Biologically active compositions, and methods for their preparation, comprising a carrier matrix supersaturated with active agent

摘要

A biologically active composition comprising a biologically active agent to be released therefrom. The biologically active agent is dissolved and/or dispersed in a carrier, wherein the carrier is a liquid and/or solid non-crystalline matrix in which the biologically active agent is present in a supersaturated state. This supersaturated state is obtainable by subjecting one or more carrier starting substance to such chemical operation(s) that the liquid and/or solid non-crystalline carrier matrix is provided in which the degree of saturation of the biologically active agent is higher than in the carrier starting substance, the biologically active agent being added before the chemical operation(s) has(have) been completed.
