Abstract
This invention relates to A bioadhesive composition comprising two or more essentially excretable, essentially non-degradable polymer backbones, wherein the polymer backbones are crosslinked, said crosslink being degradable in a mammal, said cross-linked bioadhesive composition having an average bioadhesion factor showing bioadhesion equivalent to at least about 100 g s. The concept is to build a hydrogel that demonstrates bioadhesion to a mucosal surface that is crosslinked by a degradable linkage such as disulfide for use inside the body.
