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.
Three concepts that create a lot of confusion: stability, beyond-use date, expiration
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.

USP 797 Guidelines & Standards
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.
Some state boards of pharmacy permit pharmacy to compound for another date under central stability regulations. USP chapter has since been revised.
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.

Guidelines for the Establishment of Appropriate Beyond Use Dating of Sterile Compounded Admixtures
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 If the manufacturer cannot assist in assigning a beyond use date, the next step is to obtain published stability information from reference books or the primary literature. Direct extrapolation of the information to the specific compounded formulation requires that the scientific study data utilize the same drug source, the same drug pdf, and the same compounding procedures, stores the formulation in the same container, and has subjected the formulation to the same anticipated environmental variables.
A growing number of compounding sources contain stability information, and the pharmacist should have ready access to this material.
USP was subsequently introduced in , with an implementation date of December The purpose of this chapter is to describe.
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. Finally, while these guidelines are generally applicable to all personnel who prepare CSPs and all guidelines in which CSPs are prepared, pharmacists and other health care professionals responsible for the preparation, selection, and use of CSPs are urged to use professional judgment in interpreting and applying these guidelines to their specific circumstances.
Users of these guidelines are cautioned that the information provided is current as of publication and are urged to consult current stability of original sources e. Significant legal and regulatory changes have taken place since publication of the previous ASHP guidelines Figure Some states have specific regulations dealing with Pdf for date use. Some pharmacies whose primary purpose is preparing CSPs for hospitals and other guidelines may be registered with the FDA as manufacturers and must adhere to federal good manufacturing practices.
Some state boards of pharmacy permit pharmacy to compound for another date under central stability regulations. USP chapter has since been revised. In addition, organizations preparing hazardous drugs , should comply with National Institute for Occupational Safety and Health NIOSH recommendations to ensure that compounding personnel are operating in a safe environment.

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. Nonsterile preparations typically include oral suspensions, topical solutions, topical suspensions, topical gels, powders, ointments, creams, emulsions, and suppositories.
The U. For the convenience of those studying this program, the numerous acronyms used are compiled in Table 1. Sterile compounding evolved primarily in hospitals in the s and s. It involves preparations that are made in sterile environments aseptically by mixing, diluting, repackaging, or manipulating injectable products. The injections and infusions compounded in hospitals and other health systems include large-volume parenterals LVPs and small-volume parenterals SVPs.
Beginning with pharmacist-prepared, centralized IV admixtures in the s, hospitals have provided aseptic environments within which to compound sterile products and prevent microbial contamination, including the use of laminar airflow hoods and rooms with high-efficiency particulate air HEPA filters and work practices to support aseptic compounding.
