ABSORBABLE MICROPARTICLES |
摘要 |
This invention pertains to a sustained release complex of one or more peptides, one or more proteins or a combination thereof immobilized on an absorbable polymer microparticle optionally having an absorbable polymer coating. The microparticle complex of this invention comprises a peptide(s) and/or protein(s) which have at least one amino group and/or at least one carboxyl group per molecule and a solid absorbable polyester microparticle having surface and subsurface carboxylic group or amino groups in sufficient amounts to bind the peptide(s) and/or protein(s) so that the immobilized peptide(s) or protein(s) represent 0.1 % to 30 % of the total mass of the microparticle complex. The microparticle complex with immobilized peptide(s) and/or protein(s) are optionally further encased individually or in groups with an absorbable polymer to control, further, the release of the immobilized peptide(s) and/or protein(s). To control the release of the immobilized peptide(s) and/or protein(s) even further, the encased microparticles can be incorporated into a composition with an absorbable gel-forming liquid that transforms to a flexible gel or semi-solid upon contacting water in the biologic environment. |
