The road to publishing the revisions to USP General Chapters <795> and <797> has been a long one. Since their initial publication in June of 2019, USP has received several appeals on <795> and <797>. These appeals included potential harm to patients, unjustifiable burden on established businesses, and concerns regarding the proposed guidelines departing from scientific consensus.1 Though these reasons for appeal continue to be sources of concern, USP published revisions to <795> and <797> on November 1st, 2022, stating they are “to be official 01-Nov-2023”.2,3
What does this mean for my practice?
Until November 1st, 2023, the current version of General Chapter <795>, which was last revised in 2014, will remain in effect. Similarly, the current version of General Chapter <797>, which was last revised in 2008, will also remain in effect until November 2023. It should be noted that while USP does create guidance documents for industry, they are not themselves a regulatory body. That said, many state regulators adopt USP guidelines into their rules and regulations. Some states may even adopt some or all of these new USP guidelines before November 1, 2023. As such, we encourage you to contact or closely follow communications from regulators (i.e., newsletters) in the states in which you are licensed.
What are the changes to beyond use dating (BUD) practices with new USP <795>?2
There are many changes from previous USP <795> in the updated guidelines. One area of concern to many compounders is beyond use dating for non-sterile compounded products. Included below is a comparison of current and updated BUDs. Of note, the updated guidelines do not divide aqueous dosage forms based on route of administration, but rather based on preservative status. This is consistent with a new emphasis on water activity (aw) and microbial growth that we see in updated guidelines. Updated guidelines reference specific aw values for determination on whether a particular preparation is aqueous or nonaqueous (for more information, see our blog post on water activity, linked below). Updated guidelines will also have more stringent requirements for BUD extension, including the requirement for stability indicating analytical methods, container-closure specific testing, and anti-microbial effectiveness testing per USP <51>, among other considerations.
What does this mean for USP 800?4
USP’s official statement on USP General Chapter <800> is that “USP General Chapter <800> is informational and not compendially applicable unless otherwise specified by regulators and enforcement bodies. For information on the scope, intended applicability, and implementation context for USP General Chapter <800>, see: https://www.usp.org/usp-800-context-for-implementation-fs.pdf.” Information provided by USP suggests that USP <800> is intended to become applicable to compounding activities through reference in the updated USP <795> and <797> guidelines. Given this information, USP <800> would be considered official on the same date as USP <795> and <797> updated guidelines. Again, note that some state regulators may adopt all or portions of USP <800> before November 2023.
