Muco-adhesive polymers |
摘要 |
Compositions comprising cationic polysaccharide polymers and anionic therapeutic agents which can have enhanced substantivity to mucosal surfaces are disclosed. These compositions are well suited, for example, for the delivery of anionic ophthalmic pharmaceuticals because they can provide clear solution in addition to substantivity.
