Purported mechanism
Fenofibrate is a prodrug hydrolyzed to fenofibric acid, a peroxisome proliferator-activated receptor α (PPARα) agonist; PPARα activation upregulates lipoprotein lipase and apolipoprotein A-I/A-II expression and downregulates apolipoprotein C-III, accelerating VLDL clearance and lowering plasma triglycerides 30-50%.0 Modest HDL rise; LDL effects mixed. Renally cleared; combination with statin carries elevated myopathy risk (greater for gemfibrozil than fenofibrate, but caution still warranted)[1].
