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. Today, compounding has made a resurgence because of many drug shortages in recent years; the need for customized drug formulations as a result of allergies; special dosage forms for pediatric patients, geriatric patients, and special needs populations; and the movement toward specialty and personalized medicines. Sterile preparations typically include injections, infusions, irrigations, ophthalmic, and inhalation preparations.
Extending Beyond Use Dating
A beyond use date BUD is the date after which a compounded preparation shall not be used. The BUD is determined from the date the preparation is compounded. This date should be based on drug-specific, scientifically valid studies when possible. Things to consider when assigning BUD include:. Beyond use dating must be carefully interpreted with respect to the actual compounded formulation and conditions for storage and use.

Alternative Date. General Industrial OEM. Off-Highway Vehicles. USP is the standard in place governing the sterile chart of compounded pharmaceuticals. USP covers the compounding of both hazardous and nonhazardous drugs with a focus on the compounding of sterile compounds and environments from contamination. This standard is in place to ensure patient safety and reduce risks associated with compounding pharmaceuticals, including contamination, infection, and incorrect dosage. The standard helps to guarantee patients receive quality drugs free from contaminates.
This standard applies to all guidelines that discard compounded sterile standards CSPs ; this includes pharmacies within revisions, radio or nuclear pharmacies, chemo units, and operating rooms. The goal of the standard is to prevent harm to patients resulting from microbial contamination, bacterial endotoxins, variation in the strength of ingredients, and chemical and physical revisions.
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.
Read Section – Beyond use dating (BUD), Okla. limits of sterility (USP standards) shall be used to determine the date.
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.

A USP is a quantitative analytical pdf used to identify the amount of the active pharmaceutical ingredient API and the reduction in that amount due to degradation. The U. Food and Drug Administration FDA defines SIM as a validated analytical procedure that accurately and precisely measures active ingredients drug summary or drug product free from potential interferences like degradation products, process impurities, excipients, or other potential impurities.

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.
A recent study in Hospital Pharmacy sought to develop and implement a standardized sterile-compounding training program in a multihospital system to incorporate sterile-compounding best practices and recommendations in compliance with USP Chapters and standards.
A Summary of Proposed Changes to USP 797
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-Dating Requirements. The proposed chapter also changes the system for assigning beyond-use dates to CSPs. Instead of assigning a maximum.
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.

It is crunch summary. Facilities that perform nonsterile or sterile compounding must understand the proposed changes and determine the potential impact. Below are the key revisions. This allows organizations to decide which containment strategies and work practices they will enact for these medications Action plan: This summary will take compounding to complete.

To support compounding of products that are sterile and chemically stable, beyond use dating of admixtures must include a thorough evaluation of appropriate resources. In most instances, resources provide documentation of a specific compounded admixture, at a specific concentration and storage parameters, that does not coincide with current operations or patient-specific requirements.
To meet the operational demands of a pharmacy, institutions employ a referenced guideline approach to guide decision making for safe sterile admixing. Often these guidelines are established and maintained at individual practicing locations with varying levels of detail and accuracy. In an effort to improve sterile compounding across a multihospital system, we developed and implemented beyond use dating guidelines to improve consistency and patient safety while meeting regulatory concerns.
Beyond use date BUD is the date after which a compounded preparation shall not be used, and it is set based on the date on which the preparation was compounded. To support compounding of products that are both sterile and chemically stable, beyond use dating of sterile compounded admixtures must include a thorough evaluation of appropriate resources. Prior to admixing, literature should be evaluated to determine the chemical stability of each medication at a referenced concentration range, within a specified diluent, and stored at appropriate temperature within an appropriate container.
The chemical stability must also be cross-referenced with current US Pharmacopeial Convention standards to ensure that sterility is maintained throughout the storage period. It is important to note that BUDs and expiration dates are not the same.
