Question: Since a cannabidiol (CBD) commercial product has been U.S. Food and Drug Administration (FDA) approved, can I compound with any CBD oil or product?
Answer: There is only one source of cannabidiol that can be used in compounding—Epidiolex.
A summary of Section 503A of the Federal Food, Drug and Cosmetic Act describes compounding as being allowed using drug substances that:
- comply with standards of an applicable USP [United States Pharmacopeia] or NF [National Formulary] monograph, if a monograph exists, and the USP chapter on pharmacy compounding;
- if such a monograph does not exist, are drug substances that are components of FDA-approved drugs; or
- appear on a list developed by the FDA that:
- are manufactured by an establishment that is registered and
- that are accompanied by valid certificates of analysis for each bulk drug substance and does not appear on a list of drug products that have been withdrawn or removed from the market due to safety or effectiveness reasons and does not compound regularly or in inordinate amounts copies of any commercially available drug products.
There is only one source of CBD that fits the above requirements for compounding and that is Epidiolex (cannabidiol 100-mg/mL oral solution). Each bottle contains 100 mL of a clear, colorless to yellow solution.
Cannabidiol, the active ingredient in Epidiolex and only one of more than 80 active chemicals in marijuana, occurs as a white to pale-yellow crystalline solid that is insoluble in water and is soluble in organic solvents.
It is a strawberry-flavored, clear, colorless to yellow solution; each mL contains 100 mg of cannabidiol. Epidiolex also contains dehydrated alcohol, sesame seed oil, strawberry flavor, and sucralose.
There is a brief listing of the nervous system disorders related to Epidiolex in the "DID YOU KNOW?" section of this Newsletter.
