The osmolality of total parenteral nutrition (TPN) solutions is a critical factor that determines the safest route of administration, as peripheral infusions are typically limited to an osmolality of less than 900 mOsm/L. A precise calculation is therefore essential for mitigating risks such as thrombophlebitis and ensuring optimal patient outcomes.

According to the American Society for Parenteral and Enteral Nutrition (ASPEN), pharmacist intervention in Total Parenteral Nutrition (TPN) can significantly improve patient outcomes and reduce medication errors. This is because what is total parenteral nutrition in pharmacy involves the highly technical process of creating a complex, life-sustaining nutrient solution delivered intravenously when the digestive system is not functioning.
