| 摘要 |
The invention relates to a novel biologically active composition which comprises a biologically active agent to be released therefrom, said biologically active agent being dissolved and/or dispersed in a supersaturated state within a carrier, which carrier is a liquid and/or solid non-crystalline matrix, and where the precipitation of said biologically active agent is substantially, or completely, inhibited therein. Said supersaturated state is obtainable by subjecting one or more carrier starting substance(s) to such chemical operation(s) that a matrix is provided in which the degree of saturation of said biologically active agent is higher than the degree of saturation of said biologically active agent in said carrier starting substance(s), the biologically active agent being added either before said chemical operation(s) or after a predetermined point of time, after which the composition thus prepared is further subjected to said chemical operation(s). |
