What is the storage duration for medium level risk compounds at refrigerated temperatures?

1. 3 days

2. 9 days

3. 14 days

4. 45 days

The correct answer is: 9 days

The storage duration for medium level risk compounded sterile preparations, when stored at refrigerated temperatures, is established for a period of 9 days. This categorization originates from guidelines provided by organizations such as the United States Pharmacopeia (USP), which sets strict standards to ensure the safety and efficacy of compounded medications. Medium risk compounds involve more complex preparation processes than low risk compounds and thus have a different stability profile. The recommendation for a 9-day storage period under refrigeration reflects a careful balance between maintaining the integrity of the compounded product and minimizing the risk of microbial contamination. Storing these compounds beyond this timeframe could lead to instability and possible degradation, which could negatively impact therapeutic outcomes. This information is crucial for pharmacists and pharmacy technicians to prevent loss of efficacy in compounded sterile preparations and to ensure compliance with both legal and professional standards regarding pharmacy practice. Adhering to these guidelines helps ensure the safety of patients receiving these medications.
