  • Sustained-release preparation of poorly soluble drug
    Patent number: 10668158
    Abstract: The present invention relates to a pharmaceutical composition containing a poorly soluble drug, hyaluronic acid, and a fatty acid, and to a method for preparing the same. The pharmaceutical composition of the present application has excellent stability even for long-term storage and allows a sustained release of the drug, thereby preventing an overdose of the drug and improving the therapeutic efficiency at an effected area.
    Type: Grant

  • Preparation method for magnetic composite for treating and diagnosing cancer
    Patent number: 9889212
    Abstract: A preparation method for a magnetic composite for treating and diagnosing cancer. The method may include a step of pyrolyzing a precursor of a magnetic nanoparticle in the presence of a conjugated polymer. The preparation method for a magnetic composite can produce a magnetic composite economically and efficiently because a magnetic composite comprising a magnetic nanoparticle coated with a conjugated polymer can be prepared by a single process.
