  • Patent number: 7278419
    Abstract: The need for the delivery of insulin by injection can be reduced or eliminated by delivering aerosolized insulin. Repeatability of dosing is obtainable by using either regular insulin or monomeric insulin. When delivering insulin (not monomeric) by inhalation, the total inhaled volume should be about the same at each delivery to obtain repeatable results. The patient can be coached (by teaching) to inhale a given amount of air and can also be coached (by teaching) to inhale at a given flow rate. Further, the rate at which blood glucose is lowered is increased by the use of monomeric insulin. Particles of insulin and monomeric insulin delivered to the surface of lung tissue will be absorbed into the circulatory system. A dry powder or a liquid insulin formulation is delivered to the patient from a mechanical or electronic hand-held, self-contained device.

  • Patent number: 7244714
    Abstract: Methods and devices for delivering aerosolized formulations containing polynucleotides to specified regions within a subject's respiratory tract are disclosed. The methods find use in the delivery of ribozymes, antisense polynucleotides, and DNA and RNA expression vectors into airway epithelial cells, alveoli, pulmonary macrophages and other cells in the respiratory tract (including the oropharynx, nose, nasopharynx). These methods may be used for optimization of transfection efficiency and expression in vivo, and for in vivo expression, for example for generating an immune response, or inducing immunological tolerance.

  • Publication number: 20060124125
    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.

  • Publication number: 20060093556
    Abstract: The need for the delivery of insulin by injection can be reduced or eliminated by delivering an aerosolized monomeric insulin formulation. Repeatability of dosing and more particularly the repeatability of the blood concentration versus time profile is improved relative to regular insulin. The blood concentration versus time profile is substantially unaffected by specific aspects of the patient's breathing maneuver at delivery. Further, the rate at which blood glucose is lowered is increased by the use of monomeric insulin. Particles of insulin and in particular monomeric insulin delivered to the surface of lung tissue will be absorbed into the circulatory system. The monomeric insulin may be a dry powder but is preferably in a liquid formulation delivered to the patient from a hand-held, self-contained device which automatically releases an aerosolized burst of formulation.

  • Patent number: 7018825
    Abstract: The present invention relates to the use of calcium ion and/or sugars to minimize thermal aggregation of DNase and to the use of calcium ion to stabilize liquid solutions of DNase, the solutions having a pH of less than neutral. DNase is the active pharmaceutical principle and the solutions may contain other pharmaceutically acceptable excipients making them suitable for pharmaceutical administration. In the first instance, calcium ion/sugar minimizes the effects of thermal aggregation in the solution. In the second aspect, calcium ion stabilizes the lower pH solutions from protein precipitation.

  • 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.
