Abstract
In accordance with the present invention, there are provided stabilized total nutrient admixture (TNA) compositions which are useful for the in vivo parenteral delivery of pharmacologically acceptable lipids or fats, as well as methods for the preparation thereof. In particular, the pharmacologically acceptable lipid or fat is contained within a protein walled shell. In a particular embodiment of the invention, a TNA composition using human serum albumin (HSA) as a stabilizer has been prepared as a convenient three-in-one formulation (i.e., containing a fat emulsion, dextrose, and amino acids plus electrolytes). This “three-in-one” formulation can be prepared in liquid form or in dry form (comprising submicron-sized nanoparticles). The dried material is stable, even under long term storage, and is easily reconstituted immediately before use by simply adding sterile water (with or without vitamin supplementation) This serves to rehydrate the powder into a TNA suitable for injection. The long shelf life, ease of reconstitution, and single-component injectability of invention compositions provide significant cost savings, as such compositions can be reconstituted and admin…
