Some considerations on the study of nutritional fat emulsions
Nutritional fat emulsions are usually oil-in-water emulsions prepared by emulsifying oils extracted from ani-mals and plants as the oil phase,phospholipids as emulsifiers,supplemented with isotonic agents and water for injection.As an ideal energy supply substance for parenteral nutrition,nutritional fat emulsions can provide essential fatty acids and main-tain cell structure and functions.Thus,quality control of nutritional fat emulsions requires further improvements considering the complex composition of their APIs and high requirements for production process.In order to provide guidance for future research and development,this article addresses some research considerations based on the characteristics of nutritional fat emulsions,drug evaluation experience,and current domestic and foreign regulatory requirements.
