797 beyond use dating chart
The resulting relatively short default storage time limits for CSPs provide a high probability of sterility assurance without sterility testing evidence.
Storage in a refrigerator or freezer has shown to slow the growth of microorganisms allowing for longer BUDs for CSPs stored under colder temperatures versus controlled room temperature. In the expiration dating of laboratory reagents of passing a sterility test, high risk compounded sterile products cannot be stored for more than 24 hours at controlled room temperature, more than three days in cold temperatures or for more than 45 days if frozen solid and held at degrees Fahrenheit or less.
Those characteristics include method of achieving sterility, if sterility testing is performed, and if a preservative is added.
Yes, a strength potency over time test determines the amount of active ingredient in a preparation, however, it may not be able to separate the active ingredient from its degradation products and impurities for quantitation depending on the analytical methods used for the test. Either of those may occur particularly with multi-day therapy as in the following examples. When administration is initiated within the 30 or hour BUD, the CSP may be infused until the end of the 5-day therapy, because that falls within the day chemical stability timeframe.
In addition, assuming rather than verifying directly or by examining the labeling dating sites with photos documentation that the chemical purity and strength of bulk ingredients meet their specifications establishes a high-risk condition.

The USP Compounding Compendium contains the 5 essential compounding chapters, beyond use dating chart 40 supporting general chapters, and more than compounded preparation monographs. A beyond-use date BUD is the date or time after which administration of a CSP shall not be use and is determined from the date or time the preparation is compounded 1.
Medical grade refrigerators and freezers provide a uniform environment, as well as help stabilize and maintain temperatures during and after door openings allowing the correct BUDs to be assigned. Storage Conditions and BUD.
Sterile Compounding Similar Posts. Thorough preparation combined with enhanced storage conditions refrigeration and freezing can dramatically increase the time that the CSP can be stored before administration.
In the this 5-FU example, beyond 30 hours if medium risk or 48 hours if low risk of completing compounding, either the administration of the 5-FU CSP to the patient must begin or the CSP must be discarded.
Risk levels are assigned based on guidance from the chapter as well as expertise of the professional and can always be more conservative not more lenient than what is stipulated in the dating chart.
Exposing sterile ingredients and devices to air quality below ISO Class 5 will create a high-risk compounding situation, as will the prolonged storage of opened or partially-used products that lack antimicrobial preservatives in an environment in les than ISO Class 5 conditions.
The processing and packaging of ingredients as well as environmental storage and transport conditions are the main factors affecting chemical and physical stability.
USP Chapter sets compounding risk levels based on the likelihood of contaminating a compounded sterile preparation CSP with microorganisms, spores, endotoxins or other foreign material. Therefore, particular CSPs may be:.
Without performing a sterility test, CSPs should not be stored longer than 48 hours at a controlled room temperature, 14 days in refrigerated settings or 45 days if frozen solid at degrees Fahrenheit or colder. A stability-indicating method will be able to quantitate the active ingredient and its degradation products or related impurities in the preparation by separating the active 797 from its degradation products and impurities, and to show a change in the concentration of the active ingredient with increasing storage time.
Share or write a comment! Qualifying a Testing Lab. Without passing a sterility test, medium-risk CSPs may be stored for 30 hours at room temperatures of 25 to 40 degrees Fahrenheit, 9 days at cold temperatures and 45 days if frozen solid and held at degrees or less.
Based on the current version of the chapter, a 5-FU infusion made from not greater than 3 ingredients drug, diluent if one was used and final container is a low risk CSP.
