SELF-ADHESIVE HYDRATABLE MATRIX FOR TOPICAL THERAPEUTIC USE

摘要

A self-adhesive, biocompatible and hydratable polymeric matrix has the form of a sheet, patch or film. The matrix is suitable for application to moist surfaces both inside and on the external surface of the body. The matrix comprises a naturally occurring or synthetic polymerisable and/or cross- linkable material that supports wound healing, and a synthetic polymer havin g bioadhesive properties. The bioadhesive properties enable the matrix to adhe re to underlying tissue by means of ionic and/or hydrogen bonding.
