  • Patent number: 6799576
    Abstract: A system is disclosed which makes it possible for a patient to be delivered gradually reduced amounts of nicotine over time thereby allowing the patient to be gradually weaned off of dependence on nicotine and quit smoking. The system is comprised of a means for aerosolizing a formulation and containers of formulation. The formulation is comprised of nicotine in a pharmaceutically acceptable carrier. Preferably, a plurality of containers are produced wherein the concentration of nicotine in the different containers or different groups of containers is reduced. The patient uses containers with the highest concentration initially and gradually moves towards using containers with lower and lower concentrations of nicotine until the patient's dependence on nicotine is eliminated.

  • Publication number: 20040163646
    Abstract: A portable air temperature controlling device useful for warming air surrounding an aerosolized drug formulation. Warming the air of an aerosol makes it possible to reduce the diameter of aerosol particles produced by an aerosol generation device. Additionally, warming the air forces the diameter of the aerosol particles to be in the range required for systemic drug delivery independent of ambient conditions. Smaller particles can be more precisely targeted to different areas of the respiratory tract.

  • Publication number: 20040089290
    Abstract: Dosages of inhaled insulin are controlled within a narrow range by controlling the total volume of air inhaled by a patient. By repeatedly delivering aerosolized insulin with the same total inhaled volume of air, the amount of insulin delivered to the patient each time is consistent. A device for delivering insulin by inhalation is disclosed which device comprises a means for measuring inhaled volume and for halting inhalation at a pre-determined point. The device also comprises an adjustable means for applying various amounts of force to a container of formulation to expel different amounts of drug from the container based on the force applied.

  • Patent number: 6732943
    Abstract: Methods of generating pores in thin sheets of material, typically thin polymer films, are provided. The methods allow for generation of pores which uniformly penetrate the material. The method comprises laminating a thick film onto a thin film, then directing a laser source onto the thin film so as to form pores through the thin film. The increased stiffness conferred by the thick film reduces wrinkle formation in the thin film, resulting in uniform thickness of the thin film and consequent uniformity of pore depth. The invention further provides aerosolization containers and devices comprising membranes formed according to the invention.

  • Patent number: 6732954
    Abstract: A nozzle comprising a thin, flexible substantially planar polymeric film having a plurality of pores with structures allowing for generation of an aerosol at reduced extrusion pressure is disclosed. The pores can comprise at least two sections, or steps, in which the thickness of the membrane is reduced in stepwise fashion, or the pores can be tapered. Nozzles formed comprising pores having such structures permit aerosol generation at lower extrusion pressures, thereby allowing for decreased weight of aerosolization devices, increased efficiency, increased portability and increased battery life. The pore structures also allow for the use of thicker, more easily processed polymeric films in manufacturing while having a thinner, more efficient aerosolization area. The use of decreased extrusion pressures also results in increased uniformity in aerosol generation and improved reliability of other components.

  • Publication number: 20040062717
    Abstract: Formulations are disclosed as are aerosols created therefrom. The formulations are comprised of (a) a pharmaceutically active drug which does not ionize in solution; (b) an electrolyte; and (c) a solvent which is preferably water and/or ethanol. The electrolyte reduces electrostatic charging on particles of aerosol formed thereby enhancing characteristics of the aerosol particles which are important for efficient, repeatable intrapulmonary drug delivery.

  • Patent number: 6647987
    Abstract: The need for the delivery of insulin by injection can be reduced or eliminated by a method whereby an aerosolized insulin formulation is delivered to a patient's lungs and the rate at which the insulin is absorbed into the blood is increased by the use of an inhale-exhale breathing maneuver. Particles of insulin delivered to the surface of lung tissue will be absorbed into the circulatory system. The rate of absorption is enhanced by instructing the patient to inhale maximally and thereafter exhale maximally. The insulin is delivered to the patient from a hand-held, self-contained device which automatically releases an aerosolized burst of formulation. The device includes a sensor which is preferably electronic which measures inspiratory flow and volume which measurement can be used to control the point of drug release. The sensor can also assist the patient in the inhale-exhale maneuver.

  • Patent number: 6632419
    Abstract: The libido of adult human female patients is increased by the bolus delivery of a testosterone which is preferably dihydrotestosterone. The formulation is preferably aerosolized and inhaled into a patient's lungs where particles of testosterone deposits on lung tissue and then enter the patient's circulatory system. The patient's testosterone level is quickly enhanced well above baseline levels for a short period and subsides to baseline levels with normal metabolism thereby providing desired short term effects on enhanced libido without undesirable effects of long term enhanced testosterone levels. Additional formulations are provided including formulations for aerosolized delivery of sildenafil citrate which are delivered to male or female patients.

  • Patent number: 6624885
    Abstract: A method for inspecting small holes in a material is disclosed. The method comprises directing a light source through the holes in the material, and then focusing the light passing through the material onto a CCD detector. The focusing techniques allow for a reduction in the size of the image which must be inspected, thereby increasing sample throughput, while still allowing for detailed inspection of the hole number and quality. Methods of producing an aerosolization container and device comprising membranes which pass such an inspection are also provided.

  • Patent number: 6551542
    Abstract: A method for producing a nozzle useful in generating a fine aerosol for delivery of therapeutic or diagnostic agents is provided. The method comprises focusing a laser source onto a thin, preferably flexible material so as to form pores substantially through the material. The pores are formed to have an unflexed exit aperture diameter in the range of about 0.5 to about 25 microns, depending on the size of the aerosol particles desired for a particular application. The nozzle may have a variety of shapes and be distributed in a variety of patterns. An elevated area can be formed around the exit aperture of the nozzle in order to prevent intrusion of liquid into the nozzle.

  • Patent number: 6543442
    Abstract: A nozzle comprised of a thin, flexible membrane material having a plurality of pores is disclosed. In one embodiment, the pores have an unflexed exit aperture diameter in the range of about 0.5 to about 2 microns (preferably about 1 micron) and are positioned substantially uniformly in the material, preferably about 50 microns apart. The nozzle preferably has a conical or trumpet-shaped cross-section. In another aspect of the invention, the exit aperture of the nozzle is surrounded by an elevated area protruding above the substantially planar exit side of the membrane in order to prevent intrusion of liquid back into the nozzle. The nozzle can be used to form an aerosol containing a pharmaceutical composition from the exit side of the nozzle upon forcible application of the composition to the entrance side of the nozzle. This aerosol can be used to administer the pharmaceutical composition, for example, to the eye or to a selected portion of the respiratory tract.
