Patent number: 8021582Abstract: A continuous phase liquid and a dispersed phase liquid are permitted to flow together through a co-flow channel. Preferably, the dispersed phase liquid is arranged to flow within the flowing body of the continuous phase liquid in the co-flow channel so that the dispersed phase liquid is sheathed by the continuous phase liquid. The continuous phase and dispersed phase liquids are comminuted into microparticles in the co-flow channel by intermittently blocking the co-flow channel.Type: GrantFiled: August 26, 2009Date of Patent: September 20, 2011Assignee: National Cheng Kung UniversityInventors: Gwo-Bin Lee, Cheng-Tso Chen

Publication number: 20110212169Abstract: Disclosed are a method for preparing a powder containing a nanoparticulated sparingly soluble drug, a powder prepared thereby, and a pharmaceutical composition containing the same. The disclosed method includes: providing a uniformly dispersed solution of a sparingly soluble drug which is formed into nanoparticles in the presence of a surface stabilizer; mixing the uniformly dispersed solution with a water-soluble dispersant solution; and drying the mixed solution to obtain the powder. When the powder containing the nanoparticulated sparingly soluble drug obtained by the disclosed method is redispersed in an aqueous solution, the sparingly soluble drug retains a particle size in the nano scale while the solubility and the dissolution rate of the drug are increased, thereby providing enhanced bioavailability. Consequently, the present disclosure can be useful in the development of preparations of a sparingly soluble drug for oral or parenteral administration.Type: ApplicationFiled: November 10, 2009Publication date: September 1, 2011Applicant: Amorepacific CorporationInventors: Joon-Ho Bae, Hyeok Lee, Deok-Ki Hong, Jong-Hwi Lee

Publication number: 20110182994Abstract: Methods and systems for preparing nanoparticles. A source of a carrier fluid is connected to an inlet of a flow conduit, such as an intravenous solution administration tube with injection ports, such that the carrier fluid flows through the conduit. A substance (e.g., a drug solution or other substance solution) is introduced into the conduit at a first location causing substance nanoparticles to form within and continue to flow thought he conduit. A stabilizer is introduced into the conduit at a second location to cause a stabilizing effect on the nanoparticles. In some embodiments, the stabilizer may limit or deter agglomeration or growth of the nanoparticles, thereby limiting the size of the nanaparticles produced.Type: ApplicationFiled: July 27, 2009Publication date: July 28, 2011Applicants: S.K.
