Statins do not affect the activity of lipoprotein and hepatic lipase, have no significant effect on the synthesis and catabolism of free fatty acids, thats why their effect on TG levels again and indirectly through their main effects on reducing LDL-C.

According to the controlled studies of Simvastatin increases HDL-C to 14%.
