Category 1 CSPs and Storage Requirements

Category 1 Controlled Substances (CSPs) are a group of medications that have a high potential for abuse and are subject to strict storage and handling regulations. When it comes to storing Category 1 CSPs, it's essential to follow the guidelines set by regulatory agencies to ensure the safety and integrity of the medication. In this article, we'll focus on the storage requirements for Category 1 CSPs when stored at controlled room temperature.

What is Controlled Room Temperature?

Controlled room temperature (CRT) is a specific temperature range that is used to store medications that are sensitive to temperature fluctuations. The temperature range for CRT is between 20°C to 25°C (68°F to 77°F), with a relative humidity of 20% to 60%. This temperature range is ideal for storing medications that are sensitive to temperature and humidity changes.

Storage Requirements for Category 1 CSPs

When it comes to storing Category 1 CSPs, the storage requirements are critical to ensure the safety and integrity of the medication. According to the US Pharmacopeia (USP), Category 1 CSPs must be stored in a manner that prevents exposure to light, moisture, and temperature fluctuations. When stored at CRT, Category 1 CSPs must be assigned a Beyond-Use Date (BUD) that is based on the manufacturer's expiration date or the date of compounding, whichever is earlier.

What BUD Must be Assigned to a Category 1 CSP if Stored at Controlled Room Temperature?

The Beyond-Use Date (BUD) is the date by which the medication must be used or discarded. When it comes to Category 1 CSPs stored at CRT, the BUD must be assigned based on the manufacturer's expiration date or the date of compounding, whichever is earlier. According to the USP, the BUD for Category 1 CSPs stored at CRT must be assigned as follows:

12 hours or less: If the Category 1 CSP is stored at CRT for 12 hours or less, the BUD must be assigned as the date of compounding plus 12 hours.
18 hours or less: If the Category 1 CSP is stored at CRT for 18 hours or less, the BUD must be assigned as the date of compounding plus 18 hours.
24 hours or less: If the Category 1 CSP is stored at CRT for 24 hours or less, the BUD must be assigned as the date of compounding plus 24 hours.
30 hours or less: If the Category 1 CSP is stored at CRT for 30 hours or less, the BUD must be assigned as the date of compounding plus 30 hours.

Conclusion

In conclusion, when it comes to storing Category 1 CSPs at controlled room temperature, it's essential to follow the guidelines set by regulatory agencies to ensure the safety and integrity of the medication. The Beyond-Use Date (BUD) must be assigned based on the manufacturer's expiration date or the date of compounding, whichever is earlier. By understanding the storage requirements for Category 1 CSPs, pharmacists and healthcare professionals can ensure that these medications are stored and handled safely and effectively.

A: The BUD for Category 1 CSPs stored at CRT must be assigned based on the manufacturer's expiration date or the date of compounding, whichever is earlier.

Q: What is the date of compounding?

A: The date of compounding is the date on which the medication was compounded.

Q: What is the manufacturer's expiration date?

A: The manufacturer's expiration date is the date on which the medication was manufactured and is expected to be effective.

Q: How long can Category 1 CSPs be stored at CRT before the BUD must be assigned?

A: Category 1 CSPs can be stored at CRT for up to 30 hours before the BUD must be assigned.

Q: What happens if the Category 1 CSP is stored at CRT for more than 30 hours?

A: If the Category 1 CSP is stored at CRT for more than 30 hours, the BUD must be assigned as the date of compounding plus 30 hours, and the medication must be used or discarded by that date.

Q: Can Category 1 CSPs be stored at CRT for longer than 30 hours if the manufacturer's expiration date is later?

A: No, Category 1 CSPs cannot be stored at CRT for longer than 30 hours, even if the manufacturer's expiration date is later.

Q: What is the importance of following the storage requirements for Category 1 CSPs?
