Compounding TPN admixtures: then and now.

Area of Science:

• Pharmaceutical Sciences
• Clinical Nutrition
• Healthcare Management

Background:

• Parenteral nutrition (PN) compounding has evolved significantly over 35 years.
• Pharmacy departments are now primarily responsible for compounding safe PN admixtures.
• The United States Pharmacopeia (USP) Chapter 797 establishes standards for sterile compounding.

Purpose of the Study:

• To highlight the critical role of pharmacists in ensuring the safety of parenteral nutrition (PN) admixtures.
• To discuss the physicochemical and aseptic technique challenges in PN compounding.
• To emphasize the need for continuous improvement in PN protocols due to ongoing safety issues.

Main Methods:

• Review of historical developments in PN compounding.
• Analysis of regulatory standards (USP Chapter 797) and their implications.
• Discussion of stability, compatibility, and sterility issues in TPN admixtures.
• Examination of the role of professional organizations (e.g., ASPEN) in guideline development.

Main Results:

• Pharmacists are uniquely qualified to manage the complexities of PN compounding.
• Adherence to USP Chapter 797 is crucial for safe sterile preparations.
• Instances where patient needs cannot be met by TPN admixtures due to safety concerns necessitate alternative delivery methods.

Conclusions:

• The pharmacist's expertise is essential for safe and effective parenteral nutrition therapy.
• Ongoing vigilance and adaptation of PN protocols are necessary to address persistent safety challenges.
• Collaboration and adherence to evolving guidelines are key to optimizing TPN safety.
