Fine grain carriers and medicinal composition prepared with the use of the same |
| abstract |
The present invention is directed to particulate carriers useful as drug carriers in a drug delivery system (DDS) and to pharmaceutical compositions making use of such carriers. The invention is characterized by the use, as the particulate carrier, of: graft copolymer (A) whose graft chain is poly N-alkylacrylamide chain, poly N-alkylmethacrylamide chain, etc.; and a composition containing a combination of the graft copolymer (A) and at least one graft copolymers selected from the group consisting of graft copolymers (B-1) having polyacrylic acid or polymethacrylic acid as the graft chain and graft copolymers (B-2) having a polyvinyl amine compound as the graft chain. |
