INERT SUPPORT MADE OF A RETICULATED COPOLYMER, METHOD OF PREPARING IT, AND ITS USE IN MAKING SUSTAINED-RELEASE DRUGS |
| 摘要 |
Inert cross-linked copolymer able to absorb and then progressively release a pharmaceutically active substance, wherein it is constituted by a powder of a cross-linked copolymer comprising 30 to 80% by weight of monounsaturated alkyl acrylate and/or methacrylate; 5 to 68% by weight of acrylic and/or methacrylic acid; and 2 to 15% by weight of bifunctional or trifunctional acrylate and/or methacrylate polymerized in accordance with free radical polymerization mechanisms. |
