    摘要: Anhydrous formulations are formed of a diblock copolymer (X—Y) having a hydrophilic block X comprising residues of monomer x, and a hydrophobic block Y comprising residues of monomer y; an additive selected from a polymer and an organic solvent, where the solvent is water-miscible and biocompatible, and the polymer is hydrophobic or hydrophilic and comprises residues of monomers x and/or y, the polymer optionally having a molecular weight that is less than the molecular weight of the diblock copolymer; and a drug. Upon admixture with water, the anhydrous formulations form drug delivery vehicles, preferably in micellar form. The inclusion of polymer and/or organic solvent provides for the formation of micelles at an enhanced rate, and/or provides the formation of micelles having an enhanced ability to incorporate drug(s), and/or provides the formation of micelles having advantageous physical characteristics, e.g., advantageous viscosity and/or melting point.
