. Nonselective propranolol caused the most pronounced changes in HDL-C and TGs. Beta1-Selective atenolol produced the same qualitative effects, but to a lesser extent. The more beta1-selective bisoprolol did not affect HDL-C and TGs. Celiprolol significantly improved the lipid profile by significantly decreasing TC, LDL-C, and TGs, and increasing HDL-C. These findings suggest that in hypercholesterolemic hypertensive patients, (a) beta1-selective beta-blockers are likely to adversely affect plasma lipids to a lesser extent than nonselective ones; and (b) celiprolol is able to improve the lipid pattern, which could be because of its peculiar ancillary properties.
