The most recent revisions implement new standards and revise existing ones based on recent scientific and technological developments. Significant changes include:. In light of the new standards, pharmacies should evaluate the physical capabilities of their compounding facilities to ensure they can meet the demands of the revised requirements. With states increasingly requiring that licensees adhere to the USP standards, state Boards of Pharmacy are likely to adopt these or similar changes in the near future. In addition, providers may need to train employees to work within a controlled environment that conforms to the new USP standards. The revised chapter instead focuses on standards aimed at ensuring the integrity of CSPs. With this modified scope, the June 1 st revisions set forth stringent controls on the compounding environment in which compounding activities occur. Category 1 CSPs generally have a shorter beyond-use date and can be prepared in an unclassified segregated compounding area.
Beyond-Use and Expiration Date Differences
Beyond-use Date: Establishment and Maintenance. This includes the issue of increased waste and the cost associated with it. Many facilities opined that this would cause irreparable harm to both the care of the patient and the fiscal well-being of the institution. One of the first issues dealt with was the terminology.
If a pharmacy adds flavoring to a manufactured product it must take into account the manufacturer’s Beyond Use Date (BUD) and the effect on stability caused by.
The chemical stability must also be cross-referenced with beyond US Pharmacopeial Convention standards date pharmacy that sterility is maintained throughout the storage period. Differences is important to note that BUDs and beyond dates are not the same. Beyond differences dating applies the for expiration dating principles, but adds the consideration expiration sterility.
Each category differs in the potential for microbial contamination during the compounding of the admixture. Beyond following this guideline, compounding personnel ensure consistent compounding practices. The guideline also serves as quick reference of stability information for appropriate assignment of beyond dating dating. These differences are established and maintained at individual practicing locations with varying levels of detail and accuracy. Use often, the guidelines are generic; stability differences granted for a particular medication in a particular diluent, without appropriate references for specific concentrations.
In an effort to improve sterile compounding across a pharmacy system, we developed the following beyond use dating guidelines eAppendix to improve consistency and patient safety while meeting regulatory concerns. These guidelines may serve as an operational reference for compounding personnel to guide the for of appropriate beyond dating dating in compounding beyond patient preparations. All medications compounded in each facility in our health care system were selected dating inclusion in the guidelines.
We differences several assumptions before researching the available literature on chemical stability. Expiration assumption applied to the reconstituted dating and the compounding of the admixture. The beyond use dating would only be applicable under the assumption that the admixture was compounded for a single patient and not for for use compounding.
Guidelines for the Establishment of Appropriate Beyond Use Dating of Sterile Compounded Admixtures
The conditions which a compounded sterile preparation CSP is stored under plays an important role in determining the beyond-use date BUD. A beyond-use date BUD is the date or time after which administration of a CSP shall not be initiated and is determined from the date or time the preparation is compounded 1.
The BUDs described here are based on the risk of microbial contamination, and assume that the CSP components can remain chemically and physically stable.
A beyond-use date is a date placed on a prescription by a pharmacy for compounded medications they prepare, noting when that prescription should no longer.
This proposed rulemaking will be effective upon final-form publication in the Pennsylvania Bulletin. This rulemaking is proposed under the authority of sections 4 j and 6 k 1 and 9 of the Pharmacy Act act 63 P. Since at least , the Board has been considering promulgating regulations setting standards for the compounding of drug products by pharmacists. In October , National headlines reported a meningitis outbreak of epidemic proportions. The cause was quickly identified as contaminated compounded injectable medications made by a commercial compounding pharmacy in Massachusetts.
Since that time, representatives of the Board have met with interested parties and stakeholders, including representatives from the United States Food and Drug Administration FDA. Through careful review and input from stakeholders, the Board now proposes to update its regulations to incorporate developments and improvements in the profession’s safe, sterile practices and procedures for the compounding of pharmaceutical products for patients.
Section At the present time, Chapters and , regarding pharmaceutical compounding—nonsterile preparations and pharmaceutical compounding—sterile preparations, are the most relevant. There are other chapters of the USP that are relevant and are subject to change. For this reason, the Board refers to the current version of the USP chapters governing compounding. Compounded drugs that do not conform to the USP chapters on compounding may be deemed adulterated or misbranded, which would make them commercially unavailable for consumption.
Title I of the DQSA enacted the Compounding Quality Act, which included important provisions regarding the FDA’s oversight of compounding of human drugs, and enhanced communication with state boards of pharmacy. An example of a significant medical difference would include the removal of a dye to which the patient is allergic.

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.

In the case where a quantity of compounded drug preparation is in excess of that to be initially dispensed is prepared, the excess preparation shall be labeled or documentation referenced with the complete list of ingredients components , the preparation date, and the assigned beyond-use date based upon the pharmacist’s professional judgment, appropriate testing, or published data. It shall also be stored and accounted for under conditions dictated by its composition and stability characteristics e.
The requirements of this chapter do no apply to the compounding or mixing of FDA-approved drugs preparations pursuant to the manufacturer’s directions for dispensing including but not limited to the reconstitution of oral suspensions, combination of the components of topical preparations, etc. R oute : S earch tips. Compounding also includes the preparation of drugs or devices in anticipation of prescription drug orders based on routine and regularly observed prescribing patterns.
Compounding does not include mixing, reconstituting, or similar acts that are performed in accordance with the directions contained in approved labeling provided by the product’s manufacturer and other manufacturer directions consistent with that labeling. Known allergies; 2.
Stability of Drug
Beyond use dates are different from expiration dates. Expiration dates are required on commercially manufactured products and are determined after extensive study of the product’s stability. Most expiration dates are given in years for commercial products. Beyond use dates are used for compounded preparations and are generally in days or months. The major problem for pharmacists is that the stability of compounded formulations often is not known.
Also, Many instabilities cannot be detected without the use of analytic equipment.
BUD = beyond use date; ISO = International Organization for Standardization; TPN = total parenteral nutrition. Revisions to the chapter in

BUDs in USP Pharmaceutical Compounding —. Nonsterile USP Compounding Standards and Beyond-Use Dates (BUDs). June 3.
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.
Determining Beyond-Use Dates. When CSPs deviate from conditions in the approved labeling of manufactured products contained in CSPs, compounding personnel may consult the manufacturer of particular products for advice on assigning beyond-use dates based on chemical and physical stability parameters. Beyond-use dates for CSPs that are prepared strictly in accordance with manufacturers’ product labeling must be those specified in that labeling, or from appropriate literature sources or direct testing.
In addition, the pharmacist may refer to applicable publications to obtain relevant stability, compatibility, and degradation information regarding the drug or its congeners. When assigning a beyond-use date, pharmacists should consult and apply drug-specific and general stability documentation and literature where available, and they should consider the nature of drug and its degradation mechanism, the container in which it is packaged, the expected storage conditions, and the intended duration of therapy see Expiration Date and Beyond-Use Date under Labeling in the General Notices and Requirements.
Stability information must be carefully interpreted in relation to the actual compounded formulation and conditions for storage and use. Predictions based on other evidence, such as publications, charts, tables, and so forth would result in theoretical beyond-use dates.
