Description

Pharmaceutical dosage forms and uses thereof

This application is a divisional application of the chinese patent application having application number 201610395483.9 filed on day 2016, 6, 3, entitled "pharmaceutical dosage forms and uses thereof," which claims priority from us provisional patent application having application number 62/170,645 filed on day 2015, 6, 3, and us provisional patent application having application number 62/313,092 filed on day 2016, 3, 24, which is incorporated herein by reference in its entirety.

Technical Field

The present invention relates generally to a pharmaceutical dosage form and controlled release of bioactive agents, diagnostic agents, reagents, cosmetic agents and agricultural/pesticidal agents.

Background

The medicine must be prepared into a medicine dosage form for being sold and used. Conventional pharmaceutical dosage forms are typically made by mixing the pharmaceutically active ingredient with inactive ingredients (excipients) and other non-reusable materials such as capsule shells. Pharmaceutical dosage forms are classified as liquid pharmaceutical dosage forms (e.g., solutions, syrups, elixirs, suspensions and emulsions), solid pharmaceutical dosage forms (e.g., tablets, capsules, caplets and gel caps), and semisolid pharmaceutical dosage forms (e.g., ointments and suppositories), with solid pharmaceutical dosage forms being most advantageous for oral drug systems.

Tablets are the most commonly used solid pharmaceutical dosage form, which is advantageous in terms of manufacturing, packaging and shipping, and is easier to identify and swallow. After being administered to an organism, the tablet interacts with the body to exert a medicinal effect. The pharmaceutically active ingredient must be released before the tablet is absorbed into the blood circulation. The pharmaceutical composition is then dispersed, or dissolved, in the body by body fluids and tissues. In this process of drug absorption, deposition, metabolism and elimination, the pharmaceutical dosage form plays a crucial role in determining the drug release profile and bioavailability. Accordingly, there is a continuing need to develop a drug dosage form that provides a controlled delivery system that provides desirable levels of drug in the plasma, reduces side effects, and improves patient compliance with the drug.

Detailed Description

In the foregoing summary and detailed description of the invention and in the following claims and accompanying drawings, reference has been made to specific features (including method steps) of the invention. It is to be understood that the disclosure of the invention in this specification includes all possible combinations of these specific features. For example, where a particular aspect or embodiment of the invention or a particular claim discloses a particular feature, that feature can, to the extent possible, also be used in combination with other features and embodiments of the invention, or the invention as a whole.

The use of "including" and its equivalents herein means that additional components, ingredients, steps, etc., are optionally present. For example, an article "comprising" components A, B and C can consist of (i.e., consist only of) A, B and C, or contain more components in addition to A, B and C.

When reference is made to a method comprising two or more specific steps, the specific steps may be performed in any order or simultaneously (unless the context clearly excludes this possibility), and the method may comprise one or more further steps, which may be performed before, during or after any of the specific steps (unless the context clearly excludes this possibility).

When a range of values is recited, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range, and any other stated or intervening value in that stated range, is encompassed within the disclosure, excluding the limits expressly stated in that range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure.

A "at least" followed by a number indicates a range with the number as the lower limit (which range may or may not have an upper limit, depending on the variable being defined). For example, "at least 1" indicates 1 or greater than 1. A number following "at most" indicates a range with the number of the change as the upper limit (depending on the variable being defined, the range may have a lower limit of 1 or 0, or no lower limit). For example, "at most 4" indicates 4 or less than 4, and "at most 40%" indicates 40% or less than 40%. In the present disclosure, when a range is defined as "(first number) to (second number)" or "(first number) - (second number)", it means that the lower limit of the range is the first number and the upper limit is the second number. For example, 2 to 10 millimeters indicates that the lower limit of a range is 2 millimeters and the upper limit is 10 millimeters.

For purposes of simplicity of explanation, the reference numbers are repeated among the different figures to indicate corresponding or analogous elements, where appropriate. In addition, this description provides numerous specific details for a thorough understanding of the embodiments described herein. However, the embodiments described herein may be practiced without these details. In other instances, methods, procedures, and components have not been disclosed in detail so as not to obscure the description of the relevant functionality. Furthermore, the description herein should not be read as limiting the scope of the embodiments described herein. It should be understood that the description and characterization of the embodiments set forth in this disclosure are not mutually exclusive, unless otherwise specified.

Controlled release pharmaceutical dosage form

As shown in FIG. 1A, conventional solid pharmaceutical dosage forms, such as flat tablets, are made by dissolving or embedding a pharmaceutically active ingredient in a matrix. Existing conventional solid pharmaceutical dosage forms exhibit a first order drug release profile (fig. 1B) in which the drug level in plasma increases rapidly after administration and then decreases exponentially (fig. 1C). The disadvantage of this release profile is the reduced therapeutic efficacy due to reduced drug levels or the toxicity associated with high drug concentrations. This drug release is detrimental to the balance of drug levels in the plasma. The present invention relates to an adjustable or controlled release oral delivery system having the advantages of increased patient compliance, selective pharmacological effects, reduced side effects, and reduced frequency of drug delivery as compared to conventional systems. The controlled release prolongs the administration process and can maintain the blood concentration in the treatment period. For example, a delivery system exhibiting a zero order release profile (fig. 1D) allows a constant dose of drug to be released continuously over an extended period, resulting in a uniform and constant delivery process. Thus, zero order release profiles may also be required for antibiotic delivery, hypertension treatment, pain management, antidepressant delivery, and many other situations requiring constant plasma drug levels.

The present disclosure thus provides a stable oral solid pharmaceutical dosage form. In some embodiments, a pharmaceutical dosage form includes a matrix, at least one compartment formed within the matrix, and a drug matrix loaded in the compartment. Pharmaceutical dosage forms are designed to allow the release of the pharmaceutically active ingredient in a controlled manner from a pharmaceutical matrix.

A. Base body

As used herein, "matrix" refers to a structure that contains or has embedded therein a drug matrix. The matrix of the pharmaceutical dosage form may be of any size or shape suitable for oral administration. In some embodiments, the matrix is a flat circular tablet having a diameter of 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, or 12 mm. In some embodiments, the matrix is an oval tablet having a size of about a mm x b mm, wherein a is between 5 and 15 and b is between 2 and 10. In some embodiments, the substrate is capsule-shaped.

In some embodiments, the matrix is made of hydrophilic polymers (e.g., Hydroxypropylmethylcellulose (HPMC) and poly (ethylene oxide) (PEO)), hydrophobic polymers (e.g., Ethylcellulose (EC)), swellable polymers, non-swelling polymers, porous polymers, non-porous polymers, erodable polymers, or non-erodable polymers.

In some embodiments, the pharmaceutical agent has a monomer matrix. In some embodiments, the substrate is constructed of multiple components, each component being made of the same or different materials.

In some embodiments, the matrix is made of a thermoplastic material. By "thermoplastic material" is meant herein a material that can be deformed by heat or pressure. In some embodiments, for example, the thermoplastic material may be a hydrophilic gel material that releases the drug matrix by diffusion; or hydrophobic material, and the drug matrix is released by diffusion out through the pores of the matrix. Polymers, in particular cellulose ethers, cellulose esters and/or acrylic resins, can be used as hydrophilic thermoplastic materials. Ethylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, hydroxymethylcellulose, poly (meth) acrylic acid and/or their derivatives, such as salts, amides or esters, can also be used as thermoplastic materials. Hydrophobic materials which are physiologically recognized and known to the person skilled in the art, for example mono-or diglycerides of C12-C30 fatty acids and/or C12-C30 fatty alcohols and/or waxes or mixtures thereof, can be used as thermoplastic materials. The matrix may also be made of hydrophobic materials, such as hydrophobic polymers, waxes, fats, long chain fatty acids, fatty alcohols or the corresponding esters or ethers or mixtures thereof.

In some embodiments, the thermoformable material is selected from the group consisting of polyvinyl caprolactam polyvinyl acetate-polyethylene glycol graft copolymer 57/30/13, polyvinylpyrrolidone-polyvinyl acetate copolymer (PVP-VA)60/40, polyvinylpyrrolidone (PVP), polyvinyl acetate ester (PVAc) and polyvinylpyrrolidone (PVP) copolymer 80/20, polyethylene glycol-polyvinyl alcohol graft copolymer 25/75, Kollicoat IR-polyvinyl alcohol copolymer 60/40, polyvinyl alcohol (PVA or PV-OH), polyvinyl acetate ester (PVAc), polybutylmethacrylate-poly 2-dimethylaminoethyl methacrylate-polymethylmethacrylate copolymer 1: 2: 1, a polymethacrylic acid dimethylamino-polymethacrylate copolymer, a polyethylacrylate-polymethylmethacrylate-polytrimethylethylvinylchloride copolymer, a polymethyl acrylate-polymethylmethacrylate-polyacrylic acid copolymer 7: 3: 1, polymethacrylic acid-polymethylmethacrylate copolymer 1: 2, poly (methacrylic acid) -poly (ethyl acrylate) copolymer 1:1, poly (methacrylic acid) -poly (methyl methacrylate) copolymer 1: polyethylene oxide (PEO), polyethylene glycol (PEG), hyperbranched polyesters, hydroxypropylmethylcellulose phthalate, hydroxypropylmethylcellulose or Hydroxypropylmethylcellulose (HMPC), hydroxypropylmethylcellulose succinate or hydroxypropylmethylcellulose acetate succinate (HPMCAS), polylactide-polylactic acid copolymer (PLGA), carbomer, polyethylene-polyvinyl acetate copolymer, ethylene-vinyl acetate copolymer, Polyethylene (PE) and Polycaprolactone (PCL), Hydroxypropylcellulose (HPC), polyoxyethylene 40 hydrogenated castor oil, Methylcellulose (MC), Ethylcellulose (EC), poloxamer, hydroxypropylmethylcellulose phthalate (HPMCP), poloxamer, hydrogenated castor oil, glyceryl palmitostearate, carnauba wax, polylactic acid (PLA), polyglycolic acid (PGA), Cellulose Acetate Butyrate (CAB), colloidal silica, titanium oxide, sucrose, glucose, polyvinyl acetate phthalate (PVAP), and combinations thereof.

In some embodiments, the thermoformable material allows the pharmaceutical dosage form to be made by additive methods, such as Fused Deposition Modeling (FDM). In some embodiments, the pharmaceutical dosage form may be manufactured by extruding the thermoformable material through a 3D printer. Typically, the thermoformable material is melted in a 3D printer and then extruded to form the matrix. In some embodiments, suitable extruders include, but are not limited to, single or twin screw extruders, with the extruder temperature set between 50 ℃ and 180 ℃ and between 80 ℃ and 140 ℃. In general, the extrusion process can be carried out between 10 ℃ and 40 ℃ above the glass transition (Tg) temperature of the thermoformable material. Once the 3D printer reaches the appropriate temperature, the thermoformable material may be deposited onto the stereographic printing surface. Control of the shape and size of the substrate and compartment made of thermoformable material may be achieved by programming the printing process of the 3D printer.

In some embodiments, the release profile of the drug matrix can be controlled by the selection of the matrix material. For example, a matrix made of a material of a particular solubility, permeability or erodibility can, upon administration, open the compartment in a predetermined manner and release the drug matrix at a desired rate. In some embodiments, the matrix is made of an erodable or soluble substance, and the pharmaceutically active ingredient (API) is embedded or dissolved in the matrix. The active pharmaceutical ingredient is released as the matrix erodes or dissolves.

The release of the drug matrix or the pharmaceutically active ingredient can also be controlled by adjusting the thickness of the matrix. For example, the matrix forming the compartments is made of a soluble substance. The opening of the compartment and thus the release of the drug can be controlled by adjusting the walls of the matrix surrounding the compartment. For example, the thicker the walls of the compartment, the later the opening of the compartment, the later the release of the drug.

B. Compartment

In certain embodiments, the pharmaceutical dosage forms disclosed herein comprise at least one compartment in the matrix. By "compartment" herein is meant a space, portion or room marked or separated by a substrate. A compartment may be either closed or open (i.e. with holes). One compartment may be of any geometry that facilitates loading of the drug matrix. In some embodiments, the compartment shape may be pie-shaped, pyramid-shaped, column-shaped, or cone-shaped.

In some embodiments, the specially designed compartment shape is such that it can release the drug matrix at a specific rate. In some embodiments, the compartment shape can be wedge-like, triangular prism-like, pie-like, pyramid-like, column-like, cube-like, oval-like, or cone-like.

In certain embodiments, the inclusion of a compartment in the pharmaceutical dosage form may increase residence in the gastrointestinal tract. Fig. 2A illustrates an exemplary pharmaceutical dosage form having a matrix forming a compartment containing a drug matrix. Referring to fig. 2A, a pharmaceutical dosage form 100 has a base 101 forming a compartment 102. The drug matrix 103 is contained in the compartment 102 by connecting the inner walls of the compartment 102. The compartment 102 may provide buoyancy to the drug dosage form 100 to extend its residence time in the stomach or in a liquid or acidic environment. The solubility of the matrix material determines the lifetime of the pharmaceutical dosage form and a sustained release of the API as shown in figure 2B can be achieved accordingly.

Figure 3 illustrates exemplary drug dosage forms that increase gastrointestinal residence time. Referring to fig. 3, a compartment 202 of a drug dosage form 200 includes a second drug dosage form 203 (e.g., a tablet) that is freely movable therein. The gastrointestinal residence time of the pharmaceutical dosage form is limited. The floating system allows the system to stay in the stomach and continuously release the drug in the upper gastrointestinal tract to maximize absorption in the small intestine.

In one embodiment, the compartments of the drug dosage form have different geometries. Fig. 4A shows an exemplary pharmaceutical dosage form having a matrix containing pie-shaped compartments within the matrix, the areas of the dissolution boundaries of the pie-shaped compartments increasing inwardly from adjacent the outer side of the pharmaceutical dosage form such that the pie-shaped compartments are generally fan-shaped when viewed from above and downward in the direction of fig. 4A. Fig. 4B illustrates an exemplary pharmaceutical dosage form having a matrix containing a plurality of compartments with different opening sizes therein, the compartments being generally prismoid-shaped. Fig. 4C illustrates an exemplary pharmaceutical dosage form having compartments at different angles within the matrix. Fig. 4D illustrates an exemplary drug dosage form having pie-shaped compartments with different radii contained within a matrix.

The shape of the compartments may be used to control the release profile of the pharmaceutical dosage form. For example, r.a. lipper and w.i. higuichi describe an application system that can achieve a zero order release profile as shown in fig. 5. Figure 5 shows a cross-sectional view of an application system with a pie-shaped compartment. The compartment may communicate with the outside through a small opening. The compartment is loaded with the drug matrix and the drug matrix upon dissolution will release the API to the outside through a small opening. The dissolution rate of the drug matrix is positively correlated with the area of the dissolution boundary of the drug matrix (the interface between the drug matrix and the compartment space). On the other hand, the dissolution rate of the API in the environment is inversely related to the diffusion path length λ. Thus, as the drug matrix dissolves, the area of the dissolution boundary increases, and the rate of dissolution of the drug matrix also increases. On the other hand, the diffusion path length also increases as the drug matrix dissolves. The API released in the compartment needs to be transferred a longer distance to diffuse out of the drug dosage form. It is assumed that the pharmaceutical dosage form may be designed to comply with zero order release kinetics (R.A. Lipper and W.I.Higuchi (1977) analysis of the theoretical behaviour of a pseudo-zero order drug delivery system, J.Pharmaol.Sci.66 (2): 163-4; D.Brooke and R.J.Washkuhn (1977) zero order drug delivery system: theory and preliminary tests, J.Pharmaol.66 (2) 159-.

In some embodiments, the drug matrix further comprises a medium. The medium may be associated with an API, for example, the substrate may be in physical contact with the API. In some embodiments, the API may be embedded in the substrate. In some embodiments, the API may be dispersed in the substrate.

In some embodiments, the medium includes a water-soluble excipient. The water soluble excipient is selected from the group consisting of: cocoa butter, polyethylene glycol (PEG), sucrose, glucose, galactose, fructose, xyloselactose, maltose, trehalose, sorbitol, mannitol, maltodextrin, raffinose, stachyose, fructooligosaccharides or combinations thereof. In some embodiments, the substrate further comprises a plasticizer.

In certain embodiments, the media has a higher erosion/dissolution rate than the API.

The drug matrix may be loaded into the compartment in any suitable shape or size.

In some embodiments, the drug matrix is operably linked to the compartment by a covalent bond, a non-covalent bond, or a linker. Thus, the drug matrix and the matrix may be separately prepared and then linked by covalent or non-covalent bonds. In some embodiments, the pharmaceutical dosage form produces the drug matrix and the matrix at one time by a method of 3D printing.

In some embodiments, the drug matrix is shaped into a tablet, an oval tablet, a pill, or a capsule. In some embodiments, the drug matrix shape and the compartment shape are identical. For example, when the compartment is shaped as a cake, the drug matrix is also shaped as a cake to fill the compartment.

In some embodiments, as shown in fig. 6, the drug matrix is in the form of nanoparticles. The drug matrix is mixed with a solution in which the API is dissolved or dispersed. During subsequent 3D printing of the pharmaceutical dosage form, the solution is atomized/sprayed onto the printed layer. Once the solution containing the drug matrix is air dried, the drug matrix is dispersed within the pharmaceutical dosage form. The nanoparticles have a larger surface area and thus a higher dissolution rate.

The size of the nano-particles is between 1nm and 900nm (preferably 100-800nm, 100-700nm, 100-600nm, 100-500nm, 100-400nm, 100-300nm, 100-200nm, 1nm, 2nm, 3nm, 4nm, 5nm, 6nm, 7nm, 8nm, 9nm, 10nm, 11nm, 12nm, 13nm, 14nm, 15nm, 16nm, 17nm, 18nm, 19nm, 20nm, 100nm, 200nm, 300nm, 400nm, 500nm, 600nm, 700nm, 800nm, 900 nm). The size of the nanoparticles can be controlled by selecting an appropriate synthesis method and/or system. In order to obtain nanoparticles within the desired size range, the synthesis conditions may be suitably controlled or varied to provide, for example, a desired solution concentration or a desired cavity range (for a detailed review, see: Vincenzo Liveri, controlled synthesis of nanoparticles in a micro-heterogeneous system, Springer, 2006).

As shown in fig. 7, in some embodiments, the drug matrix may be in the form of microneedles. The drug matrix in the form of microneedles is typically encapsulated in a housing having a needle-like structure. The microneedles may also be printed with the drug dosage forms or embedded into the drug dosage forms during 3D printing of the drug dosage forms. Microneedles may be composed of saccharides, PLGA polymers, APIs, or combinations thereof. Upon parenteral or enteral administration, the microneedles may help the API enter the circulatory system of the patient.

In some embodiments, the drug matrix may be configured as a network. As shown in FIG. 8A, a drug matrix of a pharmaceutical dosage form is loaded into a compartment within the base. The base of the drug matrix is constructed as a network, for example made of a loose material, the density of which is usually less than the density of the matrix. The frame structure of the tablet is made of a material that dissolves in 1-10 minutes and the base dissolves in 2-60 seconds, preferably in 2, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60 seconds. As shown in fig. 8B, the API may be released within a few seconds after the drug dosage form is applied.

The drug matrix content can be made by using additive methods, such as Fused Deposition Modeling (FDM) methods. In some embodiments, the drug matrix may be made by extruding a mixture of the API and excipient by 3D printing. The API is melted and mixed uniformly with the melted substrate prior to extrusion. Alternatively, the API in solid form (e.g., powder) may also be mixed with or dispersed in the melted substrate prior to extrusion. Typically, the extrusion process is carried out at a temperature between 10 and 40 ℃ above the glass transition temperature of the substrate and close to the melting point of the API. Once the 3D printer reaches the appropriate temperature, the substrate is deposited onto the stereographic printing surface. The shape and size of the drug matrix can be controlled by programming the 3D printing process. In some embodiments, both the drug matrix and the matrix may be manufactured in the same process. In some embodiments, the matrix is manufactured after the drug matrix is manufactured, and the drug matrix is loaded into the compartment during or after the manufacturing process of the matrix.

In some embodiments, the drug matrix is associated with the matrix when the drug matrix is loaded into the compartment, e.g., the drug matrix is embedded or otherwise immobilized in the matrix. In some embodiments, the drug matrix may be separate from the substrate when the drug matrix is loaded into the compartment.

D. Controlled release

The pharmaceutical dosage forms of the present disclosure have different release profiles after oral administration. In some embodiments, the pharmaceutical dosage form has a constant release, pulsed release, delayed release, or nonlinear release profile. In some embodiments, the pharmaceutical dosage form has zero order release kinetics.

In the present disclosure, the release of the drug is measured in an aqueous solution. The aqueous solution includes gastric juice, intestinal juice, body fluid, and aqueous solution containing inorganic or organic compounds. The aqueous solution also includes water.

For a particular field of drug therapy, a suitable release profile would provide a number of benefits. For example, the pulsatile release profile allows for controlled absorption to reduce the peak level/trough level ratio, and for targeted release of the drug matrix to specific regions in the gastrointestinal tract and absorption processes independent of feeding conditions, and thus the profile can be used to improve bias, reduce side effects and improve patient compliance, which are essential for the treatment of ADHD disease. As another example, a loading dose followed by a maintenance dose may be advantageous for treating chronic diseases such as hypertension and diabetes.

Several mechanisms for controlling the release profile using the pharmaceutical dosage forms of the present disclosure have been discussed above. For example, a drug matrix embedded in a matrix can provide a constant amount of drug over a long period of time by adjusting the exposed area of the matrix that is continuously eroded. In addition, the release profile rate of the API can be controlled by the size of the compartment opening and/or the geometry of the compartment.

In some embodiments, the release profile can be controlled by designing a compartment with an aperture that is closed or blocked by a plug. The plug is made of water-soluble, porous or erodible material or pH sensitive material or hydrophobic material and the like which can be dissolved, degraded and structurally changed when the medicament dosage form passes through the gastrointestinal tract. When the dosage form is applied to a subject, the stopper is melted, penetrated or eroded and the drug substance in the compartment is released. The rate of release profile of the drug matrix can be controlled by selecting a plug water-soluble material with appropriate solubility, permeability, and erodibility. Alternatively, for plugs used to block holes on a compartment, the release profile rate of the drug matrix API may be controlled by using a plug of suitable shape and/or size (e.g., a cylinder of suitable length). The release profile can also be controlled by a different number of compartments. Fig. 9 illustrates an exemplary dosage form having a matrix containing a plurality of columnar compartments distributed on either side of the drug dosage form. Each compartment contains a drug matrix. Each compartment has a hole blocked by a cylindrical plug. These plugs have different solubilities. Depending on the size, shape and solubility of the plug, the release of the API may be sustained, continuous, simultaneous, sequential or pulsatile.

Fig. 10A illustrates an exemplary pharmaceutical dosage form having a sequential release profile. Referring to FIG. 10A, the drug dosage form 700 includes three columnar compartments 702-704 within a base 701. Each compartment is loaded with a drug matrix containing the same API. Each compartment has a hole that is blocked by rod-like plug 705-707. These plugs are made of the same material but are of different lengths from each other and therefore the time required to dissolve the plugs to open the compartments to release the drug matrix is also different. As shown in fig. 10C, the shortest plug dissolves first and releases the API from the first compartment. After the API in the first compartment is completely released, the medium length plug dissolves and releases the API from the second compartment. After the API in the second compartment is completely released, the third plug dissolves to release the API from the third compartment. Thus, after the drug matrix in the first compartment is released, the plasma drug level reaches a first peak. When the API released from the first compartment begins to be consumed, the plasma drug level begins to drop (see fig. 10D). The API in the second compartment is released before the plasma drug level falls to a critical level (a parallel line below which the drug is ineffective) and the plasma drug level increases again. When the released API in the second compartment reaches a second peak and begins to be consumed, the plug of the third compartment dissolves to open the compartment. Thus, plasma API levels can be maintained above critical levels for extended periods of time, which is beneficial for the treatment of specific diseases.

Sequential release profiles may be achieved by another exemplary pharmaceutical dosage form. The pharmaceutical dosage form contains several drug matrices encapsulated in a stack as shown in figure 10B. Simultaneous dissolution of the layers may achieve a sustained release of the API to provide a continuous, sustained release of the API as shown in fig. 10C. In some embodiments, the outer layer of the pharmaceutical dosage form dissolves and releases the embedded drug matrix immediately after the pharmaceutical dosage form is applied. But the outer layer blocks the sandwiched layer from communicating with the environment, causing the intermediate layer to be insoluble or dissolve at a very slow rate. In other words, the outer layer generally dissolves prior to the intermediate layer, and thus the pharmaceutically active ingredient contained in the outer layer is generally released prior to the pharmaceutically active ingredient in the intermediate layer. The dissolution of the outer layers exposes the sandwiched layers to accelerate their dissolution, thus achieving a sequential release profile as shown in fig. 10C. In some embodiments, the drug dosage form includes a gas generant composition loaded within the first compartment. In some embodiments, the gas generant composition is selected from the group consisting of: organic acids and carbonates, sulfites, bicarbonates, sodium carbonate, sodium bicarbonate, sodium metabisulfite, calcium carbonate and combinations thereof. The gas generating component releases carbon dioxide or sulfur dioxide gas upon contact with gastric fluids. When the matrix is dissolved, permeated or eroded in the stomach, the gas-generating component will effervesce to generate gas to release the drug matrix as the gas-generating component is exposed to an acidic environment or water permeates into the compartment to initiate the reaction of the acid with the sodium bicarbonate. It should be noted that, the dissolution time of the different layers may be set according to the adjustment of the thickness, dissolution rate, permeability, erosion rate, etc. of each layer of the pharmaceutical dosage form, so that the different layers can be dissolved in a preset time or dissolution profile, thereby enabling the active pharmaceutical ingredient therein to be released in a preset release profile.

The pharmaceutical dosage forms of the present disclosure comprise one or more drug matrices in at least partially delayed release form, wherein the delayed release may be controlled by conventional materials or in a manner well known to those skilled in the art, e.g., by embedding an API in a delayed release matrix/substrate or by using one or more delayed release coatings. By delayed release, the API release can be controlled to be satisfactory for administration twice or once a day, which has advantages for treatments requiring sustained doses of the active ingredient to combat pain.

In some embodiments, the pharmaceutical dosage form may release the active ingredient immediately in the oral cavity. For example, in the oral cavity or sublingual area.

In some embodiments, the pharmaceutical dosage form further comprises conventional auxiliary substances well known to those skilled in the art, preferably glyceryl monostearate, semisynthetic triglyceride derivatives, semisynthetic glycerides, hydrogenated castor oil, glyceryl palmitate, glyceryl behenate, polyvinylpyrrolidone, gelatin, magnesium stearate, stearic acid, sodium stearate, talc, sodium benzoate, boric acid, and colloidal silicon dioxide, fatty acids, substituted triglycerides, glycerides, polyoxyalkylene glycols and derivatives thereof.

Preparation of pharmaceutical dosage forms

The controlled release pharmaceutical dosage forms disclosed herein may be produced by any suitable process. In some embodiments, the pharmaceutical dosage form is produced by three-dimensional printing (3D printing).

3D printing as used herein refers to the process of producing 3D articles layer by layer according to a digital design. In U.S. Pat. nos.5,204, 055; 5,260,009, respectively; 5,340,656, respectively; 5,387,380, respectively; 5,503,785; and 5,633,0213D, the basic process of 3D printing.

For a detailed description of 3D printing, reference may be made to the above-mentioned patents and applications.

Different 3D printing methods involving different raw materials, equipment and curing conditions have been developed for the production of pharmaceutical dosage forms. These 3D printing methods include binder deposition (see L Gibson et al (2015) additive production technology: 3D printing, rapid prototyping and direct digital production, version 2, Springer, new york; w.e.katstra et al (2000) three-dimensional printing of manufactured oral pharmaceutical dosage forms, controlled release magazines 66: 1-9; w.e.katstra et al (2001) manufacturing complex oral dosage forms by three-dimensional printing, graduate paper of the institute of materials science and engineering, massachusetts institute of technology; h.lipson et al (2013) assembly: 3D printed new world, john wilford father company; g.jonathan,

In some embodiments, the pharmaceutical dosage forms disclosed herein are manufactured by an extrusion process. During the extrusion process, material is extruded from a robot-actuated nozzle. Unlike adhesive deposition which requires a powder bed, the extrusion process can be printed on any substrate. A variety of materials can be extruded to achieve 3D printing, including the thermoplastic materials disclosed herein, pastes and colloidal suspensions, silicones, and other semi-solids. One common type of extrusion printing is fused deposition modeling, which uses solid polymer filaments for printing. In fused deposition modeling, a gear system introduces a filament into a heated nozzle assembly for extrusion (see L Gibson et al (2015) additive manufacturing technique: 3D printing, rapid prototyping and direct digital production, version 2, Springer, N.Y.).

The production instructions for the print job may be generated in a variety of forms, including direct encoding, derivation from a solid CAD model, or other computer interfaces and applications to the 3D printer. These instructions include information on the number and spatial arrangement of drops, general printing parameters such as drop spacing in each linear dimension (X, Y, Z), and the volume or mass of liquid in each drop. For a given set of materials, the parameters can be adjusted to improve the quality of the structure created. The overall resolution of the created structure is the size of the powder particles, the fluid drop size, the printing parameters and the size of the material properties.

Since 3D printing can handle a range of drug materials and can locally control composition and structure, 3D printing is well suited for manufacturing drug dosage forms of the present invention having complex geometries and compositions.

Manufacturing pharmaceutical dosage forms that also facilitate personalization using 3D printing methods. Personalized medicine refers to a dosage form design based on biomarkers to aid in stratification of a patient population to produce treatment decisions and personalization. It is easier to modify a digital design than to modify a physical device. Furthermore, the operating costs of automated, small-scale 3D printing may be negligible. Thus, 3D printing may make multiple small, personalized mass productions economically feasible, enabling the production of dosage forms that are personalized for increased compliance.

The personalized dosage form allows for customized delivery of drug amounts based on the patient's body weight and metabolic level. The 3D printed dosage form can ensure that growing children and highly effective drugs have accurate personalized doses. The personalized dosage form may also combine all patients' medications into a single daily dose, thereby improving patient adherence to medication.

Fig. 11 illustrates a method of manufacturing a personalized dosage form using three-dimensional printing. For each patient, results from various clinical trials can be obtained, including body weight, age, metabolic indicators, genomic biomarkers, and the like. The results of the clinical trial are input into the computer software and combined with the physician's prescription and pharmacokinetic model to design a dosage form for a particular dose and drug combination. The instructions are then sent to a three-dimensional printer to manufacture the dosage form. The resulting dosage form is administered to a patient.

Controlled release of multiple drug matrices

The pharmaceutical dosage forms and methods of the present disclosure may be used to control the release of two or more drug matrices, thereby enabling optimization of drug combinations for a particular medical field. For example, tablets for treating hypercholesterolemia can be designed to release atorvastatin calcium immediately but niacin for extended release. In another example, a non-steroidal anti-inflammatory drug (NSAID) for pain relief is designed to release the NSAID on a sustained basis, but release the H2 receptor antagonist rapidly to prevent NSAID-induced mucosal damage.

In some embodiments, a plurality of compartments are contained within the matrix, each compartment being loaded with a drug matrix. In some embodiments, a plurality of compartments are connected to one another. In some embodiments, the plurality of compartments are not connected to each other. In some embodiments, the drug matrices loaded in different compartments are the same. In some embodiments, the drug matrices loaded in different compartments are different. The pharmaceutical dosage form may be designed to provide simultaneous or sequential release of multiple drug matrices to achieve a synergistic therapeutic effect.

In some embodiments, the release of multiple drug matrices may be simultaneous, sequential, pulsatile, or a combination thereof. Fig. 12A illustrates an exemplary pharmaceutical dosage form that can release multiple APIs simultaneously. Referring to FIG. 12A, the drug dosage form 800 includes three layers of laminate 801-803, each embedded in a different drug matrix. As shown in fig. 12B, when drug dosage form 800 is applied, the drug matrices are released simultaneously but the release rates vary as the layers dissolve.

FIG. 13A depicts another exemplary pharmaceutical dosage form having a simultaneous release profile. Referring to FIG. 13A, the drug dosage form 900 includes three cylindrical compartments 901-903 and these compartments are loaded with three drug matrices. The base of each drug matrix has different solubility and the API is embedded in the base. As shown in fig. 13B, the three APIs are released simultaneously after pharmaceutical dosage form 900 is applied, but at different release rates as the base of the drug matrix dissolves. The release rate of the API can be controlled by the shape of the compartment or the size of the compartment opening.

Fig. 14A and 14B depict another exemplary drug dosage form that can release three APIs simultaneously, and with reference to fig. 14A, the drug dosage form 1000 comprises three pie-shaped segments 1001 with drug matrix embedded therein 1003. As shown in fig. 14C, as the segment dissolves, multiple drug matrices are released simultaneously and the release rate of the drug matrices can be controlled by the solubility of the segment. Referring to fig. 14B, the drug dosage form 1100 includes three pie-shaped segments 1101-1103 surrounded by a shell 1104, the shell 1104 dissolving more slowly than the segments. The release rate of the drug matrix in the potential segment is slowed by the shell 1104 blocking the interface of the segment 1101-1103 with the environment.

Fig. 15A shows an exemplary pharmaceutical dosage form that can sequentially release two APIs. Referring to fig. 15A, the pharmaceutical dosage form 1200 includes a base 1202 having compartments filled with a drug matrix 1202. The matrix 1201 comprises a first API and the drug matrix 1202 comprises a second API. As shown in fig. 15B, following application of the pharmaceutical dosage form, the first API is released as the collective dissolves. The second API is not released until the matrix dissolves and the drug matrix is exposed, thereby achieving a sequential release profile of the various APIs.

Figure 16A illustrates another exemplary pharmaceutical dosage form having a sequential release profile. Referring to FIG. 16A, a drug dosage form 1300 has three cylindrical compartments 1302-1304 loaded with three drug matrices contained within a matrix 1301. The

compartments

1302 and 1304 all have holes that are blocked by a cylindrical plug. Each plug has a different length and/or solubility. As shown in fig. 16B, the various APIs are released sequentially as the plugs sequentially dissolve to open the compartments.

Fig. 17A illustrates an exemplary pharmaceutical dosage form having a simultaneous release or sequential release profile. Referring to FIG. 17A, the drug dosage form 1400 contains within its matrix four segments 1701-1704 having different solubilities. In some embodiments, as shown in FIG. 17B, the drug matrix is embedded in section 1701 and 1704. When the matrix is dissolved, the drug matrix is released simultaneously. In some embodiments, each segment comprises a compartment for holding a drug matrix. As shown in fig. 17C, the drug matrices are sequentially released as the matrix dissolves.

As a result: as shown in fig. 18C, the release profile of benzoic acid was consistent with the model in d.brooke and r.j.washkuhn (zero order administration system: theory and initial test results, journal of medical science, 1977), and was influenced by the interface. Thus, a controlled release profile can be designed based on the pharmaceutical dosage forms of the present disclosure.

Example two

This example describes the design of a pharmaceutical dosage form that can achieve controlled release of drug matrices of different compartments.

Designing a medicine: two drug formulations were prepared using a fused deposition modeling method. The matrix of the pharmaceutical dosage form is composed of copovidone

VA64), 72%, PEG 150018% and

19% of the total composition. The drug matrix consists of 30 percent of moxifloxacin hydrochloride and PEG150070 percent. Fig. 19A and 19B are schematic illustrations of these pharmaceutical dosage forms. Referring to fig. 19A and 19B, a drug dosage form 1600 comprises a substrate 1601 and two

compartments

1602 and 1603 within the substrate. Each compartment is surrounded by

walls

1604 and 1605, respectively. For the first drug dosage form, the two compartments are surrounded by walls having a thickness of 0.75mm and 1.5mm, respectively. For the second pharmaceutical dosage form, the two compartments are surrounded by walls having a thickness of 0.75mm and 2.25mm, respectively.

To detect the release of the drug matrix, the drug dosage form was added to 900mL of pH6.8 phosphate buffer at 100 rpm. The uv absorption of the buffer was measured to determine the release of the drug matrix.

The results of the release assay are shown in fig. 19C and 19D. As shown in FIG. 19C, 20 minutes after the first pharmaceutical dosage form is added to the buffer, the first compartment is opened and the drug matrix in the first compartment is released. After 40 minutes of adding the drug formulation to the buffer, the second compartment was opened. The result is shown in fig. 19D for the second drug dosage form, which was added to the buffer for 60 minutes before the second compartment was opened. Thus, the release profile of the drug dosage form may be controlled by the thickness of the walls enclosing the compartment.
