Abstract:
Disclosed is a mucoadhesive pharmaceutical composition comprising a poly-ionic complex of chitosan and a polyacrylic acid polymer. As an oral formulation, the composition has the extended retention time in the gastrointestinal tract by its mucoadhesive and swelling properties, which is useful as sustained release formulations, retentive formulations of active ingredients with limited absorption regions, and active ingredients with pH dependent solubility.

Claim (Index 12):
A method for preparing a mucoadhesive pharmaceutical composition, comprising:\n (a) adjusting pH of an acidic aqueous solution of chitosan and an aqueous solution of polyacrylic acid, respectively, and mixing them, or adjusting pH of a mixture of an acidic aqueous solution of chitosan and an aqueous solution of polyacrylic acid, to obtain a poly-ionic complex; and (b) drying and milling the obtained poly-ionic complex of chitosan and polyacrylic acid to obtain micronized poly-ionic complex.
