Enhanced drag factor

It has been shown that hydrogen bonding-mediated interpolymer complexes can be powerful drag reducers. The drag-reduction levels in such polymer systems increase dramatically by a factor of 2 to 6 when compared with their nonassociating polymeric precursors. Their shear stability is also shown to be significantly enhanced [1156]. 

Research-based pharmaceutical firms worldwide have become highly conscious of all factors that can affect time to market of their new products. Every day on the critical path toward regulatory approval is important, economically and competitively. Early development of a robust process, both for drug substance and for drag product, significantly enhances time to market of a new product [9,12,14,15],... 

Milk fat globule membrane (MFGM) emulsion was shown to enhance the absorption of epidermal growth factor (EGF) from the intestine, especially to intestinal lymph. The oral bioavailability of propanolol was shown to increase when administered in oleic acid and other lipid media. It is thought that the oleic acid forms an ion-pair with the drag and the entire complex is incorporated into chylomicrons. A further factor in the absorption enhancing effects may be that oleic acid per se stimulates chylomicron production.
