Definitions

  • the invention relates to a package for pharmaceutical compositions, mixtures or formulations for use in a powder inhaler.
  • the multi-dose powder inhalers contain the pharmaceutical composition, mixture or formulation either in the form of a powder supply from which the single dose is taken from a well by means of a built-in metering unit, or pre-metered packaged single doses which are either stored together in the device (e.g., in the form of packaged amounts in blisters) or are placed individually in the device for use (e.g., in the form of capsules).
  • the manner of packaging in which the powder formulation is present in the device is critical to the quality of the product and hence to its suitability for use by inhalation.
  • a chief objective of the packaging is to keep the chemical composition of the atmosphere inside the packaging constant, in order to prevent physical or chemical changes to the pharmaceutical composition, mixture or formulation, or to stabilise them.
  • in-use stability a distinction is made between stability directed to the short term, which the pharmaceutical composition, mixture or formulation has to have per se, even if it is not adequately protected by the packaging (“in-use stability”) and the long-term stability, i.e., the stability which has to be guaranteed for as long as the pharmaceutical composition, mixture or formulation is contained in the unopened package.
  • fine particle dose refers to the dose that reaches the patient's lungs.
  • the fine particle dose is influenced by the interactions of the micronised particles of active substance with one another and also the interactions with the excipients.
  • a package it is also necessary for a package to have a shape and an opening pattern (i.e., the places in the packaging which allow the blister to be opened by piercing or cutting) which enable an optimum air supply and hence optimum delivery of the pharmaceutical composition, mixture, or formulation.
  • Examples of multi-dose powder inhalers are known in the art. They are known for example from EP 0 703 800 B1 or EP 0 911 047 A1, which disclose a powder inhaler consisting of a cup-shaped lower part and an equally cup-shaped lid. After placing the capsule in the capsule holder, the patient can press an actuating member which is movable from a resting position and thereby interacts with at least one pin that can be pressed into the capsule holder. The capsule is pierced by the pin or pins and the drug is released.
  • DE 3348370 and DE 3336486 further disclose inhalers which contain a disc-shaped blister pack comprising a number of wells arranged in a circle.
  • the individual wells each contain a dose of a medicament powder intended for inhalation.
  • the wells are closed off on both sides by a sealing film, for example.
  • An air channel connects the opened well with the mouthpiece of the inhaler.
  • the inhaler of DE 3336486 will be described in more detail. It comprises a housing in which there is a chamber (supply chamber) comprising an air inlet and in which there is a disc-shaped round blister with medicament pouches packed therein.
  • the blister is loosely connected to a rotatable round disc.
  • Around the disc are formed holes which are axially in contact with the medicament pouches, i.e., the pouches and holes are located above and below one another.
  • the chamber has an air outlet.
  • the inhaler also has a piston which is arranged so that it can open a pouch of medicament by piercing it, so that the medicament is released into the chamber and can be breathed in through a mouthpiece.
  • the primary packaging is characterized in that it is in direct contact with the inhalable formulation.
  • the primary packaging may optionally be surrounded by a second, outer protection, the secondary packaging.
  • the primary packaging may be, for example, a capsule, a solid or flexible blister with wells or a disc comprising wells.
  • the secondary packaging may be a blister, a pouch, a bag or other container.
  • the secondary packaging generally totally encloses the primary packaging. Secondary packaging is used particularly when the primary packaging does not provide adequate protection from moisture.
  • the primary packaging and optionally the secondary packaging have the task of protecting the active substance and also the entire inhalable formulation from chemical or physical change, so that it remains stable for long periods.
  • the physical changes in question may be, in particular, changes which might affect the delivery of the intended dose of fine particles.
  • the choice of a suitable material for the packaging is determined by two factors. On the one hand the material must be able to perform the protective function required. On the other hand the material must be such that the packaging can be made into the form needed for use in the powder inhaler and can perform the function expected of it.
  • the problem underlying the present invention is to optimise the shape of the packaging, the piercing pattern of the packaging and the fill level of a pharmaceutical composition, mixture or formulation, so as to improve the delivery of a pharmaceutical composition, mixture or formulation.
  • the present invention therefore relates to packages for inhalable powders, which are optimised in their shape, piercing pattern and fill level with a pharmaceutical composition, mixture or formulation.
  • FIGS. 1-10 show, by way of example, the different shapes of a capsule or of an individual well of a blister (known over all as packaging means) and the corresponding piercing positions.

  • the invention relates to optimised packages as described above which allow improved air flow and hence improved delivery of a pharmaceutical composition, mixture or formulation by virtue of the shape of their opening pattern in their piercing pattern and the fill level with the pharmaceutical composition, mixture or formulation.
  • the packages consist of a capsule, a blister, a blister disc or a blister strip. These different forms (with the exception of the capsules) will hereinafter be referred to over all as blisters.
  • the capsule generally consists of two parts, a capsule body (body) and a capsule cap (cap), which fit telescopically inside one another.

  • the capsule material is non-digestible plastics or gelatine, particularly hard gelatine.
  • the blister disc may be, for example, a cylinder-like disc up to 5 mm high and up to 15 cm in diameter. In the disc are depressions or holes (wells) formed perpendicularly to the plane of the disc.
  • a disc of this kind may for example be placed in an inhaler according to DE 3348370 or DE 3336486.
  • An inhaler of this kind has a housing which contains the disc-shaped round blister with medicament pouches packed therein.
  • the inhaler comprises, inter alia, a pin which is arranged so that it can open one medicament pouch, so that the medicament is released into the chamber and can be breathed in through a mouthpiece.
  • the shape of the package according to the invention including the shape of the well is fundamentally determined by the powder inhaler which is to be used.
  • the packaging is teardrop-shaped or oval or in the shape of a figure of eight.
  • the inflow surfaces and outflow surface(s) are as far away from one another as possible.
  • the package which is a blister first of all comprises a base element consisting of a thermoplastic plastics and at least two wells separated from one another by a web.
  • the wells are open at least on one side, possible on two opposing sides. These openings are closed off in the packaging ready for use, e.g., by means of a sealing foil which is attached to the base element.
  • the package may consist of standard commercial materials. Preferably, it consists of a plastics material. Most preferably, the materials used as plastics selected from among the thermoplastic polymers such as, e.g., polystyrenes, polyolefins, polyamides, polyvinyl chlorides, polyethylenes, polycarbonate, polyester, polypropylene, polyethylene terephthalate or polyurethane. These have the necessary rigidity or mobility to enable them to perform the mechanical tasks of the primary packaging. Also suitable are, for example, natural substances such as gelatine or composite materials of plastics and metals, such as aluminium.

  • composition or processing can be found in the prior art, particularly EP599690, EP432438 or EP400460.
  • the fill level of the pharmaceutical composition, mixture or formulation in the package can be optimised and will depend on the flowability of the pharmaceutical composition, mixture or formulation.
  • flowability indicates the ability of the pharmaceutical composition, mixture or formulation to flow easily as a loose material.
  • ⁇ 1 is the solidification tension and ⁇ c is the bulk strength. Normally the flowability is determined using a ring shear device.
