Choosing a Dosage Form for Compounded BHRT

Choosing a Dosage Form

for Compounded Bioidentical Hormone Replacement Therapy

Written by Carol Petersen, RPh, CNP – Women’s International Pharmacy

row of doorsOne of the truly wonderful things about using compounded bioidentical hormone therapy is the opportunity to choose from a wide array of dosage forms. A “dosage form” is the manner used to deliver a medication into the body, such as capsules, creams, lozenges, gels, suppositories, and drops. Women’s International Pharmacy offers many choices of dosage forms in order to help meet each individual’s specific needs.

Oral Dosage Forms

Capsules are convenient to use. They are quick and easy to take, and multiple hormones can be combined into one capsule, allowing for increased individualization and ease of use. Women’s International Pharmacy pioneered compounding hormones mixed with an edible oil inside a capsule. These oil-based capsules were based on original research with progesterone done by Drs. Hargrove and Maxon. They demonstrated that micronization, or reducing the particle size of the hormone powders, and mixing the powders in oil inside the capsule allowed for good absorption of hormones like progesterone.

Sex and adrenal hormones mixed with oil are absorbed into the body from the intestinal tract and transported via chylomicrons (particles that transport fats throughout the body) through the lymphatic system. This allows the hormones to avoid extensive destruction by the liver on their first pass through the body, and may increase the amount of drug available for use by the body. Some criticize using capsules with hormones orally, citing that the hormones are broken down by stomach acids. This is true of hormones that are protein-based, but not those that are related to cholesterol like most sex and adrenal hormones.

Progesterone taken orally in a capsule may cause drowsiness for some individuals. This occurs when progesterone is broken down by the body into other substances called metabolites. Some of these metabolites may have a sedative effect for some. Practitioners may deliberately prescribe progesterone at bedtime for patients having trouble falling asleep hoping the patient experiences the drowsy effect.

Capsules might not be a first choice for individuals who have problems with their digestive tract. However, because the hormones are dispersed in oil inside the capsule, a practitioner may direct their patients to open the capsule and use the hormones and oil directly on the skin.

Transdermal Dosage Forms

Hormones may be applied to the skin in creams, gels, ointments, lotions, sprays, and drops. Patches are also available commercially from drug manufacturers. Most transdermal dosage forms allow for multiple hormones to be combined together for ease of application. Transdermal dosage forms also allow the flexibility to use varying amounts of the medication to adjust the dose based on a practitioner’s directions.

The skin usually acts as a barrier that prevents substances from entering the body, but cholesterol-based hormones can travel through hair follicles and make it past the outer skin layer into the blood and tissues. A common misconception when dosing hormones transdermally is that the amount of hormone applied is the amount absorbed. It has been estimated that only 10-80% of the hormone applied in a cream is actually absorbed. With such a large range, it is easy to see why doses may vary for individual patients. Additionally, absorption through the skin may be compromised for people who have impaired blood flow to the skin, such as those diagnosed with hypothyroidism, or low thyroid function.

It can also make a difference where on the skin the hormones are applied. Hormones can easily get through hair follicles but very hairy areas could interfere with the dosage form coming into contact with the skin. The part of the body where the hormones are applied may have a higher temporary level of hormones available to the hormone receptors in that area. This can be important if treating a specific area such as the eyes or vaginal area.

When using transdermal dosage forms, it is important to take steps to ensure the hormones aren’t transferred to other individuals through direct (touch) or indirect (laundry, door handles, bedding) contact. Wash hands with soap and water after applying the medication and avoid person-to-person and person-to-pet contact with application sites.

Sublingual Dosage Forms

Sublingual dosage forms are placed under the tongue or between the cheek and gum to allow the hormones to be absorbed through the tissue of the mouth into the body. However, part of the dose should be considered to be an oral dose as it would be very difficult not to swallow any of the dose.

Sublingual use tends to raise the blood levels of the hormones quickly and to a higher level than the hormones delivered in oral capsules. Sometimes these enhanced levels are useful. Sublingual estradiol is sometimes used to rapidly relieve headaches triggered by low estrogen levels, and lozenges have been used 4-8 times daily to mimic the surges in testosterone that young men naturally experience throughout the day.

Lozenges and drops are examples of sublingual dosage forms. Lozenges are prepared by placing hormones in a tablet like form that dissolves easily in the mouth. Drops are made by suspending or dissolving the hormone powder in an edible oil or other liquid. Drops can be used under the tongue or on the skin. It is important to shake the drops vigorously before use so the hormones are evenly distributed.

The drop dosage form is ideal for very sensitive patients because the hormones can be suspended in an edible oil with no other ingredients added. One can determine if the hormone itself is presenting an issue or if it is the presence of other ingredients. Taste can be an issue when using sublingual dosage forms; however, compounding pharmacies can help by adding flavors and/or sweeteners if desired.

Vaginal or Rectal Dosage Forms

Hormones may be inserted vaginally or rectally in suppositories, capsules, creams and gels. The vaginal and rectal routes can be used to distribute the hormones throughout the entire body, but may also be used when a direct effect is desired at the site of application. For example, the rectal route may be used to relieve hemorrhoid symptoms and the vaginal route may be used to relieve symptoms of vaginal atrophy and dryness.

Conclusion

For many people, any one of the dosage forms described above will work well, and the deciding factor is purely preference. Others—whether due to sensitivities, absorption issues, or something else—may need to try a number of dosage forms before finding the one that works best for them. Women’s International Pharmacy is here to help patients and practitioners sort through the options and make the best choice for each individual.

Medication Disposal Tips

Medication Disposal Tips

Written by Kathy Lynch, PharmD– Women’s International Pharmacy

 

April is the time of year when our thoughts turn to spring. Earth Day was first celebrated on April 22, 1970. Forty-five years later, it continues to be a time when we focus our attention on the earth and the protection of our environment, including our groundwater. Waste water treatment plants are not effective in keeping medications from polluting our water system.

Drug disposal options expanded last fall when the US Congress amended the Controlled Substances Act of 2010. People who have unused or expired controlled substances, as well as other oral or topical medications, and OTCs including vitamins, may now return them to their local pharmacy, clinic, or any other agency that has a medication disposal program in place. The Drug Enforcement Administration (DEA) also changed the rules so that people may mail-in unwanted medications to collectors that destroy the drugs by incineration which is the disposal method of choice. The DEA used to sponsor national medication take-back events twice a year but is now shifting that responsibility to local communities.

If an individual’s current pharmacy does not have a drug disposal program, call your local police department or go to their website. You can also search for local community programs by using the terms “medication drop boxes,” “medication disposal,” or “safe community programs.” If there isn’t a program near you, follow government guidelines for medication disposal (FDA Regulations and USEPA)

Women’s International Pharmacy jars, topiclicks, vials, lids, dropper bottles, and droppers are recycle number 5. Tubes are number 41. Please follow your service area’s guidelines when recycling medication containers. Keep in mind Women’s International Pharmacy does not accept medicines for disposal and suggests you follow the federal guidelines.

The Evolution of Compounding

The Evolution of Compounding:
Where Are We Now? How Did We Get Here?

Written by Carol Petersen, RPh, CNP – Women’s International Pharmacy

In primitive societies, the healing arts were a combination of sorcerer, priest, and medicine man—someone armed with magic rather than medicine. As practices of pharmacy and medicine evolved, the preparation of “therapies” often predated even the naming of the therapy. Ancient healers may have known “what” substances to use, but lacked the knowledge and equipment to understand “how” or “why.”

Developments in Ancient Medicine

Some of the earliest medical texts were written around 2100 B.C., describing the use of oils, alcohols, wines, fats, honey, and more as remedies for various ailments. A 7th century B.C. collection of remedies provides evidence of approximately 250 drug substances of vegetable origin, 120 of mineral origin, and 180 of other origins.

Fast forward to the Persian world where vast medical developments involved the weighing and measuring of materials and the introduction of syrups, confections, and plant oil extractions. The physician and philosopher Avicenna unified all known medical science into The Canon of Medicine in 1025 A.D. Translations of this text into Latin eventually brought this knowledge to the western world.

Medicine and pharmacy (as well as other practices) have their roots in the medieval guild system, which protected artisans with a particular expertise from competition or exploitation. Guilds also served to enforce standards of their respective crafts. In 1240 Emperor Frederic II of the Holy Roman Empire decreed that the guilds of pharmacy and medicine would be separate, a division of authority that would prove to have long-reaching consequences.

Pharmacy in Industrial America

The practice of pharmacy continued in essentially the same way until the Industrial Revolution. Rapid advances in technology greatly impacted pharmacy, as some medications lent themselves to the increased efficiencies of manufacturing. These products could be manufactured identically and in larger quantities, making the process less expensive and more easily standardized compared to medications made for specific patients’ needs.

In 1820, the United States Pharmacopeia (USP) was established to promote the standardization of formulas. While compounding was still the most prevalent way of formulating medications, it became less common as the pharmaceutical industry began providing standardized doses and dosage forms.

Another benchmark in the evolution of pharmacy in the U.S. occurred in the 1870s, when patent and trademark laws allowed companies to advertise to ensure the creation of markets for manufactured products. Unfortunately, anything could be promoted and advertised without needing to verify its effectiveness. This led to the passage of the first Pure Food and Drug Act in 1906, which was later replaced by the Food, Drug and Cosmetic Act in 1938. Among other things, the Pure Food and Drug Act prevented mislabeled and contaminated products from being sold in interstate commerce.

Patent Medicines Gain Prominence

The first third of the twentieth century ushered in more radical changes in manufacturing that affected the practice of pharmacy. Chemistry and biochemistry had advanced such that new molecular entities could be created. The emergence of antibiotics, chemotherapeutic agents, hormones, radioactive agents, and vaccines created new fields in pharmaceutical science. While pharmacists were still using a broad knowledge of compounding to serve their customers, by the 1920s the so-called “patent medicines” accounted for approximately 20% of their business.

The traditional art of compounding began to fade away. By the 1960s, the concept of a “clinical pharmacy” had taken hold. Pharmacists became more focused on dispensing drug products in consultation with patients and practitioners, rather than being tied to creating preparations. Compounding coursework was minimized or eliminated from the professional curricula. Many in the profession considered compounding to be outmoded.

A Compounding Renaissance

The formation of the Professional Compounding Centers of America (PCCA) in 1981 arose from the recognition that manufactured medications could not always meet individual patients’ particular needs. Some pharmacists embraced the challenge of individualizing treatments instead of dispensing manufactured, one-size-fits-all medications.

Revolutionized technology accompanied this resurgence of compounding. The tools for compounding pharmacists evolved beyond mortars, pestles, and balances to automated mixing devices and precision electronic balances, allowing for the creation of smaller batches of individualized preparations.

The FDA and Other Challenges

The compounding revival encountered its first sign of things to come in 1989 with an internal document from the Food and Drug Administration (FDA), stating its intention to regulate pharmacy compounding. By 1992, the FDA issued its first Compliance Policy Guide regarding compounding and began to inspect pharmacies.

To sidestep the limitations imposed by statute, FDA inspectors enlisted the aid of state pharmacy inspectors to conduct their visits. The FDA applied regulations intended for manufacturers to compounding that were  not legally required and not appropriate in the context of a pharmacy. The results of these inspections were often citations and warning letters.

The FDA Modernization Act (FDAMA) of 1997 extended regulations to allow FDA oversight of pharmacy compounding. In the following years, a profusion of lawsuits, petitions, and challenges ensued before pharmacy and medical boards, Congress, the FDA, and consumer groups. The compounding pharmacy industry responded by forming the International Academy of Compounding Pharmacists (IACP), to represent their segment of pharmacy practice. On April 29, 2002, in Thompson vs Western States Medical Center, the Supreme Court of the United States held FDAMA’s prohibitions on soliciting prescriptions for, and advertising, compounded drugs amounted to unconstitutional restrictions on commercial free speech.

Traditionally, healthcare practice had been the responsibility of individual states to regulate, so the FDA’s actions were unprecedented in that a federal agency was crossing into the states’ regulatory arena. Many states made changes in their Pharmacy Practice Acts to include regulation of pharmacies that sent prescriptions into their states. The USP made changes to their compendia, in addition to making their recommendations for processes and procedures enforceable upon the practice, particularly upon pharmacy compounding. Professional pharmacy organizations also came together to found the Pharmacy Compounding Accreditation Board (PCAB), a voluntary quality accreditation for the compounding industry, now offered by the Accreditation Commission for Health Care (ACHC).

Yet regulations and safeguards did not prevent the tragedy that occurred between May and October of 2012. The New England Compounding Center (NECC) sent out preparations that infected patients with fungal meningitis and caused over sixty deaths. It was established later that NECC was operating in violation of the Massachusetts Pharmacy Practice Act by sending thousands of vials of methylprednisolone to practitioners and hospitals without patient-specific prescription orders.

Both the State of Massachusetts and the FDA had previously inspected and found problems with NECC, and both had failed to take action. Many in the industry pointed out that adequate regulation was already in place—the regulators had simply neglected to enforce it. In spite of this, there was still a public outcry for more regulation of compounding pharmacy.

New Regulations & New Questions

The Drug Quality and Security Act (DQSA) was signed into law on November 27, 2013, to amend the Food, Drug and Cosmetic Act. Many of the provisions of the earlier act under FDAMA were restored, including but not limited to:

  • Tasking the FDA with creating lists of substances which may or may not be compounded. In order to develop this list, the FDA was instructed to create and consult an advisory committee on compounding.
  • Determining if a Medication is “Too Difficult to Compound.”
  • Establishing the difference between 503A pharmacies (traditional compounding pharmacies) and 503B facilities (“outsourcing facilities” under FDA oversight that compound non-patient specific sterile preparations to be sent directly to hospitals and practitioners).

The intent of Congress in passing this act was to prevent future incidents such as the one that happened at NECC. Congress did not propose to eliminate access to consumers for office-administered therapies, to restrict shipping of patient specific medications across state lines, or to have the FDA inspect compounding pharmacies using regulations intended for manufacturers. In fact, Congress made their intent perfectly clear with language included in the Congressional Omnibus bill, HR244, that was signed into law in May 2017 (see box on the right, Summary of Congressional Omnibus Bill HR244). However, the FDA continued to ignore congressional intent in its application of the DQSA.

In spite of the fact that Congress has instructed the FDA to release new guidance to allow 503A pharmacies to compound for office use, and that some states already have regulations permitting the compounding of medications for practitioners to administer to patients in their offices, the FDA continues to contend that this is not allowed.

Another area of concern is the Pharmacy Compounding Advisory Committee (PCAC) the FDA created to consult when determining the list of substances which may or may not be compounded. The DQSA requires this committee to include representatives from the National Association of Boards of Pharmacy, the USP, as well as pharmacy, physician, and consumer organizations, and other experts selected by the FDA. At the time of this writing, the Pharmacy Compounding Advisory Committee includes only one compounding pharmacist in a non-voting position.

Yet another issue is the recent restoration of the FDA’s charge to create memoranda of understanding with each state. This will determine the conditions governing the rights of compounding pharmacists to send their preparations into another state. Without a memorandum in place, the law limits the distribution to 5% of total prescription orders distributed. With a memorandum in place, a state could only allow distribution up to 30%. The FDA contends that this limitation applies to patient-specific medications as well as medications compounded to be used for office use, even though the term distribute should not apply to patient-specific medications.

Summary of Congressional Omnibus Bill HR244

The language included in HR244, signed into law in 2017, calls on FDA to do the following:

  • Draft a new memorandum of understanding that does not include “dispensing” within the MOU.  Congress expressed concern that the FDA draft MOU includes both “dispensing” and “distribution” of compounded medications.  Congress made clear in the language that FDA does not possess this authority and specifically stated, “Congress only allowed the FDA to regulate distribution” under the MOU and “Congress did not intend to include dispensing of compounded drugs over state lines within the scope of the MOU.”
  • Release new guidance to allow 503A pharmacists to compound for “office-use” for prescribers, hospitals and other health systems.  Congress expressed concern that patient access is decreasing to compounded medications, due to FDA’s implementation actions of prohibiting all office-use compounding even where “this practice is authorized in the vast majority of states and was intended to be allowable under DQSA.”
  • Cease inspecting state-licensed 503A pharmacies under current Good Manufacturing Practices (cGMPs).  Congress instructed FDA to inspect 503A pharmacies under USP standards or other applicably pharmacy inspection standards adopted by state law or regulation. Congress also stated that it “reminds the FDA that compounding pharmacies are not drug manufacturers, but rather, are state licensed and regulated health care providers that are inspected by state boards of pharmacy pursuant to state laws and regulations.”  Congress further stated, “compounding pharmacies are more appropriately inspected using USP standards or other pharmacy inspection standards adopted by state law or regulation in the state in which a pharmacy is licensed.”

In short, Congress has clearly stated that the FDA is misinterpreting the DQSA in compounding policies and overstepping their regulatory authority, and directs the FDA to change their DQSA policies to align with statute and the congressional intent expressed in the report.

Lastly, the FDA continues to inspect and issue citations and warning letters based on current Good Manufacturing Practices (cGMPs), even though compounding pharmacies are not drug manufacturers and should not be inspected as such.

However, there may be a light at the end of the tunnel. On June 12, 2017, Congressmen Morgan Griffith (VA) and Henry Cuellar (TX) introduced HR 2871, Preserving Patient Access to Compounded Medications Act of 2017 (see box below, Urge Your Representatives to Cosponsor HR2871). This important bill is a bipartisan effort that will preserve patient access to vital compounded medications and help clarify the DQSA in a way that will better align the statute with congressional intent and better balance public safety and patient access. The bill is currently in the Subcommittee on Health in the House of Representatives and had 42 cosponsors as of the time of this writing.

Compounding Pharmacies in the Present Day

As pharmacy law changes, the practice of compounding will also evolve. The USP has already begun standardizing some of the most commonly-used formulas. Compounding pharmacists bridge an important gap by preparing formulas that manufacturers are temporarily unable to supply (or choose not to supply because they don’t generate enough profit).

The practice of pharmacy compounding is geared up with twenty-first century technology, and compounding pharmacists stand ready for the challenges ahead. Methods of healing have changed dramatically throughout history, and yet the primary goal is the same. From the ancient medicine man to today’s physicians and pharmacists, the health of the patient always comes first.

Urge Your Representatives to Cosponsor HR2871

The Preserving Patient Access to Compounded Medications Act of 2017 (HR2871) will:

  • Provide the records and registration exemptions provided to pharmacies under the Food Drug and Cosmetic Act (FDCA) when inspected by FDA to compounding pharmacies that are compliant with state and local pharmacy laws and 503A of the FDCA.
  • Allow for “office-use” compounding of medications where authorized by state law.
  • Allow for compounding with dietary supplements that comply with the monograph standards of the US Pharmacopoeia or National Formulary.
  • Prevent FDA regulatory authority over interstate “dispensing” of compounded medications pursuant to prescriptions for identified patients, which is left to state law and state boards of pharmacy.
  • Require FDA to follow formal rule-making procedures that allow stakeholder input and decrease confusion by providing formal FDA procedure and statements on the record. Currently, FDA is issuing “guidance documents” that FDA is enforcing through Warning Letters without following formal rule-making procedures.

Compounded Thyroid Medication Options

Compounded Thyroid Medication Options

Written by Kathy Lynch, PharmD – Women’s International Pharmacy

 

People with low thyroid function often turn to compounders in their search for additive-free thyroid medications. Many are sensitive to the fillers and binders used in the manufacturing of compressed thyroid tablet formulations. Patients with autoimmune thyroid problems, for example, may respond better to corn-free thyroid preparations. Others with lactose intolerance will want thyroid medications that are lactose-free.

Women’s International Pharmacy has been compounding thyroid capsules in a variety of oils for years. We are able to compound liothyronine (T3) and levothyroxine (T4) as separate compounds, or in combination with each other. These bioidentical thyroid hormones are synthesized in the laboratory from a non-animal source. They contain T3, T4, or both, compounded with a small amount of oil (usually olive) and encapsulated in gelatin capsules, with vegetarian or dye-free options.

We also compound desiccated porcine thyroid capsules in much the same manner. Desiccated porcine thyroid powder (lactose-free) contains a fixed ratio of T3 to T4. Each powder lot comes with a certificate of analysis for the concentration of T3 and T4.

All compounded medications require a prescription from a licensed medical practitioner. If you are interested in compounded thyroid hormone capsules, feel free to call and speak with one of our many knowledgeable pharmacists.
