Examples include CSPs with a narrow therapeutic index, where close monitoring or dose titration is required to ensure therapeutic effectiveness and to avoid toxicity; where a theoretically established beyond-use dating period is supported by only marginal evidence; or where a significant margin of safety cannot be verified for the proposed beyond-use dating period. In short, because beyond-use dating periods established from product-specific data acquired from the appropriate instrumental analyses are clearly more reliable than those predicted theoretically, the former approach is strongly limited to support dating periods exceeding days. To ensure consistent practices in determining and assigning beyond-use dates, the pharmacy should have written policies and procedures governing the determination of the beyond-use dates for all limited products. When attempting to predict a theoretical beyond-use date, a compounded or an admixed product should be considered as a unique system that has physical and chemical properties and stability characteristics that differ from its components. Thus, the properties stabilized in the SVI formulation usually cannot be expected to be carried over to the limited or admixed product. Stability-specific, experimentally determined stability data evaluation protocols are preferable to published stability information. Pharmacists should consult the general information chapter under Pharmaceutical Stability for the appropriate stability parameters to be considered when initiating or evaluating a product-specific stability study. Compounding personnel who assign beyond-use guidelines to CSPs when lacking direct chemical assay results must critically interpret and evaluate the most appropriate available information guidelines to decide a conservative and safe beyond-use date. The standard operating procedures manual of the compounding facility and each specific CSP formula record must describe the general basis used to assign the beyond-use date and storage conditions. If multiple-dose parenteral stability vials MDVs are used, refrigerate the MDVs after they are opened unless otherwise specified by the manufacturer.

Featured Issue Featured Supplements. Subscribe Jobs. The USP Chapter was introduced in to provide regulation to pharmacies on quality standards for compounding sterile products CSPs. USP was subsequently introduced in , with an implementation date of December The purpose of this chapter is to describe practice and quality standards for handling hazardous drugs.
Both USP and have the intent to promote safety and prevent patient harm by warranting sterility and accuracy of all CSPs. Failure to comply with these recommendations and standards may result in the greatest risk of contamination, leading to potential patient harm. With the focus on sterile-compounding training in these USP chapters, sterile-compounding facilities are required to develop and implement training processes in order to ensure safe and adequate training of compounding personnel.

The proposed chapter was open to public comments until November 30, , and is expected to become official on December 1, The proposed revision differs from the current chapter in both its structure and its content. Some of the changes are significant and will require major adjustments in pharmacy systems and processes, while other changes will be easier to accommodate. Here is a summary of some of the changes. The current chapter classifies compounded sterile preparations CSPs as low-, medium-, or high-risk level CSPs based on the sterility of the starting components and the number and types of compounding manipulations.
The proposed chapter, however, eliminates this system of classifications and instead classifies sterile preparations as either a category 1 or category 2 CSP based on the conditions under which the product was prepared. The proposed chapter also changes the system for assigning beyond-use dates to CSPs. Instead of assigning a maximum allowable BUD based on the risk level of the preparation, the proposed chapter follows a new system for assigning BUDs based on several different factors related to achieving and maintaining sterility.

The system that most pharmacies use to assign a date beyond which it should no longer be used seems to be a point of confusion. We, myself included, historically have given day beyond use dating to our products without a second thought and no real scientific data to back up that claim. Seems the revised BUD guidance gives some credence to preservatives, sterilization methods, etc, but with a maximum BUD of 45 days.

Beyond Use Date (BUD) is very different from expiration date. USP Chapter defines BUD as the date or time after which a compounded sterile preparation.
RAA is managed by Somnia. Q: As a practicing consultant pharmacist to ambulatory surgery centers, I am often asked about the beyond use dating of medications drawn into syringes. Since most ASCs do not have an isolator or glove box for this procedure, I advocate following USP , and consider those pre-drawn syringes an immediate-use compounded sterile preparation, and suggest a one-hour beyond use dating.
Is this too stringent? Does USP apply in these situations if they are not IV admixtures but are, for example, injectable local anesthetics which are not given intravenously? Clifford Gevirtz: Yes, I think you the consulting pharmacist are going a bit far in your interpretation. To quote from the USP guideline www. However, if the expiration date of the vial is sooner than 28 days, then it expires on that date. Good practice is note the date first entered on the label. Propofol Injectable Emulsion should be drawn into sterile syringes immediately after vials are opened.

The chapter was to have become official on December 1, , but USP-NF announced on September 23, , that appeals were pending on provisions of the chapter regarding beyond-use dating, use of alternative technologies proven equivalent to those described in the chapter, and applicability of the chapter to veterinary practitioners.
This notice and content of this program will be updated as events occur. Compounding has been a fundamental aspect of providing medicines to patients for centuries. Physicians, chemists, and pharmacists manipulated naturally derived products including those of plant, mineral, and animal origin into medicines. They did this through mixing, grinding, filtering, percolating, heating, and distilling, which led to preparations of vinegars, extracts, infusions, elixirs, syrups, tinctures, ointments, and pills.
STORAGE AND BEYOND-USE DATING. Beyond-use dates for compounded preparations are usually assigned based on professional experience, which.
Beyond-use dates for CSPs are rarely based on preparation-specific chemical assay results, which are used with the Arrhenius equation to determine expiration dates see General Notices and Requirements for manufactured products. The majority of CSPs are aqueous solutions in which hydrolysis of dissolved ingredients is the most common chemical degradation reaction.
The extent of hydrolysis and other heat-catalyzed degradation reactions at any particular time point in the life of a CSP represents the thermodynamic sum of exposure temperatures and durations. Such lifetime stability exposure is represented in the mean kinetic temperature calculation see Pharmaceutical Calculations in Prescription Compounding Drug hydrolysis rates increase exponentially with arithmetic temperature increase; thus, exposure of a beta-lactam antibiotic solution for one day at controlled room temperature see General Notices and Requirements will have an equivalent effect on the extent of hydrolysis of approximately 3 to 5 days in cold temperatures see General Notices and Requirements.
Personnel who prepare, dispense, and administer CSPs must store them strictly in accordance with the conditions stated on the label of ingredient products and finished CSPs. When CSPs are known to have been exposed to temperatures warmer than the warmest labeled limit, but not exceeding 40 see General Notices and Requirements for more than 4 hours, such CSPs should be discarded, unless appropriate documentation or direct assay data confirms their continued stability.
