  • Publication number: 20200206139
    Abstract: Pharmaceutical compositions for improving the solubility and dissolution of poorly soluble drugs which contain a therapeutic agent, a pharmaceutically acceptable polymer, and a spontaneously emulsifying component are described herein. These pharmaceutical compositions have been prepared by thermal processes to obtain a composition which shows improved properties including improved solubility of the therapeutic agent above the amount of therapeutic agent which should be soluble in either the spontaneously emulsifying component or the pharmaceutically acceptable polymer. Also provided herein are methods of preparing and use thereof.

  • Patent number: 10660850
    Abstract: The present invention includes compositions and methods for treating and delivering medicinal formulations using an inhaler. The composition includes a space filled flocculated suspension having one or more flocculated particles of one or more active agents and a hydrofluoroalkane propellant. A portion of the one or more flocculated particles is templated by the formation of hydrofluoroalkane droplets upon atomization and the templated floc compacts upon the evaporation of the hydrofluoroalkane propellant to form a porous particle for deep lung delivery.

  • Publication number: 20190145223
    Abstract: Disclosed herein are compositions and methods for reducing fluid loss in a well bore. This invention relates to methods for wellbore strengthening and increasing the integrity of the borehole of an oil or gas well. In particular, the invention relates to methods for artificially increasing the temperature of a subsurface formation in the wellbore to increase the apparent wellbore strength. The mechanism for accomplishing this revolves around increasing fracture propagation pressure by actively manipulating thermal wellbore stresses.
