Moisture containing compositions that are spreadable onto and adherable to biomembranes

Abstract

This invention relates to compositions that are easily spreadable onto and adhesive to biomembranes. They contain and provide moisture to the biomembranes and do not readily flow off, i.e., leak from the biomembranes. Nor are they readily removed or washed from the biomembranes. Compositions that adhere to and are compatible with, in that they spread, and do not flow off and are not readily removed or washed from the biomembranes are deemed to be bioadhesive. Such compositions are particularly useful for maintaining biomembranes in a moist condition, for lubricating the biomembranes, and for providing a vehicle for containing and delivering medicaments, such as contraceptives, antifungals and antibacterials. The invention further relates to methods for making and methods of use of such compositions. The compositions of this invention are particularly useful for maintaining biomembranes in a moist condition, especially those that are susceptible to dryness, for lubricating the biomembranes and for providing a vehicle for containing and delivering medicaments, such as contraceptives, antifungals and antibacterials.
