  • Method of preparing drug agglomerate
    Patent number: 9833436
    Abstract: A method of preparing drug agglomerates includes adding a drug powder to a first solvent to form a first solution, adding a second solvent to the first solution to form a second solution. The drug powder undergoes nucleation to form drug agglomerates. The drug agglomerates are isolated from the second solution.
    Type: Grant
    Filed: April 28, 2017
    Date of Patent: December 5, 2017
    Assignee: PharmaDax Inc.
    Inventors: Pei-Chun Kuo, Shih-Wei Huang, Chiung-Fang Chang

  • Method for controlling lag time of in-situ passageway formation in osmotic delivery system
    Publication number: 20070014858
    Abstract: An osmotically controlled delivery system includes a solid core having a shallow indentation on a surface of the core, and a semipermeable membrane enclosing the solid core. The solid core is made by a drug composition being caopable of generating an osmotically effective pressure, and the semipermeable membrane is relatively thinner at the shallow indentation. An in-situ exit passageway is formed in the indentation position when external aqueous fluids are imbibed through the semipermeable membrane into the dosage form by an osmotic pressure gradient. A process for forming an in-situ exit passageway of an osmotic delivery dosage form, a controlled onset dosage form, and a method for controlling the lag time of in-situ passageway formation are also disclosed.
