How long can High Risk CSPs be stored at room temperature before reaching their BUD?

High-risk compounded sterile preparations (CSPs) have specific guidelines regarding their BUD (beyond-use date), especially when stored at room temperature. According to the United States Pharmacopeia (USP) guidelines, high-risk CSPs are considered to be those that contain non-sterile ingredients or are prepared using non-sterile equipment and/or in a non-sterile environment. When determining the storage time for these preparations at room temperature, it is crucial to adhere to the standards set forth for safety and efficacy.

The appropriate BUD for high-risk CSPs when stored at room temperature is generally 24 hours. This time frame is established to minimize the risk of contamination and ensure that the stability and sterility of the preparation are maintained. After this point, the risk of microbial growth and degradation of the product increases significantly, which can compromise patient safety.

Understanding these guidelines is vital for pharmacists as it directly relates to the management of sterility and the safe dispensing of compounded medications. Hence, recognizing the importance of adhering to the 24-hour storage limit for high-risk CSPs at room temperature helps ensure compliance with regulatory standards and promotes patient safety.
