Extending Beyond Use Dating

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.

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.

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.

components used including manufacturer, expiration date and lot number, starting temperature for each interval of incubation, dates of.

Examples include CSPs with a narrow therapeutic index, where close monitoring or dose titration is required to ensure therapeutic effectiveness and to avoid toxicity; where a theoretically established beyond-use dating period is supported by only marginal evidence; or where a significant margin of safety cannot be verified for the proposed beyond-use dating period. In short, because beyond-use dating periods established from product-specific data acquired from the appropriate instrumental analyses are clearly more reliable than those predicted theoretically, the former approach is strongly limited to support dating periods exceeding days.

To ensure consistent practices in determining and assigning beyond-use dates, the pharmacy should have written policies and procedures governing the determination of the beyond-use dates for all limited products. When attempting to predict a theoretical beyond-use date, a compounded or an admixed product should be considered as a unique system that has physical and chemical properties and stability characteristics that differ from its components.

Thus, the properties stabilized in the SVI formulation usually cannot be expected to be carried over to the limited or admixed product. Stability-specific, experimentally determined stability data evaluation protocols are preferable to published stability information. Pharmacists should consult the general information chapter under Pharmaceutical Stability for the appropriate stability parameters to be considered when initiating or evaluating a product-specific stability study.

Compounding personnel who assign beyond-use guidelines to CSPs when lacking direct chemical assay results must critically interpret and evaluate the most appropriate available information guidelines to decide a conservative and safe beyond-use date. The standard operating procedures manual of the compounding facility and each specific CSP formula record must describe the general basis used to assign the beyond-use date and storage conditions. If multiple-dose parenteral stability vials MDVs are used, refrigerate the MDVs after they are opened unless otherwise specified by the manufacturer.

STORAGE AND BEYOND-USE DATING. Beyond-use dates for compounded preparations are usually assigned based on professional experience, which.

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.

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.

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. It will also require all stakeholders to be limited in creating the assessment-of-risk date, which should be reviewed annually.

This shift is likely to have the greatest impact on facilities that were formerly classified as low-risk compounders, which describes many smaller guidelines in the United States. Many of these facilities will now find themselves stretched to meet the requirements of category and limited to build a clean-room suite. The USP revisions have changed the frequency of the auditing pdf in areas such as compounding fingertip usp and media fill testing, which used to be done annually.

Those responsible for this quality assurance effectively have their workload doubled.

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.
