Type 2 diabetes patients may be wasting billions of dollars on unnecessary medication. Three doctors who recently evaluated the effectiveness of commonly prescribed fibrates in diabetes patients with high cholesterol have said that the drugs have not been proven effective. The doctors, who conducted the research for the FDA, reported their findings in a commentary in the New England Journal of Medicine.

Diabetics are at high risk of cardiovascular disease, and fibrates are commonly prescribed along with statins and diabetes medication to lower the risk of heart attacks. The statins and fibrates were thought to work in combination to lower “bad” LDL cholesterol and raise “good” HDL cholesterol levels.

But, although fibrates such as Tricor (fenofibrate), Lopid (gemfibrozil) and Trilipix (fenofibric acid) are routinely prescribed to diabetics, there have been few studies assessing their effectiveness. “Thousands and thousands of Americans take fibrates every day,” said one of the commentary’s authors, Dr Sanjay Kaul from the Cedars-Sanai Heart Institute, “But so far there are no long-term studies showing that fibrates lower cardiovascular risk or improve survival among diabetes patients who are also on statins.”

The commentary authors are calling for more studies, and recommending doctors only prescribe fibrates along with statins to diabetics at high risk of heart attack, and only after they have achieved healthy LDL levels.

While no diabetic should adjust their diabetes medication without consulting their physician, many type 2 diabetics may be able to lower the cost of their diabetes medicine without affecting their diabetes control based on this new recommendation.

Model of the human heart

The type 2 diabetes drug metformin is safer for the heart than other older diabetes medication, according to a two-year study. The findings are important because older patients with diabetes are at particular risk for cardiovascular disease, and because many of them are prescribed a class of diabetes medications called sulfonylureas that may raise this risk.

The controversial diabetes drug Avandia, which has been linked to heart problems, is a sulfonylureas diabetes drug. Sulfonylureas have also been linked to episodes of low blood sugar, and to weight gain.

Sulfonylureas drugs and metformin (also known by the brand name Glucophage) lower blood sugar in different ways. Metformin works by suppressing sugar production in the liver, while sulfonylureas work by increasing insulin production. To read more about the study findings on WebMD, >CLICK HERE.<

Artery cross section

As if having diabetes isn’t troubling enough, the British Heart Foundation is now warning that type 2 diabetics are more likely to have a newly discovered super-sticky “ultra bad” form of cholesterol. This extra sticky cholesterol is more likely to adhere to and build up in the arteries, forming dangerous artery-narrowing plaque. These narrowed or blocked arteries are the cause of coronary heart disease and resulting heart attacks and strokes.

The super-sticky cholesterol, called MGmin-LDL, is formed by the bonding of a sugar molecule (such as glucose or fructose) to a lipid molecule (such as low density lipoprotein) in a process called glycation. Glycation changes the shape of LDL molecules, making them smaller and denser and creating more exposed areas that are likely to stick to artery walls.
