Which lipid-lowering agent is generally most potent at lowering triglycerides?

Fibrates are the most potent triglyceride-lowering agents because they activate PPAR-α, which increases lipoprotein lipase activity and enhances clearance of triglyceride-rich particles. They also reduce hepatic VLDL production and promote fatty acid oxidation in the liver, leading to substantial drops in triglycerides. Niacin lowers triglycerides as well, but its TG-reducing effect is less robust and can be limited by side effects like flushing and glucose intolerance. Statins primarily target LDL cholesterol and have only modest effects on triglycerides. Bile acid sequestrants mainly lower LDL and can even raise triglycerides in some patients. So, among these options, fibrates give the strongest triglyceride reduction.
