The formulation record and compounding record is an easy-to-miss area of compliance, but with numerous cases of patient harm related to compounding it is critical that pharmacies, for patient safety and for their own liability, get it right. Probably the most notable is that of the New England Compounding Center, but even more recently problems with levothyroxine compounded formulations have received public attention and scrutiny.
Are your compounding and formulation records compliant? Without further ado, here is your crash course:
We all know that formulation records are the 'recipe' to be followed when compounding. Everything you compound should have a formulation record, but perhaps more importantly that formulation record should be evidence-based. In the first paper I ever published in a peer-reviewed journal, I described my final-year student project to standardize formulation records at the health-system I was on rotation at.
Prior to implementation, the formulation records were on index cards in a form of a 'recipe box,' with handwritten notes, sometimes missing sources, and sometimes stating that the formulation record came from another hospital (pictures are in the paper). I would argue unfortunately this situation is not uncommon, and either developing or buying evidence-based formulation records is one of the easiest things any pharmacy, community or inpatient (or other), can do to improve the safety of compounded medications.
It also provides documentation in the case there is a lawsuit; after all, would you want to be on the stand as the lawyer grills you on why you made a medicine for a patient based on a word-of-mouth recipe? I certainly don't.
Formulation record components are regulated by USP 795, 797 (and remember - chapters below 1000 are considered mandatory!), and state Boards of Pharmacy.
Here are the components required:
• Name, strength, and dosage form of the CSP
• Physical description of the final preparation
• Identities and amounts of all ingredients and appropriate container-closure systems
• Complete instructions for preparing the CSP, including equipment, supplies, and a description of the compounding steps
• BUD and storage requirements
• Quality control procedures (e.g., pH, filter integrity, and visual inspection)
• Sterilization method, if applicable (e.g., filter, steam, or dry heat)
• Any other information needed to describe the operation and ensure its repeatability (e.g., adjusting pH and tonicity and temperature)
So now the million-dollar question: where can I find evidence-based formulation records?
Most people who work in compounding know that PCCA is the top-notch provider of compounding resources. They sell products, but to me their biggest value is in the over 9,500 formulation records in their database and the clinical education team to help compounders solve tough problems. If you are planning on really getting into compounding it is worth considering membership. When I rotated through a PCAB accredited compounding pharmacy as a student I saw the value it provided first-hand.

If you really only plan on compounding occasionally and feel that it is not the right choice to join PCCA, you should still get your Formulation Records together for what you do compound.
Also, as a word of caution, it is best not compound complex formulations unless you have the education and experience to do so. Compounding is a specialty and should be treated that way!
In addition, these two websites (also included in the Helpful Links) provide free recipes. The UNC website has recipes already formatted into a Formulation Record, while Secundum Artum provides the recipe with necessary stability data but unfortunately does not create a full Formulation Record. I'm currently working on this, so be on the lookout for downloadable formulation records in the future!
