Provided herein are product containers, including but not limited to child-resistant product dispensers, and methods of use thereof. In some particular embodiments, provided herein are child-resistant medication dispensers, and methods of use thereof for administering medications to individuals that may suffer from manual dexterity problems.
Since about 1973, U.S. federal regulations promulgated under the Poison Prevention Packaging Act have required that prescription drugs intended for oral administration to humans comply with certain “child-resistant” packaging requirements unless specifically exempted. Generally speaking, child-resistant packaging is specially designed or constructed to be difficult for children under 5 years of age to open. Ideally, such child-resistant packaging is also designed so as not to present undue difficulties for patients accessing their medication. However, child-resistant packaging can sometimes pose a challenge for adults, particularly elderly or infirm individuals or those with impaired motor skills, e.g., those afflicted with neurological or muscular disorders.
Moreover, certain illnesses can make common pharmaceutical delivery vehicles, such as pills, capsules or tablets difficult for individuals to ingest. For example, many illnesses such as Parkinson's Disease, Duchenne Muscular Dystrophy and Amyotrophic Lateral Sclerosis (ALS) are accompanied by difficulties in swallowing (dysphagia).
Unfortunately, some individuals that are prescribed medications to treat a disease or disorder (e.g., Parkinson's Disease or related symptoms) also suffer from poor manual dexterity (e.g., hand tremors, decreased coordination between hands or loss of fine motor control skills) and find it difficult to open child-resistant drug containers, generally. These difficulties can be compounded when the medication is in the form of a thin strip medication. Thus, there is a need for a child-resistant device, and methods of use thereof, for administering medications to individuals that may suffer from manual dexterity problems.

In one aspect, methods of treating a subject afflicted with a neurological condition are disclosed comprising the steps of: providing at least one sealed pouch containing a medication, folding a tray around the pouch such that the tray supports the pouch, placing the tray and supported pouch inside a container such that the tray is engaged by the container in a manner that impedes removal of the tray, and securing the container with a cap configured to close the opening of the container, thereby allowing the subject to remove the cap and obtain an individual pouch by reaching into the container and pulling the pouch from its supporting tray and further permitting the subject to open the pouch and administer to themselves the medication.
In some embodiments, the cap is a child-resistant cap and the method further comprises releasing the interlocking engagement of the cap and container. In some embodiments, the neurological condition is Parkinson's Disease. In some embodiments, the neurological condition is an off episode associated with Parkinson's Disease. In some embodiments, the medication comprises a thin strip medication deployed within the pouch. In some embodiments, the method further comprises opening the pouch by pulling on opposing tabs of the pouch to separate the pouch into at least two sheet elements and allow the subject to access the thin strip medication deployed between the sheet elements. In some embodiments, the medication comprises apomorphine or a pharmaceutically acceptable salt thereof. In some embodiments, the apomorphine or a pharmaceutically acceptable salt thereof is formulated for sublingual release and the method permits the subject to place the thin strip medications under their tongue.
In order that the disclosure may be well understood, there will now be described various forms thereof, given by way of example, reference being made to the accompanying drawings, with like numbers used in the figures to refer to like components, elements, portions, regions, openings, apertures, etc., in which:
Described herein are product containers, including but not limited to child-resistant product dispensers, and methods of use thereof, for providing products, such as medications, to individuals that may suffer from manual dexterity problems. Embodiments disclosed herein may be particularly useful in dispensing thin strip medications, such as orally dissolving medications intended for sublingual application.
In some embodiments, a device is provided, e.g., a product dispenser, comprising a container having an opening and an inner chamber, a cap configured to close the opening (e.g., mouth) of the container and provide a child-resistant locking engagement with the container, and a tray deployable in the chamber of the container and configured to hold at least one pouch carrying a dose of medication. The tray can comprise a support configured to hold one or more pouches when the tray and pouches are deployed within the container.
For example, the support can be a rail onto which the pouches can be individually coupled to facilitate dispensation of one pouch at a time by pulling the pouch from the rail. Each of the pouches can comprise an opening for attachment to the rail. In one embodiment, the tray can have a first spar and a second spar on opposing wings of the tray that engage with each other to form the rail when the tray is folded about a hinge portion and deployed within the chamber of the container. By way of further example, one of the spars can have a male end and the other can have a female end such that that can be joined together to form the rail. Alternatively, or in addition, the spars can be joined together by a snap-fasten connection. In another embodiment, a single spar can be used to form the rail and the tray can be designed such that, upon folding, the spar spans a substantial portion of the container width. The single spar can extend from one wing of the tray and connect with a slot, snap-fasten or other joinder mechanism on the other wing of the tray when the tray is folded about a hinge portion.
In certain embodiments, the openings of the pouches can be larger than the thickness of the rail such that the pouches can extend partially out of the opening of the container when the container is uncapped and inverted.
Preferably, the tray is foldable to facilitate its insertion into the chamber of the container, e.g., the tray can comprise at least two arms and a hinge about which the arms can fold. Each arm can comprise an end portion or flange configured to engage an inner rim of the container to impede removal of the tray after insertion into the chamber of the container. The end portion can be curved or otherwise shaped to extend circumferentially along the container rim such that it subtends an angle of at least 10 degrees, or at least 20 degrees, or at least 30 degrees or at least 40 degrees.
In certain embodiments, the container can comprise at least one post that protrudes inwardly into the chamber of the container to engage the tray when deployed therein, and the tray comprises an opening for receiving the post. The tray opening can be a longitudinal slot that permits limited longitudinal movement of the tray within the chamber such that the tray and associated pouches can extend partially out of the opening of the container when the container is uncapped and inverted.
The engagement of the cap and container can be unlocked by a “quarter-turn” action, “push and twist” action or by a “squeeze and twist” action or any other of numerous well-known similar child-resistant engagement mechanisms.
The devices of the present disclosure are preferably capable of supporting a plurality of pouches with each pouch containing a single dose of thin strip medication, e.g., a thin strip orally-dissolvable medication.
In other embodiments of the disclosure, methods of dispensing medication are disclosed that can comprise the steps of providing at least one sealed pouch containing a dose of medication, folding a tray around the pouch such it supports the pouch, placing the tray and supported pouch inside a container such that the tray is engaged by the container in a manner that impedes removal of the tray, and securing the container with a cap configured to close the opening of the container and provide a child-resistant locking engagement with the container, whereby an adult user of the device can remove the cap and obtain an individual pouch by reaching into the container and pulling the pouch from its supporting tray.
In certain embodiments of the inventive methods, the tray comprises a support configured to hold a plurality of pouches when the tray and pouches are deployed within the container. The support can be a rail onto which the pouches can be individually coupled to facilitate dispensation of one pouch at a time by pulling the pouch from the rail. Each of the pouches can comprise an opening for attachment to the rail. Preferably, the openings of the pouches are larger than the thickness of the rail such that the pouches can extend partially out of the opening of the container when the container is uncapped and inverted.
The tray can comprise a first spar and a second spar that engage with each other to form the rail when the tray is deployed within the chamber of the container, and the step of folding the tray can further comprise forming the rail such that it passes through a hole in the pouch. By way of example, one of the spars can have a male end and the other can have a female end. Folding the tray causes the first and second spars to join together to form the rail. The first and second spars can also be configured to snap-fasten together to form the rail.
The methods of the disclosure can be practiced with a tray that is foldable along a hinge region to facilitate insertion of the tray into the chamber of the container. For example, the tray can comprise at least two arms and a hinge about which the arms can fold, and the step of placing the tray inside the container further comprises placing the hinge region along a bottom surface of the container. Each arm further can have an end portion or flange configured to engage an inner rim of the container to impede removal of the tray after insertion into the chamber of the container. The end portion of one or both arms can also be shaped to extend circumferentially along the container rim such that it subtends an angle of at least 10 degrees, or at least 20 degrees, or at least 30 degrees, or at least 40 degrees.
The methods can also be practiced with a container having at least one post that protrudes inwardly into the chamber of the container to engage at least one opening in the tray. The step of placing the tray inside the container further comprises placing the tray such that the tray opening receives the post. In certain embodiments, the tray opening can be a longitudinal slot that permits limited longitudinal movement of the tray within the chamber such that the tray and associated pouches can extend partially out of the opening of the container when the container is uncapped and inverted.
In certain embodiments, the container mouth can further comprise one or more “Thumb-notches” to allow the user more accessibility. In certain preferred embodiments, two thumb-notches opposite of one another are provided in the container mouth. The thumb-notches can be of equal size or one notch smaller than the other. The thumb-notches can give the end-user more access to grabbing and removing a pouch. In these embodiments it can further be advantageous for the cap to have two downward extending flaps (or one flap in the case of a single thumb-notch configuration) to provide closure of the mouth when the cap and container are in the closed or “locked” position.
The methods disclosed herein are preferably practiced to support a plurality of pouches with the tray inside the container where each pouch contains a dose of thin strip medication, e.g., a thin strip orally dissolvable medication.
It should be noted that, as used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. Thus, for example, reference to a composition containing “a support” includes two or more supports. It should also be noted that the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.
It should also be noted that, as used in this specification and the appended claims, the phrase “configured” describes a system, apparatus, or other structure that is constructed or arranged to perform a particular task or adopt a particular configuration. The phrase “configured” can be used interchangeably with other similar phrases such as arranged and configured, constructed and arranged, constructed, manufactured and arranged, adapted, and the like.
The term “child-resistant,” as used herein with reference to a cap or the combination of a cap and container, is intended to broadly encompass closure mechanisms designed or constructed to be difficult for children under 5 years of age to open. For example, the engagement of the cap and container can be unlocked by a “push and twist” action, a “quarter turn action,” or a “squeeze and twist” action, or by any one of numerous other, well-known, child-resistant closures.
The term “spar” as used herein is intended to encompass any element that provides support for a product. Preferably, the spar serves as a rail either by itself or in conjunction with another spar. For example, the spar can be a protrusion, post, bar, pole, or beam formed on, or attached to, at least one arm of a tray.
The term “snap-fasten” as used herein is intended to encompass any one of numerous interlocking fastener mechanisms for joining structures (e.g., spars) together. For example, in the case of a first spar having a male end and a second spar having a female end, a annular ridge or groove can be formed on the inside of the female spar and a mating annular groove or ridge is formed on the outside of the male spar. More generally, a snap fastener can take the form of any protrusion that mates with a recess. In some embodiments, snap-fastening can be achieved by simply relying on frictional engagement of two structures.
The term “thin strip” in the context of medications is intended to encompass drug delivery vehicles in the form of strips, films, membranes, foils, patches, or sheets. They are shaped such that one dimension, e.g., the thickness or z-dimension, is substantially thinner than at least one other dimension, e.g., the width or length (the x-dimension or y-dimension), or both other dimensions. The thin strip has width and length dimensions that are significantly larger than its thickness dimension. For example, the width and length can each be at least ten times the thickness dimension, or preferably at least one-hundred times the thickness dimension. Typically, the z-dimension is about 0.01 to about 100 micrometers thick, while the surface area defined by the width and length, e.g. the x-y surface, of the thin strip ranges from about 1 to about 20 cm2. Thin strip medications can be orally dissolving medications but are not limited thereto.
Thin strips (e.g., orally dissolving thin strips) can be advantageous for such individuals because the drug can be applied under the tongue (sublingually) and need not be swallowed.
The terms “neurological condition,” or “neurological disorder,” or “neurological disease” are used interchangeably herein, unless indicated otherwise, and intended to encompass pathologies of the brain, spinal cord, nerves or neuromuscular systems, generally, including but not limited to Parkinson's Disease, ALS, Alzheimer's disease, Bell's palsy, muscular dystrophy, multiple sclerosis and epilepsy.
In certain embodiments, the devices and methods of the disclosure can be used to assist subjects afflicted such neurological conditions. For example, Parkinson's disease is characterized by a lack of dopamine, a signaling molecule in the brain, which can cause afflicted individuals to experience tremors, stiffness, and slowness. A typical approach for treating these symptoms is to administer a dopamine precursor (e.g., levodopa) that can cross the blood-brain barrier more readily than dopamine. Inside the brain, the dopamine precursor is converted into dopamine, thereby easing motor problems.
However, with long-term use the beneficial effects of levodopa or similar dopamine precursor can wear off before a new dose can be taken. The period when the medication has a positive effect on Parkinson's symptoms is called “on-time.” Once the medication stops working, a so-called “off-episode” occurs where symptoms recur. Off-episodes are particularly problematic with prolonged use of levodopa because the body's ability to convert levodopa into dopamine decreases, lowering the medication's efficacy.
The term “off-episode” or variations thereof (e.g., “off condition”) is intended to encompass end-of-dose wearing “off” (including early morning “off”), partial/delayed/No-ON and unpredictable “off” situations where the subject is not responding to a Parkinson's medication).
Apomorphine is an agent known as being useful in the treatment of “OFF” episodes associated with Parkinson's disease. Sunovion Pharmaceuticals has recently developed a sublingual (under the tongue) formulation of apomorphine (APL-130277). Sublingual administration is particularly useful because Parkinson's patients often also exhibit difficulties in swallowing pills.
Thus, the present disclosures can provide devices and methods to assist subjects afflicted with neurological conditions, such as Parkinson's disease, who wish to take apomorphine during their off-episodes. The present disclosure can provide child-resistant devices and methods for administering apomorphine and other medicines to Parkinson's subject who may also have limited fine motor skills.
One method of treating a subject afflicted with a neurological condition, such as Parkinson's disease, can comprise the steps of providing at least one sealed pouch containing a medication, folding a tray around the pouch such it supports the pouch, placing the tray and supported pouch inside a container such that the tray is engaged by the container in a manner that impedes removal of the tray, securing the container with a cap configured to close the opening of the container, allowing the subject to remove the cap and obtain an individual pouch by reaching into the container and pulling the pouch from its supporting tray and further permitting the subject to open the pouch and administer to themselves the medication.
The method can further be useful when the cap is a child-resistant cap and the method further comprises releasing the interlocking engagement of the cap and container. The method can be especially useful when the subject is experiencing an off-episode associated with Parkinson's disease.
The medication can comprise a thin strip medication within the pouch, which can be opened by pulling on opposing tabs of the pouch to separate the pouch into at least sheet elements and allow the subject to access the thin strip medication deployed between the sheet elements. In certain embodiments, the medication can comprise apomorphine, especially apomorphine that is formulated for sublingual release, such that the subject can place the thin strip apomorphine-containing medication under their tongue.
In certain embodiments, the subject may wish to drink and swallow water to help the medication dissolve. Once an individual pouch is removed from the container, a wing tab (described in more detail below) can be held in each hand between the thumb and finger. The wing tabs can be gently pulled apart to open the pouch. Then the sublingual thin strip medication (e.g., a film) can be extracted from the pouch. The film can be placed close to the base of the tongue. The subject should try to avoid chewing, or swallowing the film or saliva. Typically, the film will dissolve in about 2 minutes.
The device 10 further comprises a cap 16 to provide closure of the container 12. The cap 16 and container 12 preferably form a child-resistant closure, e.g., a “quarter-turn” releasable engagement, a “push down and turn” releasable engagement or a “squeeze and turn” releasable engagement. In a “quarter-turn” closure, the cap must be twisted approximately a quarter turn before it can be lifted off. In a “push down and turn” child-resistant closure, the cap is biased such that a down force must be applied to engage threads on outer rim of the container to unscrew the cap from the container. Typically, only a quarter turn is necessary to separate the cap from the container. In “squeeze and turn” closures, the sides of the cap can be pushed in, typically to create clearance between pegs inside the cap and pegs on the outside of the container to be able to twist it open. Although “push down and turn” and “squeeze and turn” caps are often preferable because of their simplicity and common acceptance, it should be clear that any one of a wide variety of child-resistant locking mechanisms can be employed to provide closure of the container. For further descriptions of various child-resistant caps, see “Standard Classification of Child-Resistant Packages,” ASTM Standard D3475-18, (available from the ASTM website) herein incorporated by reference in its entirety.
Generally speaking, pouches for use in the present disclosure can comprise a first sheet layer and a second sheet layer. The first sheet layer can be overlaid on top of the second sheet layer. The first layer can be coextensive with the second layer so that the first layer and the second layer share a common outer perimeter. Some portions of the first layer can be sealed or joined with corresponding portions of the second layer to define one or more pouch seal zones. Some portions of the first layer can remain separate, unsealed, or not joined with the second layer to define one or more unsealed zones. The pouch seal zone can enclose an unsealed pouch zone in which a thin strip medication can be placed. The pouch seal zone thus protects the thin strip medication from exposure.
The pouch can further comprise one or more tabs in a header zone. In some examples, the first sheet layer and the second sheet layer can be sealed together at a first area to create a first tab, and sealed together at a second area to create a second tab. The first tab and the second tab can be separated from the pouch seal zone by an unsealed portion of the pouch. The unsealed portion of the pouch can extend from a first edge of the pouch to a second edge of the pouch opposite the first edge. The first tab and the second tab can be separated by an edge of the pouch that defines a void between the first tab and the second tab.
In some examples, the pouch comprises a first tab-cut on a first side of the pouch (for example, the front of the pouch) and a second tab-cut on the opposite side of the pouch (for example, the back of the pouch). The first tab-cut is a cut through the first layer of the pouch that does not reach the second layer of the pouch. The second tab-cut is a cut through the second layer of the pouch that does not reach the first layer. In some examples the first tab-cut and the second tab-cut do not overlap.
In some examples, the first tab-cut begins at a first edge of the pouch and ends at an edge of the pouch defining the void between the first tab and the second tab. In some examples, the second tab-cut begins at a second edge of the pouch opposite the first edge of the pouch, and ends at the edge of the pouch defining the void between the first tab and the second tab. In some examples, the first tab-cut does not intersect the second tab-cut. In some examples, the first tab-cut and the second tab-cut are both located in the unsealed portion of the pouch. In some examples, the first tab-cut is parallel to a first edge of the pouch seal zone and the second tab-cut is parallel to a second edge of the pouch seal zone. In some examples, the first tab-cut is not parallel to the second tab-cut.
As noted above, the first and second tabs can comprise one or more tactile features. The tactile features can be physical features located on a tab that allow the pouch to be easier to open, such as by decreasing the likelihood that a user's fingers will slip or slide on the tab, or by helping the user to identify the location of the tabs and the best location for grasping the pouch during opening. For example, in lieu of the illustrated dimples, the tactile feature can be an aperture, one or more slits, grooves, recesses or a region of increased surface roughness.
Pouch 20 functions by allowing a user to access the enclosed thin strip medication by gripping the first and second tabs, 56 and 58, and then pulling the tabs in opposite directions. The seal is broken when the first sheet layer is peeled apart from the second sheet layer. Pulling the tabs apart causes the first layer to separate from the second layer by breaking the seal between the first layer and the second layer in the pouch seal zone.
In some embodiments, the pouch seal zone has an apex 53 in the shape of a chevron, as shown in
Further details and alternative constructions for pouches that may be used in the present disclosure can be found in WO2017/214428 and US2017/0355504, the disclosures of which are incorporated herein by reference in their entirety.
The thin strip medication can take a variety of forms, depending, for example, on the nature of the medication and the release mechanism. Orally dissolving thin strip medications, for example, can have a soluble film layer, a coating applied on at least one side of the film layer, and an active ingredient that is contained in the coating, the film layer, or both the coating and film layer. The film layer may be soluble in water and/or saliva and/or other aqueous solutions. In other embodiments, the film layer can be hydrophobic.
The thin strip can take any shape that is suitable for oral administration or applicable to mucous membranes of various body parts of a subject. The film strip may be generally rectangular in shape. In one embodiment, the film strip may be generally rectangular in shape having a dimension of about ½ inch by 1 inch. Alternatively, the film strip may be circular with a diameter of about ⅜ inch. In certain embodiments, the thin strip can have a thickness of about 0.01 to 5 mm. In other embodiments, the film layer can have a thickness of about 0.03 to 2 mm or about 0.04 to 1 mm. Such a film strip may be suitable for application to mucous membranes located in other areas of the body besides the mouth.
The thin strip medication, can be constructed to have an acceptable dissolution rate in the oral cavity or on various mucous membranes of a subject. The composition may dissolve in about 1 second to 5 minutes, preferably, in about 1 second to 3 minutes, or more rapidly in about 10 seconds to 60 seconds.
The film layer may be made from a natural or synthetic polymer. In certain embodiments, the polymer is water soluble. In other embodiments, the polymer may be soluble in saliva and/or other aqueous solutions and/or the polymer may be hydrophobic. Preferably, the polymer has good film moldability, produces a soft flexible film and is safe for human consumption. The polymer may be a water-soluble cellulose derivative such as hydroxypropyl cellulose (HPC), methyl cellulose, hydroxypropyl alkylcellulose, carboxymethyl cellulose or the salt of carboxymethyl cellulose. Alternatively, the polymer may comprise an acrylic acid copolymer or its sodium, potassium or ammonium salt. The acrylic acid copolymer or its salt may be combined with methacrylic acid, styrene or vinyl type of ether as a comonomer, poly vinyl alcohol, poly vinyl pyrrolidone, polyalkylene glycol, hydroxy propyl starch, alginic acid or its salt, poly-saccharide or its derivatives such as trangacanth, bum gelatin, collagen, denatured gelatin, and collagen treated with succinic acid or anhydrous phthalic acid. The film layer may be made from pullulan, maltodextrin, pectin, alginates, carrageenan, guar gum, or other gelatins. The film layer can optionally contain additives known in the art.
Non-limiting examples of thin strips can be found, e.g., in WO2009/052421 the disclosure of which is incorporated herein by reference in their entirety.
Further non-limiting examples of thin strips that can be dispensed according to the disclosure include sublingual apomorphine films for the treatment of Parkinson's disease. Such films and other sublingual thin strips may be found in WO2010/144817, WO2012/083269, WO2016/172095, US2012/0195995, US2011/0111011, and US2018/0133146, the disclosures of which are incorporated herein by reference in their entirety.
