| 20080226564 | Respiratory dispersion for metered dose inhalers - A respiratory dispersion is provided for the pulmonary delivery of at least two bioactive agents. The dispersion comprises a propellant suspension medium having dispersed therein a plurality of perforated microstructures, wherein the two bioactive agents are incorporated into individual perforated microstructures. | 09-18-2008 |
| 20080233194 | Dispersion for pulmonary delivery of a bioactive agent - Stabilized dispersions are provided for the delivery of a bioactive agent. The dispersions preferably comprise a plurality of perforated microstructures dispersed in a suspension medium that typically comprises a liquid fluorochemical. As density variations between the suspended particles and suspension medium are minimized and attractive forces between microstructures are attenuated, the disclosed dispersions are particularly resistant to degradation, such as by settling or flocculation. In particularly preferred embodiments the stabilized dispersions may be directly administered to the lung of a patient using an endotracheal tube or bronchoscope. | 09-25-2008 |
| 20100272823 | PULMONARY DELIVERY PARTICLES COMPRISING WATER INSOLUBLE OR CRYSTALLINE ACTIVE AGENTS - A pulmonary delivery medicament comprises a plurality of particulates, the particulates comprising a structural matrix and a water insoluble and/or crystalline active agent. The particulates have a geometric diameter of 0.5 to 50 μm. The water insoluble active agent can be a fungicide, antibiotic, budesonide. A method of making the medicament comprises forming a liquid feedstock, and forming a feedstock suspension by suspending in the liquid feedstock, the active agent and an excipient capable of forming a structural matrix, such as a phospholipid. The feedstock suspension is spray dried to produce the particulates. | 10-28-2010 |
| 20100329984 | RESPIRATORY DISPERSION FOR METERED DOSE INHALERS - A respiratory dispersion for pulmonary delivery comprises one or more bioactive agents, a suspension medium, and a plurality of perforated microstructures having a mean aerodynamic diameter of less than 5 μm. The suspension medium comprises at least one propellant and permeates the perforated microstructures. | 12-30-2010 |
