Effects of beta-blockers on plasma lipids during antihypertensive therapy.
Several drugs used for antihypertensive therapy may interact with lipoprotein metabolism and may increase associated coronary risk levels. beta-Blocker monotherapy with selective or nonselective beta-blockers without intrinsic sympathomimetic activity (ISA) usually increases serum triglyceride and decreases high-density lipoprotein (HDL), especially HDL2 cholesterol concentration. With the exception of the nonselective 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 did not distinctly differ between selective and nonselective beta-blockers. Two beta-blockers possessing ISA, acebutolol, and pindolol did not show the increase in serum triglycerides and in serum total cholesterol or LDL cholesterol. Acebutolol showed the 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.
