  • Process for Producing Polymer Micelles Encapsulating Low Molecular Weight Drugs
    Publication number: 20090074874
    Abstract: The present invention provides a method of encapsulating a low molecular weight drug in a polymer micelle, the method comprising the steps of: (a) dissolving or dispersing the drug having an electric charge in an aqueous medium; (b) preparing an aqueous medium containing a polymer micelle comprising a block copolymer having an overall hydrophobic region and a hydrophilic region, the overall hydrophobic region containing hydrophobic side chains and side chains having an electric charge opposite to that of the low molecular weight drug in random order; (c) mixing the aqueous medium having the low molecular weight drug dissolved or dispersed therein and the aqueous medium containing the polymer micelle; and (d) adjusting the pH of the mixed aqueous medium to a pH at which the encapsulation of the low molecular weight drug is stabilized.
