|Full Text||AN ORAL DOSAGE DELIVERY VEHICLE COMPRISING AN EDIBLE FILM WITH A UNIFORMLY
The present invention relates to devices and methods for the storage and dispensing
of an edible, thin, water-soluble, rapid dissolve dosage form.
BACKGROUND OF RELATED TECHNOLOGY
Water-soluble thin films have recently become very popular as a form of breath
freshener. These films generally include a breath freshening agent in a polymer film. These
films have a convenient small size which contributes to their popularity.
However, such films and their current packaging have several disadvantages. The
films themselves are typically too thin to support other active ingredients, such as a
pharmaceutical active. In addition, the packaging does not provide an effective air/moisture
barrier. The result is a film that frequently dries out, becoming too brittle for use.
Furthermore, when the films are placed in the packaging, they are usually stacked, and
frequently adhere to an adjacent film. Therefore, a person attempting to remove a single
film from the packaging may inadvertently remove two or more.
It is desirable to provide a film and packaging that includes a barrier to moisture, air,
and light, which can interfere with the quality of the film product and the active ingredients
contained within the film. Ideally, this film will be capable of supporting not only a breath
freshener as the active, but also pharmaceutical products. It is further desirable to provide a
method of dispensing the films, wherein only the desired number of films may be removed
at a time.
SUMMARY OF THE INVENTION
The present invention provides an oral dosage delivery vehicle including an edible
film having a sheet-like construction, wherein the film comprises dosage units releasably
joined by one or more weakened sections, which permit said dosage units to be detached
from the film. Desirably the weakened sections include a perforated or scored configuration
that may be cut into the film. More desirably, the individual dosage units are uniform in
their composition and include a uniformly distributed active ingredient, such as a drug,
cosmetic, or bioactive agent and the like.
The present invention also provides a package for the storage and dispensing of an
edible sheet-like rapid dissolve dosage form, such as a thin film. The invention includes a
pouch into which a sheet-like dosage form has been placed. The pouch includes top and
bottom layers that are sealed at the edges leaving a space between them for storing the
sheet-like dosage form. The pouch may also include a means for resealing to prevent
additional introduction of light, moisture and/or air. Such resealing means may include
adhesive coatings, mechanical closures, such as those found on resealable plastic bags and
other similar resealing means.
While a variety of film-forming techniques may be used to produce the rapid
dissolving sheet-like dosage forms of the present invention, the present invention also
includes a unique method of producing the edible dosage forms such that uniform
distribution of the compositional components are evenly distributed throughout the film.
This process is described in detail in co-pending U.S. Patent Application No. 10/074,272,
entitled "Thin Film with Non-Self-Aggregating Uniform Heterogeneity and Drug Delivery
Systems Made Therefrom", the subject matter of which is herein incorporated by its
entirety. The process provides dosage forms that consistently include substantially the same
amount of me active ingredient and may include a wide variety of active ingredients,
including pharmaceutical actives.
A further aspect of the present invention provides a method of storing an edible
sheet-like rapid dissolve dosage form. The method includes first preparinga shcet-like
dosage form that includes one or more unit doses of an active ingredient. The sheet may be
separated by weakened sections between individual units or segments, desirably of
substantially equal area, which represent individual dosage units or a predetermined fraction
of a dosage unit. The sheet is placed into a pouch that has top and bottom layers, which
desirably include a barrier layer. The top and bottom layers are sealed at the edges, which
may be through the use of an adhesive, desirably, one that is heat sealable, pressure-
sensitive or which forms a bond at room temperature.
A still further aspect of the present invention provides a method of dispensing a
sheet-like dosage form. First, a sheet-like dosage form that includes one or more doses of
an active ingredient is prepared. Then the dosage form may be separated at weakened
sections therein to form individual segments or units, desirably of substantially equal area,
representing either an individual dosage unit or a fraction thereof, as described above. The
sheet is placed in a pouch having top and bottom layers that may include a barrier material.
The pouch is sealed at the edges. The dosage form is dispensed by opening a portion of the
pouch, desirably a portion of the edge, then separating one or more sections of the dosage
form from the sheet along the weakened sections, and removing the separated dosage unit(s)V
from the pouch. The pouch may then be resealed. \/ACCOMPANYING

DETAILED DESCRIPTION OF THE INVENTION
The present invention includes a "sheet-like" dosage form or a film. For the
purposes of this invention the term "sheet-like" dosage form, "sheet," and film are meant to
include a water soluble delivery system having a thickness of less than about 15mils. The
sheet-like dosage forms are desirably edible and contain an active ingredient.
The sheets or films 5 of the water-soluble rapid dissolve dosage forms, which may
include one or more dosage forms 1, may include weakened sections, as shown in FIG. 1-3.
The weakened section is designed such that application of a bending force thereat breaks
apart adjacent units from each other. The weakened sections 2 in the sheet may form
straight lines in either a vertical direction or a horizontal direction, or combinations of both,
although lines which are not straight may also be used. The weakened sections will divide
the sheet into segments that represent individual doses of an active. The segments may be
in a variety of different shapes and sizes including square, rectangle, triangle, trapezoid,
circle, ellipse, etc. Desirably, the lines will combine to provide sections of substantially
equal area. Each section will represent either an individual dosage form or a predetermined
fraction of a dosage form. For example, a child dose may be one-half of an adult dose for a
particular active, or where a large film is required for a particular dose, the film may be
divided to provide ease of administration. For example, in Figure 2, which shows a sheet
perforated into two sections, each section may be a dosage unit, or the entire sheet may be a
single dosage unit.
The weakened sections themselves may take on a variety of different configurations,
as shown in FIGS. 11-13. In general, a weakened section of the sheet is a location of the
sheet that has been altered to permit separation of sections of the film. Desirably, the
weakened sections are formed so that the individual dosage units are of substantially
identical dimensions. Where the dosage form includes an active, there is uniformity among
dosage units that have been separated, desirably where there is less than 10% variance
among the individual dosage units both before and after separation. The weakened sections
may be in any configuration that permits one section of the film to be separated from the
remaining film. Examples of weakened sections include perforations or scored areas that
form voids 30 in the material, as in FIG 11. As shown in FIG 12 and FIG 13, the voids 30a
and 30b, respectively, may either completely or partially penetrate the film.
Other examples of weakened sections may be used when uniformity of film size is
not an issue, including where the dosage form does not incorporate a drug active. Examples
include narrower sections 32 of the film 5, as shown in FIG. 14, and areas that have less
thickness 34 than the surrounding film, as shown in FIG 15. The weakened sections may be
formed by cutting the film, by casting the film into a pre-determined shape, or by casting
the film onto a patterned surface that results specifically selected thinner areas of the film.
The weakened sections, described above, serve as break-points where the film is
intended to be separated into individual dosage units. The film itself is generally flexible to
avoid inadvertent or premature separation and breaking of dosage units. However, the
weakened sections allow the film to be separated at pre-determined segments that will
represent the individual doses. This separation may be by breaking, bending, tearing, or
otherwise detaching the individual segments the film or sheet-like construction. The dosage
forms may include a line formed of an edible ink along the weakened sections. Such a line
serves as, a "safety" indication line to visibly indicate to the user that they have broken off
the appropriate dosage unit. Particularly where a perforated dosage form is used, this will
assure that the user has detached the dosage form at the appropriate location. This may be
accomplished by perforating the film with a serrated knife-like instrument, which may
include edible ink liners that mark the film as it is cut. Other methods of forming the safety
line, such as printing, may be used.
The surface of the film may either be smooth, or altered in a way to increase the
surface area of the film. Where the surface area is altered, it may include voids 42 or holes
as shown in FIG. 18. The voids will be placed in the film in a uniform manner, which does
not affect the uniformity of the distribution of any active that the film may contain. The
effect of the voids is an increase in the surface area of the film, which will speed the
dissolution time of the film when administered, including an increased speed of dissolution
of the film in the mouth. As shown in FIGS. 19-21, the voids may take a variety of
different shapes, and may go either completely through the depth of the material as the
voids 42a of FIG. 19 or partially through as the voids 42b and 42c, of FIGS. 20 - 21,
respectively. The alteration of the surface area of the film will be conducted in such a way
that will maintain the strength of the film, unlike the alteration at the weakened sections.
Ideally, the voids are formed by either cutting the film or by casting the film on a template
to produce a specific pattern.
As shown in FIGS. 16 and 17, the sheet-like dosage form 5 may include a
substantially water-insoluble backing layer 25. While the films 5 may be self-supporting,
the second carrier layer 25 may act as a support layer for the dosage form 5. The carrier
layer 25 may either be continuous, without the inclusion of weakened sections 2 as in FIG.
16, or it may include weakened sections 2a corresponding to the weakened sections 2 of the
film 5 to allow the second layer 25 to separated along with a corresponding section of the
dosage form 5, as shown in FIG 17.
The edible sheet-like dosage forms of the present invention include a water-soluble
polymer. Useful water-soluble polymers for the present invention include cellulosic
materials, gums, proteins, starches, and combinations thereof.
One advantage of the present invention is that dosage units or a portion thereof may
easily be dispensed. For example, a 10 mg dosage unit may itself contain a break-point
section, i.e., a perforated section, to allow the patient to divide the taking of the required 10
mg dose over two different time intervals, or to simply make it easier to ingest at one time.
Examples of cellulosic materials include, without limitation, carboxymethyl
cellulose, hydroxyl methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose
hydroxypropylmethyl cellulose, and combinations thereof.
Examples of water-soluble gums include gum arabic, xanthan gum, tragacanth,
acacia, carageenan, guar gum, locust bean gum, pectin, alginates and combinations thereof.
Examples of other polymeric materials include polyvinyl alcohol, polyacrylic acid,
polyvinyl pyrrolidone, poly(meth)acrylate, poly(meth)copolymers and combinations
Useful starches include gelatinized, modified or unmodified starches. The source of
the starches may vary and include tapioca, rice, corn, potato, wheat and combinations
Useful water-soluble protein polymers gelatin, zein, gluten, soy protein, soy protein
isolate, whey protein, whey protein isolate, casein, levin, collagen and combinations thereof.
Additional water-soluble polymers include dextrin, dextran and combinations
thereof, as well as chitin, chitosin or combinations thereof, and polydextrose.
The sheet-like dosage forms of the present invention further include an active
component selected from cosmetic agents, pharmaceutical agents, bioactive agents,
including antigens, such as ragweed pollen, and combinations thereof. The active
component may be present in any amount effective for the intended treatment. If is
particularly desirable and an advantage of the present invention that the active component
can be included in high loads. For example, the active component may be present in
amounts up to about 60% by weight of the total composition and desirably in amounts of
0.01% to about 50% by weight of total composition.
The active components that may be incorporated into the films of the present
invention include, without limitation, medicaments, flavors, fragrances, enzymes,
preservatives, sweetening agents, colorants, spices, vitamins and combinations thereof.
A wide variety of medicaments and pharmaceutical compositions may be included
in the dosage forms of the present invention. Examples of useful drugs include ace-
inhibitors, antianginal drugs, anti-arrhythmias, anti-asthmatics, anti-cholesterolemics,
analgesics, anesthetics, anti-convulsants, anti-depressants, anti-diabetic agents, anti-diarrhea

The ingredients of inventive compositions A-J were combined by mixing until a
uniform mixture was achieved. Vacuum was then applied over 20 min. starting at 500
mmHg and ending at 660 mmHg until all air was removed from the suspension. The
compositions were then cast onto a silicone coated paper using a 200 micron spiral wound
rod and a K control Coater Model 101 (RK Print Coat Inst. Ltd.). These films were then
dried by applying heat at 90°C to the bottom of the film. No external thermal air currents
were present above the film. The films were dried to less than about 6% by weight water in
about 4 to 6 minutes. The films were flexible, self-supporting and provided a uniform
distribution of the components within the film.
The layers that form the pouch of the present invention may be made of a variety of
different materials and constructions. As shown in FIG. 6, may themselves include one or
more layers that are laminated together with an adhesive. A variety of different materials
may be used for each of the layers. Desirably, the top and bottom layers will each include a
laminate of at least two layers. More desirably, a three-layer laminate will be included. The
three layer laminate will include an outer layer 16, an inner layer 17, and an intermediate
layer 18 that include an adhesive 15 dispersed therebetween.
One effective barrier material is a metal foil, such as aluminum, which provides a
barrier to light, moisture arid air. Depending on the barrier requirements of the film and any
active contained therein, other materials may be selected for the various layers. These
materials may include paper, polyolefins, such as polyethylene or polypropylene, polyester,
hydrolyzed polyvinyl acetate co-polymer and blends thereof.
The layers may also include, where necessary, an anti-static agent, anti-fogging
agent, ultraviolet light absorber, antioxidant, plasticizer, lubricant, nucleating agent,
dispersant, colorant, anti-fungus agent, anti-microbial agents, inorganic filler, and the like.
In. one aspect of the invention, the layers may be laminated together by first
dispersing an adhesive between the layers which may then be co-extruded to form the multi-
layered packaging of the present invention. The adhesive may include polyolefin resins
such as those modified with unsaturated carboxylic acid or a derivative thereof. The
unsaturated carboxylic acid may include, without limitation acrylic acid, methacrylic acid,
maleic acid, fumaric acid, crotonic acid, itaconic acid, citraconic acid and the like, as well
as esters and anhydrides thereof.
FIG 4 shows layers of a pouch containing the sheet-like dosage forms 5. The pouch
includes top 3 and bottom 4 layers, which may each include a multi-layered laminate
material, which is sealed along the perimeter as shown in FIG. 5. This may be
accomplished, for example, by heat sealing or with an adhesive, such as a pressure-sensitive
The resulting pouch may also be resealable along a portion of its perimeter as shown
in FIGS. 7-9 and 9a. As shown in FIG. 7, this is accomplished by providing a portion of the
perimeter with a pressure sensitive adhesive 7 between the top 3 and bottom 4 layers. At
this point along the perimeter, the top and bottom layers may be separated to allow removal
of a dosage form and then resealing. Alternatively, as shown in FIGS. 8 and 9, a portion of
the perimeter may be sealed and resealed by forming a zipper track 8.along the top layer 3
and a corresponding track 9 along the bottom layer 4 of a portion of the pouch. The two
tracks should be formed such that they can engage, forming a seal along a portion of the
perimeter. The track may be engaged by either manual pressure, or by the use of a zipper
10. FIG 9a adds a "tamper resistant" feature to the packaging, where another layer of
material 19 is included which covers the resealable zipper. This may either be attached by
the use of an adhesive to the top 3 and bottom 4 layers, or alternatively may form an
additional layer over the length of the top 3 and bottom 4 layers (not shown). This allows
the pouch to be opened by the consumer by first removing the surrounding layer 19,
desirably at a perforated section 22 to permit access to the resealable opening.
More than one sheet of the dosage form may be included within the pouch. For
example, two or more sheets may be stacked on top of each other. As shown in FIG 10, a
non-water soluble support film 11, such as a layer of polyolefin, also in the form of a sheet,
may be placed between the sheets of water-soluble dosage forms to prevent the dosage 5
forms in the two or more sheets from adhering to each other.
To dispense a dosage form, the pouch is first opened. This is by either by tearing the
pouch open or by separating the top and bottom layers of the pouch. The sheet may either
be removed from, the pouch, or desirably, where the top and bottom layers are separated, the
film is presented apart from the top and bottom pouch layers, which are peeled away, to
provide greater ease in dispensing. In one embodiment, the top and bottom pouch layers are
peeled apart at one end to present the dosage form in an erect or vertical position for easy
handling. Then, the unit sections of the film/dosage form may be separated by tearing along
the weakened or perforated sections to separate a dose, or fraction thereof, from the sheet.
The remainder of the sheet may then be returned to the pouch until a future dose is needed.
While there have been described what are presently believed to be the certain
desirable embodiments of the invention, those skilled in the art will realize that changes and
modifications maybe made thereto without departing from the spirit of the invention, and it
is intended to include all such changes and modifications as fall within the true scope of the
