A Summary of Proposed Changes to USP 797

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.

General notices and closures. Name according to usp underwent new revisions as of july At mcguff compounding. An updated draft of providing.

In sterile health care organizations, patients receive compounded sterile preparations CSPs that are stored for extended periods before use. It has long been recognized that extended storage of Date may allow for the growth of a pathological bioburden of microorganisms and that patient pdf and mortality can result from contaminated or incorrectly compounded sterile preparations. These guidelines are intended to help compounding personnel prepare CSPs of high quality and reduce the potential for harm to patients and consequences for compounding personnel.

The recommendations in these guidelines are based on published data, when available; on expert opinion and procedures used in similar industries; and on applicable regulations and standards. Many health care settings also use CSPs prepared by compounding pharmacies. Although these guidelines may be useful in assessing the quality of CSPs prepared by compounding pharmacies, more information on the topic of outsourcing sterile compounding services is available in the ASHP Guidelines on Outsourcing Sterile Compounding Services.

Due to pending appeals, the effective date of USP remains postponed until further notice and USP remains “informational” until is finalized.

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.

Update on USP Chapter

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. Expiration dates are associated with commercially available products, while beyond-use dates are assigned to pharmacy compounded preparations.

Otherwise, the usp should ensure that the manufacturer’s stability information is product specific, that is, the exact strength, diluent, fill volume, and container type PVC bag, plastic syringe, elastomeric infusion device, etc. Pharmacists should obtain a letter from the sterility certifying the beyond use dating period provided. Step

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.

USP’s bylaws provide that the official date of a standard under appeal must be postponed while an appeal is pending. Therefore, USP postponed.

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. Beyond use dating applies the same expiration dating principles, but adds the consideration of sterility. Each category differs in the potential for microbial contamination during the compounding of the admixture.
