Final answer:
The BUD for a compounded drug cannot be longer than its stability and sterility. Factors like drug type, composition, storage conditions, and testing determine the BUD.
Step-by-step explanation:
The BUD (Beyond Use Date) for any compounded drug cannot be longer than the stability and sterility of the drug. The stability of a compounded drug refers to how long the drug remains effective and maintains its potency. Sterility refers to the absence of microorganisms in the drug.
Stability and sterility are determined through various factors such as the type of drug, its chemical composition, storage conditions, and testing. For example, a compounded drug that contains preservatives may have a longer BUD compared to a drug without preservatives.
The BUD is crucial to ensure patient safety and the efficacy of the medication. If a compounded drug is used past its BUD, there is a risk of degraded effectiveness or potential contamination, which can lead to adverse reactions or infections.
