Hypolipidemic drugs are needed in addition to anti-diabetic therapies. They are used for hypercholesterolemic conditions if triglyceride concentration is acceptable. It exists a book entitled the Effect of Hypolipidemic Drugs on Diabetic Retinopathy [diabetic retinopathy]. Unfortunately, I cannot remember the name of its author. It's a very interesting book which talks about hypolipidemic drugs and other treatments of this illness. So, I'm sure that it also talks about heparinoids, anabolic steroids and vitamins.
