Matrix drag delivery systems

MicrocrystalUne cellulose (MCC) is mainly used in the pharmaceutical industry as a diluent/binder in tablets for both granulation and direct compression processes. Treating high quality cellulose with hydrochloric acid to the desired level yields purified miCTocrystalline cellulose which is a partially depolymerized cellulose [21]. Membrane controlled systans or monolithic matrix drag delivery systems obtained from cellulose derivatives provide controlled release of drags. Film coating techniques are employed for the manufacture of membrane controlled... [Pg.37]

Pharmaceutically, guar gum is widely used as a colon-specific drug carrier in the form of matrix and compression-coated tablets as well as microspheies. Table 1 summarizes type of dosage form, drag, chemical composition, and drug release profiles of some delivery systems made of guar giun. [Pg.427]
