Abstracted from the Editorial Appearing in the July/August Issue of IJPC
The Two NASEM Reports on Compounded Topical Pain Creams and Bioidentical Hormone Therapy
Here are a few comments on two different sections common to both reports, namely the
- lack of safety and efficacy documentation, and
- need for additional pharmacy education.
Safety and Efficacy Documentation
It is correct that more data is desired and that it would be advantageous to have complete data for each patient and each compounded preparation. However, such a situation is unrealistic or would even be unachievable for quite some time. Regarding the lack of safety and efficacy documentation which involves short- and long-term clinical studies for each "formulation" that is prescribed and compounded, along with numerous others studies involving formulation effectiveness, etc., these studies would be nice, but are costly, take time, and the physician has prescribed the specific formulation for the patient at this time (now).
Also, studies must be done on essentially the "same" product whereas compounded products vary depending upon the needs of the patient, and a single drug product may have up to 50 variations, which makes it impossible to do under the current requirements for valid clinical studies.
The current choice is to either compound the preparation for the patient as prescribed as long as it is reasonable and appropriate, or let the patient do without the medication with subsequent consequences. Marketed FDA-approved drug products today are only available in limited dosage forms (formulations) and one primary reason for compounding is to compound the drug in a formulation that is suitable for the specific patient.
In fact, the Report recognizes that compounding is tailored to meet the specific clinical needs of an individual patient; including children, the elderly, the hospitalized, those in long-term care, for ambulatory patients, and others. There are thousands of different formulations compounded each and every day to meet the needs of hundreds of thousands of patients. This explains why there is limited clinical data on a specific formulation, as the cost to obtain such data on even one formulation is extremely high, and there is no sponsor to obtain the information for thousands of compounded preparations for individual patients. Compounded preparations are prescribed for an individual patient for immediate use, and it is not practical to wait 2 to 10 years for clinical data to be produced on one specific formulation/product.
Pharmacy Education
Pain Report - Recommendation 3: To state boards of pharmacy, schools of pharmacy, and nonprofit professional societies and organizations within the medical and pharmaceutical sectors:
Require continued training for clinicians who prescribe compounded pain medication, particularly pain management specialists. Revise current educational requirements for compounding pharmacists and non-pharmacists who compound.
The Report is correct in recognizing that education on pharmaceutical compounding needs to be revised and increased. In the 1970s and 1980s, the science and technology related to drug products and laboratory experiences was decreased to make room for more "clinically-oriented" courses.
The Millis Report (1976) projected that pharmacists in the future would have less to do with the drug product and be more involved with a knowledge system, the product of which is a service; there will be many roles a pharmacist can perform. After almost 50 years, the purely clinical role has not been realized and, instead, the majority of pharmacists are still intimately involved in dispensing and counseling about the manufactured drug products and compounding nonsterile and sterile drugs in neighborhood pharmacies, hospitals, and specialty pharmacies.
The Millis Report says of clinical pharmacy1:
...one must cite the growing interest and involvement in what is generally called clinical pharmacy. I have not found a definition to which all will agree. However, it is clear that it refers to a pharmacy practice centered on the drug-related needs of patients.
This Editor has often said that compounding pharmacists are clinical pharmacists, as they are intimately involved with the "drug-related needs of patients" and must work hand-in-hand with the physician and the patient to optimize the patient's drug therapy.
A competent compounding pharmacist must also be thoroughly trained in pharmaceutics/physical pharmacy, drug product formulation, clinical pharmaceutics, pharmaceutical chemistry, compounding pharmacy, as well as in clinical and administrative pharmacy.
Regarding the "curriculum," the Millis Report says:
A second recommendation concerning the curriculum is that it should be structured to produce competencies identified and defined as appropriate for the practices of pharmacy.
Note that the word is "practices," plural, as there are many different "practices" of pharmacy of which compounding is significant and vital, but there is insufficient training on it in the colleges.
The NASEM cBHT report even states that currently there are 26 to 33 million prescriptions for compounded hormone formulations alone with their costs upwards of $2 billion annually, and compounding is expected to continue growing. Keep in mind that cBHT accounts for only a portion of compounded medications, as there are many nonsterile as well as sterile products, including intravenous admixtures, compounded daily.
Summary
The concerns related to safety and efficacy evaluation and expectations involving them are questionable, as it is not feasible to require complete clinical studies for each and every compounded formulation. The educational curriculum for pharmacy does need to be addressed and more classes/laboratories provided in compounding and content related to compounding, both nonsterile and sterile.
