摘要:
The invention discloses a method and a tool for exact metering and volumetric filling of finely divided dry powder medicament doses into preformed containers, whereby the doses and containers are adapted for administration by inhalation using a dry powder inhaler (DPI). A filling tool illustrating the invention includes at least one receptacle (10). The shape and size of a receptacle may vary depending on the size and mass of the powder load to be metered. A stretched woven filter (106) is positioned between the second opening of the receptacle (10) and a suction nozzle (13), using flexible seals at joints to stop air and powder leakage. The shape may be circular or elliptical, the wideness and depth, i.e. the volume, is adapted to the intended load and the method of filling and unloading.
摘要:
A medical product containing an accurately metered dose of a GLP-1 medicament intended for pulmonary inhalation put into a moisture-tight, high barrier seal container. The medical product optionally also contains a dose of insulin. The container is preferably adapted for application into a dry powder inhaler. The dose loaded in the container is intended for a prolonged delivery by inhalation to the deep lung where the active ingredients are absorbed into the system. Optionally the medical product also may comprise at least one biologically acceptable excipient.

摘要:
A method and an apparatus for exact metering and volumetric filling of dry powder medicament doses into preformed containers, which are adapted for administration by a dry powder inhaler. The filling apparatus includes at least a bulk powder source, a feeding chamber, and a receptacle providing the volume for a specified load mass of dry powder. The bulk powder source releases a portion of powder discontinuously to the feeding chamber, but is disconnected from the feeding chamber and receptacle during the filling operation. The filling apparatus further presents a plane surface in contact with the movable feeding chamber and provides a hard-wearing, low friction coating for reducing dynamic friction and powder retention.

摘要:
The invention discloses a metered medication dose of a dry powder protein medicament, particularly a peptide medicament, intended for inhalation by use of an adapted dry powder inhaler. An active peptide agent is presented in a pure, natural, crystalline, micronized, dry powder form. A dose comprises at least one such peptide powder and may optionally comprise at least one biologically acceptable excipient in dry powder form. The dose does not include any substances that are intended to change one, some or all properties of the at least one peptide with an object of improving the stability or systemic absorption of the active peptide or peptides deposited.
摘要:
A medicament container for carrying a metered, finely divided, dry powder medication dose is disclosed. The medicament container, which is intended for administration by a dry powder inhaler device, constitutes a pod presents a bottom surface acting as a dose bed adapted for receiving a metered medication dose. The metered dose, carried by the pod, is protected from foreign matter, particularly moisture, after a sealing of the pod with a high barrier seal foil, which transforms the pod into a high barrier container. Furthermore the pod is formed such that the pod sealing foil can be slit open from a point of penetration at a first pod end to a point of exit at a second pod end by a cutter set in motion relative to the pod.
摘要:
A dry powder medicament preparation is disclosed. Also methods of forming and loading metered doses of the preparation into dose containers intended for insertion into a dry powder inhaler are disclosed. The preparation is adapted for a dose forming process, which may be based on volumetric filling or electro-dynamic deposition of the powder particles, such that a metered dose of the preparation is characterized by having at least one load of held-together particles joined in a macrostructure of predefined dimensions and presenting an intended mechanical strength. The pharmacologically active ingredient presents at least 50% by mass of particles in a typical aerodynamic diameter range from 1 to 5 μm. Furthermore, a dose thus formed is then loaded into a high barrier container.
摘要:
The invention relates to a method for enclosing a metered, dry powder medication dose comprising at least one active pharmaceutical ingredient (API) and a metered dose of at least one dry powder excipient in a common space of a dose container. The deposited doses in the common dose container constitute a medical product. The method and the medical product are effective in raising the emitted medication dose output and improving the therapeutic efficacy when the doses are delivered together from a dry powder inhaler.
