  • Coating method
    Patent number: 11766649
    Abstract: A process for coating carrier particles with inhalable drug guest particles, the process including providing an apparatus including a processing vessel having solid walls defining a chamber for receiving the particles and adding the particles to the chamber. Next, the cylindrical processing vessel is rotated about an axis to impart a centrifugal force of between 10 and 2100 g on the particles. Further a process coats carrier particles with guest particles, wherein the carrier particles include a material or a drug and wherein the guest particles include a solubility/dissolution controlling agent.
    Type: Grant

  • Coating apparatus and method
    Patent number: 11148111
    Abstract: The present invention relates to an apparatus for coating carrier particles with guest particles. The apparatus comprises a cylindrical processing vessel rotatable about its axis and having solid walls defining a chamber for receiving the particles, and a hollow shaft extending within the chamber at least partly along the axis of the cylindrical processing vessel, the hollow shaft defining a gas flow path connected to a gas inlet. The hollow shaft comprises one or more axially-extending slots or one or more axially-extending rows of apertures allowing fluid communication between the gas flow path and the chamber.
