  • Patent number: 11000481
    Abstract: The present invention relates to a composite preparation with various dosage forms comprising mosapride and rabeprazole. The composite preparation prepared according to the present invention allows rapid release of a drug without deteriorating its release by an interaction between mosapride and rabeprazole, thus exhibiting an improved drug release rate and bioavailability, while having excellent product stability and being capable of significantly lowering the amount of the excipient. Accordingly, the composite preparation of the present invention can improve patients' drug compliance due to the size of its dosage form.

  • Patent number: 9962390
    Abstract: The formulation for oral administration of the present invention containing Mosapride or its salt is a double layer formulation consisting of a fast-release layer for rapid release of a drug and a sustained-release layer for slow release in order to simultaneously satisfy the rapid exhibition of pharmacological activities and sustained maintenance of pharmacological activities for 24 hours, wherein the high-viscosity hydroxypropyl methylcellulose (HPMC) and the low-viscosity HPMC are used in mixture such that the content of a high viscosity HPMC as a controlled-release matrix within the sustained-release layer has a higher content, thereby capable of controlling the dissolution rate in the regions having different pH values within the gastrointestinal tract and/or the retention time in the gastrointestinal tract.

  • Publication number: 20110318275
    Abstract: The present invention relates to a biocompatible contrast agent and a method of its preparation. More particularly, the present invention relates to a multifunctional contrast agent manufactured by prepairing a novel polysuccinimide-based polymer by introducing an alkanolamine group to the main group of the polysuccinimide in addition to a biocompatible hydrophilic group, which improves bioavailability, and a hydrophobic group, which enables to maintain the form of stable nanoparticles during the formation of nano particles for a long period of time and to encapsulate a hydrophobic anticancer agent.

  • Publication number: 20100303922
    Abstract: Disclosed are biocompatible polymeric nanoparticles for drug delivery and a method for preparing the same. They can be prepared by mixing a tri-block copolymer, PEG, and a drug at a predetermined temperature to give a homogeneous polymeric mixture; solidifying the homogeneous polymeric mixture at room temperature; and dissolving the solidified polymeric mixture in an aqueous solution. Based on a polymer melting process, the method makes it easy to produce poloxamer nanoparticles at low cost. The nanoparticles show desired particle sizes suitable for use in drug delivery and a uniform particle size distribution. Consisting of a bilayer structure, the nanoparticles can contain sparingly soluble drugs. Also, the nanoparticles contain no organic solvents and are thus safe to the body because they are free of organic solvent residuals.
