Custom Enteric Carriers

With the development of pharmaceutical technology and new excipients, enteric carrier has been developed gradually. Enteric-soluble solid dispersions are solid dispersions that are located in the intestines for drug release by enteric-soluble materials. Colistin enteric-soluble solid dispersion was prepared by a veterinary drug center using cellulose acetate phthalate (CAP) as carrier. In vitro dissolution test showed that the dissolution rate of the enteric solid dispersion was very low in gastric juice, but the release rate was accelerated in intestinal solution at pH 6.8. In vivo experiments showed that the bioavailability of the enteric-soluble solid dispersion was higher than that of the crystalline powder, and the effective plasma concentration was maintained for a longer time. Therefore, the solid dispersion made of enteric-soluble materials can not only improve the bioavailability of drugs, but also have sustained release. Its commonly used carrier for cellulose and polyacrylic resin.
