Abstract:

Nanocapsule-based Eudragit RS100 and Eudragit E100 containing indomethacin have been prepared. The nanosuspensions have been included into pectin microgels of different polysaccharide concentrations, 28-61 μm-ranged polymer microgels with size and size
polydispersity highly depending on the pectin amount being thus obtained. Study of the drug release revealed that indomethacin was released at a slower and more controlled rate from the microgels containing nanocapsules than from the empty pectin microgels. Also, the rate of released indomethacin increased with the augmentation of pectin amount into the microgels.
