No rise in LDL-CH has been observed in patients with high TG levels. Its t 1/2 is 20 hr. Adverse effects are myalgia, hepatitis, rashes. Cholelithiasis and rhabdomyolysis are rare. Fenofibrate appears to be the most suitable fibrate for combining with statins, because statin metabolism is minimally affected and enhancement of statin myopathy risk is lower. Indications of fenofibrate are similar to that of gemfibrozil. Gemfibrozil is the drug of choice for patients with markedly raised TG levels, whether or not CH levels are also raised. Episodes of acute pancreatitis are prevented in patients with chylomicro naemia and severe hypertriglyceridaemia. It is mo*t effective in type III hyperlipoproteinaemia; also a first line drug in type IV and type V disease.
