摘要:
An aerosolization system includes a squeezable container having a resilient container body. The container is configured to deliver a unit dosage of a liquid when squeezed a single time. The system also includes an aerosolizer that is constructed of a housing defining a mouthpiece, and an aerosol generator disposed in the housing. The aerosol generator comprises a vibratable membrane having a front face and a rear face, and a vibratable element used to vibrate the membrane. Further, the housing includes an opening that is adapted to receive a unit dosage of the liquid from the container. The opening provides a liquid path to the rear face of the vibratable membrane.

One embodiment describes an insulin formulation that is specifically adapted for aerosolization. The formulation comprises a major amount of water and a minor amount of insulin. Further, the formulation is preservative free, without meta-cresol, cresol or phenol, to permit the formulation to be aerosolized using a vibrating aperture plate without substantial foaming of the insulin formulation.

The present invention provides active, hydrophilic polymer-modified derivatives of insulin. The insulin derivatives of the invention are, in one aspect, suitable for delivery to the lung and exhibit pharmakokinetic and/or pharmacodynamic properties that are significantly improved over native insulin.

摘要:
An aerosolization device comprises a chamber adapted to contain a powder pharmaceutical formulation, a lid at least partially covering the chamber, at least one piercing element forcible through the lid to provide access to the powder pharmaceutical formulation, and a shapeable surface extending from the chamber, the shapeable surface being adapted to undergo a shape change to form a conduit. The powder pharmaceutical formulation may be extracted from the chamber by a user inhaling through the conduit. In another version, the lid is removable from the chamber without the need for a piercing element.
摘要:
Systemic delivery of parathyroid hormone to a mammalian host is accomplished by inhalation through the mouth of a dispersion of an N-terminal fragment of PTH. It has been found that such respiratory delivery of the PTH fragment provides a pulsatile concentration profile of the PTH in the host's serum. PTH fragment compositions include dry powder formulations having the PTH present in a dry bulking powder, liquid solutions or suspensions suitable for nebulization, and aerosol propellants suitable for use in a metered dose inhaler.
摘要:
A device for accurately delivering aerosolized doses of a medicament disperses a measured amount of drug in a measured volume of carrier gas and transfers the resulting aerosol to a chamber prior to inhalation by a patient. The chamber is filled efficiently with the aerosol, and inhalation by the patient draws the aerosol dose into the lungs. This is followed by the inhalation of atmospheric air that will push the initial dose well into the lung interiors. The apparatus optimally includes a dose regulator, a counter, a clock, a dose memory and a signal to indicate when a dose is ready for inhalation. Optimal chamber designs are disclosed.
摘要:
A safety closure and container combination is disclosed. The container and closure each have mating lugs which cooperate with each other to move the closure toward the container when rotated in a first direction and to move the closure away from the container when moved in a second direction. Cooperating stop surfaces are provided on the closure and container which engage when the closure is rotated in a direction to move it away from the container so that it is necessary to move the closure toward the container to allow the stop surfaces to move past each other thereby allowing the closure to be removed from the container.
