  • Publication number: 20140323451
    Abstract: Described here are methods for the treatment of respiratory conditions using nebulized corticosteroids. The methods administer a dose of corticosteroid twice a day or more with nebulization times of 5 minutes or less. The faster nebulization times improve patient compliance. The methods also employ a lower corticosteroid dose while achieving therapeutic efficacy similar to commercially available formulations. This results in improved patient safety by reducing the systemic exposure of the corticosteroid.

  • Patent number: 8486043
    Abstract: Described here are unit dose containers, methods, and kits for treating asthma and other pulmonary conditions by nebulization. The unit doses of active agents are provided in a low volume formulation, which results in faster nebulization of the unit doses. The containers are also formed to minimize internal surface area so that effective re-dispersion of the active agents can be achieved while reducing adsorption to the walls of the containers.

  • Patent number: 6818227
    Abstract: A method for administering a radiosensitizer to a tumor site in a subject is described. The method includes preparing liposomes composed of a vesicle-forming lipid and a lipid-derivatized radiosensitizer. In one embodiment, the radiosensitizer is dipalmitoyl-5-iodo-2′-deoxyuridine. A method for preparing the liposome composition including the lipid-derivatized radiosensitizer is also disclosed.

  • Patent number: 6051251
    Abstract: A method for loading a therapeutic compound having a cis diol moiety into pre-formed liposomes is described. The method includes adding to a suspension of liposomes (i) the compound to be loaded into the liposomes and (ii) a boronic acid compound, thereby achieving accumulation of the compound within the liposomes.

  • Patent number: 5064655
    Abstract: A liposome gel composition and method of preparing the same. The composition is composed of charged liposomes, at a relatively low lipid concentration, in a low-conductivity medium. The composition preferably contains a zwitterionic compound at its isoelectric point. The liposomes can be designed for cosmetic use, transdermal drug delivery, or enhanced retention on mucosal tissues, such as for ophthalmic use.

  • Patent number: 5030442
    Abstract: An aqueous, noncrystalline minoxidil composition for topical use which has significantly improved flux of the drug through human cadaver skin. The composition contains minoxidil complexed with an amphipathic compound, oleic acid and with pharmaceutically acceptable excipients. The composition may be formulated in an aqueous vehicle, or dispersed in fluorochlorocarbon solvent for spray delivery from a self- propelled spray device.

  • Patent number: 4944948
    Abstract: A composition and method for treating a wound or surgical incision, by sustained-released delivery of epidermal growth factor (EGF). The composition includes a high-viscosity aqueous dispersion of negatively charged liposomes with liposome-entrapped EGF. The EGF/liposome composition is formed, in one embodiment of the invention, by suspending a lipid mixture typically containing equimolar amounts of neutral and negatively charged phopholipids and cholesterol in a low-conductivity aqueous medium containing EGF and a zwitterionic compound whose isoelectric point is between pH 5.5 and 8.5 to form a gel-like composition. One embodiment of the invention contains EGF entrapped by surface adsorption to the liposomes, for slow release from the composition.

  • Patent number: 4828837
    Abstract: An aqueous, noncrystalline minoxidil composition for topical use. The composition contains minoxidil complexed with an amphipathic compound having a pK less than about 5 and containing a single lipophilic chain moiety and a sulfate, sulfonate, phosphate and phosphonate polar moiety. The composition may be formulated in ointment form, in an aqueous vehicle, or dispersed in a fluorochlorocarbon solvent, for spray delivery from a self-propelled spray device.
