Abstract:
The present invention relates to electrospun fibres containing: i) a first and a second hydrophilic fibre-forming polymer that is soluble in a hydrophilic solvent, ii) a bioadhesive substance that is slightly soluble in said hydrophilic solvent, iv) a drug substance, wherein the first hydrophilic polymer has a solubility in water at 37° C. that is at least 10 times greater than the solubility in water at 37° C. of the second hydrophilic fibre-forming polymer, and wherein the bioadhesive substance is present in solid form.

Claim (Index 37):
A method for preparing electrospun fibres, comprising:\n (i) dissolving first and second hydrophilic polymers in a solvent selected from ethanol and ethanol-water mixtures to obtain a solution, (ii) suspending a bioadhesive substance in the resulting solution from step (i) to obtain a dispersion, (iii) optionally, adding a drug substance to the resulting dispersion from step ii), and iv) electrospinning the resulting dispersion from step (ii) or mixture from step (iii), wherein said first and second hydrophilic polymers are soluble in said solvent, and said bioadhesive substance is at most slightly soluble in said solvent, to obtain electrospun fibres, wherein at least 90% w/w of the bioadhesive substance is present in solid form.
