Effects of acebutolol on the serum lipid profile.
Epidemiological and recent interventional studies have emphasised the relationship between plasma lipid parameters and the incidence of coronary heart disease. beta-Blockers, particularly those without intrinsic sympathomimetic activity (ISA), are generally reported to increase triglyceride levels and decrease high density lipoprotein (HDL)-cholesterol levels, both changes theoretically increasing the risk of coronary heart disease. A review of all published trials concerning the effects of acebutolol (a cardioselective beta-blocker with mild ISA) on the plasma lipid profile was carried out, with a particular emphasis on studies reporting a comparison with other beta-blockers. The results indicate that, on average, acebutolol does not have any adverse effects on plasma lipids and may even reduce total and low density lipoprotein (LDL)-cholesterol by 7 and 5%, respectively. In contrast, the other beta-blockers compared under the same conditions (propranolol, pindolol and penbutolol) tended to increase triglyceride levels (+19% when compared with acebutolol) and decrease HDL-cholesterol (-7% when compared with acebutolol) to an extent that was consistent with previous reports in the literature. In interpreting these differences in lipid parameters in the light of epidemiological and interventional study data, the use of acebutolol as opposed to the other beta-blockers could theoretically lead to a relative reduction in coronary risk of 20% or more.
