The present disclosure relates to a medicament dispenser for dispensing medicament. The dispensing mechanism can include three steps to operate the medicament dispenser: Open, Dispense and Close.
Medicaments are administered to a patient by inhalation using dry powder dispenser devices. Such devices are often referred to as dry powder inhalers (DPI), and are used for the treatment and prophylaxis of respiratory diseases, including but not limited to asthma, chronic obstructive pulmonary disease (COPD) bronchitis and chest infection.
Generally described, dry powder inhalers carry medicament in reservoirs, capsules or blisters packages, and can otherwise carry medicament. The medicament carrier can include a blister strip containing a number of discrete doses of powdered medicament. Such devices can contain a mechanism of accessing these doses, either piercing means or means to peel a lid sheet away from a base sheet. The powdered medicament can then be accessed and inhaled. Such a mechanism may also be used for dispensing medicament in tablets, capsules, pellets or pucks form wherein peeling away the lid sheet from the base sheet reveals a particular medicament form such as tablet for removal and subsequent consumption, particularly for oral administration.
U.S. Pat. No. 5,873,360 discloses an inhalation device, wherein a cover is pivotal between an open position in which the mouthpiece is exposed and a closed position in which it is not. In operation, the user moves the cover to its open position and then presses on the finger tab of the lever to cause it to move as the lever pivots. The lever associated with the finger tab, actuates the gear mechanism as the finger tab is slided from end to end. Therefore, the blister strip is advanced, one blister is opened, and one dose of the dry powder medicament contained in the blister cavity, become ready for the inhalation. The cover is held stationary as the body is rotated anticlockwise. As the cover of the device is not directly connected to the lever mechanism, the user needs to first move the cover and then lever and thus more number of steps are required to operate the device.
U.S. Pat. No. 8,161,968 discloses a medicament dispenser for containing plural elongate form medicament carriers, wherein said medicament dispenser comprises a movable cover for the outlet which is movable from an at rest position, in which the cover covers the outlet, to a primed position and then an actuated position to uncover the outlet, and couples to the dispensing mechanism such that: movement of said cover from the primed position to the actuated position actuates one or more components of the dispensing mechanism, and movement of said cover from the at rest position to the primed position does not actuate said one or more components of the dispensing mechanism.
U.S. Pat. No. 8,746,242 discloses a medicament dispenser for use with at least one medicament carrier carrying multiple distinct medicament portions, said medicament dispenser comprising (a) a dispensing mechanism actuable for dispensing the distinct medicament portions carried by said at least one medicament carrier; (b) a mouthpiece; and (c) a cover for said mouthpiece, said cover being movably mounted to the dispenser for sequential movement from a first position, in which said mouthpiece is covered, to a second position, in which said mouthpiece is part-uncovered, to a third position in which said mouthpiece is uncovered; wherein said cover is adapted to couple with said dispensing mechanism such that movement of the cover from the first position to the second position does not result in actuation of the dispensing mechanism, but any further movement of the cover from the second position to the third position results in actuation of the dispensing mechanism.
In operation, it is potentially desirable that dispensing mechanism comprises minimum number of steps to operate medicament dispenser. It is also potentially desirable that dispensing mechanism offers a continuous movement of the outer cover and without any second/intermediate position during opening and closing processes so as to avoid any confusion to the user. Further, increase in number of steps will increase complexity and cost associated with development of inhalation device.
In order to overcome such problems, the present disclosure describes a medicament dispenser which is cost-effective and which is used for dispensing medicament in reliable and easy way. Thus, the user actuates the mechanism with minimum possible steps to advance the medicament carrier thereby causing the next discrete dose of medicament to be made available for dispensing.

In some embodiments, the medicament may in aspects, be a mono-therapy (i.e. single active medicament containing) product or it may be a combination therapy (i.e. plural active medicaments containing) product. Suitable medicaments or medicament components of a combination therapy product are typically selected from the group consisting of anti-inflammatory agents (for example a corticosteroid particularly inhaled corticosteroid (ICS) or an NSAID), anticholinergic agents (for example, an M1, M2, M1/M2 or M3 receptor antagonist particularly long-acting muscarinic antagonist (LAMA), other β2-adrenoreceptor agonists particularly long-acting β2-agonist (LABA), anti-infective agents (e.g. an antibiotic or an antiviral), and antihistamines. All suitable combinations are envisaged. The present invention also provides combination therapy product typically double or triple LAMA, LABA, ICS combinations.
Suitable anti-inflammatory agents include corticosteroids and NSAIDs. Suitable corticosteroids are those oral and inhaled corticosteroids and their pro-drugs which have anti-inflammatory activity. Examples include methyl prednisolone, prednisolone, dexamethasone, fluticasone propionate, fluticasone furoate, 6α,9α-difluoro-17α-[(2-furanylcarbonyl)oxy]-11β-hydroxy-16α-methyl-3-oxo-androsta-1,4-diene-17β-carbothioic acid S-fluoromethyl ester, 6α, 9α-difluoro-11β-hydroxy-16α-methyl-3-oxo-17α-propionyloxy-androsta-1,4-diene-17β-carbothioic acid S-(2-oxo-tetrahydro-furan-35-yl) ester, beclomethasone esters (e.g. the 17-propionate ester or the 17,21-dipropionate ester), budesonide, flunisolide, mometasone esters (e.g. the furoate ester), triamcinolone acetonide, rofleponide, ciclesonide, butixocort propionate, RPR-106541, and ST-126.

Suitable phosphodiesterase 4 (PDE4) inhibitors include compounds that are known to inhibit the PDE4 enzyme or which are discovered to act as a PDE4 inhibitor, and which are only PDE4 inhibitors, not compounds which inhibit other members of the PDE family as well as PDE4. Generally it is preferred to use a PDE4 inhibitor which has an IC50 ratio of about 0.1 or greater as regards the IC50 for the PDE4 catalytic form which binds rolipram with a high affinity divided by the IC50 for the form which binds rolipram with a low affinity. For the purposes of this disclosure, the cAMP catalytic site which binds R and S rolipram with a low affinity is denominated the “low affinity” binding site (LPDE 4) and the other form of this catalytic site which binds rolipram with a high affinity is denominated the “high affinity” binding site (HPDE 4). This term “HPDE4” should not be confused with the term “hPDE4” which is used to denote human PDE4.
A method for determining IC50s ratios is set out in U.S. Pat. No. 5,998,428 which is incorporated herein in full by reference as though set out herein. See also PCT application WO 00/51599 for another description of said assay.
Suitable PDE4 inhibitors include those compounds which have a salutary therapeutic ratio, i.e., compounds which preferentially inhibit cAMP catalytic activity where the enzyme is in the form that binds rolipram with a low affinity, thereby reducing the side effects which apparently are linked to inhibiting the form which binds rolipram with a high affinity. Another way to state this is that the preferred compounds will have an IC50 ratio of about 0.1 or greater as regards the IC50 for the PDE4 catalytic form which binds rolipram with a high affinity divided by the IC50 for the form which binds rolipram with a low affinity.
A further refinement of this standard is that of one wherein the PDE4 inhibitor has an IC50 ratio of about 0.1 or greater; said ratio is the ratio of the IC50 value for competing with the binding of 1 nM of [3H]R-rolipram to a form of PDE4 which binds rolipram with a high affinity over the IC50 value for inhibiting the PDE4 catalytic activity of a form which binds rolipram with a low affinity using 1 muM[3H]-cAMP as the substrate.
Most suitable are those PDE4 inhibitors which have an IC50 ratio of greater than 0.5, and particularly those compounds having a ratio of greater than 1.0. Preferred compounds are cis 4-cyano-4-(3-cyclopentyloxy-4-methoxyphenyl)cyclohexan-1-carboxylic acid, 2-carbomethoxy-4-cyano-4-(3-cyclopropylmethoxy-4-difluoromethoxyphenyl)cyclohexan-1-one and cis-[4-cyano-4-(3-cyclopropylmethoxy-4-difluoromethoxyphenyl)cyclohexan-1-ol]; these are examples of compounds which bind preferentially to the low affinity binding site and which have an IC50 ratio of 0.1 or greater.
Other suitable medicament compounds include: cis-4-cyano-4-[3-(cyclopentyloxy)-4-methoxyphenyl]cyclohexane-1-carboxylic acid (also known as cilomalast) disclosed in U.S. Pat.

Suitable antihistamines (also referred to as H1-receptor antagonists) include any one or more of the numerous antagonists known which inhibit H1-receptors, and are safe for human use. All are reversible, competitive inhibitors of the interaction of histamine with H1-receptors. Examples include ethanolamines, ethylenediamines, and alkylamines. In addition, other first generation antihistamines include those which can be characterized as based on piperizine and phenothiazines. Second generation antagonists, which are non-sedating, have a similar structure-activity relationship in that they retain the core ethylene group (the alkylamines) or mimic the tertiary amine group with piperizine or piperidine. Exemplary antagonists are as follows: Ethanolamines: carbinoxamine maleate, clemastine fumarate, diphenylhydramine hydrochloride, and dimenhydrinate. Ethylenediamines: pyrilamine amleate, tripelennamine HCl, and tripelennamine citrate. Alkylamines: chlropheniramine and its salts such as the maleate salt, and acrivastine.

Piperidines: Astemizole, levocabastine HCl, loratadine or its descarboethoxy analogue, and terfenadine and fexofenadine hydrochloride or another pharmaceutically acceptable salt.
Azelastine hydrochloride is yet another Hireceptor antagonist which may be used in combination with a PDE4 inhibitor. Particularly suitable anti-histamines include methapyrilene and loratadine. In respect of combination products, co-formulation compatibility is generally determined on an experimental basis by known methods and may depend on chosen type of medicament dispenser action.
The medicament components of a combination product are suitably selected from the group consisting of anti-inflammatory agents (for example a corticosteroid or an NSAID), anticholinergic agents (for example, an M1, M2, M1/M2 or M3 receptor antagonist), other β2-adrenoreceptor agonists, anti-infective agents (e.g. an antibiotic or an antiviral), and antihistamines. All suitable combinations are envisaged.
Suitably, the co-formulation compatible components comprise a β2-adrenoreceptor agonist and a corticosteroid; and the co-formulation incompatible component comprises a PDE-4 inhibitor, an anti-cholinergic or a mixture thereof. The β2-adrenoreceptor agonists may for example be salbutamol (e.g., as the free base or the sulphate salt) or salmeterol (e.g., as the xinafoate salt) or formoterol (e.g., as the fumarate salt). The corticosteroid may for example, be a beclomethasone ester (e.g., the dipropionate) or a fluticasone ester (e.g., the propionate) or budesonide.
In one example, the co-formulation compatible components comprise fluticasone propionate and salmeterol, or a salt thereof (particularly the xinafoate salt) and the co-formulation incompatible component comprises a PDE-4 inhibitor, an anti-cholinergic (e.g. ipratropium bromide or tiotropium bromide) or a mixture thereof.

Medicament dispensers, as disclosed herein, have a variety of structural configurations and can be used for dispensing powders, tablets, capsules, pellets or pucks, or mixtures thereof for nasal, pulmonary or oral administration. In particular, the medicament dispensers can be used to dispense a powder comprising one or more active pharmaceutical ingredient(s)(API) and optionally, one or more micronized or non-micronized pharmaceutically acceptable carrier(s) and/or excipient(s), wherein the dispensing mechanism comprises of three steps to operate the medicament dispenser: Open, Dispense and Close.
Generally, powdered medicament particles suitable for delivery to the bronchial or alveolar region of the lung have an aerodynamic diameter of less than 10 micrometers, preferably less than 6 micrometers. Other sized particles may be used if delivery to other portions of the respiratory tract is desired, such as the nasal cavity, mouth or throat. The medicament may be delivered as pure drug, but more appropriately, it is preferred that medicaments are delivered together with one or more excipients or carriers which are suitable for inhalation. Suitable excipients or carriers include organic excipients such as polysaccharides (i.e. starch, cellulose and the like), lactose, glucose, mannitol, amino acids, magnesium stearate and maltodextrins, and inorganic excipients such as calcium carbonate or sodium chloride. In preferred embodiment, carrier or excipient is lactose.
Particles of powdered medicament and/or excipient may be produced by conventional techniques, for example by micronisation, milling or sieving. Additionally, medicament and/or excipient powders may be engineered with particular densities, size ranges, or characteristics. Particles may comprise active agents, surfactants, wall forming materials, or other components considered desirable by those of ordinary skill.
The medicament dispensers described herein can be used for the treatment and prophylaxis of respiratory diseases, including but not limited to asthma, chronic obstructive pulmonary disease (COPD) bronchitis or chest infection.
The medicament dispenser can be a hand-held dispenser and can be operated by a single hand.
The medicament dispenser can be of circular form, non-circular form, an elongate form, an elliptical form, or other shapes.
The medicament dispenser can include a flat surface or a resting surface. In some embodiments, at least a portion of the medicament dispenser can be shaped for ease of grip by the user.
The medicament dispenser can be an inhalation device, in particular a dry powder inhaler (DPI).
The medicament dispenser can include a diskette assembly or a housing.
In some embodiments, the diskette assembly can include a base cover and a top cover for enclosing a medicament carrier, a medicament carrier advancing mechanism, inner housing assembly, dose indicator or dose counter and a lever. The top cover can lock with the base cover to form a flow channel (or opening). In some embodiments, the top cover can lock permanently with the base cover through welding techniques.
The flow channel can be in the form of a mouthpiece for oral use. In some embodiments, the flow channel can be in the form of a nozzle for insertion into the nasal cavity of a patient. In some embodiments, the flow channel can be in the form of exit channel if the medicament is in solid form such as tablets or capsules.
In some embodiments, the flow channel is a single outlet, which communicates with all of the distinct medicament on their release. Communication can be for example, via a common air channeling means (e.g. formed as an air-pipe or common manifold). In another embodiment, the flow channel and/or channeling device is shaped to encourage mixing of drug as a result of the airflow created by inhalation by the patient.
The term ‘mouthpiece’ is used to mean an element through which the patient may inhale. In one aspect, the inhalation is by oral means with the patient placing the mouthpiece in its mouth. In an alternative aspect, the mouthpiece comprises a nozzle for insertion into the nasal cavity of a patient.
In some embodiments, the mouthpiece can snap on the diskette assembly. The mouthpiece can further include a mouthpiece interface opening. The mouthpiece interface opening and flow channel can allow the distinct medicament portions to be dispensed to the user.
The diskette assembly can be of circular form, non-circular form, an elongate form or an ovular form. The diskette assembly can include a flat surface or a resting surface. In some embodiments, at least a portion of the diskette assembly can be shaped for ease of grip by the user.
The diskette assembly can include at least one medicament carrier carrying multiple distinct medicament portions.
In some embodiments, the diskette assembly can include a single or plural medicament carriers. The plural elongate form medicament carriers may be provided in any suitable configuration. One suitable configuration is the ‘side-by-side’ configuration, in which for example, two carriers (e.g. two coiled blister strips) are arranged to lie in sideways alignment with each other. Another suitable configuration is the ‘double-decker’ configuration, in which for example, two carriers (e.g. two coiled blister strips sharing the same coiling axis) are arranged to lay one on top of each other in the dispenser. In some embodiments, the plural medicament carriers can be a first medicament carrier and a second medicament carrier. The plural medicament carriers can be separated by a deck separator or deck separators. The deck separator can be used to allow the independent movement of the medicament carriers with no contact between medicament carriers and no friction between medicament carriers due to mutual contact. The deck separators can be locked in the inner housing assembly by locking heads.
In some embodiments, the multiple distinct dose portions can be provided to each carrier in uniform series. In particular, the spacing (i.e. pitch) between each dose portion is uniform throughout the series. In other aspects however, the spacing (i.e. pitch) may vary throughout the series (i.e. be non-uniform). In one aspect, the spacing (i.e. pitch) between each dose portion is equivalent for each carrier of the dispenser. That is to say, each medicament carrier is equivalently pitched. In other aspects, the spacing between each dose portion is non-equivalent for each carrier of the dispenser. Such variation of the spacing (i.e. pitch) from carrier to carrier can be used to enable flexibility in (combination) dosage patterns. In one particular example, the spacing (i.e. pitch) of a first carrier is arranged to be half that of a second carrier. This arrangement is beneficially employed where the dose interval (i.e. time between doses) of the medicament carried by the first carrier is twice that of the medicament carrier by the second carrier (e.g. in a twice daily/once daily type dosage regime).
In some embodiments, the medicament carrier carrying multiple distinct medicament portions can be in the form of a strip or tap. In some embodiments, the medicament carrier can be a reel of blisters containing multiple distinct blister pockets such as a blister pack or a blister strip. In some embodiments, the medicament carrier can be a blister pack in a laminate form. In some embodiments, access to the medicament(s) comprised within the blister pockets of reel of blisters is by any suitable access means including tearing, piercing or peeling apart the relevant blister pockets. The medicament carrier can be wound around a post of the inner housing assembly. One end of the medicament carrier can be in the form of a sealed loop that can be placed in a blister post of a winder ratchet. The other end of the medicament carrier can be placed in a slit of a wrapping wheel.
In some embodiments, the reel of blisters can be in the form of a peelable blister strip which includes blister pockets wherein each of the blister pockets has one dose of the medicament. In some embodiments, each blister pocket comprises or forms two or more separate chambers or compartments, for example two compartments. The compartments are formed by a partition wall dividing the blister pocket. In some embodiments, the peelable blister strip comprises a base sheet in which blisters are formed to define pockets therein for containing distinct medicament dose portions and a lid sheet or lamination which is hermetically sealed to the base sheet except in the region of the blisters in such a manner that the lid sheet and the base sheet can be peeled apart. The blister pocket having compartments may be covered by common lid sheet. The lamination of the blister pockets is peeled via a constant tension torque applied by the winding assembly.
In some embodiments, the diskette assembly can include at least one piercing element for puncturing the lamination or lid sheet of the blister pocket. In some embodiments, the diskette assembly comprises at least one piercing elements for puncturing the lamination or lid sheet of the compartments of one blister pocket simultaneously, for example two piercing elements.
In some embodiments, the blister pocket from each of the reel of blisters can include medicament comprising one or more active pharmaceutical ingredient(s). In some embodiments, the blister pocket can include medicament comprising a single active pharmaceutical ingredient. In some embodiments, the blister pocket can include medicament comprising two or more active pharmaceutical ingredients. For example, the blister pocket can include medicament comprising two or three active pharmaceutical ingredients.
In some embodiments, the diskette assembly can include a lever which comprises an arcuate wall with a lever surface, a center and an arm which extends inwardly from the wall and carries an arcuate array of teeth at its distal end (i.e. lever teeth).
In some embodiments, the diskette assembly can include a lever which comprises an arcuate wall with a driver, a center and an arm which extends inwardly from the wall and carries an arcuate array of teeth at its distal end (i.e. lever teeth).
In some embodiments, the diskette assembly can include a lever which comprises an arcuate wall with a bar, a center and an arm which extends inwardly from the wall and carries an arcuate array of teeth at its distal end (i.e. lever teeth).
In some embodiments, the lever can include a lever flap that uncovers and covers the mesh of the inner housing assembly during actuation and release.
In some embodiments, the diskette assembly can include a central gear. In further embodiment, the central gear can include a boss, a bearing and teeth.
In some embodiments, the diskette assembly can include an idle gear. In further embodiment, the idle gear comprises teeth.
The teeth of the central gear fix with the teeth of the idle gear to actuate the medicament carrier advancing mechanism.
In some embodiments, the inner housing assembly can house the medicament carrier. The inner housing assembly can include a mesh or meshes that allow de-agglomeration of the medicament. During dosing operation, the cuvette on the blister cuvette is aligned with the mesh which can allow the medicament to be dispensed through the flow channel and mouthpiece interface opening to the user.
In some embodiments, the medicament dispenser comprises an outer cover. The outer cover can be mounted to the diskette assembly by a suitable mounting such as a pivot mounting wherein the outer cover pivots around the diskette assembly. In some embodiments, the outer cover can pivots about studs of the diskette assembly via the mounting holes.
In some embodiments, the medicament dispenser further comprises an inner cover. The outer cover and the inner cover can be mounted to the diskette assembly by a suitable mounting such as a pivot mounting wherein the outer cover and the inner cover pivot around the body of the diskette assembly. In another embodiment, the inner cover acts as hinge to the outer cover. The inner cover also pivots about studs on the diskette assembly.
In some embodiments, the outer cover can be adapted to couple with the lever and the medicament carrier advancing mechanism.
