Abstract:
The neomycin-furazolidone-xanthan complex has been synthesized. Neomycin is covalently linked to xanthan, while furazolidone is inserted in the hydrogel formed by the reaction between neomycin and xanthan. The content of neomycin and furazolidone depends on the drug rate in the reaction medium. Thus, a zero-order kinetics is obtained for the release of both neomycin and furazolidone in basic medium. The complex's antimicrobial activity is intensified.
