"Cholesterol Drug Bombs"-New York Times Editorial Misses Opportunity

Yesterday, the New York Times editorial board wrote "there have long been suspicions, but it was still very disturbing to learn this week that a heavily promoted cholesterol-lowering drug had flunked a clinical trial of its effectiveness in reducing fatty deposits in arteries....The drug, Zetia, and a combination pill that contains it, Vytorin...generated more than $5 billion in sales last year."

You probably know the ads for Vytorin. They have run on T.V., in magazines and on-line. They certainly are clever, creative and very expensive. According to Nielsen Monitor-Plus, in 2006 the companies spent $136.3 million to advertise Vytorin and $115 million from January to October of 2007.

Vytorin combines Zocor, a statin produced by Merck (and also marketed by generic drug manufactures and sold at lower prices) with the Schering-Plough's Zetia. Statins work by reducing the production of cholesterol in the liver. Zetia works to reduce the absorption of dietary and liver-produced cholesterol from the intestines into the blood stream.

The study compared the effects of treating patients with Vytorin, the combination drug, with a statin alone. The patients all had abnormally high LDL cholesterol. In the study, LDL cholesterol was reduced more significantly by Vytorin than with the statin alone. These results are consistent with the results of a number of other studies.


It also was hypothesized that the added cholesterol-lowering effect of Vytorin would lead to a more significant reduction of arterial plaque growth. This relationship did not hold. The lower cholesterol achieved by the Vytorin did not yield a reduction in plaque build-up as compared to the statin only. In fact, the Vytorin group was found to have a more rapid development of plaque than the statin-only group.

The Times reports that these companies had been “cynically sitting on the results for more than a year” while spending hundreds of millions of dollars to convince consumers that the Vytorin is a preferred cholesterol drug. This certainly is a very legitimate criticism.

The Times continued that "the findings also raise doubts about the current belief that lowering cholesterol is the key to cardiovascular health. The study showed that Vytorin reduced bad cholesterol significantly more than Zocor alone. The problem was that it failed to reduce the formation of plaque."


And here is perhaps were the Times should have been somewhat more careful. This study now represents a single set of data among a sea of data that concludes lower LDL cholesterol lowers the risks of heart attacks and strokes. Numerous studies also indicate that LDL cholesterol above 100mg/dl will lead to the development of arterial plaque.

Instead of casting doubt on the general wisdom of cholesterol management, the Times would have served the public well by offseting the barrage of pharmaceutical advertising and reinforce the well-documented science regarding natural alternatives to cholesterol management. An extensive NIH report (http://www.nhlbi.nih.gov/health/public/heart/chol/chol_tlc.htm), for instance, concludes that the "amount of LDL reduction from Therapeutic Lifestyle Changes compares well with many of the cholesterol-lowering drugs." Among the recommendations are the consumption of certain positive nutrients such as plant sterols, soluble fibers, monounsaturated fats in place of saturated and trans fats, and Omega-3s. Needless to say, weight management and exercise is part of the NIH recommendations.
