Literatures about study on pharmaceutical excipients of nasal preparations have been analyzed.Thirty-two literatures at home and abroad were sieved.This paper reviews basic physicochemical properties

functionality and security of common nasal excipients（absorption enhancer

bio-adhesion

preservative）.It was demonstrated that based on manufacture

package

quality

storage and application of domestic nasal excipients

researchers have recognized the closing relation between nasal excipients and nasal preparation.To push forward the development and clinic application of nasal preparation

and quality standard of pharmaceutical excipient

strengthen organic combination of production

study and research

promote new excipients

new technology and new drug deliver system is important.
