61 dilate arteries and improve blood flow." The ongoing Kronos Early Estrogen Prevention Study (KEEPS) is a clinical trial comparing the effect of conventional vs. bioidentical hormones (oral vs transdermal) on the development and progression of atherosclerosis, cognitive function, and quality-of-life outcomes in recently menopausal women. 2 " But no large-scale trials have been undertaken-or are currently planned-to provide a head-to-head comparison of bioidentical versus traditional hormones in terms of their effects on hard clinical outcomes such as heart attack, stroke, or breast cancer. Dangers with over-the-counter products Over-the-counter products that contain bioidentical hormones may carry real health risks and should not be used without supervision by a qualified clinician. Among such products are skin creams that contain bioidentical progesterone. Doctors routinely prescribe progesterone for women who take estrogen to protect against possible overstimulation of the uterine lining, which could lead to uterine cancer. Existing data on progesterone skin creams are not consistent as to how much progesterone is absorbed; moreover, such preparations are often not standardized. Thus, it's hard to know exactly how much progesterone one may be getting. Progesterone skin creams may not adequately protect the uterine lining and should not be used for this purpose. Some naturopaths and medical authors (most notably the late Dr. John Lee, whose hormone books have been recent best-sellers) advocate using progesterone cream alone, without estrogen, to relieve hot flashes and other menopausal symptoms. However, there has been little research on whether it's effective in doing so, and, more importantly, no research on potential long-term risks of this approach. 1, along with the majority of doctors, don't recommend it. Of concern, such products are widely available without a doctor's prescription over the Internet. Although classified as a cosmetic by the FDA, progesterone skin creams may produce similar exposure levels in the body as prescription oral progesterone (research is limited and contradictory on this point) and may confer similar long-term health risks, although no rigorous research has been conducted on this subject. It's a dangerous practice to use this product, or any hormone product, without a doctor's supervision An over-the-counter product marketed as "wild yam cream" contains an inactive precursor of progesterone that cannot be metabolized by the human body. Given that it contains no active hormones, wild yam cream is not likely to cause harm-but it won't help with menopause symptoms and it can be expensive. Summary The prudent policy recommended by all major medical organizations is, in the absence of scientific evidence from well-designed studies comparing various forms of hormone therapy, is to operate on the assumption that all postmenopausal hormone formulations confer similar risks and benefits. However, many proponents of custom-compounded bioidentical hormones are making unsubstantiated claims of superiority that run directly counter to this policy. Given this pervasive and misleading marketing, I have a deep concern that women-and even some of their
62 doctors-are not getting the objective information necessary to make well-informed choices about hormone therapy. There is an urgent need for (a) increased regulatory oversight of customcompounded bioidentical hormones, as provided for traditional hormone therapy, including assessment of purity and dosage consistency; (b) inclusion of uniform patient information about risks and benefits in the packaging of these products; (c) mandatory reporting by drug manufacturers and compounding pharmacies of adverse events related to these hormones; and (d) clinical trials testing the safety and efficacy of these products...Thank you very much for your consideration of these issues and I'd be pleased to answer any questions.
