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.

Guidelines for the Establishment of Appropriate Beyond Use Dating of Sterile Compounded Admixtures

Instead, the proposed chapter would follow a new system for assigning BUDs based on several different factors related to achieving and maintaining sterility. Read the Notice on the USP website for detailed information. Eagle provides analytical and microbiological testing services , as well as consulting to help you ensure compliance with compounding standards and regulations. Eagle consultants are helping compounding facilities implement successful quality systems.

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.

Predictions based on literature are considered theoretical beyond-use dates as the published data introduces varying degrees of assumptions with a likelihood of error or inaccuracy. State and federal regulations also require pharmacists to have written justification for a beyond use date assignment. The only truly valid beyond use date is obtained through product-specific studies supported by scientific data.

These direct testing studies use stability indicating methods SIM to ensure therapeutic effectiveness of compounded drug products. A SIM is a reliable, meaningful, and specific analytical procedure that accurately and precisely measures active pharmaceutical ingredients API by separating the API from its degradation products and excipients. A SIM must be validated for the exact formulation being tested.

High performance liquid chromatograph HPLC is one of the most commonly used techniques for examining the chemical stability of compounded product, but not all HPLC tests are stability indicating. A forced degradation study must be performed on the compounded drug product and not inferred from testing on only the API. Testing the concentration of the drug is just one component of a stability study.

Extending Beyond Use Dating

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.

Beyond-Use Dating. Records and compounded, use-by date, and name, strength, and quantity of active ingredients. An exception to Nonsterile Preparations, and Chapter , Pharmaceutical Compounding—Sterile Prepara- tions, when.

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.

The pre-administration storage duration and temperature limits specified apply in the absence of direct sterility testing results that justify different limits for specific CSPs.

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?

Establishing Beyond-Use Dates) if made in accordance with all of the applicable requirements for Category 2 CSPs in this chapter.

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

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.

BUDs are defined by USP Chapter as the date or time after which a compounded sterile preparation (CSP) shall not be administered.

Considerations include the microbiological risk level, storage temperature, chemical stability, batch size, and whether or not a sterility test will be performed. The United States Pharmacopeia Chapter provides guidance on the maximum beyond-use date allowed solely based on the microbiological risk level associated with the compounding of a sterile preparation. Compounders should select the shortest beyond-use date between the risk-level based beyond-use date and the chemical stability of the compound.

When compounding pharmacists intend to provide a compounded sterile preparation with a beyond-use date that exceeds the risk-level based recommendations in United States Pharmacopeia Chapter , they must ensure that their formulations are sterility tested in compliance with United States Pharmacopeia Chapter. United States Pharmacopeia Chapter compliance includes conducting method suitability that is applicable to the strength and batch size that they plan to prepare.

Chemical stability must be a separate consideration for each formulation. Printer-Friendly Version. Bot Detector.

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.

PPE is put on after personal outer garments, all mouthwash, and jewelry and revisions are removed. Depending on the environment, PPE can include dedicated shoes or shoe covers, head and facial hair covers, face masks, and eye guidelines, after which the personnel must cleanse their guidelines and don a gown.
