摘要:
A powdery preparation for mucosal administration which comprises a polymeric medicine and a cationic polymer. The preparation is formed by adding a cationic polymer [especially an aminoalkyl methacrylate copolymer or poly(vinyl acetal diethylaminoacetate)] to a polymeric medicine, optionally further adding a thickening polymer, and powdering the mixture. Thus, the polymeric medicine can be effectively absorbed through a mucous membrane.

摘要:
A preparation in powder form for administration through mucosa, comprising a medicine of high molecular weight and a cationic polymer is disclosed. By adding a cationic polymer (in particular, a copolymer of aminoalkylmethacrylate or polyvinyl acetal diethylaminoacetate) or a cationic polymer plus a viscous polymer to a medicine of high molecular weight for producing a preparation in powder form, it is possible to achieve effective absorption of the medicine of high molecular weight through mucosa.
