It is shown that cross-linked dextrans can be the basis for obtaining
a drug reservoir which is a physiologically active polymer with the dr
ug grafted to the matrix by chemical links. A drug form for treatment
of tuberculosis has been obtained. The kinetics of drug release into m
odel media and blood plasma has been investigated. It is found that po
lymeric derivatives of isonyazide and kanamycin can be applied for the
development of drug reservoirs with lower rate of release over a long
period of time.
