Nonwoven Membranes for Drug Delivery Systems |
| abstract |
The present invention defines nonwoven membranes for controlled and slow release of therapeutic or cosmetic active agents on areas of the body to be treated. The nonwoven membrane comprises a single type of biocompatible electrospun nanofibers and microparticles of at least one therapeutic or cosmetic active agent having low water solubility, entangled between the nanofibers. |
