ABSTRACT:
An improved bioactive agent delivery composition and method of application are described. The composition comprises a bioactive agent, a hydrophilic polymer in an incompletely hydrated state and a substantially water-miscible solvent system. The agent and polymer are essentially dissolved in the solvent system to form a sprayable composition having a viscosity of less than 350 cP. Upon dilution with water, the viscosity of the composition increases to in excess of 1,000 cP to produce a retentive coating at the site of application which provides enhanced bioavailability of the agent.
