Health Freedom Under Attack!

Wyeth Pharmaceuticals, maker of drugs like Premarin® and Prempro®, has asked the FDA to deny Americans access to bioidentical hormone replacement therapies sold by compounding pharmacies. Learn why Wyeth's petition is nothing more than an attempt to manipulate the FDA into suppressing Americans' access to safer and less expensive hormone drugs, and what you can do to turn back this egregious assault on health freedom.

Throughout its 26-year history, the Life Extension Foundation has worked tirelessly to educate the public about novel, scientifically supported ways to prevent the diseases of aging and to halt and even reverse the aging process itself. As part of this mission, Life Extension has relentlessly challenged the FDA, drug companies, and others who would limit or abolish access to these lifesaving therapies.

Today, one of the world's largest drugmakers is asking the FDA to deny Americans access to bioidentical hormone replacement drugs. As Life Extension readers know, levels of life-sustaining hormones plummet in aging adults. The debilitating health effects of depleted hormones are perhaps most acutely felt by women undergoing menopause. Restoring these essential hormones to youthful levels confers health benefits to aging women and men alike, including relief from depression, insomnia, and other miseries associated with hormone deficiencies, such as migraine headaches, low energy, low libido, and mental fatigue.1-3

Last fall, multibillion-dollar drug giant Wyeth Pharmaceuticals—the manufacturer of the hormone replacement drugs Premarin® and Prempro®—filed a “citizen's petition” with the FDA, asking the agency to deny consumers access to compounded bioidentical hormones. Prepared by compounding pharmacies and available only under a doctor's prescription, these custom-made preparations combine individualized doses of hormones that are chemically identical to those found in the human body. Bioidentical hormone replacement therapy has soared in popularity in the last four years, after a landmark government study found that Wyeth's Premarin® and Prempro® drugs pose grave health risks to menopausal women.4,5

FDA approval of Wyeth's request would jeopardize access to compounded bio-identical hormone therapies not only for millions of menopausal women, but for all aging adults.6 Since Wyeth filed its petition, the FDA has been buried by an avalanche of more than 40,000 letters and emails, most of them urging the agency to reject the petition and protect Americans' access to compounded bioidentical hormone therapies.7

In this article, we examine this threat to Americans' health freedom, why Wyeth's petition should be rejected, and what you can do to preserve access to life-enhancing bioidentical hormone therapies.

Benefits of Bioidentical Hormone Replacement Therapy

As men and women grow older, their levels of life-sustaining hormones drop precipitously.8 This marked decline has been linked with conditions as varied as hot flashes, diminished libido, and decreased bone mass, among many others.3,9 As more and more studies documenting the dangerous side effects of prescription hormone drugs come to light, aging adults increasingly are seeking safe, effective therapies to achieve optimal hormone balance.

In recent years, growing numbers of doctors and patients have turned to bioidentical hormone replacement therapy. In contrast to conventional hormone replacement therapy with drugs such as Premarin® and Prempro®—which contain altered forms of hormones that differ chemically from those naturally found in humans—bioidentical hormone replacement utilizes hormones such as estriol, estrone, estradiol, progesterone, testosterone, dehydroepiandros-terone (DHEA), and pregnenolone that are molecularly identical to those found in humans.

Physicians who utilize bioidentical hormone replacement know that each patient has unique needs and thus requires an individualized prescription and treatment regimen. These doctors usually measure their patients’ hormone levels with specific blood tests before recommending an individualized course of therapy. They then write a prescription for the appropriate hormone treatment, which is dispensed by a pharmacy that offers specialized compounding services. Since each patient’s needs are different, the pharmacist freshly prepares each prescription according to the requirements set by the patient’s physician.

Bioidentical hormone replacement preparations from a compounding pharmacy have certain advantages and disadvantages compared to conventional hormone drugs. Unlike prescription hormone products such as Premarin®, many compounded products are not covered by health insurance. However, bioidentical formulations can be made without additives and dyes commonly found in conventional, one-size-fits-all prescription drugs.

Moreover, the use of compounded hormones allows for specialized, flexible dosing strategies. This is consistent with the most recent FDA Menopause and Hormones Fact Sheet (issued in July 2005), which recommends that menopausal hormone therapy should be used at the lowest doses for the shortest duration needed to achieve treatment goals.10

Christopher Turf is a registered pharmacist who serves as director of compounding and medical outreach for Pharmaca Integrative Pharmacy, a national chain of pharmacies based in Boulder, CO. In an interview with Life Extension, Turf noted, “Several hundred thousand women use compounded hormones every day. Many have previously used manufactured hormone products, but found that they were inadequate, because they did not control symptoms effectively or had unacceptable side effects. Women seem to need very specific doses of hormones that cannot always be met by conventional hormone replacement therapy products. When the patient, doctor, and pharmacist work together to find the precise blend of compounded hormones that a patient needs, the results are tremendously successful.”

Wyeth's Response to Falling Sales?

Wyeth is the world's largest manufacturer of prescription meno-pause hormones. In 2002, the massive Women's Health Initiative (WHI) study demonstrated that hormone replacement therapy using the company's menopause drug Premarin® increased the risk of stroke, while treatment with its Prempro® product not only raised stroke risk, but also increased the risk of breast cancer, heart attacks, and blood clots.4,5 As a direct result of the WHI findings, Wyeth saw its revenues from these drugs decline dramatically. Sales of Prempro® and Premphase®, which combine estrogen and progestin, and Premarin®, an estrogen-only pill, fell by more than 57% in just three years, from $2.07 billion in 2001 to $880 million in 2004.11

“Wyeth is the largest manufacturer of animal-derived hormone,” according to Steven Russell, RPh, president and CEO of Medaus Pharmacy, Inc., of Birmingham, AL, one of the leading compounding pharmacies in the country. “What is occurring now is that Wyeth's sales have plummeted over the years, because there has been more of an outcry from the public since the Women's Health Initiative and many physicians have investigated the use of bioidentical hormone therapy.”

In October 2005, Wyeth petitioned the FDA, requesting that it completely ban the bioidentical alternatives that women have been using in ever-increasing numbers to achieve optimal hormone balance. With bioidentical replacement therapy clearly reducing its market share, Wyeth asked the FDA to outlaw all compounded bioidentical hormone formulations that compete with its own discredited drugs. If Wyeth is successful, then menopausal women will have no choice other than to take potentially life-threatening hormone drugs or to forgo hormone replacement therapy altogether, thus enduring the physically and emotionally debilitating effects of menopause-induced hormone depletion.

Russell notes several significant differences between Wyeth's hormone drugs and bioidentical hormones. “First off, Premarin® is a brand-name product derived from pregnant horse urine,” explains Russell. “Bioidentical hormones, on the other hand, are identical to what the human body produces. Premarin® is not identical and has numerous side effects. Bioidentical hormones are non-patented, they can be compounded by a licensed pharmacist, and they are derived from plant sources. The end product is 100% identical to what the ovaries produce, and is usually less expensive than hormone drugs.”

New Heights of Hypocrisy

Wyeth and its lawyers submitted a citizen's petition seeking FDA actions to counter what Wyeth calls “flagrant violations of the law by pharmacies compounding bioidentical hormone replacement therapy drugs that endanger public health.”12 Wyeth's attorneys went out of their way to produce a document that appears reasonable on the surface. Who, after all, would oppose restrictions on drugs that endanger the public health? However, a review of Wyeth's petition shows that the company's arguments do not hold up under scrutiny.

According to Wyeth, American women are being duped by compounding pharmacies, which do not put the same “black box” warnings required for Wyeth's drugs on the labels of their compounded bioidentical hormone formulations. Wyeth maintains that these pharmacies allegedly violate the law by not informing women that all estrogen-containing hormone therapies present the same health risks. Wyeth further maintains that compounding pharmacies even advertise the availability of bioidentical hormone alternatives, resulting in the illegal “manufacture” of these “drugs” in violation of FDA rules for pharmaceuticals. Wyeth also claims that these bioidentical products are misbranded and adulterated. In its petition, Wyeth states that “the public interest requires that this activity, which is putting women's health and safety at risk, be stopped.”12

The Wyeth petition then requests that the FDA initiate enforcement actions in the form of seizures, injunctions, and/or warning letters against the offending compounding pharmacies. It demands that a package insert be included with each product sold, informing consumers that bioidentical hormone replacement products are drugs that lack FDA approval, are not manufactured in accordance with FDA requirements, and have not been demonstrated to be safe or effective for any use, or to be safer or more effective than FDA-approved hormone therapy products (such as Premarin® and Prempro®).

In addition, the petition demands that this package insert be mailed retroactively to all physicians and consumers who have prescribed or used bioidentical hormone replacement therapies in the previous 12 months. Wyeth's petition also requests that the FDA issue an alert or paper outlining the new regulations, including the stipulation that health care professionals and pharmacies can lawfully compound hormone replacement formulas only when a patient's needs cannot be met by an FDA-approved hormone therapy product.12

Remarkably, the Wyeth petition was endorsed by 11 non-profit health organizations, including the National Black Women's Health Project, the National Association of Nurse Practitioners in Women's Health, the North American Menopause Society, and the Society for Women's Health Research.13 While these various groups purport to represent the public interest, a telling analysis by the International Academy of Compounding Pharmacists suggests they may be more concerned with their own financial interests.14 In fact, all these groups have financial or professional ties to Wyeth. The National Black Women's Health Project, for example, has received sponsorship money from Wyeth for various events.15 The president and CEO of the National Association of Nurse Practitioners in Women's Health serves on both the Wyeth advisory board and its speakers' bureau.16 Wyeth underwrites three separate North American Menopause Society award programs for physicians and nurses,17 and serves as a member of the corporate advisory council for the Society for Women's Health Research.18

According to Eldred Taylor, MD, assistant clinical professor of OB/GYN at Emory University and director of the Women's Wellness Group, “Wyeth has all these organizations backing them that are financially supported by them. It looks impressive, but most of the members are financially tied to these people—so the only motive they have is maintaining that financial source.”

By contrast, members of the public without any financial ties to Wyeth—including thousands of women with first-hand experience using bioidentical hormone replacement therapy during menopause—have deluged the FDA with more than 40,000 comments on the petition. The vast majority of these letters and email messages submitted through the agency's website vehemently oppose the proposed restrictions.7,19 The FDA recently told Wyeth that it will need more than six months to review and respond to both the petition and the public comments it has received.

More Problems with Wyeth's Petition

While many Americans have contributed thoughtful critiques of the Wyeth petition, one of the most detailed, legally supported rebuttals was authored by the International Academy of Compounding Pharmacists (IACP).14 Apart from its flawed reasoning, Wyeth's request appears to be unlawful on its face, since by law, citizen's petitions cannot be used to request FDA enforcement actions such as seizures and injunctions.20 The FDA could therefore deny the petition on these grounds. However, the IACP critique demolishes Wyeth's arguments one by one.

For example, Wyeth's petition invokes statutory provisions that the FDA has never indicated apply to compounding pharmacies. As a result, the company's attempt to apply regulations designed for off-the-shelf, one-size-fits-all pharmaceuticals to the practice of compounding custom-made medications would, as the federal government and Supreme Court have already acknowledged, effectively deny patients access to these medications. That, of course, is Wyeth's intention.

Wyeth's petition suggests that compounding pharmacies are selling bioidentical hormone products directly to ignorant patients. The petition even states that the pharmacies “are simply trying to dupe an unsuspecting patient population.”12 Conveniently ignored is the fact that a licensed medical doctor must write a prescription for a patient to obtain a bioidentical hormone formulation, just as a doctor does when he or she prescribes Prempro®.

According to Wyeth, pharmacies that compound bioidentical hormone formulations are somehow involved in “manufacturing,” and must therefore be brought under FDA jurisdiction. However, bioidentical hormone preparations are customized for each patient—there is no wholesale manufacturing involved, as is implied by the Wyeth petition. Wyeth also suggests that anyone who advertises their services in compounding hormones must therefore be a manufacturer. The Supreme Court has already reviewed this issue, concluding in 2002 that the First Amendment precludes the FDA from using advertising as a factor in its regulations.21 This decision protected the right of pharmacies to advertise the availability of their compounding services. Pharmacies would be “manufacturing” only if they produced large batches of standardized hormone preparations for sale to the public, which they do not.

As if this were not enough, Wyeth's arguments grow even more curious. On the one hand, the company asserts that its drug Premarin®—which is derived from the urine of pregnant mares—is unique and unable to be copied generically.

For more than a decade, Wyeth has fended off generic competition to Premarin® by claiming that an unknown compound found only in horse urine might be a “concomitant component” that is partially responsible for its effectiveness.14 Incredibly, the FDA has accepted this “secret ingredient” argument. At the same time, Wyeth claims that all estrogen drugs hold the same risks and must therefore carry the same black box warnings and other package inserts.

In fact, not all estrogen preparations are alike. By petitioning that all estrogen drugs should carry black box warning labels, Wyeth is essentially implying that the findings of the Women's Health Initiative study apply to all estrogen-based therapies, including bioidentical hormone preparations. In fact, the WHI study examined only Wyeth's products—and not bioidentical hormone replacement therapies.4,5

Moreover, the study was halted in 2002 after the data conclusively demonstrated that using Premarin® (conjugated estrogen) raised stroke risk, while the use of Prempro® (Premarin® plus synthetic progesterone) elevated risk for stroke, breast cancer, heart attacks, and blood clots.4,5 The FDA's own record suggests that if use of a natural product presented even a fraction of these risks, the product would be taken off the market in the blink of an eye. Four years after the WHI study exposed the potentially lethal side effects of Wyeth's hormone products, these dangerous drugs are still widely used.


The FDA's ruling on the Wyeth petition will have wide implications not only for compounding pharmacies, but also for millions of aging women and men who recognize the important role that customized hormone formulations can play in enhancing health and alleviating the effects of aging.

To date, bioidentical hormone replacement has not demonstrated the same health dangers that the WHI study attributed to Wyeth's hormone drugs. While bioidentical hormone therapies have not been subjected to randomized, prospective clinical trials to assess their risks, many doctors and patients are convinced that bioidentical hormones are both safer and more effective than hormone drugs, since they contain hormones that are identical to those found naturally in the human body. Many women who commented on the Wyeth petition felt compelled to share personal stories about how bioidentical hormones helped alleviate their menopausal symptoms and greatly improved the quality of their lives.

As Dr. Taylor of Emory University points out, “I don't need a double-blind study to simply bring hormones back to their normal levels. We know what progesterone does to the body. We don't have to prove what a bioidentical hormone does, because it is not foreign to the body.”

Until conclusive scientific evidence demonstrates that bioidentical hormones carry the same risks as commercial hormone drugs, the FDA should reject Wyeth's request that bioidentical hormone formulations carry the same warnings required of its own disease-inducing drugs. Furthermore, given the wealth of clinical and anecdotal studies demonstrating the life-enhancing benefits of optimal hormone balance,1-3 ensuring that Americans continue to have access to compounded bioidentical hormones should be a top priority for all who seek optimal health and well-being.
