The effect of metoprolol on plasma lipids

Fifteen hypertensive patients entered a single-blind study to examine the effects of metoprolol (100 mg twice daily) on fasting plasma lipids. In 12 patients who completed the study, non-esterified fatty acid concentrations fell, but cholesterol and triglyceride levels were unchanged after 12 weeks' treatment. These results conflict with earlier reports of the effect of metoprolol on plasma triglyceride concentrations.
