  • Patent number: 8927006
    Abstract: Methods for treating and preventing otitis externa with a course of treatment consisting of as little as a single dose are provided. The methods are practiced by topical administration of compositions having a lipid carrier, such as liposomes and non-vesicular lipids, to the outer ear canal. Such compositions lack viscocity-enhancing celluloses or adhesives, and are preferably not in the form of a gel. Active agents useful for treating pain, inflammation, fungal or parasitic infestation and/or infections in the outer ear are co-administered in or with the composition.

  • Publication number: 20080124385
    Abstract: Methods for treating and preventing middle ear infections by transmembrane administration of medicament-containing transmembrane carrier compositions, such as liposomes and other lipid vesicles, to the tympanic membrane. Medicaments useful for treating pain, inflammation or infection in the outer ear may be co-administered. If utilized for transmembrane administration, the liposomes or other lipid vesicles will usually not be sterically stabilized. The medicaments delivered according to the methods of the invention include antibiotic, anti-viral, anti-fungal and anti-inflammatory agents that are useful in treatment and/or prophylaxis of middle ear infections and their sequelae.

  • Patent number: 7263516
    Abstract: The invention provides a method, system, and computer program product for storing and elaborating user preferences for objects in response to a user's name. The invention associates a user's name with an entitlement expression that includes a reference to at least one membership map having preference information regarding the preference objects and associates with the preference objects a unique identifier that acts as an index into each membership map. The entitlement expression is evaluated for the user's name to determine a list of preferred objects for that user. The evaluation includes looking up the preference object's membership information in at least one membership map of preference using the preference object's unique identifier. The invention may further include at least one preferred group having a name, zero or more objects that are members of the preferred group, and a membership map for determining whether a particular object is a member of the group.

  • Patent number: 6780885
    Abstract: The present invention provides non-aqueous compositions which comprise a pharmacologically or biologically active compound, an emulsifier, a polyol, and benzyl alcohol. The compositions are useful for administering the pharmacologically or biologically active compounds which they contain to animals, plants, or ground surfaces. In preferred embodiments, the pharmacologically or biologically active compounds may be water-insoluble or water-labile. The compositions of the present invention allow these compounds to be solubilized and conveniently transported to a site of application in a non-aqueous form, and then diluted in an aqueous solution. In a particularly preferred embodiment, the compound is ivermectin and is administered in the drinking water of poultry. The compositions of the present invention may also contain multiple pharmacologically or biologically active compounds which are administered simultaneously. The present invention also provides methods of administering the compounds.

  • Patent number: 6423338
    Abstract: The present invention relates to pharmaceutical compositions for the sustained release of pharmacologically active compounds, and methods of their manufacture and use. The pharmaceutical compositions contain microcrystals of pharmacologically active compounds which are encapsulated within a phospholipid layer which contain a unique combination of phospholipids. The pharmaceutical compositions may be rendered suitable for injection. The microcrystals are of varying sizes. At least 50 percent of the microcrystals are from 0.5 &mgr;m and 3.0 &mgr;m in diameter, at least ten percent of the microcrystals are from 3.0 &mgr;m to 10 &mgr;m in diameter, and the composition may contain microcrystals which are greater than 10 &mgr;m in diameter. Methods of manufacturing the composition are disclosed, as well as various methods of administration.
