  • Publication number: 20100226997
    Abstract: An ophthalmically acceptable vehicle includes an aqueous suspension having a first viscosity. The suspension includes about 0.1% to about 6.5% by weight of a carboxyl-containing polymer prepared by polymerizing one or more carboxyl-containing monoethylenically unsaturated monomers and less than about 5% by weight of a cross-linking agent. The polymer has average particle size of not more than about 50 ?m in equivalent spherical diameter. The vehicle includes a second polymer that allows the carboxyl-containing polymer to remain suspended. Upon contact with tear fluid, the vehicle gels to a second viscosity which is greater than the first viscosity. A method of administering a medicament to the eye of a subject includes applying a composition that includes this ophthalmically acceptable vehicle and a medicament contained for treatment of a disease or disorder for which ophthalmic delivery is indicated. The medicament is released from the vehicle in a sustained release manner.

  • Patent number: 7625548
    Abstract: Liquid nanoscale particle precursor materials for generating nanoscale particles include at least one high volatility carrier and a second component. A nanoscale particle generating device generates nanoscale particles by passing a liquid nanoscale particle precursor material through a flow passage heated to convert the carrier into a vapor and the second component into nanoscale particles. The nanoscale particles preferably consist essentially of the second component and can consist essentially of dry, solid particles. The particle generator can be incorporated in a hand held inhaler, and can be delivered to a targeted portion of the lung using the inhaler. Composite controlled release particles of micron or nanoscale size can be produced by flowing a solution of medicament, control release agent and carrier liquid through a capillary heater.

  • Publication number: 20040223918
    Abstract: Liquid aerosol formulations for generating cromolyn sodium aerosols include at least one high volatility carrier and an optional additive such as a surfactant and/or low volatility liquid. In some embodiments, the liquid aerosol formulation is propellant free. An aerosol generating device generates an aerosol by passing liquid aerosol formulation through a flow passage heated to convert at least some of the liquid into a vapor, which is mixed with air to form an aerosol. In some embodiments, particles of the aerosol consist essentially of the cromolyn sodium or cromolyn sodium in combination with an additive such as a surfactant and/or low volatility liquid. The aerosol generator can be incorporated in a hand held inhaler and the aerosol can be delivered to a targeted portion of the lung using the inhaler for treatment of asthma.
