  • Manufacture of particles for pulmonary drug delivery by carbon dioxide assisted nebulization
    Publication number: 20060105051
    Abstract: Methods of making porous particles by using carbon dioxide assisted nebulization (CAN) technology in combination with spray drying technologies are disclosed. As the mixture of carbon dioxide (CO2) and the solvent with drug matrix is expanded through the nebulizer to atmospheric conditions, the resulting aerosol contains fine micro-bubbles and/or micro-droplets that contains dissolved CO2 which is co-currently fed into a spray drying chamber.
