  • Title: Effect of beta blockers on blood lipid profile.
    Author: Lehtonen A.
    Journal: Am Heart J; 1985 May; 109(5 Pt 2):1192-6. PubMed ID: 2859784.
    Abstract:
    Several drugs used for antihypertensive therapy may interact with lipoprotein metabolism and increase associated coronary risk factors. Beta-blocker monotherapy with cardioselective or noncardioselective beta blockers without intrinsic sympathomimetic activity (ISA) usually increases serum triglyceride and decreases the concentration of high-density lipoprotein (HDL), especially HDL2 cholesterol. With the exception of the noncardioselective beta blocker sotalol, beta-blocker therapy has little influence on the serum total cholesterol or low-density lipoprotein (LDL) cholesterol concentrations. The magnitude of these changes in serum lipids does not significantly differ between cardioselective and noncardioselective beta blockers. Two beta blockers possessing ISA, acebutolol and pindolol, did not increase serum triglycerides and serum total cholesterol or LDL cholesterol. Acebutolol produced a nonsignificant decrease in HDL cholesterol level. Pindolol, with marked ISA, exhibited the most favorable lipid profile, increasing serum HDL cholesterol and the ratio of HDL cholesterol to total cholesterol. The concentration of apolipoprotein A-I increased slightly during pindolol therapy. Beta blockers, with the exception of pindolol, decrease the concentration of serum free fatty acids. Beta-blocker therapy has little influence on the adipose tissue lipoprotein lipase activity, but lecithin cholesterol acyltransferase activity may increase during pindolol therapy. Thus beta-blocking drugs possessing ISA, such as acebutolol and pindolol, might be desirable choices as antihypertensive agents, since they do not appear to produce adverse effects on the lipid profile.
