The present disclosure relates to methods and apparatuses for affecting adherence to medication protocols using medication delivery utensils and, more particularly, to augmenting utensils to include deposited films of organic compounds and film-coated substrates for affecting adherence.
Medications are typically prescribed to patients with specific adherence protocols detailing when and in what amounts to take a prescribed medication. Many of the patients are prescribed multiple medications, with complex adherence protocols, further detailing what order medications are to be taken.
A large proportion of the patients fail to follow the prescribed or recommended protocols for administering medication. In many patient populations, this problem is exacerbated due to intransigence or refusal (e.g., in case of patients suffering from dementia or other forms of mental impairment) and various conditions (e.g., dysphagia) reducing adherence to pill-centric drug regimens. Adding in that oftentimes multiple medications requiring multiple pills are prescribed, medication adherence is simply too cumbersome for too many.
The toll in human lives, the deleterious effect on quality of lives of patients and their loved ones, and the financial burden on individuals, families, and the healthcare system that are caused by poor adherence have far-reaching ramifications on society. Some analyses reveal that well over half of elderly patients do not adhere to their prescribed doses and/or schedules, with 200,000 elderly patients hospitalized annually due at least in part to non-adherence.
The problem of poor medication adherence will likely only worsen with the increasing push for tele-medicine and remote monitoring of patients. As monitoring technology advances, healthcare professionals are increasingly relying upon remote communications with patients to assess their wellbeing. However, there are no effective mechanisms for determining where a patient has adhered to their prescribed medication protocol. Most patients, the data shows, are unreliable in recounting their adherence. And for patients with dementia or other limiting conditions, confirmation is often not an option.
There is a need for effective mechanisms for monitoring of medication and/or supplement adherence protocols and for systems and methods to increase adherence to those protocols.
In response to these large and growing challenges of adherence, the present application provides utensils coated with medication and/or supplements, such that the active ingredient and/or supplement is ingested during a meal, which ameliorates the challenges presented by dementia, dysphagia, intransigence, refusal, and other impediments. Using one or more methods, including but not limited to solvent-free deposition [as shown by Shalev, Shtein et al., Nat Commun 8, 711 (2017), incorporated herein by reference], one or more coatings containing one or more active ingredients (Als) and/or inactive ingredients (excipients) are deposited onto utensils (including but not limited to forks, spoons, chopsticks, cups, sippy cups, lids of cups, lids of sippy cups, lids of reusable water bottles), optionally along with other information (e.g. patient name, dose, meal specification, color, design, etc.). The dose and release of the medication is tuned by adjusting the composition, thickness, and coated region of the layer(s). The invention also includes a system for specifying the type of delivery vehicle (such as type of utensil or container or cup) at the time of prescription or purchase request, any desired personalization, a subscription service for timely delivery of augmented utensils, and/or post-use assessment of medication quality, consumption patterns, with optional feedback on efficacy/adherence. Example benefits of this approach include increased adherence and substantially improved sanitation, as in the case of aseptic coating and packaging of the coated utensil. The latter is particularly important in light of the current COVID-19 pandemic, impacting long-term care facilities heavily; this invention provides for an easy means of offering individually packaged utensils, selectively coated with medicine, reducing instances of physical contact between potentially infected caregivers and the medicines, food, and drink ingested by patients.
In one aspect, described herein is a system for tracking patient medication protocol adherence, a computing device having one or more processors and one or more memories, the computing device communicatively coupled to a communication network, the computing device being configured to allow one or more remote user devices to access the computing device via the communication network; the computing device being further configured to, provide an interface of an application to the one or more remote user devices, receive, via the interface, identification data on a subject, the identification data including a pathology data for the subject, determine from the identification data a desired medication protocol for the subject, and convert the desired medication protocol into augmented utensil configuration data for the subject, the augmented utensil configuration data comprising (i) a desired amount of an active pharmaceutical ingredient (Al) to be administered to the subject using an augmented utensil comprising a working end having layered Al delivery structure formed thereon and (ii) augmented utensil data and/or usage data and/or patient data containing at least one parameter of the augmented utensil; the computing device being communicatively coupled, through the communication network, to a detection stage configured to analyze the augmented utensil and detect an amount of used Al, the computing device being further configured to, receive from the detection stage the amount of used Al and compare the amount of used Al to the desired amount of the Al stored in the augmented utensil configuration data, and from the comparison of the amount of used Al to the desired amount of the Al, determine an adherence score indicating a predicted adherence of the subject to the medication protocol.

In an example, the utensil is a sippy cup. In an example, the utensil is a lid of cup. In an example, the utensil is a lid of sippy cup. In an example, the utensil is a lid of a reusable water bottle.
In some examples, the augmented utensil is patterned with one or more APIs at a working end to allow for oral administration to the subject. In some examples, the utensil is additionally patterned with an excipient agent that may also be a binding agent, a tracking agent, a kinetic agent, a flavor masking agent, a moisture responsive agent, a coloring agent, a temperature responsive agent, a delivery delay agent, a texture agent, a protective layer, an adhesion control agent, or any combination thereof.
In some examples, the augmented utensil contains a system of layered particles, such as a matrix, in which particles are embedded. The matrix may be separated from the utensil's surface by a sacrificial film. When the person is eating (a rice dish, soup, etc.), the coating is stable, save for the sacrificial film that permits the coating to slide off the utensil and into the mouth. Thus, the matrix (and/or particles themselves) may contain a taste-masking agent. Upon transit into the stomach, the matrix and outer layer of the particles dissolve. The remaining particles are surrounded by an acid-impervious (or a buffering) enteric layer, which protects the core of the particle from stomach acid and permits the particles to enter the intestine. This enteric coating dissolves in the intestine and exposes the internal core of the particle. The internal core of the particle may be 100% Al, or Al mixed with other ingredients, which may include excipients, buffers, co-formers, other Als, etc.]

In some examples, the detection station is a chemical compound composition detection system that examines bodily fluid or bodily solids taken from the subject and determines the presence of a tracking agent indicating delivery of the Al. In some examples, the detection station detects an amount of the tracking agent to determine medication adherence. In some examples, the detection station detects the presence of the tracking agent, without detecting an amount, to determine medication adherence.
In some examples, a detection station may be configured to examine a package of utensils to determine how many of the utensils are present or not present in the package and/or to determine an amount of Al remaining on utensils in the package and/or an amount of Al removing from utensils in the package.

The computer-readable media 120 may include executable computer-readable code stored thereon for programming a computer (e.g., comprising a processor(s) and GPU(s)) to the techniques herein. Examples of such computer-readable storage media include a hard disk, a solid state storage device/media, a CD-ROM, digital versatile disks (DVDs), an optical storage device, a magnetic storage device, a ROM (Read Only Memory), a PROM (Programmable Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory) and a Flash memory. More generally, the processing units of the computing device 102 may represent a CPU-type processing unit, a GPU-type processing unit, a field-programmable gate array (FPGA), another class of digital signal processor (DSP), or other hardware logic components that can be driven by a CPU.
In the illustrated example, in addition to storing operating system 138, the memory 120 stores a medication adherence protocol platform 140, configured to execute various processes described and illustrated herein. In an example, the drug-target optimization platform 140 includes a medication protocol platform 142 and an augmented utensil configurator 144, each in accordance with example techniques described herein. Additionally, the memory 120 includes an adherence protocol resolver 146 and plurality of different databases, in this example, a patient data database 148, a utensil data database 150, and a medication data database 152.
The cloud platform 200 includes computer readable memory 204 having an operating system 206 and storing patient data 208, utensil data 210, and medication data 212. The cloud platform 200 further includes processor 214, a set of applications (apps) 216, (optionally) a user interface 218, and a communication module 220 for communication over the network 104.
The set of applications 216 include a medication protocol platform 222, an augmented utensil configurator 224, and an adherence protocol resolver 226. In accordance with processes described and illustrated herein, in some examples, the medication protocol platform (app) 222 is configured to receive and/or generate a medication adherence protocol in response to patient identification data received from the user station 202. In some examples, the medication protocol platform 222 accesses the patient data 208 and the medication data 212 and performs a comparison to determine a medication adherence protocol and includes one or more Als to be administered to a patient. In accordance with processes described and illustrated herein, in some examples, the augmented utensil configurator (app) 224 accesses the utensil data 210 and the medication adherence protocol from the platform 222 and develops an augmented utensil configuration data that includes Al (or “active ingredient”) layered structure data that includes the Als and excipient agents and a layer structure thereof for application to a utensil to form an augmented utensil. The augmented utensil configuration data may further include pattern data defining a location and pattern of the Al layered structure on the utensil to form the augmented utensil. In some examples, the augmented utensil configuration data may be packaged as instructions to be sent to augmented utensil provider (such as 112 in
In accordance with processes described and illustrated herein, in some examples, the adherence protocol resolver (app) 226 is configured to receive usage data for the user station 202 or from a detection station (such as 114 in
In this way, the set of apps 216, which may include GUIs for allowing user access and data entry and authorization, is capable of performing tracking of patient medication protocol adherence. Thus, the medication adherence cloud platform 200 is a computing device able to the receive identification data on a subject, including a pathology data for the subject and determine from the identification data a desired drug regimen in form for the medication adherence protocol. That protocol may be then be converted, by the medication adherence cloud platform 200, into augmented utensil configuration data that is specific to the subject and specific to the type(s) of utensils to be augmented. That augmented utensil configuration data may include (i) a desired amount of one or more Als to be administered to the subject for treating a condition using an augmented utensil having a working end having layered with an Al delivery structure formed thereon. That augmented utensil configuration data may further include, in some examples, at least one parameter of the augmented utensil, such as shape, comprising material, intended packaging, utensil vendor, batch number, storage requirements, serial number, patient data, regimen-related data, compatible foods, etc. Further, the medication adherence cloud platform 200 can receive from a detection station (not shown, examples include station 114 in
The user interface 218 of the medication adherence cloud platform 200 includes (optionally) a display screen 228 that may be used to display a GUI with screens generated by the apps 216 for user station authentication, detection station authentication, and data review and entry related to the processes of the apps 216. Further display screen 228 may be used to display a report of the predicted adherence score for examination by a user, such as a healthcare professional. The user interface 218 may include I/O components for allowing a user to interface with the cloud platform 200 through external interfacing devices, e.g., computers, handheld devices, user terminals, wearable devices, and the like.
In the example of
The user station 202 further includes a processor 240, and user interface 242 having a display screen 244 and I/O components 246. The user station 202 further includes a communication module 248 for communicating with the medication adherence cloud platform 200 over the network 104. A set of applications (apps) 250 includes a GUI interface (app) 252 for interaction by a user and a medication protocol app 254 for the user to be provided with medication protocol data, both via the display screen 244. In some examples, the user station 202 is implemented as a network-accessible computing device, server, or other device that is accessed by the cloud platform 200 without specific user input. Such configurations may be particularly useful for patients incapable of providing user input to a device, such as infirmed patients. In some such examples, the user station 202 is essentially “dark” to the user, and the data in memory 232 is accessed by the cloud platform 200 in an automated manner to access the patient data 236 and the medication data 238. In such examples, the patient or caretaker may simply use the utensils in accordance to protocols and utensils configured in response to and monitored by the cloud platform 200.
At a process 304, the medication adherence cloud platform 200 accesses medication protocol data (e.g., stored at the data 212) identifying an amount of one or more Als to be taken, a medication delivery time frame for each of the one or more Als, preferred taste profile(s), counterindications, co-prescriptions, dosage, expiration dating information, storage instructions, safety instructions, prescribed regimen, regimen starting time and date, regimen ending time and date, patient gender, body weight, height, body mass index, place of administration, manner of administration, administration restrictions (e.g. temperature sensitive Als restricted from certain utensils), preferred foods, counter-indicated foods, person responsible for administration, patient address, service subscription information, service renewal information, etc. The process 304 compares the received authorized amount of consumed Als to the medication protocol data and determines the difference in amount of Al consumed against the amount of Al prescribed in the medication protocol. A process 306 determines a predicted medication protocol adherence, for example, whether the amount of consumed Al is less than the amount of prescribed Al. The process 306 may apply an Al specific rule in making the determination. Some Als, for example, may correspond to medications that allow a percentage deviation in the amount of medication consumed versus the amount of medication prescribed. Other Als may correspond to medications that require stricter adherence and do not allow for a percentage deviation in the amount of medication consumed. The process 306 accessing the medication data 212 applies such Al specific rules and predicts adherence to the medication protocol. That prediction may be a binary scoring, of “ON” protocol or “OFF” protocol, while in other examples, the prediction may be a scored value over a range. The comparison is a prediction in that, while the present techniques provide for highly accurate assessment of Al delivered, the comparison still presumes that the intended subject actually consumed the Al using the augmented utensil.
From the determined predicted medication protocol adherence, a process 308 determines if a change in medication protocol is warranted. For example, the process 308 may access medication protocol data and automatically determine, in the presence of a failure to adhere to the medication protocol, that an increase in one or more of the Als is warranted. If a medication protocol change is warranted, a process 310 passes control to a block 312 that generates updated augmented utensil configuration data, having new Al levels, stored as a new Al layered structure data, that is to be used in forming a new augmented utensil. The medication adherence cloud platform 200 may then transmit the updated augmented utensil configuration data to an augmented utensil provider for fabrication of augmented utensils according to the updated configuration data, at a process 314. The process 312 also sends the predicted medication protocol adherence score to a process 316 were a report is generated for display to a user accessing the medication adherence cloud platform 200. The report may be presented to the user station 202, a healthcare provider computing system, or other system accessing the platform 200.
In some examples, the detection station 400 station may include a microscope or spectroscope. In some examples, the detection station 400 can observe a color change in an indicator dye present on the augmented utensil, and which dye has been introduced to the augmented utensil during manufacturing. In some examples, the detection station 400 can use an indicator or sacrificial substrate that characterizes its contents via an integrated mechanism (e.g., through built-in color filters), without requiring a separate microscope or spectroscope.
In some examples, the computing device 102, the medication adherence cloud platform 200, and/or the augmented utensil fulfillment station 500 may include an analysis stage, such as computer-assisted analysis of experimental data. That analysis stage may be configured to include combinations of test components based on computerized analysis of an initial test or screen of a single or combination of pharmaceutical agents, supplements, and excipient agents. In some examples, the analysis stage performs integrated data analysis that allows for automated decision-making and further analysis of a particular subset of initially-tested combinations of components or variables. The analysis stage can be partially automated, or fully automated.
In some examples, the analysis stage is implemented in part by a control module. For example, the control module may receive data from the analysis stage such as spectroscopic data from a microscopy/spectroscopy module providing response data from applying different drugs to different compounds. Based on the microscopy/spectroscopy response data, the control module may modify combinations of active ingredients and or modify of patterns of active ingredients to be formed as solid films on working end of a utensil. In some examples, the control module may be determine that different drug combinations should be generated by the vapor deposition device for testing of targets in the substrate/assay plate. The control module may be adjusted in response to the microscopy/spectroscopy response data.
At a process 712, the patterning structure of the layer delivery structure from process 710 is determined, and at a process 714 the patterning structure and layer delivery structure are used by a fulfillment station (such as station 500) to generate augmented utensils. That is, in this example, the medication adherence cloud platform 200 communicates the structure data to the fulfillment station for fabrication.
As shown in
The Al layered structures (also termed layered Al delivery structures) may be formed over the entire outer surface 808 or the entire inner surface 806 or patterned over only portions thereof. For example, the layered Al delivery structure may be deposited on a leading tip portion of the upper surface or a leading tip portion of the lower surface, so that the medication is located at the leading end of the utensil 800 to be provided to the subject orally.
As shown in the example of
Thus, more generally, an excipient agent may include flavor masking agent, a delaying agent, a texturing agent, a moisture responsive agent, a coloring agent, a temperature responsive agent, a delivery delay layer film, adhesion control layer, a protective layer, a tamper indicator, contamination indicator, pH sensing/indicating agent, and/or an enteric coating.
As additionally shown in the example of
The Al layer 826 may have a uniform cross-sectional thickness in some examples, while the cross-sectional thickness may vary in other examples. Further still, as shown in an example in
In some examples, the detection station 900 is an imaging station having one or more cameras with a corresponding field of view that includes the sample area and captures images of the sample area, in particular images of augmented utensils or groups of augmented utensils. The captured images may be analyzed, by a computing device of the detection station, to determine an amount of Al consumed, remaining, or a combination thereof. In some examples, the computing device may use a pattern recognition module to assess the captures images to determine an amount of Al consumed, remaining, etc. In some examples, that pattern recognition module may be configured with trained classifiers developed using a machine learning framework, such as classifiers configured as a convolutional neural network.
In some examples, the process in
In various examples, the augmented utensils may be formed by various methods, including for example, methods of (a) forming a compound vapor; (b) passing the compound vapor through a nozzle oriented towards the substrate; (c) depositing the compound on the substrate as a solid; (d) displacing one of the nozzle or the substrate relative to the other; and (e) repeating steps (c) and (d) as required to achieve a desired deposition protocol.
In some examples, the methods provided herein may comprise forming an Al film or Al layered structure of an inorganic compound or an organic compound. In some cases, the methods provided herein comprise an organic compound. The methods provided herein can comprise an organic compound that is between 100 and 5000 g/mol. In embodiments, the organic compound can be between approximately 100 and 1000 g/mol, for example, about 100 g/mol, about 150 g/mol, about 200 g/mol, about 250 g/mol, about 300 g/mol, about 400 g/mol, about 500 g/mol, about 600 g/mol, about 700 g/mol, about 800 g/mol, or about 900 g/mol. In some cases, the organic compound of the disclosure herein can have a vapor pressure of 10−3 Pascals to 106 Pascals, such as, 10−2 Pascals to 105 Pascals, or 1 Pascals to 104 Pascals.
In some cases, the organic compound can comprise a drug, e.g., Al. As noted above, in embodiments, the Al can comprise a compound selected from the group consisting of caffeine, acetaminophen (paracetamol), carbamazepine, 5-methoxy sulfadiazine, ethenzamide, nalidixic acid, isoniazid, furosemide, sulfadimidine, celecoxib, temozolamide, piroxicam, tryptamine, chlorzoxazone, p-coumaric, itraconazole, fluoxetine, telaprevir, sildenafil, theophylline, aceclofenac, 5-nitrouracil, indomethacin, aripiprazole, and atorvastatin, or a mixture thereof.
In some cases, the organic compound is a supplement, excipient agent, or other active ingredient, but not an Al. In various embodiments, the organic compound can comprise an agricultural and/or food industry-relevant compound. In some cases, the compound can comprise a nutritional or food compound, a nutraceutical compound, a cosmetic or personal care compound, a fragrance compound, a colorant or dye, an ink, a paint, and the like, by way of non-limiting example. In some cases, the organic compound can comprise a pesticide, antibacterial, confectionary, seasoning, glaze or a mixture thereof. In some embodiments, the organic compound can comprise gibberellin, benzylideneacetone, or acesulfame.
The present disclosure thus provides for an augmented utensil having one or more active ingredient layers (also termed herein “solid films”). These active layers may be single compound structures or multiple-compound structures. These active layers may be formed of a single Al solid film layer, a single supplement solid film layer, a single excipient solid film layer, or some combination thereof. These active layers may be Al layered structures. In any event, these solid films herein may be formed, for example, of a deposited organic compound, such as a pharmaceutical active agent or a new chemical entity, patterned on a surface of a substrate of the utensil. In certain variations, the surface has a continuous surface coating or film of the organic compound, while in other variations, the organic compound may be applied to select discrete regions of the surface. High quality films or coatings of low molecular organic compounds are formed by the processes according to certain aspects of the present disclosure that have high purity levels. For example, in certain variations, a purity level in one or more regions where of the compound is deposited may be greater than or equal to about 90% by mass of the compound, optionally greater than or equal to about 95% by mass, optionally greater than or equal to about 97% by mass, optionally greater than or equal to about 98% by mass, and in preferred aspects, optionally greater than or equal to about 99% by mass, optionally greater than or equal to about 99.5% by mass, optionally greater than or equal to about 99.7% by mass, and in certain variations, greater than or equal to about 99.99% by mass purity concentration. In certain variations, multiple compounds are present that together or cumulatively have the same purity levels. These compounds may be any suitable active ingredient, including pharmaceutical ingredients or supplements. The deposited solid film may have a surface feature morphology ranging from molecularly flat to high surface area (e.g., a nanostructured surface) with feature sizes in the micrometer or nanometer regimes.
In certain aspects, methods of achieving solid films with high levels of purity and solubility are provided. For example, in certain variations, a solvent-free vapor deposition method is provided that includes depositing an organic compound on one or more discrete regions of a substrate in a process that is substantially free of solvents. By “substantially free” it is meant that solvent compounds or species are absent to the extent that undesirable and/or detrimental effects are negligible or nonexistent. In certain aspects, a vapor deposition process that is substantially free of solvents has less than or equal to about 0.5% by weight, optionally less than or equal to about 0.1% by weight, and in certain preferred aspects, 0% by weight of the undesired solvent species present during the deposition process.
A deposited organic compound may then be present at high purity levels, for example, at greater than or equal to about 99 mass % as described above, in the one or more discrete regions. The process for depositing the organic compound may be selected from the group consisting of, for example: dip-coating, spray-coating, ink-jet printing, organic vapor jet printing, chemical vapor deposition, sputtering, dip-pen coating, soaking, 3D printing (of inorganic, organic, and/or biological materials), vacuum thermal evaporation (VTE), organic vapor phase deposition (OVPD), organic molecular beam deposition (OMBD), molecular jet printing (MoJet), and organic vapor phase deposition (OVPD).
In certain aspects, such a method may include entraining the organic compound in an inert gas stream or vacuum that is substantially free of any solvents prior to the depositing. An inert gas stream can comprise one or more generally nonreactive compounds, such as nitrogen, argon, helium, and the like. In certain variations, the inert gas stream comprises nitrogen.
Because many organic compounds, such as small molecular medicines, have sufficiently high vapor pressures (e.g., from about 1 Pa to about 100 Pa) and relatively low evaporation enthalpies (e.g., 100-300 kJ/mole), high evaporation rates (on the order of grams/(sec*m2)) can be achieved at temperatures of 100°−500° C., without reaching the temperature range where degradation of the compound can occur, even when evaporating at atmospheric pressure. Any process/system that enables deposition of molecular material onto a substrate from a vapor phase, where a source of the molecular material is a solid that evaporates or sublimates, can be used for forming the deposited organic compound pharmaceutical substances. This includes, but is not limited to: vacuum thermal evaporation (VTE), organic vapor phase deposition (OVPD), organic molecular beam deposition (OMBD), and molecular jet printing (MoJet).
However, the processes are not limited to solid sources of the compound. In certain aspects, prior to the entraining, the organic compound is in a form selected from the group consisting of: a powder, a pressed pellet, a porous material, and a liquid, e.g., a solution of a compound. In certain aspects, prior to the entraining, the organic compound is dispersed in pores of a porous material. In other aspects, prior to the entraining, the organic compound is dispersed in a liquid bubbler through which the inert gas stream passes. In yet other aspects, the entraining of the organic compound in the inert gas stream or vacuum is conducted by heating a source of a solid organic compound to sublimate or evaporate the organic compound.
A parameter of the deposition process may be adjusted to control or affect a morphology, a degree of crystallinity, or both the morphology and the degree of crystallinity of the deposited solid organic compound. The parameter is selected from the group consisting of: system pressure, a flow rate of the inert gas stream, a composition of the inert gas, a temperature of a source of the organic compound, a composition of the substrate, a surface texture of the substrate, a temperature of the substrate, and combinations thereof.
In certain aspects, a specific surface area of the deposited organic compound is greater than or equal to about 0.001 m2/g to less than or equal to about 1,000 m2/g. The deposited organic compound may be amorphous. When the deposited organic compound is amorphous, it may further define interconnected particles having an average particle size (e.g., average particle diameter) of greater than or equal to about 2 nm to less than or equal to about 200 nm. In other aspects, the deposited organic compound is crystalline or polycrystalline. In such variations, an average crystal size or domain may be greater than or equal to about 2 nm to less than or equal to about 200 nm.
In certain aspects, the one or more discrete regions on which the organic compound is deposited are continuous so that a solid film is formed on the surface of the utensil or other substrate. In certain variations, the one or more discrete regions of the surface have a high surface area morphology, which may optionally define one or more nanostructures or microstructures. In certain variations, the films are flat (roughness <100 nm). In certain variations, the films comprise micro- and/or nano-structures.
In certain variations, a purity level of the deposited organic compound in the one or more discrete regions is any of those described previously, for example, greater than or equal to about 99.5 mass %. Suitable organic compounds, which may be pharmaceutical active ingredients or new chemical entities, may include by way of non-limiting example, various drugs or potential drugs (e.g., new chemical entities), including anti-proliferative agents; anti-rejection drugs; anti-thrombotic agents; anti-coagulants; antioxidants; free radical scavengers; nucleic acids; saccharides; sugars; nutrients; hormones; cytotoxin; hormonal agonists; hormonal antagonists; inhibitors of hormone biosynthesis and processing; antigestagens; antiandrogens; anti-inflammatory agents; non-steroidal anti-inflammatory agents (NSAIDs); antimicrobial agents; antiviral agents; antifungal agents; antibiotics; chemotherapy agents; antineoplastic/anti-miotic agents; anesthetic, analgesic or pain-killing agents; antipyretic agents, prostaglandin inhibitors; platelet inhibitors; DNA de-methylating agents; cholesterol-lowering agents; vasodilating agents; endogenous vasoactive interference agents; angiogenic substances; cardiac failure active ingredients; targeting toxin agents; and combinations thereof. The description of these suitable organic compounds/pharmaceutical active ingredients/new chemical entities is merely exemplary and should not be considered as limiting as to the scope of compounds or active ingredients which can be applied to a surface according to the present disclosure, as all suitable organic molecules and/or active ingredients known to those of skill in the art for these various types of compositions are contemplated. Furthermore, an organic compound may have various functionalities and thus, can be listed in an exemplary class above; however, may be categorized in several different classes of active ingredients.
Various suitable active ingredients are disclosed in Merck Index, An Encyclopedia of Chemicals, Drugs, and Biologicals, Thirteenth Edition (2001) by Merck Research Laboratories and the International Cosmetic Ingredient Dictionary and Handbook, Tenth Ed., 2004 by Cosmetic Toiletry and Fragrance Association, and at http://www.drugbank.ca/, the relevant portions of each of which are incorporated herein by reference. Each additional reference cited or described herein is hereby expressly incorporated by reference in its respective entirety. In certain variations, the organic compound is an active ingredient compound selected from the group: caffeine, (E)-3-(4-Methylphenylsulfonyl)-2-propenenitrile, fluorescein, paracetamol, ibuprofen, tamoxifen, cannabidiol, and combinations thereof. BAY 11-7082 ((E)-3-(4-Methylphenylsulfonyl)-2-propenenitrile) selectively and irreversibly inhibits transcription factor NF-κB activation (which otherwise regulates expression of inflammatory cytokines, chemokines, immunoreceptors, and cell adhesion molecules) and can inhibit TNF-α-induced surface expression of adhesion molecules ICAM-1, VCAM-1, and E-selectin in human endothelial cells.
In certain variations, the deposited organic compound has an enhanced rate of dissolution in comparison to a comparative powder or pellet form of the same deposited organic compound. Thus, a dissolution rate of the deposited organic compound in an aqueous solution (e.g., approximating physiological conditions) is at least ten times greater than a comparative dissolution rate of the comparative powder or pellet form of the deposited organic compound. In certain variations, a dissolution rate of the deposited organic compound in an aqueous solution is at least fifteen times greater, optionally twenty times greater, and optionally thirty times greater than a comparative dissolution rate of the powder or pellet form of the deposited organic compound.
In certain aspects, a solid film having a high surface area morphology can be formed by a modified organic vapor jet printing (OVJP) process, which eliminates the need for organic solvents and improves dissolution rates for small molecular-based organic materials, like Als. The organic compound(s) that may be deposited by the OVJP process have relatively s and thus are considered to be organic compounds. OVJP processes utilize a carrier gas (e.g., nitrogen) to transport sublimated organic vapor towards a cooled substrate or other target in the form of a focused gas jet. The OVJP process enables scalable patterning of relatively small molecular materials.
In certain aspects, the present disclosure thus contemplates a solid film comprising greater than or equal to about 99 mass % of a deposited organic active ingredient compound having a molecular weight of less than or equal to about 1,000 g/mol. For example, the deposited organic compound may have a molecular weight of greater than or equal to about 100 g/mol to less than or equal to about 900 g/mol. The organic active ingredient compound is preferably a pharmaceutical active or a new chemical entity. The organic active ingredient is any of the compounds described above. By way of example, the deposited organic active ingredient compound may be selected from the group consisting of: anti-proliferative agents; anti-rejection drugs; anti-thrombotic agents; anti-coagulants; antioxidants; free radical scavengers; nucleic acids; saccharides; sugars; nutrients; hormones; cytotoxin; hormonal agonists; hormonal antagonists; inhibitors of hormone biosynthesis and processing; antigestagens; antiandrogens; anti-inflammatory agents; non-steroidal anti-inflammatory agents (NSAIDs); antimicrobial agents; antiviral agents; antifungal agents; antibiotics; chemotherapy agents; antineoplastic/anti-miotic agents; anesthetic, analgesic or pain-killing agents; antipyretic agents, prostaglandin inhibitors; platelet inhibitors; DNA de-methylating agents; cholesterol-lowering agents; vasodilating agents; endogenous vasoactive interference agents; angiogenic substances; cardiac failure active ingredients; targeting toxin agents; and combinations thereof. In certain variations, the deposited organic active ingredient compound is selected from the group consisting of: caffeine, (E)-3-(4-Methylphenylsulfonyl)-2-propenenitrile, fluorescein, paracetamol, ibuprofen, tamoxifen, and combinations thereof.
In certain aspects, the solid film has a specific surface area of the solid film that is greater than or equal to about 0.001 m2/g to less than or equal to about 1,000 m2/g. In certain variations, the deposited organic active ingredient compound in the solid film is amorphous. The solid film may further define particles having an average particle size of greater than or equal to about 2 nm to less than or equal to about 200 nm. Where the solid film is amorphous, the deposited organic active ingredient compound in the solid film is stable for greater than or equal to about 1 month, optionally greater than or equal to about 2 months, optionally greater than or equal to about 3 months, optionally greater than or equal to about 6 months, optionally greater than or equal to about 9 months, and in certain variations, optionally greater than or equal to about 1 year.
In other variations, the deposited organic active ingredient compound in the solid film is crystalline or polycrystalline. An average crystal size may be greater than or equal to about 2 nm to less than or equal to about 200 nm. An average thickness of the solid film may be less than or equal to about 300 nm and an average surface roughness (Ra) of the solid film is less than or equal to about 100 nm.
In other variations, an average thickness of the solid film is greater than or equal to about 300 nm. An average surface roughness (Ra) is greater than or equal to about 100 nm. The film having such a thickness defines a nanostructured surface comprising a plurality of nanostructures having a major dimension of greater than or equal to about 5 nm to less than or equal to about 10 μm. In such an embodiment, the plurality of nanostructures may have a shape selected from the group consisting of: needles, tubes, rods, platelets, round particles, droplets, fronds, tree-like structures, fractals, hemispheres, puddles, interconnected puddles, islands, interconnected islands, and combinations thereof.
Source temperature can be determined via thermogravimetry and tuned to obtain local deposition rate of approximately 0.5 μg/min. The temperature range and carrier gas rate can change depending on system size and configuration.
In certain embodiments, the solid film may comprise a deposited organic compound comprising caffeine. The plurality of nanostructures can have a particular structure, e.g., a needle shape or a tube shape. An average diameter of the plurality of nanostructures can be greater than or equal to about 5 nm to less than or equal to about 10 μm and an average length of greater than or equal to about 5 nm to less than or equal to about 100 μm.
In certain other embodiments, the solid film may comprise a deposited organic compound comprising (E)-3-(4-Methylphenylsulfonyl)-2-propenenitrile (BAY 11-7082). The plurality of nanostructures has a platelet shape, where an average height of the plurality of nanostructures is greater than or equal to about 10 nm to less than or equal to about 10 μm. An average width of the plurality of nanostructures is greater than or equal to about 5 nm to less than or equal to about 10 μm. An average length of greater than or equal to about 5 nm to less than or equal to about 100 μm.
In yet other embodiments, the solid film may comprise a deposited organic compound comprising fluorescein.
In yet further embodiments, the solid film may comprise a deposited organic compound comprising paracetamol. The plurality of nanostructures has a shape selected from the group consisting of: droplet, hemisphere, puddle, interconnected puddle, island, interconnected island, and combinations thereof, wherein an average major dimension of the plurality of nanostructures is greater than or equal to about 5 nm to less than or equal to about 20 μm.
In other aspects, the deposited organic compound according to the present teachings has an enhanced rate of dissolution as compared to a comparative powder or pellet form of the organic active ingredient. A dissolution rate of the deposited organic active ingredient compound in the solid film in an aqueous solution is at least ten times greater than a comparative dissolution rate of the comparative powder or pellet form of the organic active ingredient. The dissolution rate improvement may be any of those previously discussed above.
The films disclosed herein also have improved stability as compared to a comparative film of the active ingredient. In some cases, the films are substantially free of water or other solvents, reducing the rate and extent of degradation of the film.
In certain aspects, the solid film is substantially free of any binders or impurities. A solid film that is substantially free of binders or impurities has less than or equal to about 0.5% by weight, optionally less than or equal to about 0.1% by weight, and in certain preferred aspects, 0% by weight of the undesired binders or impurities present in the solid film composition. In certain variations, the solid film comprises greater than or equal to about 99.5 mass % of the deposited organic active ingredient compound; however, any of the purity levels discussed above may likewise be achieved in the solid film.
In certain aspects, the deposited organic compound on the surface is crystalline or polycrystalline. In other aspects, the deposited organic compound is amorphous. In this manner, substantially pure molecular medicinal films are fabricated that may have high surface area morphologies. The deposited organic compound exhibits enhanced solubility and stability.

In some cases, the method can further comprise moving the substrate under the vapor mixture.
In some embodiments, the substrate can be at a temperature of −100° C. to 100° C., for example, −90° C., −80° C., −70° C., −60° C., −50° C., −40° C., −30° C., −20° C., −10° C., −5° C., 0° C., 5° C., 10° C., 15° C., 20° C., 25° C., 30° C., 35° C., 40° C., 45° C., 50° C., 55° C., 60° C., 65° C., 75° C., 80° C., 85° C., 90° C., or 95° C. In some cases, the substrate can be at a temperature of −50° C. to 50° C., such as, 5° C. to 25° C. The substrate can be made of any material that one of skill in the art would find suitable to coat with the film.
As used herein, the term “substrate” refers to substances that can be used to form a utensil, in particular a working end of the utensil, including but not limited to metal, plastic, wood, ceramic, quartz, glass, paper, composites, or the like, or a mixture thereof, or an aqueous or non-aqueous solvent, e.g., an organic solvent. In embodiments, the substrate can comprise quartz, glass, metal, plastic, ceramic or a combination thereof.
Also described herein are fabricated augmented utensils comprising a solid deposited film formed on a utensil to create an augmented utensil, where that solid film may comprise an Al such, as, an organic compound or a drug, or a pharmaceutical composition comprising at least one organic compound. The solid deposited films may have any of the composition or features described above. The augmented utensils can be prepared as in
In some cases, an augmented utensil is provided that includes a surface of a solid substrate having one or more discrete regions patterned with a deposited organic compound having a molecular weight of less than or equal to about 1,000 g/mol. The organic compound may be any suitable active ingredient including any of the compounds described above. In some examples, the deposited organic compound that forms the active ingredient layer is present at greater than or equal to about 99 mass % in the one or more discrete regions. In some examples, an Al layered structure is used with an Al mixed in a ratio with another compound. In some examples, the purity of the deposited compound will be limited by the starting material, which in some augmented utensil applications can be lower than 99%. In certain aspects, the one or more discrete regions of the surface are continuous and the deposited solid organic compound forms a solid film on the surface of the pharmaceutically acceptable substrate.
In other cases, an augmented utensil is provided that includes a surface of a solid substrate having one or more discrete regions patterned with multiple deposited organic compounds each having a molecular weight of less than or equal to about 1,000 g/mol. The organic compounds are any of the compounds described above. The multiple deposited organic compounds are cumulatively present at greater than or equal to about 99 mass % in the one or more discrete regions. Thus, any of the solid films described above may be disposed on a surface of a solid substrate. Further, the solid substrate may be as described just above.
In some examples, the augmented utensil is formed of a pharmaceutically acceptable substrate defining a surface. The materials selected for the substrate are preferably pharmaceutically acceptable or biocompatible, in other words, substantially non-toxic to cells and tissue of living organisms. Pharmaceutically acceptable materials may be those which are suitable for use in contact with the tissues of humans and other animals without resulting in excessive toxicity, irritation, allergic response, or other problems or complications, commensurate with a reasonable benefit/risk ratio.
In certain aspects, the pharmaceutically acceptable substrate is biodegradable. By biodegradable, it is meant that the materials forming the substrate dissolve or erode upon exposure to a solvent comprising a high concentration of water, such as serum, growth or culture media, blood, bodily fluids, or saliva.
In some examples (such as an example OVJP), the present techniques include an application stage, e.g., jet printing or deposition, optionally followed by reorientation of a substrate relative to a printing means such as a nozzle, and repetition until a desired pattern is obtained to form the augmented utensil having an Al layered structure. The application stage may be part of the augmented utensil provider 112, for example. An application stage may operate using a customized cartridge, such as a dynamic cartridge that provides a local solution intended for use in the near-term. The distribution and application stages can be selected based on the form and nature of the distribution of application. For example, the distribution and application stages can be appropriately modified if a compound is vapor jetted into a liquid or directly onto a surface to provide a film. An application stage may include a module for vapor jetting drug or imaging molecules. Such a module can comprise a source of a compound, heaters to vaporize the compound, a carrier gas inlet and flow channel, a temperature probe, and a mounting plate and tip holder to maintain the module in proper position for control of the vapor jetting application.
