摘要 |
A pharmaceutical composition comprising a biologically active agent preserved in particulate form, in particular a glass or amorphous particle, such as a sugar, a metal carboxylate, an amino acid or calcium phosphate, wherein said particles are suspended in at least one of a hydrofluoroether, a perfluoroether, a hydrofluoroamine, a perfluoroamine, a hydrofluorothioether, a perfluorothioether, a hydrofluoropolyether or a perfluoropolyether. The use of such fluorinated liquid media overcomes the problem of aggregation of particles and also is environmentally friendly. |
