We are excited to share our PRESCRIBER FORUM monthly newsletter with you and look forward to working with you. Please don't hesitate to let us know how we can assist you and your practice. LeAnn Chambers, Pharm.D. and Matthew Chambers, Pharm.D. The Value of Compounded Bioidentical Hormone Therapy After the results of the Women’s Health Initiative trials were first published in 2002, patient and professional interest in potential options to conventional hormone therapy grew, and the number of prescriptions for compounded hormones (cBHT) significantly increased. Compounding is the preparation of a custom formulation of a medication to fit a patient’s unique needs which cannot be met with commercially available products. Estradiol, estriol, progesterone, and testosterone have been widely used and clinically accepted internationally since the 1940s, both as manufactured products and compounded preparations. Millions of women rely on bioidentical hormones for menopausal issues, fertility challenges, and other hormonal imbalances, and men benefit from therapy as well. Even though there have been dozens of hormone-containing products evaluated for safety and efficacy and approved by the FDA, there is still a need for individual compounded preparations for millions of patients. Compounding permits the dose, dosage form, and route of administration to be customized and titrated to obtain the desired clinical effect in each individual patient while minimizing any potential side effects. This is why so many patients prefer cBHT as compared to manufactured products available only in limited dosage forms and strengths. Many, if not most, patients have already tried FDA-approved products without the desired clinical response and so they change to cBHT. These patients have a significant therapeutic https://app.constantcontact.com/pages/campaigns/email-details/details/activity/389b5f0f-0a1f-4b63-97a5-bbf6ed295a6c 1/3 2/8/2021 Constant Contact need and often compliance and outcomes can improve with customized medications. QUALITY COMPOUNDING For decades, pharmacists around the world have compounded cBHT using the highest quality ingredients which are identical to those used in manufacturing FDA-approved products. Pharmacists are required to compound from an existing FDA-approved drug product or use bulk drug substances known as active pharmaceutical ingredients (API) that meet US Pharmacopeia-National Formulary (USP-NF) standards in applicable monographs. USP is a non-profit organization that sets standards for the identity, strength, quality, and purity of ingredients used to make drugs. HORMONE TESTING Many compounding pharmacists recommend and health care providers prescribe saliva or serum testing to confirm that dosing of cBHT is appropriate to maintain therapeutic levels and reduce the risk of side effects from excessive doses. There are often misconceptions regarding the most accurate way to test for hormone levels and the variation between salivary, capillary, and serum/plasma hormone concentrations based on the route of administration of the hormones (topical, oral, or parenteral). “Measurement of extremely low levels of hormones such as E2 [estradiol] in saliva requires a modification to the assay such as a preceding purification step. For example, ZRT Laboratory in Beaverton, OR utilizes an extraction step to purify E2 prior to its quantification by an antigen-excess enzyme immunoassay (EIA).”1 “The accumulation of topically administered progesterone in body tissues in the absence of a demonstrable change in serum levels strongly suggests that salivary levels of progesterone are more clinically relevant than serum levels in women using topical progesterone creams… In contrast to salivary E2 levels, the levels of progesterone are considerably higher and can be measured by a well-validated EIA. Salivary progesterone levels are approximately 10-fold greater than those observed in serum in postmenopausal women treated with an 80-mg dose of topical progesterone cream. Thus, tissue levels of progesterone may be very high, but this is not reflected in [serum] levels. This is a concern because progesterone is transformed into many metabolites, some of which are active, e.g. neurosteroids such as allopregnanolone. Therefore, excessive intake of progesterone may cause adverse effects such as hormonal imbalance and mood swings.1 In January 2021, Townsend Letter published an article by David T. Zava, Ph.D. which noted "The use of saliva and finger-prick capillary blood (dried blood spot – DBS) for testing sex steroid hormones (estradiol, progesterone, testosterone) was developed out of the need to circumvent some of the problems and inconveniences of collecting venipuncture blood. Comparison of saliva and capillary DBS has shown that when these hormones are produced endogenously, they show excellent correlation with serum/plasma tests and to some extent urine sex steroid metabolites. While the quantitative equivalencies of saliva, capillary blood, and serum/plasma are excellent when hormones are produced endogenously, we and others have shown that with topical (percutaneous) delivery of sex hormones, saliva and capillary DBS levels of hormones are strikingly different from conventional venipuncture serum and urine levels of the supplemented hormones. Topical steroid hormone therapy with increasing dosage results in very little, or only a very slight, dose-related increase in conventional venipuncture serum or urine metabolite levels of the dosed hormone. In striking contrast, topical dosing results in a relatively linear dose-dependent escalation of hormone in saliva and capillary blood DBS… Most noteworthy and often unappreciated is that physiological dosing with the sex hormones, meaning that the dose used topically is equivalent to the amount of sex hormone produced daily by the ovaries, testes, and/or adrenal glands, leads to physiological levels in saliva and capillary blood, but has little effect on increasing serum or urine levels from low menopausal/andropausal to healthy levels seen in young females and males... From pharmacokinetic studies, we know that when a steroid hormone is delivered as a cream or gel to the surface of the skin, it takes about two-to-six hours before it peaks in saliva or capillary blood from the fingertip, and then begins to slowly decline to baseline within 12-36 hours." 2 NASEM REPORT The FDA commissioned a study from the National Academies of Sciences, Engineering, and Medicine (NASEM) on the safety, effectiveness and use of cBHT. The study committee included respected healthcare professionals but did not include a pharmacist with patient- facing experience, a compounding pharmacist, or a physician with substantive experience in https://app.constantcontact.com/pages/campaigns/email-details/details/activity/389b5f0f-0a1f-4b63-97a5-bbf6ed295a6c 2/3 2/8/2021 Constant Contact BHT. The peer reviewers included one former FDA employee (and current FDA contractor) who is a long-time, well-known opponent of pharmacy compounding.3 NASEM recommended “that prescribers restrict the use of cBHTs to two circumstances: when a patient is allergic to an ingredient in an FDA-approved hormone product, and when a patient requires a specific dosage form not available for an FDA-approved product.”4 Loyd V. Allen, Jr., PhD, RPh, Editor-in-Chief of the International Journal of Pharmaceutical Compounding, responded that “when one looks at the conclusions of the NASEM report, it is apparent that many of these are the requirements for mass-manufacturing of FDA-approved drugs and not for an individual patient. Even though there have been dozens of hormone- containing products evaluated for safety and efficacy and approved by the FDA, there is still a need for individual compounded preparations for millions of patients… One needs to consider enhancing patient compliance and outcomes using various dosage forms, patient-specific doses and dose variations, different routes of administration, [and] different product components to achieve the patients desired response, etc… It should also be noted that cBHT formulations have been successfully compounded for decades and are not difficult to compound.”5 We know that FDA-approved therapies do not meet the therapy goals of many patients and that limiting access to cBHT as NASEM recommends would have far-reaching consequences for many patients.

  • Compounded Drugs
    Compounded Drugs Judith M. Glassgold Specialist in Health Policy June 3, 2013 Congressional Research Service 7-5700 www.crs.gov R43082 CRS Report for Congress Prepared for Members and Committees of Congress Compounded Drugs Summary Compounding has been traditionally defined as a process where a pharmacist or a physician combines, mixes, or alters ingredients to create a medication tailored to the needs of an individual patient. Traditionally compounded drugs (CDs) are made in response to an individual prescription from a licensed health provider in the context of a pharmacist’s and health care professional’s relationship with a specific patient. Some have suggested that certain activities not traditionally associated with compounding be considered compounding. Such activities include the large-scale production of drugs to ease certain drug shortages, to meet outsourcing needs of hospitals, and to supply physician- administered drugs. Non-traditional compounding may include (1) the production and shipping of large volume of drugs across state lines; (2) production of drugs that are copies of FDA-approved commercially available drugs; (3) provision of CD without a prescription for an individual patient to receive a compounded version and outside of a professional relationship; and (4) production of products to third parties, such as hospitals, clinics, physician offices, and home health providers. These activities could be considered more akin to manufacturing than traditional compounding, which is considered part of the traditional practice of pharmacy. Adverse events involving contaminated compounded drugs have drawn attention to the growing use of non-traditionally compounded drugs in health care delivery. Shortages of sterile generic drugs and hospital outsourcing are cited as causes of increased numbers of CDs produced by non- traditional compounders.

Hassan Murad, MD, MPH; Christian J. Nelson, PhD; Elizabeth A. Platz, ScD, MPH; Lakshmi V. Ramanathan, PhD; Ronald W. Lewis, MD Executive Summary Testosterone testing and prescriptions have nearly tripled in recent years; however, it is clear from clinical practice that there are many men using testosterone without a clear indication.1-3 Some studies estimate that up to 25% of men who receive testosterone therapy do not have their testosterone tested prior to initiation of treatment.2, 3 Of men who are treated with testosterone, nearly half do not have their testosterone levels checked after therapy commences.2, 3 While up to a third of men who are placed on testosterone therapy do not meet the criteria to be diagnosed as testosterone deficient,2, 3 there are a large percentage of men in need of testosterone therapy who fail to receive it due to clinician concerns, mainly surrounding prostate cancer development and cardiovascular events, although current evidence fails to definitively support these concerns. Given the clinical and commercial testosterone landscape, the American Urological Association (AUA) identified a need to produce an evidence-based document that informs clinicians on the proper assessment and management of patients with testosterone deficiency.

  • Clinical Pharmacology
    Testosterone Drug Description NOTE: Testosterone is a schedule C-III controlled substance. Testosterone is the primary androgen found in the body. Endogenous testosterone is synthesized by cells in the testis, ovary, and adrenal cortex. Therapeutically, testosterone is used in the management of hypogonadism, either congenital or acquired. Testosterone is also the most effective exogenous androgen for the palliative treatment of carcinoma of the breast in postmenopausal women. Anabolic steroids, derivatives of testosterone, have been used illicitly and are now controlled substances. Testosterone was in use in 1938 and approved by the FDA in 1939. Testosterone is administered parenterally in regular and delayed-release (depot) dosage forms. Two transdermal forms are available for the treatment of male hypogonadism. Testopel® Implants contain testosterone in sterile pellets that are implanted subcutaneously for extended-release over 3—6 months. Two testosterone topical skin gel products are available: Androgel®, approved in February 2000, and Testim™, approved October 31, 2002. A testosterone buccal system (Striant™) was FDA approved in July 2003; the system is a mucoadhesive product that adheres to the buccal mucosa and provides a controlled and sustained release of testosterone. Other topical dosage forms are under investigation, including a transdermal patch (Intrinsa™) for hormone replacement in women; the daily dosages used for testosterone replacement in women are much lower than those found in products for use in males. However, the FDA ruled in late 2004 that it would delay the approval of Intrinsa™ women's testosterone patch and is requiring more data regarding safety, especially in relation to cardiovascular and breast health. Testosterone was reclassified as a controlled substance in 1991.

Gillson, MD, PhD Rocky Mountain Analytical, Calgary, Alberta, Canada David T. Zava, PhD ZRT Laboratory, Portland, Oregon Note: In this article, bioidentical hormone replacement therapy will be referred to as BHRT, and conventional hormone replacement therapy will be referred to as CHRT.
