Definitions
- Pharmaceuticals intended for oral administration are typically provided in solid form as tablets, capsules, pills, lozenges, or granules. Tablets are swallowed whole, chewed in the mouth, or dissolved in the oral cavity. Soft tablets that either are chewed or dissolve in the mouth are often employed in the administration of pharmaceuticals where it is impractical to provide a tablet for swallowing whole. With chewable tablets, the act of chewing helps to break up the tablet particles as the tablet disintegrates and may increase the rate of absorption by the digestive tract. Soft tablets are also advantageous where it is desirable to make an active ingredient available topically in the mouth or throat for local effects and/or systemic absorption. Soft tablets are also utilized to improve drug administration in pediatric and geriatric patients. Soft tablets designed to disintegrate in the mouth prior to swallowing are particularly useful for improving compliance of pediatric patients.

Abstract
The present invention features an orally disintegrating dosage form including from about 5% to about 40%, by weight, of at least one hydrated salt and a pharmaceutically active agent, wherein the at least hydrated salt has a dehydration temperature of from about 20 to about 120° C.
Description
- Pharmaceuticals intended for oral administration are typically provided in solid form as tablets, capsules, pills, lozenges, or granules. Tablets are swallowed whole, chewed in the mouth, or dissolved in the oral cavity. Soft tablets that either are chewed or dissolve in the mouth are often employed in the administration of pharmaceuticals where it is impractical to provide a tablet for swallowing whole. With chewable tablets, the act of chewing helps to break up the tablet particles as the tablet disintegrates and may increase the rate of absorption by the digestive tract. Soft tablets are also advantageous where it is desirable to make an active ingredient available topically in the mouth or throat for local effects and/or systemic absorption. Soft tablets are also utilized to improve drug administration in pediatric and geriatric patients. Soft tablets designed to disintegrate in the mouth prior to swallowing are particularly useful for improving compliance of pediatric patients.

Examples of suitable taste masking coatings are described in U.S. Pat. No. 4,851,226, U.S. Pat. No. 5,075,114, and U.S. Pat. No. 5,489,436. Commercially available taste masked pharmaceutically active agents may also be employed. For example, acetaminophen particles, which are encapsulated with ethylcellulose or other polymers by a coaccervation process, may be used in the present invention. Coaccervation-encapsulated acetaminophen may be purchased commercially from Eurand America, Inc. (Vandalia, Ohio) or from Circa Inc. (Dayton, Ohio).
- The pharmaceutically active agent may be present in pure crystal form or in a granulated form prior to the addition of the taste masking coating. Granulation techniques may be used to improve the flow characteristics or particle size of the pharmaceutically active agents to make it more suitable for compression or subsequent coating. Suitable binders for making the granulation include but are not limited to starch, polyvinylpyrrolidone, polymethacrylates, hydroxypropylmethylcellulose, and hydroxypropylcellulose. The particles including pharmaceutically active agent(s) may be made by cogranulating the pharmaceutically active agent(s) with suitable substrate particles via any of the granulation methods known in the art. Examples of such granulation method include, but are not limited to, high sheer wet granulation and fluid bed granulation such as rotary fluid bed granulation, the details of which are disclosed in, “The Theory and Practice of Industrial Pharmacy, 3rd edition”, Chapter 11, Lachman, Leon et. al, 1986.
- As discussed above, one advantage of the orally disintegrating dosage form/portion described herein is the ability to incorporate modified particles containing a pharmaceutically active agent, such as taste-masked particles, coated granules, or coated beads which are typically sensitive to compression forces during manufacture. Traditional tablet compression can subject coated particles to forces, which can compromise the function of the coating (e.g., modify taste-masking or modified release properties). In one embodiment the orally disintegrating form of this invention incorporates gel-coated liquid filled beads, which may contain a flavorant, an active ingredient or mixtures thereof. In one embodiment the gel-filled beads are coated with materials that include, but not limited to, hydrocolloids (such as acacia, alginates, agar, guar gum, locust bean, carrageenan, carboxymethylcellulose, tara, gum arabic, tragacanth, pectin, xanthan, gellan, gelatin, maltodextrin, galactomannan, pusstulan, laminarin, scleroglucan, inulin, whelan, rhamsan, zooglan, methylan, chitin, cyclodextrin, chitosan, polyvinyl pyrrolidone, cellulosics, sucrose, starches, and the like; and derivatives and mixtures thereof) and a plasticizer (such as propylene glycol, glycerin or mixtures thereof). Since, in one embodiment, the dosage form disclosed herein does not undergo a compression step, the gel-coated liquid filled beads are less likely break.
- In one embodiment, the orally disintegrative dosage form/portion incorporates modified release coated particles (i.e., particles containing at least one pharmaceutically active agent that convey modified release properties of such agent). As used herein, “modified release” shall apply to the altered release or dissolution of the active agent in a dissolution medium, such as gastrointestinal fluids. Types of modified release include, but are not limited to, extended release or delayed release. In general, modified release dosage forms are formulated to make the active agents(s) available over an extended period of time after ingestion, which thereby allows for a reduction in dosing frequency compared to the dosing of the same active agent(s) in a conventional dosage form. Modified release dosage forms also permit the use of active agent combinations wherein the duration of one active ingredient may differ from the duration of another active ingredient. In one embodiment the dosage form contains one pharmaceutically active agent that is released in an immediate release manner and an additional active agent or a second portion of the same active agent as the first that is modified release.
- In one embodiment the pharmaceutically active agent is coated with a combination of a water insoluble film forming polymer (such as but not limited to cellulose acetate or ethylcellulose) and a water soluble polymer (such as but not limited to povidone, polymethacrylic co-polymers such as those sold under the tradename Eudragit E-100 from Rohm America, and hydroxypropylcellulose). In this embodiment, the ratio of water insoluble film forming polymer to water soluble polymer is from about 50 to about 95 percent of water insoluble polymer and from about 5 to about 50 percent of water soluble polymer, and the weight percent of the coating by weight of the coated taste-masked particle is from about 5 percent to about 40 percent.
- In one embodiment one or more active ingredients or a portion of the pharmaceutically active agent may be bound to an ion exchange resin for the purposes of taste-masking the pharmaceutically active agent or delivering the active in a modified release manner.
- In one embodiment, the pharmaceutically active agent is capable of dissolution upon contact with a fluid such as water, stomach acid, intestinal fluid or the like. In one embodiment, the dissolution characteristics of the pharmaceutically active agent within the orally disintegrative dosage form meets USP specifications for immediate release tablets including the pharmaceutically active agent. For example, for acetaminophen tablets, USP 24 specifies that in pH 5.8 phosphate buffer, using USP apparatus 2 (paddles) at 50 rpm, at least 80% of the acetaminophen contained in the dosage form is released therefrom within 30 minutes after dosing, and for ibuprofen tablets, USP 24 specifies that in pH 7.2 phosphate buffer, using USP apparatus 2 (paddles) at 50 rpm, at least 80% of the ibuprofen contained in the dosage form is released therefrom within 60 minutes after dosing. See USP 24, 2000 Version, 19-20 and 856 (1999). In another embodiment, the dissolution characteristics of the pharmaceutically active agent are modified: e.g. controlled, sustained, extended, retarded, prolonged, delayed and the like.
- In one embodiment, the orally disintegrative dosage form further includes one or more effervescent couples. In one embodiment, effervescent couple includes one member from the group consisting of sodium bicarbonate, potassium bicarbonate, calcium carbonate, magnesium carbonate, sodium carbonate and one member selected from the group consisting of citric acid, malic acid, fumaric acid, tartaric acid, phosphoric acid, alginic acid.
- In one embodiment, the combined amount of the effervescent couple(s) in the orally disintegrative dosage form is from about 0.1 to about 20 percent by weight, such as from about 2 to about 10 percent by weight of the total weight of the disintegrative dosage form.
- The orally disintegrative dosage form may include other conventional ingredients, including other fillers, dry binders like polyvinyl pyrrolidone and the like; sweeteners such as aspartame, acesulfame potassium, sucralose, and saccharin; lubricants, such as magnesium stearate, stearic acid, talc, and waxes; preservatives; flavors; disintegrants, antioxidants; acidulants, such as but not limited to citric acid, malic acid, tartaric acid, ascorbic acid, and fumaric acid; surfactants; superdisinegrants; flavor and aroma agents; antioxidants; preservatives; texture enhancers; and coloring agents.
- Examples of suitable sweeteners for use in the dosage form include, but are not limited to, synthetic or natural sugars, sucralose, saccarin, sodium saccarin, aspartame, acesulfame K or acesulfame, potassium acesulfame, thaumatin, glycyrrhizin, dihydrochalcone, alitame, miraculin, monellin, stevside, and mixtures thereof.
- Examples of superdisintegrants include but are not limited to croscarmellose sodium, sodium starch glycolate and cross-linked povidone (crospovidone). In one embodiment the orally disintegrative form/portion comprises up to about 5% by weight of such superdisintegrant.
- Examples of suitable flavor and aroma agents include, but are not limited to, essential oils including distillations, solvent extractions, or cold expressions of chopped flowers, leaves, peel or pulped whole fruit comprising mixtures of alcohols, esters, aldehydes and lactones; essences including either diluted solutions of essential oils, or mixtures of synthetic chemicals blended to match the natural flavour of the fruit (e.g., strawberry, raspberry and black currant); artificial and natural flavours of brews and liquors (e.g., cognac, whisky, rum, gin, sherry, port, and wine); tobacco, coffee, tea, cocoa, and mint; fruit juices including expelled juice from washed, scrubbed fruits such as lemon, orange, and lime; mint; ginger; cinnamon; cacoe/cocoa; vanilla; liquorice; menthol; eucalyptus; aniseeds nuts (e.g., peanuts, coconuts, hazelnuts, chestnuts, walnuts, and colanuts); almonds; raisins; and powder, flour, or vegetable material parts including tobacco plant parts (e.g., the genus Nicotiana in amounts not contributing significantly to a level of therapeutic nicotine).
- Examples of antioxidants include, but are not limited to, tocopherols, ascorbic acid, sodium pyrosulfite, butylhydroxytoluene, butylated hydroxyanisole, edetic acid, and edetate salts. Examples of preservatives include, but are not limited to, citric acid, tartaric acid, lactic acid, malic acid, acetic acid, benzoic acid, and sorbic acid.
- Examples of texture enhancers include, but are not limited to, pectin, polyethylene oxide, and carageenan. In one embodiment, texture enhancers are used at levels of from about 0.1% to about 10% percent by weight.
- In one embodiment the orally disintegrating dosage form/portion meets the criteria for Orally Disintegrating Tablets as defined by the draft Food and Drug Administration guidance, as published in April 2007, incorporated herein by reference. In one embodiment the orally disintegrating dosage form/portion of this invention meets a two-fold definition for orally disintegrating tablets including the following criteria: 1) that the solid dosage form is one which contains medicinal substances and which disintegrates rapidly, usually within a matter of seconds, when placed upon the tongue and 2) be considered a solid oral preparation that disintegrates rapidly in the oral cavity, with an in-vitro disintegration time of approximately 30 seconds or less, when based on the United States Pharmacopeia (USP) disintegration test method for the specific medicinal substance or substances.
- To determine the in-vitro disintegration for the dosage form, the disintegration test for “Uncoated Tablets” according to USP30-NF25 (using water as the immersion fluid) should be used. Briefly, one dosage unit is placed in each of the six tubes of the basket, and water (maintained at 37±2 C) is used as the immersion fluid. The disintegration time is determined by taking the greatest of six measurements of the time period required to completely disintegrate the respective dosage form/portion. In one embodiment, the in-vitro disintegration time of the orally disintegrative dosage form/portion is less than about 30 seconds, such as less than about 15 seconds.
- In the embodiment wherein the orally disintegrative inner portion is combined with an edible outer portion, the in-vitro disintegration time of the outer edible outer portion is at least ten times, such as at least 50 times or at least 100 times longer than the disintegration time of the orally disintegrative portion.
- Hardness is a term used in the art to describe the diametral breaking strength as measured by a Schleuniger Hardness Tester as described in Leiberman et al., Pharmaceutical Dosage Forms—Tablets, Volume 2, 2nd ed., Marcel Dekker Inc., 1990, pp. 213-217, 327-329. In order to perform the hardness test, a single dosage form/portion is placed into the steel chamber within the hardness tester, and the steel piston pushes against the dosage form until it breaks, measuring the force applied as a hardness measurement. In general, 5 dosage forms/portions are tested from any one sample in order to provide a mean hardness value in kiloponds. In one embodiment the dosage form has a hardness of less than 5 kp/cm3, such as less than 2 kp/cm3, such as less than 1.5 kp/cm3.
- An additional test for hardness of an orally disintegrating dosage form/portion of the present invention relies upon a Texture Analyser TA-XT2i that is fitted with a 7 millimeter diameter flat faced probe and setup to measure and report compression force in grams. The probe moves at 0.5 millimeters per second to a depth of penetration of 2 millimeters. The maximum compression force is recorded. In one embodiment, the measured forces recorded for orally disintegrative dosage forms/portions made in accordance with the present invention preferably ranges from approximately 700 grams to about 6000 grams, up to at most 10,000 grams.
- In one embodiment the flowable material (e.g., the powder) is tamped slightly prior to the heating step. As the particle size of the hydrate is decreased following the tamping, less heat is needed to fuse the agglomerate to achieve the same hardness.
- Pharmaceutical dosage forms, such as pills, capsules, tablets and the like, may be packaged in unit product sheets, such as blister packages. In one embodiment, the blister package are comprised of multi-layered sheets of material having pockets for containing the dosage forms. Conventional blister packages include packages having a foil layer through which a user of the package must push the tablet, breaking the foil. U.S. Pat. No. 4,158,411 discusses such a blister package. Blisters having open tops for containing pharmaceutical tablets are formed in a flexible sheet of plastic or aluminum material. An optional paperboard layer having disc-shaped punch-outs covers the open tops of the blisters overlying each dosage form. A foil layer covers the paperboard layer, holding the punch-outs in place. To open the package, the user must collapse the blister and push the tablet through the foil, also removing the punch-outs.
- Another type of blister package provides perforations between separable blister units so that the user can separate an individual dosage from the package prior to opening. U.S. Pat. No. 4,398,634 illustrates a blister package of this type. The blister portions are defined by tear-resistant, substantially planar plastic sheets sealed to one another in seal zones. The seal zones are located around the periphery of each blister unit, forming pockets of unsealed areas which define the blisters, centrally located in the blister unit. Weakened areas in the seal zones allow the user to separate the blisters into individual units by tearing a unit away from the package. Upon separation of the unit, the user tears through the plastic layers, through the blister, to gain access to the dosage form. A slit in the corner of the unit is provided for easy tearing.
- Another type of blister package includes individual units that, upon separation, reveal a tab for opening the blister. U.S. Pat. No. 5,046,618 discloses this type of blister package. The blister package is formed from a sheet of material having blisters formed therein and a substantially planar lidding sheet. This blister package has two rows of blisters, each blister unit separated from an adjacent unit by perforations. Tear strips separate the rows with perforations that run between the tear strips and the blister units. To open the package, a user separates an individual unit from the package with a tear strip still attached to the unit. This tear strip must be removed to access the tab, which comprises an unsealed area on the corner of the blister unit. After the tear strip is removed, the user grabs the corner of the lidding sheet and peels the sheet back to reveal the dosage form. Suitable materials for constructing the blister cavity for use in the invention described herein include, but are not limited to, polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), aluminum, and polychlorotrifluoroethylene (PCTFE).
- There are various production based machines which may be suitable for making blister packaging, including the use of platen sealing such as that made by the Uhlmann Packaging Systems company under model number UPS4 and the use of rotary sealing such as that made by the Bosch Packaging Group company in Minneapolis, Minn., USA. under model number TLT 1400 and the TLT 2800.
- The unit product sheet may be comprised of a sheet having one or a plurality of recesses (such as from about 2 to about 12, such as from about 2 to about 6) containing dosage forms arranged, for example, in rows and columns. The unit product sheet may includes a plurality of unit packages, each unit package incorporating one recess and a sheet overlying that recess. A set of tear lines can be included between the adjacent unit packages so that a user of the package may tear along the tear lines to separate a unit package.
- The recesses of the package and the dosage forms disposed in the recesses may have essentially any shape. For example, the dosage forms may be disk-shaped tablets, oblong capsules, square-shaped pills, hemispheres or truncated cones. Shapes for recesses include circular, oblong, polygonal, triangles or star shapes in the plane of the blister sheet.
- Furthermore, the walls and bottom of the recesses may define a shape in the form of a surface of revolution, about a vertical axis normal to the flange surrounding each of the recesses. For example, the recesses may have a curved, cup-like shape. Where the dosage forms are disc-shaped, they may each have an edge which contacts the walls of the recess in which each dosage form is disposed. The edge and walls define an annular region of contact coaxial with the vertical axis of the recess. The edge of such a disc-shaped dosage form may comprise a bevel, which contacts the walls of the recess. The annular region of contact prevents shifting of the dosage form within the blister and the damage to the dosage form associated with such shifting. The unit product sheet must be substantially deformable to allow for the punch out and removal of the orally disintegrating dosage form without breakage of the dosage form. The shape of the unit product sheet must also be such that the orally disintegrating dosage form can be punched out and removed without breakage of the dosage form. In one embodiment the (obtuse) angle of the bottom face of the blister to the angle of the side wall of the blister is greater than 90° C., e.g. greater than 110° C.
- (b) Manufacture within Unit Product Sheets
- The orally disintegrative dosage form may be made in a variety of methods. In one embodiment, the orally disintegrating dosage form is made by a method comprising the steps of: (a) providing a unit product sheet having at least one recess in a desired shape and volume suitable for containing the resulting orally disintegrating dosage form; (b) introducing into the recess a predetermined amount of a flowable material comprising at least about 5%, by weight, of at least one hydrated salt and a pharmaceutically active agent, wherein said at least one hydrated salt has a dehydration temperature of from about 20 to about 120° C.; (c) optionally, sealing the flowable material within the recess; (d) heating the material in the recess to a temperature above said dehydration temperature for said at least one hydrated salt and for a sufficient period of time to cause the material to fuse into an aggregate, and (e) cooling the aggregate in the recess so that the aggregate solidifies into the orally dissolving dosage form suitable for consumption.
- In one embodiment a lubricant is added to the unit product sheet (e.g., a blister package) prior to the addition of the flowable material. This lubricant may be a liquid or solid, or integrated into the unit product sheet material. Suitable lubricants include but are not limited to solid lubricants such as magnesium stearate, starch, calcium stearate, aluminum stearate, talc, hydrogenated vegetable oil, sodium stearyl fumarate, glyceryl behenate, and stearic acid; or liquid lubricants such as but not limited to simethicone, lecithin, vegetable oil, olive oil, or mineral oil. In certain embodiments the lubricant is added at a percentage by weight of the orally disintegrating dosage form of less than 5 percent, e.g. less than 2 percent, e.g. less than 0.5 percent.
- A flowable material, preferably in the form of a solid such as a powder or particulate agglomerate, is introduced into at least one of the recesses in the unit product sheet. In one embodiment the flowable material can be defined as one with an angle of repose of 20 to 44 degrees. The angle of repose is defined by Terzaghi in “The Theoretical Soil Mechanics in Engineering Practice”, Wiley, New York, 1948, as the angle between the horizontal and slope of a heap of soil (or powder) dropped from some elevation. In the embodiments of this invention it is defined as the constant angle to the horizontal assumed by a cone like pile of material. This pile is built from a point above the horizontal using two flat glass plates separated by at least ½ inch and which allows for overflow.
- The flowable material is preferably introduced into recesses that are provided in product holding tray that can be a blister-type package described above. The materials in each unit are heated to a temperature above the dehydration temperature for the at least one hydrated salt and for a sufficient period of time to cause the material to fuse into an aggregate, and resulting in a unitary dosage form suitable for handling, removal from the recess of the unit product sheet (such as a blister) and ingestion. In one embodiment, the other components remain solid and maintain their physical properties, including hardness (e.g., the temperature of the recess contents during the heating step should be above the dehydration temperature, but below the melting points and the decomposition temperatures of the other ingredients of the dosage form, including the pharmaceutically active agent). The time of heating is dependent on the at least one hydrated salt and the dimensions of the orally disintegrating form or portion, and must be sufficient in conjunction with the temperature to fuse and stabilize the agglomerate form. In certain cases the active ingredient may be temperature sensitive, requiring different minimal heating temperature with a longer heating time.
- Suitable heat sources include a radiant heater, conductive heating, convective heating, radiofrequency heating, sonic heating, microwave heating, or laser. In one embodiment, the temperature and time of cooling are such as to bridge the carbohydrate or carbohydrate granules with the hydrate salt, creating a soldified dosage form. In one embodiment, a portion of the carbohydrate (e.g., carbohydrate granules) dissolves under release of the water from the hydrated salt and then, upon recrystallization, forms bridged crystalline structures at a microscopic level. In one embodiment, the temperature during cooling is about 25° C. to about 0° C., and the time of cooling is about 10 to about 60 seconds. Generally, the higher the temperature during cooling, the longer the cooling time. In one embodiment the cooling takes place at room temperature (25° C.) for greater than 5 minutes.
- (c) Manufacture within an Edible Outer Portion
- The orally disintegrating dosage form may also be incorporated within a separate edible outer portion, such as a hard candy. In one embodiment, the hard candy portion is a sugar glass hard candy formed from by cooling boiled sugar candy. In another embodiment, the hard candy portion is a compressed sugar candy made by compression, with a hardness of at least 15 kiloponds, such as at least 20 kilponds. In one embodiment, an edible outer portion is pre-made prior to the addition of the orally disintegrating dosage form. In one such embodiment, an outer hard candy or compressed candy ring is manufactured as an edible outer portion, the fixed amount of flowable material containing at least one active ingredient is added, and the dosage form is heated for the temperatures and times described above to form an orally disintegrating tablet portion within the dosage form, and subsequently packaged into a blister, pouch or bottle. In one embodiment, the edible outer portion is substantially enclosed in order to hold the material for the heating or fusing step. In these embodiments, substantially enclosed can be achieved by forming a ring, an oval or other shape such as but not limited to a triangle, star, moon, etc. with an internal hollow portion sufficient to hold the material. This form is placed onto a surface in order to hold the material. This surface may be suitable for holding any flat shape including but not limited to plastic, metal, or composite. This may also be achieved within a preformed unit product sheet and may have negative embossing in order to transfer a logo, image or product identification upon heating and fusing of the dosage form. Alternatively, the dosage form may be lasered or printed for aesthetic imaging (shapes, characters, colors, etc.) or identification (product name, dosage, etc.).
- In one embodiment, the outer hard candy form is made using uniplast rolling, roping and subsequent cutting and stamping, as well as depositing into molds. In one embodiment, the hard candy portion contains one or more sugars selected from the group consisting of isomalt, sucrose, dextrose, corn syrup, lactitol, and hydrogenated starch hydrolysates. In one embodiment, the hard candy portion contains at least 50% (such as at least 75%, such as at least 90%) by weight of such sugar(s).
- In one embodiment, the dosage form comprising an edible outer portion and an inner orally disintegrating portion is coated with an immediate release sugar coating or film coating. To produce such a dosage form, the step following the fusing (heating) and subsequent cooling of the dosage form would involve further sugar or film coating in a coating pan.
- In one embodiment the edible outer portion contains a pharmaceutically active agent and the orally disintegrating portion contains the same pharmaceutically active agent. In one embodiment the edible outer portion contains a pharmaceutically active agent and the orally disintegrating dosage form contains a different pharmaceutically active agent. In one embodiment the edible outer portion disintegrates at a rate of at least 10 times greater than the rate of the orally disintegrating dosage form portion, such as at least 20 times greater. In one embodiment, the orally disintegrating portion meets the FDA requirements for Orally Disintegrating Tablets. In one embodiment the orally disintegrating portion contains an upper respiratory pharmaceutically active agent such as pseudoephedrine, dextromethorphan, cetirizine, diphenhydramine, and chlorpheniramine and the edible outer portion contains menthol.
- In one embodiment, the present invention features a method of treating an ailment, the method comprising orally administering the above described dosage form wherein the dosage form includes an amount of the pharmaceutically active agent effective to treat the ailment. Examples of such ailments include, but are not limited to, pain (such as headaches, migraines, sore throat, cramps, back aches and muscle aches), fever, inflammation, upper respiratory disorders (such as cough and congestion), infections (such as bacterial and viral infections), depression, diabetes, obesity, cardiovascular disorders (such as high cholesterol, triglycerides, and blood pressure), gastrointestinal disorders (such as nausea, diarrhea, irritable bowel syndrome and gas), sleep disorders, osteoporosis, and nicotine dependence.
- In one embodiment, the method is for the treatment of an upper respiratory disorder, wherein the pharmaceutically active agent is selected from the group of phenylephrine, cetirizine, loratidine, fexofenadine, diphenhydramine, dextromethorphan, chlorpheniramine, chlophedianol, and pseudoephedrine.
- Specific embodiments of the present invention are illustrated by way of the following examples. This invention is not confined to the specific limitations set forth in these examples.
- Using a Bosch TLT 1400 (rotary thermoforming sealing) blister line machine, a web of aluminum blister forming material is unwound from a roll, and then indexed into the forming station where compressed air and/or a vacuum is used to form cavities in the web at a ⅝ inch flat round cavity with depressions containing the product's tradename as an identifier to produce a thermoformed web.
- The resulting thermoformed web is indexed into a feeder station where the tablet blend formulation described below in Example 2 are deposited into the formed cavities.
- An orally disintegrating immediate release loratidine tablet blend formulation including the ingredients of Table 1 is manufactured as follows:
-

The loratidine and sodium hydrogen phosphate hydrate are added and blended end over end for an additional 3 minutes. The blend is then filled into the pre-formed blister cavities in Example 1.
- Blister forming pins or punches, used to pre-form the blister cavities prior to addition of the flowable material, contain small injection ports which inject approximately about 0.1-5 mg of soy lecithin onto the surface of the blister upon forming the cavity, in order to facilitate ejection of the blend formulation. The formed blister material from Example 1 is then indexed into a seal station where a foil lidding is applied. The lidding material is unwound from a roll and sealed together using heat and mechanical pressure resulting in the product being contained within the cavity. The sealed blister is placed into a convection oven set at 55° C. for 15 minutes
- The sealed web is indexed toward the perforating station. The perforating station uses sharp cutting blades to place perforations through the web resulting in a blister card with an opening feature. Lastly, the web moves to the punch station where individual blister are cut from the web into individual cards containing 6 orally disintegrating forms per card.
- The blister cavity is then cooled at 0° C. for 5 minutes and sealed. The tablets are then removed from the blister cavity as a single dosage unit for ingestion.
- All materials set forth in Table 2 below are manually passed through a 30 mesh screen. One and a half (1.5) kg of the resulting blend are placed in a 4 quart V-Blender and mixed for 5 minutes.
