Top-Selling Prescription Drug Mismarketed to Women?

From the PharmaLive.com News Archive - Sep. 17, 2008
ITHACA, N.Y. – September 17, 2008 – Lipitor has been the top-selling drug in the world and has accounted for over $12 billion in annual sales. It has been prescribed to both men and women to lower cholesterol and reduce the risk of heart attack and stroke in patients with common risk factors for heart disease. However, a new study appearing in the Journal of Empirical Legal Studies was unable to find high quality clinical evidence documenting reduced heart attack risk for women in a primary prevention context. Furthermore, advertising omits label information relevant to women.

Theodore Eisenberg of Cornell Law School and Martin T. Wells of Cornell University assembled studies for a meta analysis of drugs’ effects on cardiovascular risk, taking into account all relevant studies reporting risks for both men and women.

Not one of the studies that included women with a mixture of risk factors for heart attacks provided statistically significant support for prescribing Lipitor or other statins to protect against cardiovascular problems. Pfizer’s claims of clinical proof that Lipitor reduces risk of heart attack in patients with multiple risk factors for heart disease does not appear to be scientifically supported for large segments of the female population.

In addition, Lipitor’s advertising repeatedly fails to report that clinical trials were statistically significant for men but not for women. Unqualified advertising claims of protection against heart attacks may therefore be misleading. Pfizer’s advertising also does not disclose critical portions of the Lipitor FDA-approved label, which acknowledges the absence of evidence with respect to women.

“Our findings indicate that each year, reasonably healthy women spend billions of dollars on drugs in the hope of preventing heart attacks but that scientific evidence supporting their hope does not exist,” the authors conclude.

This study is published in the September 2008 issue of the Journal of Empirical Legal Studies.

This article shows the increased scrutiny of the pharmaceutical industries medical studies, medical claims and marketing practices.

As many of you already know, I am not a big fan of Lipitor or other statins, such as Crestor, Pravachol, Zocor, Mevacor and Lescol. Their use in prevention of heart disease leaves a lot to be desired. While not being a fan of statin drugs, I still am a fan of the pharmaceutical industry, just as I am a fan of the vitamin and neutraceutical industries, as long as their claims are valid and marketed truthfully.

I hope I am wrong, but this article from the Journal of Empirical Legal Studies may be a trial balloon for legal trouble for the pharmaceutical industry. We may soon see health insurers, Medicare and State Medicaid filing lawsuits worth billions of dollars to recover money spent on alleged false claims for Lipitor.
There are other methods of reducing heart disease risk, that do not rely on drugs. Eating and exercising properly. quitting tobacco, and reducing alcohol intake are just a few. The goal is not to lower your cholesterol number to the lowest it can go, but to increase your age to the highest it can go, but in a safe, effective and healthy manner that increases your quality of life. That is the goal of my practice, and I hope it is yours as well.

Ghostwriters for medical research criticized, reforms urged

By LINDSEY TANNER, AP Medical Writer 27 minutes ago

Two new reports involving the painkiller Vioxx raise fresh concerns about how drug companies influence the interpretation and publication of medical research.

The reports claim Merck & Co. frequently paid academic scientists to take credit for research articles prepared by company-hired medical writers, a practice called ghostwriting. They also contend Merck tried to minimize deaths in two studies that showed that the now withdrawn Vioxx didn't work at treating or preventing Alzheimer's disease.

Merck called the reports in Wednesday's Journal of the American Medical Association false and misleading. Five writers of the articles were paid consultants for people who sued Merck over Vioxx's heart and stroke risks; the sixth testified about Merck and Vioxx's heart risks before a Senate panel. Merck says those connections makes the reports themselves biased.

While Merck is singled out, the practices are not uncommon, according to JAMA's editors. In an editorial, they urge strict reforms, including a ghostwriting crackdown and requiring all authors to spell out their specific roles.

Dr. Catherine DeAngelis, JAMA's editor-in-chief, said those are already policies at JAMA but not at many other journals.

"The manipulation is disgusting. I just didn't realize the extent," she said.

The practices outlined in JAMA can lead editors to publish biased research that can result in doctors giving patients improper and even harmful treatment, she said.

DeAngelis said doctors, medical researchers and journal editors bear some responsibility for those harms.

"We're the ones who have allowed this to happen. Now we've got to make it stop," she said.

Drug studies involve several steps, including designing and performing the research, analyzing the results and writing them up for submission to a medical journal. Pharmaceutical companies sometimes pay for a study but have independent scientists perform all those steps. Sometimes companies and their own scientists are involved in some or all the steps, and those were the studies scrutinized in the JAMA reports.

The articles are based on reviews of company documents from court cases over Vioxx, which was pulled in 2004 because of its heart and stroke risks. Merck agreed to pay $4.85 billion last November to settle thousands of lawsuits.

One JAMA report says internal company data showed in 2001 that Vioxx patients in two Alzheimer's studies had a higher death rate than patients on dummy pills. Merck didn't publicize that "in a timely fashion" and provided information to federal regulators that downplayed the deaths, the report said.

But Jim Fitzpatrick, a Merck attorney, said "it's completely not true" that Merck tried to minimize those deaths. He said a Merck analysis found the excess deaths were not related to Vioxx.

The other JAMA article says one Alzheimer study was designed and conducted mainly by Merck scientists. But when published, the lead authors listed were academic scientists not named in a study draft.

Peter Kim, head of Merck Research Laboratories, said those authors "were intimately involved in the studies." One was New York University Alzheimer's specialist Steven Ferris. He also disputed the implication that he had little to do with the study, and said Merck paid him for his work.

Fitzpatrick acknowledged that Merck has hired outside firms to write drafts of other studies that later list scientists as first authors. In those cases, the scientists are expected to review the manuscript and can suggest changes, he said.

The Alzheimer study was published in 2005 in the journal Neuropsychopharmacology. Its new editor, Dr. James Meador-Woodruff, said the journal's policies have been strengthened to ban ghostwriting.

If we did not trust the pharmaceutical industry before, how can we now?
Can we believe the hype and advertising that comes from this industry?
For those of you who know me well, I am not a big fan of medication. I prefer to use the least amount possible, and only after exhausting other options. I always prefer to find the cause of the problems and treat the cause with lifestyle adjustments first.
It sometimes take a little longer to come up with the solution, but it may save you both medication side effects and the cost of expensive medications.
If you think you are taking too much medication, please schedule an appointment so we can truly the assess their need, their benefits and their possible risks.
Always remember, that I work for you! Not for your insurance, not for the government!
You will get individualized and personal care and advice. That is what Family Practice is all about!!
