  • Publication number: 20040105818
    Abstract: Described herein are diuretic condensation aerosols and methods of making and using them. Kits for delivering a condensation aerosol are also described. The diuretic aerosols typically comprise diuretic condensation aerosol particles that comprise a diuretic compound. In some variations the diuretic compound is selected from the group consisting of bumetanide, ethacrynic acid, furosemide, muzolimine, spironolactone, torsemide, triamterene, tripamide, BG 9928, and BG 9719. Methods of treating edema using the described aerosols are also provided. In general, the methods typically comprise the step of administering a therapeutically effective amount of diuretic condensation aerosol to a person with edema. The diuretic condensation aerosol may be administered in a single inhalation, or may be administered in more than one inhalation. Methods of forming a diuretic condensation aerosol are also described.

  • Publication number: 20040099269
    Abstract: The present invention provides novel condensation aerosols for the treatment of disease and/or intermittent or acute conditions. These condensation aerosols have little or no pyrolysis degradation products and are characterized by having an MMAD of between 1-3 microns. These aerosols are made by rapidly heating a substrate coated with a thin film of drug having a thickness of between 0.05 and 20 &mgr;m, while passing a gas over the film, to form particles of a desirable particle size for inhalation. Kits comprising a drug and a device for producing a condensation aerosol are also provided. The device contained in the kit typically, has an element for heating the drug which is coated as a film on the substrate and contains a therapeutically effective dose of a drug when the drug is administered in aerosol form, and an element allowing the vapor to cool to form an aerosol. Also disclosed, are methods for using these aerosols and kits.

  • Publication number: 20030131843
    Abstract: The present invention relates to the delivery of drugs through an inhalation route. Specifically, it relates to the formation of drug thermal vapors from a heated open-celled substrate for use in inhalation therapy. In a method aspect of the present invention, a method of delivering a drug to a mammal through an inhalation route is provided which comprises heating a composition to form a thermal vapor, which is inhaled by the mammal, wherein the composition comprises a drug, and wherein the composition is coated onto a substrate, and wherein the substrate has a high surface to volume ratio, high porosity, and a three-dimensional network of interconnected cells.

  • Patent number: 5622944
    Abstract: Compositions and methods are provided for enhanced transdermal electrotransport of 17-hydroxy sterol compounds, including testosterone. The parent sterols are modified at the 17-hydroxy position by covalent attachment of a charged chemical modifier. The chemical modifier provides the parent sterol with enhanced transport properties and is hydrolyzed under physiological conditions to release the active parent compound.The composition comprises a 17-hydroxy sterol/chemical modifier complex, more generally represented by the formula (sterol--O--)C(O)--R--N(R.sup.1)(R.sup.2)(R.sup.3).sup.+. The portion of the complex derived from the chemical modifier is indicated by "C(O)--R--N(R.sup.1)(R.sup.2)(R.sup.3).sup.+ ", where N(R.sup.1)(R.sup.2)(R.sup.3).sup.+ represents a quaternary ammonium group and R.sup.1, R.sup.2, and R.sup.3 are independently selected from the group consisting of lower alkyl, alkyl, aryl, arylalkyl, cycloalkyl, heteroalkyl, and heteroarylalkyl; or R.sup.1 and R.sup.
