Dr. Wilcox specializes in prescribing natural bioidentical hormone replacement for the treatment of women’s hormonal imbalances, such as those that occur in menopause and perimenopause. Dr. Wilcox has been preaching the superior benefits and safety of bioidentical hormones vs. synthetic hormones for many years. There are many health care providers that now claim to specialize in natural hormones but Dr. Wilcox’s expert training, knowledge, and experience as a board-certified MD who has been in practice for over 25 years can make the difference between feeling great and just so so.
The ovaries, testicles and the adrenal glands manufacture a series of hormones all derived from cholesterol. These are called the steroid hormones. Since the early 1960s, chemists have been able to synthesize all of these molecules starting either from cholesterol or from plant steroids found in wild yams and soy. Since the manufactured molecules are exact duplicates of the hormones made by the various glands in the body, they are called bioidentical.
There are three estrogens made by the ovaries. They are Estradiol (the strongest of the three), Estrone (of intermediate strength), and Estriol (the weakest but safest). The ovary and the placenta make progesterone. On the male side is testosterone. The adrenal gland makes two weaker androgens, DHEA (dehydroepiandrosterone), and androstenedione as well as cortisol. Actually, ovaries, testicles and adrenal glands can all make any of these hormones, although the quantities vary. The thyroid hormones, T4 and T3, are bioidentical. Synthroid and Levoxyl are T4 and Cytomel is T3. Humalog is a manufactured hormone identical to human insulin. All of these hormones, as well as some others, are available for purchase at a pharmacy through a doctor’s prescription.
Many pharmaceutical companies have developed and manufacture hormones that have been altered with some chemical groups added or removed. These hormones are different from anything the body naturally makes. They are not identical to anything naturally occurring in a human body.
Some of these chemical changes make the hormones better absorbed when taken by mouth. Some changes make the hormones stronger or last longer. Some changes alter the hormones effects. Birth control pills are all synthetic. The estrogens in birth control pills are better absorbed by mouth than natural estrogen. Natural progesterone requires relatively large quantities to work. Most birth control pills use an altered form of testosterone, which acts in some ways like progesterone. The drug companies call these chemicals Progestins. They are better absorbed by mouth than real progesterone, are stronger and last longer, so less is needed and the pills are smaller. As they are foreign to the human body, they tend to have greater side effects. In addition, a manufacturer can get a patent on a newly created molecule and thus sell the patented drug for more money. Natural occurring bioidentical hormones cannot be patented.
Yes. All hormones available at the compounding pharmacist are FDA approved. They require a doctor’s prescription with instructions to the pharmacist as to the form of the medication, dosage and how it is to be used.
For a manufacturer to produce and advertise a medication, they must first prove to the FDA that each particular dosage form, strength and use will perform according to their advertising, be safe and effective. This costs the manufacturer a huge amount of money. They patent their new drugs and hope that they will pass the FDA and sell enough to make back their investment plus a profit. While under patent, no one else can make or sell their drug.
You can’t patent parts of the human body. Once any drug or dosage form is approved by the FDA, any company can make and sell a generic, unless the drug is protected by a patent. Without patent protection, it simply does not make business sense for any manufacturer to spend the money getting specific dosage forms through the FDA.
Yes. Estrogen patches, for the most part, use real bioidentical estradiol. The manufacturer has patented the patch itself, not the hormones inside. Prometrium is a drug company product that is real progesterone mixed by a patented process with peanut oil. The peanut oil mixture is what is patented. It comes in only two dosages, but is available at any drug store and is covered by most insurance. Of thyroid hormones, Synthroid is real T4 and Cytomel is real T3. Thyrolar is a combination of T4 and T3 in a 4 to 1 ratio.
Hormones at a compounding pharmacy are real, bioidentical hormones. They can be put into oral capsules or tablets, skin cream, vaginal cream, oral troches, vaginal suppositories, or liquid drops and in any dose the doctor chooses. Different patients have individual needs and preferences. Most manufactured medications like Prometrium come in only one form and only a couple of doses. Forty years ago, before there were big chain drug stores, all pharmacies were compounding pharmacies. Most prescriptions were blends of medications or herbs created by doctors and pharmacists, and prepared by the pharmacist for the individual patient. Since this is time consuming, chain drug stores have chosen to sell only pre-manufactured medications. Since bioidentical hormones are body parts, they cannot be patented. Manufacturers have no financial incentive to get multiple dosages and forms through the FDA, so they cannot be mass produced and distributed in chain pharmacies.
Through evolution, the human body has developed the ability to regulate, break down and excrete natural bioidentical hormones. Synthetics do not act in exactly the same way as the natural hormones. Laboratory tests are available to measure levels of the bioidentical hormones. Most synthetics cannot be easily measured. In addition, the normal levels of most real hormones are known. What would be the “normal” levels of synthetic hormones?
Prior to starting on hormone therapy, the patient’s own hormone levels are measured. Dosage and form of therapy are chosen based on each individual patient’s needs and preferences. Once the patient has been on the therapy for a period of time, levels can be measured again and the dosage adjusted or the route of administration changed, to suit the patient’s individual needs. Doctors have been treating thyroid disease, diabetes and electrolyte imbalance in this manner for many years. The object is to get the patient back into balance using bioidentical replacement products and using each patient’s symptoms and laboratory levels as a guide.
