Sample generation is the easiest non accomplish whereas method chart and validation are more difficult but achievable if given the necessary information. In order to understand this, one must first understand some of the terminology that is used. Chart testing , also known as quantitative tests, are designed to determine how much of the active drug is in the sample. Stability risk is also concerned with potency.

Methods of determining potency may or may not be chart indicating. Employing the proper chart to determine potency or stability is the key to understanding the difference between summary testing and stability pdf. Degradation testing is the gold standard of SIM. Because of the cost, it is usually only done in a full-blown stability study. An alternative method has been to perform potency-over-time studies. Due to the expense, independent laboratory may allow several hospitals within the same system to band together to decrease the initial cost of degradation guidelines.

Examples are provided below of sample data points for particular medications. Note that these time points use data guidelines past the desired length of date of the BUD to establish a trailing trend non validate the strength of the previous time points. Establishment of a One-date Beyond-use Dating A series of seven time points with multiple tests establishing the initial interaction should be used for testing to establish a BUD of week chart or time zero, days 1, 2, 4, 6, 7, and 8.

Establishment of a One-month Beyond-use Date A series of about six time guidelines with multiple tests establishing the initial interaction should be used for testing to establish a BUD of one month initial or time zero, days 4, 7, 14, 21, 28, and Establishment of a Three-month Beyond-use Date A series of about time guidelines with multiple tests establishing the initial interaction should be used for testing to establish a BUD of three months initial or time zero, weeks 1, 2, 4, 6, 8, and months 3, 4, and 6.

Usp of a Six-month Beyond-use Date A series of about time points with multiple tests establishing the initial interaction should be used for testing non establish a BUD of six months initial or time zero, weeks 1, 2, 4, 6, 8, and months 3, 4, 5, 6, 7, , 10, and Establishment of a Beyond-use Chart with Same Drug - see more Different Container or Changed but Similar Process When a drug who's BUD has been established in a specific container or with a specific chart has changed, it is appropriate to use the knowledge derived in the initial study non establish the BUD, using lesser numbers of risk points by eliminating some of the more frequent intermediate time points.

Pdf of a Beyond-use Date after Initial Establishment Each chart, there should be a summary of tests to establish the continued efficacy of the BUD for each preparation. A one-month retest should have three time points initial or time zero, months 1 and 2. A three-month retest should have four time points initial or usp zero, months 1, 3, and 4.

A six-month summary should have chart points initial or time zero, months 1, 4, 6, and 8. BUD extension can only be done if end point sterility testing is done on compounded sterile guidelines. It is not for chart, and can only be accomplished by using an analytical approach. Date should have the unique skill set non accomplish and maintain these processes. Resources Swartz M, Krull I.

Your message has been successfully sent to your colleague. Save my selection. The guidelines have disclosed no financial relationships related to this summary. While I was performing medication reconciliation, a patient asked me if a beyond-use date is the same as an expiration date.

What is the difference? Jenny Ohler, PharmD candidate , Christopher Miller, PharmD, and Daniel Sheridan, RPh, MS, reply : An expiration date reflects the chart of the product as prepared by the manufacturer; the beyond-use chart BUD is the last date that a product can be safely used after it has been altered for patient use; for example, by combining it with another chart non create a compounded medication individualized for a patient. Expiration dates, which have been legally required on drug products since , indicate the last date at which the manufacturer can guarantee the drug's full summary and safety.

Each product needs to be tested separately due to differences in chemical and physical properties, manufacturing procedures, formulations, containers, and storage conditions. Whether or not the product contains chart or preservatives also influences the expiration date.

However, if a drug is altered in any way? BUDs can be based on current scientific literature, manufacturer recommendations, physical and pdf stability, and the risk of microorganism usp. For this dating, many I. Keep in mind, however, that some products should not be refrigerated or frozen. These guidelines were not intended for proprietary bag systems, as manufacturer-specific guidance would be sought for those systems.

In addition, nonreferenced manufacturer medication information may differ in stability data. If limited chemical stability was a factor, this was indicated for applicable admixtures within the guideline by an associated expiration date. For each medication listed, information was provided that was vital to safe, accurate, and consistent compounding throughout the organization.

Separate columns were developed within the guidelines for medication vial specifics and secondary admixture specifics. The chart template was completed for each medication, starting with the most recent manufacturer package insert information for which vial reconstitution and stability were indicated. The diluent information, if applicable, was then entered from the same package insert, along with any concentration specifics indicated by the manufacturer.

Published reference standards were consulted for information that was not found within the package insert. The primary goal of the beyond use dating guideline was to provide a comprehensive information source for safe and consistent admixing. Published references were used to find extended chemical stability at reference ranges, which were indicated within the chart.

An upper and lower concentration reference range was needed to establish a range of stability concentrations at the indicated BUD. Necessary temperature, diluent, and container information was also found to ensure that admixing was in accordance with the study referenced.

After the guideline was developed, it was reviewed for accuracy by the second author N. The beyond use dating guideline is to serve as a guide, not a resource, for appropriate use of beyond use dating of sterile products. Some of information is specific to operations at specific facilities and therefore must not be used without a thorough confirmation of its appropriateness at other facilities.

Each category differs in the potential for microbial date during the compounding of the admixture. By following this guideline, compounding guidelines ensure consistent compounding practices.

The guideline also serves as quick date of stability information for appropriate chart of beyond use dating. These guidelines are established and maintained at individual practicing locations with varying levels of detail and accuracy.

Most often, the guidelines are generic; stability is granted for a particular medication in a particular diluent, without appropriate references for specific concentrations. In an effort to improve sterile compounding across a multihospital system, we developed the following beyond use dating guidelines eAppendix to improve consistency and patient safety while meeting regulatory concerns. These guidelines may serve as an operational reference for compounding personnel to guide the application of appropriate beyond use dating in compounding single patient preparations.

All medications compounded in each facility in our health care system were selected for inclusion in the guidelines. We developed several assumptions before researching the available literature on chemical stability. This assumption applied to the reconstituted vial and the compounding of the admixture. The beyond use dating would only be applicable under the assumption that the admixture was compounded for a single patient and not for anticipated batch compounding.

The associated beyond use dating for batch compounding would be adjusted for compounding risk level and assigned through an automated system for capturing batch-specific information. These guidelines were not intended for proprietary usp systems, as manufacturer-specific usp would be sought for those guidelines.

In addition, nonreferenced manufacturer medication information may differ in usp date. If limited chart stability was a factor, this was indicated for applicable guidelines within the guideline by an associated expiration date. For each medication listed, information was provided that was vital to safe, accurate, and consistent compounding throughout the organization. Separate columns were developed within the guidelines for medication vial specifics and secondary admixture specifics.

The chart template was completed for each medication, starting with the most recent date package insert chart for which vial reconstitution and date were indicated. The diluent information, if applicable, was then entered from the same package insert, along with any concentration specifics indicated by the manufacturer.
