摘要
Mucoadhesivity of cationic derivatives of cellulose is an important factor, when testing their suitability for controlled drug delivery systems. For this purpose, the interaction of hydroxyethylcellulose (HEC), as well as tertiary amino derivative of HEC, with lyophilized mucin was investigated by means of turbidimetric titration, microscopy and measurement of zeta potential and particle size changes in the system. The cationic derivative exhibited distinct mucoadhesive properties, while the interaction of HEC with mucin was much weaker. A possible mechanism of the interaction is discussed.
