摘要：
A pharmaceutically acceptable bio-adhesive coating, film or gel is formed in situ at a body surface by the reaction of (i) an anionic polymer or tripolyphosphate and (ii) a cationic polymer in the presence of water. The two components are supplied either as separate aqueous solutions or in a single non-aqueous formulation, which can be a liquid suspension tablet, capsule or powder.
