Abstract
Description
[Technical field]
[0001] The present invention relates to a device for administering medicine and a method for managing the expiry date of a medicine dispenser. In particular, the present invention relates to improving the safety features of handheld medicine dispensers such as (but not limited to) dry powder inhalers DPI or pressurized metered dose inhalers pMDI or soft mist inhalers SMI to assist patients in using their medicine correctly. [Background technology]
[0002] It is commonly known to dispense doses of a medicament from a dispenser containing multiple doses of the medicament, the dispenser comprising a dispensing device configured to dispense unit doses of the medicament when a metering device is actuated by a user.
[0003] For example, a multi-dose dry powder inhaler (DPI) is a widely used device available for delivering medicament to the lungs. The applicant's WO 2004 / 012801 discloses a dry powder inhaler comprising a container for containing multiple doses of powdered medicament, a metering member having a dosing recess into which the dose of powdered medicament is loaded, and a mouthpiece communicating with an inhalation channel of the dry powder inhaler. The dry powder inhaler further comprises an inhalation actuation mechanism by which medicament is dispensed for inhalation by the user if or when the user applies an inhalation force above a predetermined level.
[0004] Pressurized metered dose inhalers (pMDIs) are also widely used to deliver medicine to the lungs. European Patent Specification No. 2890437 by the same applicant discloses an aerosol inhalation device comprising a housing adapted to receive an aerosol canister containing a pressurized medicine formulation, a mouthpiece portion through which a user inhales, and a nozzle block having an orifice which serves to propel the aerosol formulation into the mouthpiece portion.
[0005] EP 3370810 discloses an example of a soft mist inhaler (SMI) that includes an atomizer for atomizing a fluid.
[0006] Another type of multi-dose dry powder inhaler is disclosed in WO2004011071 and comprises a blister strip containing a number of individual doses of powdered medicament and a mechanism for accessing these doses, either with piercing means or means for peeling the lid sheet from the base sheet.
[0007] Regardless of the type of dispenser known, the expiration date of the medication is typically printed on the packaging of the dispenser or included in a machine-readable code on a label or tag, such as a bar code or QR code. The expiration date may be printed or included in a machine-readable code when the dispenser is manufactured or packaged.
[0008] In some circumstances, the multiple doses of medicament in a dispenser may be affected by environmental conditions such as humidity and / or temperature and / or light and / or pressure and / or other contaminants that may affect the properties of the medicament (e.g., sterility) once the dispenser is in the hands of a user and first used. For example, a multiple dose of medicament in a housing of a DPI or a canister of a pMDI or SMI is a quantity of material sufficient to provide many unit doses, but which may not be divided into sealed individual doses when contained in the housing. The blisters of a multiple dose dry powder inhaler such as those disclosed in WO2004011071 are not made of suitable materials to protect each single dose from environmental conditions.
[0009] For example, once removed from the sealed packaging, moisture may affect the medication in a dry powder inhaler (DPI) and / or the medication may no longer be sterile, so the product may need to be discarded after a period of use, for example six months after removal from the sealed packaging, even if the dispenser is not empty and has not yet reached its expiration date.
[0010] Also, some types of MDIs are stored in sealed packaging after manufacture and before first use. Other types of MDIs are stored in a refrigerator during distribution and storage at the pharmacy, and when the patient begins using the device, they do not need to be stored in a refrigerator and are stored at room temperature. In that case, the product may have a usable life of three or four months (from removal from the refrigerator) after which it is discarded.
[0011] Therefore, these medications that may be affected by environmental conditions may have two expiration dates: the expiration date mentioned above, and a use-by date, which is calculated from the first use of the dispenser, i.e., the time the dispenser / medication is first exposed to normal environmental conditions, e.g., a DPI is removed from its sealed packaging or an MDI is removed from the refrigerator.
[0012] Because the time when a patient will first use the product is unknown at the time of manufacture, an expiration date cannot be printed on the dispenser or its packaging or included in a machine readable code.
[0013] Thus, known dispensers require the user to calculate the expiration date from the usable period listed in the instruction manual and must make note of when they first started using the product so that they can discard it after the expiration date.
[0014] There is a high risk that users will forget to take notes, and so there is a real risk that drugs will be used after they have lost their efficacy and / or safety, or will be discarded when they are still usable.
[0015] Also, if a user has multiple inhalers, the user must separately identify each inhaler, which can lead to confusion.
[0016] EP 3349719 discloses a method for counting doses of medicament dispensed by an inhaler. WO 2012 / 004298 discloses a drug delivery system comprising a control means adapted to store information indicative of a recommended maximum period of use of the reservoir assembly. US 2014 / 0155827 discloses an emergency drug device, such as an epinephrine auto-injector, including a memory for storing and a display for displaying the expiration date of the drug. EP 3348295 discloses a drug injection device capable of controlling the expiration date of a drug formulation after the formulation has been used. Summary of the Invention
[0017] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to overcome the above-mentioned drawbacks of previously known dispensers.
[0018] A first object of the present invention is to provide a drug delivery system with improved safety.
[0019] It is also an object of the present invention to provide a system that allows users / patients to more easily take their medication.
[0020] It is also an object of the present invention to provide a system that allows a user / patient to order new prescriptions in a timely manner, thereby preventing the risk of drug shortages.
[0021] At least one of the above objects is substantially achieved by a device for administering medicines and a method for managing the expiry date of a medicine dispenser according to the appended claims and / or one or more of the following aspects.
[0022] Aspects of the present invention are disclosed below.
[0023] According to a first independent aspect, a device for administering a medicament comprises: a dispenser including a housing, a dispensing device connected to the housing, optionally a metering device, and a multi-dose amount of a medicament contained in the housing, the dispenser configured to dispense unit doses of the medicament when the dispensing device is actuated by a user; A label or tag including a machine-readable code containing or linked to dispenser data, affixed to the dispenser and / or included or attached to the dispenser packaging, wherein the dispenser data indicates the shelf life of the drug, ΔT in_use a label or tag comprising: a portable electronic device including an electronic control unit and a reader configured to read dispenser data from the machine readable code; an application loaded onto the electronic control unit or, optionally, at a remote location accessed via a network connection (e.g., a web-based application); Equipped with The application is When the reading device reads the machine-readable code on the reading date Tread, the dispenser data and said reading date are received and optionally stored, and if at least one of said data of the dispenser is new, indicating that the machine-readable code has been read for the first time since the manufacture of the dispenser, Reading date Tread and usable period ΔT in_use From expiry date Texp in_use , Texp in_use =Tread+ΔT in_use and / or start an expiration counter, Expiration date Texp in_use and / or usable period ΔT in_use Enable at least one warning depending on the expiration date Texp in_use When the usable period ΔT in_use the portable electronic device issuing said at least one alert when said at least one warning period has elapsed or is about to elapse; is configured to run
[0024] According to a second independent aspect, a method for managing an expiry date of a drug dispenser comprises: Reading and optionally storing dispenser data and a reading date from a machine-readable code of a label or tag fixed to the dispenser of the drug and / or included or attached to the packaging of the dispenser via a reader of the portable electronic device, wherein the dispenser data is used to determine the usable period ΔT in_use and If at least one of the data of the dispenser is new, indicating that the machine-readable code has been read for the first time since the manufacture of the dispenser, Reading date Tread and usable period ΔT in_use From expiry date Texp in_use , Texp in_use =Tread+ΔT in_use and / or starting an expiration counter; Expiration date Texp in_use and / or usable period ΔT in_use enabling at least one warning in response to Expiration date Texp in_use and / or when the usable period ΔT in_use issuing said at least one alert via the portable electronic device when said at least one warning period has elapsed or is about to elapse; Includes.
[0025] According to a third independent aspect, an application for managing the medicament dispenser is loaded or configured to be loaded onto an electronic control unit of the portable electronic device or, optionally, at a remote location accessed via a network connection (e.g. a web-based application), When the reader of the portable electronic device reads the machine-readable code on the reading date Tread, the dispenser data and the reading date are received and optionally stored, and the dispenser data is used to calculate the usable period ΔT of the drug contained in the dispenser. in_use and if at least one of the data of the dispenser is new, indicating that the machine-readable code has been read for the first time since the manufacture of the dispenser, Reading date Tread and usable period ΔT in_use From expiry date Texp in_use , Texp in_use =Tread+ΔT in_use and / or start an expiration counter, Expiration date Texp in_use and / or usable period ΔT in_use Enable at least one warning depending on the expiration date Texp in_use When the usable period ΔT in_use When the time has elapsed or is about to elapse, the portable electronic device issues the at least one warning.
[0026] The present invention helps to ensure that the user / patient does not use the medication after the expiration date. In fact, the expiration counter / clock and the countdown to the expiration date are only started when the dispenser is used for the first time (e.g., removed from the packaging). In this way, the present invention prevents the user / patient from taking the medication after it has passed its expiration date.
[0027] Indeed, after the expiration date, a drug may not be effective within its specifications, and patients may not receive a sufficient dose of the drug to treat their illness. Therefore, any product that has passed its expiration date should be discarded, even if there are doses remaining.
[0028] The present invention is particularly useful, but not limited to, when the medication is prescribed as a "relief" or "as needed" product to be used only when the patient feels short of breath. In such situations, it is very difficult for the patient to know how long the product will last. In such situations, it is much more likely that the device will reach its expiration date and still have a dose remaining.
[0029] The present invention also provides further benefits and technical advantages.
[0030] For example, the present invention may enable a user / patient to take medication more easily and / or allow the user / patient to order new prescriptions in a timely manner, thus preventing the risk of running out of medication.
[0031] Further aspects of the invention are disclosed below.
[0032] In a fourth aspect according to at least one of the first to third aspects, if said data of the dispenser is new, indicating that the machine readable code is read for the first time after the manufacture of the dispenser, the read date Tread is recorded and / or labelled as the date of first use after the manufacture of the dispenser (i.e. when the dispenser / medication is exposed for the first time to normal environmental conditions, such as room temperature and / or moisture and / or light and / or pressure and / or other contamination). Optionally, the read date Tread or the date of first use is used for commercial reasons to know how long it takes from manufacture to reach patients in a particular country to get a better understanding of the supply chain.
[0033] In a fifth aspect related to at least one of the first to fourth aspects, enabling at least one warning includes enabling a final warning.
[0034] In a sixth aspect according to the fifth aspect, the issuing of the at least one warning is performed by an expiration date Texp in_use and / or when the usable period ΔTin_use This includes issuing a final warning when the

[Figure 6] 2 is a flow chart of a method according to the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0078] With reference to the accompanying drawings, Figure 1 shows an apparatus for administering medication. The apparatus 1 comprises a pressurized metered dose inhaler (pMDI) 2, i.e. a portable or handheld medication dispenser, and a smartphone 3, i.e. a portable electronic device.
[0079] The pressurized metered dose inhaler 2 is known per se and comprises a housing 4 comprising a metering device 5 attached to or arranged within the housing 4. As better shown in Figure 2, a reservoir 6 containing a suitable medicament M (e.g. a mono- or multi-component formulation) and provided with a valve 7 is arranged within the housing 4 through an opening 8 in the housing 4. The reservoir 6 may be disposable. The housing 4 also comprises a mouthpiece 9 defining a mouth 10 for dispensing the medicament M released through the orifice of the metering device 5.
[0080] The medication M in the reservoir 6 is a multi-dose medication M, and the metering device 5 enables a user to dispense a unit dose of said medication M each time the reservoir 6 is pressed towards the housing 4.
[0081] The pressurized metered dose inhaler 2 may also be provided with a dose counting unit (not shown) which is configured to operate each time the metering device 5 is actuated and to count, increment or decrement, the number of unit doses dispensed.
[0082] A pressurized metered dose inhaler 2 of this kind is disclosed, for example, in EP 2 890 437 by the same applicant.
[0083] A tag 11 containing a QR code 12 (i.e. a machine-readable code) is affixed to the exterior of the housing 4. As will be described later in this specification, the QR code contains or is linked to data of the pressurized metered dose inhaler 2.
[0084] The smartphone 3 is also known per se and comprises a casing 13 with a display 14 and includes a camera 15 (reader), a memory 16, an electronic control unit 17, a radio receiver 18, a radio transmitter 19 and a GPS receiver 20 (Figure 5). The electronic control unit 17 is operatively connected to the camera 15, the memory 16, the radio receiver 18, the radio transmitter 19 and the GPS receiver 20 for properly managing the operation of the smartphone 3.
[0085] The wireless receiver 18 and the wireless transmitter 19 are configured to communicate with a cellular or mobile network (e.g., a 3G, 4G, or 5G network).
[0086] A GPS receiver is configured to receive signals from satellites of the GPS system.
[0087] The smartphone 3 may also include a Bluetooth transmitter / receiver and a Wi-Fi transmitter / receiver, not shown.
[0088] The device 1 further comprises a software application (App) loaded onto the smartphone 3 and stored, for example in a memory 16 of the smartphone 3, the electronic control unit 17 being configured to execute said application and to carry out the method according to the invention.
[0089] Please refer to the flow chart in Figure 6. The application is configured to read the QR code 12 via the camera 15 and receive and store the pressurized metered dose inhaler (pMDI) 2 data contained in or linked to the QR code.
[0090] For example, in one embodiment, the pMDI data may be contained in a QR code, while in another embodiment, the data may be contained in a web-accessible remote database 100. The QR code may contain a web address for the remote database 100, such that when the user points the camera of the smartphone 3 at the QR code while the application is running, the application may retrieve the data from the remote database 100 and store it in memory 16.
[0091] The data for the pMDI are based on the time period ΔT in_use The hypothetical time of first use is the time when the drug M is first exposed to normal environmental conditions, e.g., room temperature and / or moisture and / or light and / or pressure and / or non-sterile conditions. pMDIs are stored in a refrigerator (i.e., in a controlled atmosphere environment) during distribution and storage in the pharmacy, so the usable period ΔT in_use The usable life of a pMDI, ΔT, typically begins when the product is removed from the refrigerator when it is transported from the pharmacy. in_use is known to the manufacturer and depends on the formulation of drug M and may be, for example, 3 or 4 months or more. in_use is only guaranteed if the user adheres to the product's use and storage recommendations. in_use is known and is part of the pMDI data, but is the expiration date Texp calculated from a hypothetical first use. in_use is not known when the pMDI is manufactured and cannot be part of the pMDI data.
[0092] The pMDI data will typically further include a unique identifier for the pMDI, for example a serial number.
[0093] The data of the pMDI typically further comprises an expiration date Texp, i.e. the expiration date calculated from the date of manufacture of the pMDI. Since the date of manufacture is known, the expiration date Texp is part of the data of the pMDI in the QR code or in the remote database 100. If the drug M is kept safe from normal environmental conditions, for example if the pMDI is stored in a refrigerator or sealed in a package or pouch during distribution and storage in the pharmacy, the expiration date Texp is typically the expiration date of said drug M. This expiration date Texp is also known to the manufacturer and varies depending on the formulation of drug M.
[0094] According to an embodiment, the database 100 stores a number of expiration dates Texp and / or usable periods ΔT in_use Includes the expiration date Texp and the usable period ΔT in_use may vary from one region or country to another, for example due to temperature and humidity differences, and are therefore each linked to one or more geographic regions or countries.
[0095] The application receives parameters reflecting the region or country in which the smartphone 3 is located and / or in which the user resides, and determines the expiration date Texp and / or the usable period ΔT corresponding to that region or country. in_use The parameters reflecting the region or country may be entered by a user or may be obtained by the application from a cellular or mobile network and / or a GPS system.
[0096] As climatic conditions may greatly affect the medication in some countries / regions by being very hot in the summer and very cold in the winter, the application may be configured to receive parameters that reflect the time of year or season in which the dispenser is used.
[0097] The pMDI data may include links via further information and / or applications (e.g., web addresses) to obtain information such as the drug, dosage, place of manufacture, batch number, instructions for use, a video on how to use the device, or disposal instructions.
[0098] The application further: receiving and optionally storing the read date Tread, i.e. the date the QR code was read; comparing the unique identifier of the pMDI with other unique identifiers of pMDIs that may have been previously read and are present in memory 16; It is structured as follows.
[0099] If the unique identifier that has just been read is the first time it has been read or is different from other unique identifiers, i.e. it is a new unique identifier indicating that this is the first time the QR code has been read since the manufacture of the pMDI, storing the read date Tread as the date of first use of the pMDI after manufacture in association with the unique identifier and labelling it; Reading date Tread and usable period ΔT in_use From expiry date Texp in_use "Texp in_use =Tread+ΔT in_use " and / or a use-by-date counter, i.e., a usable period ΔT in_use Start a timer with a length of time equal to Use expiry date Texp in_use Compared with the expiration date Texp in_use occurs after the expiration date Texp and / or the usable period ΔT in_use elapses after the expiry date Texp, issue a warning (e.g., an audible or visual signal or vibration) via the smartphone 3, allowing the user to immediately return the pMDI to a pharmacy to obtain another one, otherwise Enable advance warning and expiry date Texp in_use and / or the usable period ΔT in_usea pre-warning (e.g., a message, an audible or visual signal, or a vibration) is issued via the smartphone 3 before the expiration date of the product (e.g., a few weeks or days in advance to alert the user when the product is nearing the end of its useful life, so that a new product can be prescribed by a doctor and obtained at a pharmacy before the expiration date of the old product); Enable Final Warning and Expiration Date Texp in_use and / or when the usable period ΔT in_use The final warning is issued when the time has elapsed.
[0100] The application may also be configured to adjust the Tread or first use date and / or to manually enter the Tread or first use date via the portable electronic device 3, which is useful if the user forgets to read the machine-readable code 12 when the dispenser 2 is used for the first time and / or removed from its packaging.
[0101] The application may be configured to allow for further notifications and / or links.
[0102] The application may be further configured to receive a medical prescription for a user / patient, said medical prescription including the number of doses per unit time that the user should take (e.g., two doses per day) and an overall expected time ΔT assum (e.g., 90 days) or the total number of doses the user should take (e.g., 180 doses).
[0103] The application also estimates the overall expected time ΔT assum Consider or calculate the total expected time ΔT assum Use Expiry Date Texp in_use and / or usable period ΔT in_use It is designed to be compared with
[0104] The application also displays the expiry date Texp in_use is the total expected time ΔT assumand / or before the end of the available period ΔT in_use is the total expected time ΔT assum In this way, it is possible to detect whether a pMDI contains a large number of unit doses and the usable period ΔT in_use If the time is too short, the user may be informed that they cannot use the drug at all.
[0105] The application may optionally provide notifications when the user should use the product, which may be input by the user so that notifications occur at preferred times when the patient is instructed to take their medication, for example 8:00 am and 6:00 pm.
[0106] If the unique identifier that has just been read is identical to one of the other unique identifiers in memory 16, i.e., it is not a new unique identifier, which indicates that the QR code has already been read; Via the display 14 of the smartphone 3, a status (message, image, etc.) is displayed indicating that the QR code has been read and the remaining usable period ΔT remain is displayed.
[0107] Thus, the application allows for the management of multiple pMDIs or other inhalers or dispensers and ensures that the appropriate inhaler is discarded when the final warning is given.
[0108] Figures 3 and 4 show another type of inhaler, namely a dry powder inhaler (DPI) 21. This may for example be the dry powder inhaler disclosed in the applicant's WO 2004 / 012801, and this dry powder inhaler 21 may be used in a similar manner to that described above, together with the application and smartphone 3.
[0109] The dry powder inhaler 21 shown in Figures 3 and 4 comprises a housing 22 defining a mouthpiece 23 and a mouthpiece cover 24 configured to open and close the mouthpiece 23. A container 25 within the housing 22 contains multiple doses of a powdered medicament M (e.g. a single-component or multi-component formulation). A metering member 26 having a dosing recess into which a dose of the powdered medicament M is loaded may be provided in communication with the inhalation channel 27 and the mouthpiece 23. The dry powder inhaler 21 further comprises an inhalation actuation mechanism configured to dispense the medicament M for inhalation by the user if or when the user applies an inhalation force above a predetermined level.
[0110] During distribution and storage at the pharmacy, the dry powder inhaler 21 is typically contained in a sealed package 28 (FIG. 4) to protect it from environmental conditions. The sealed package may be a moisture-proof foil laminate pouch and may, for example, contain a desiccant that is disposed of when the pouch is opened.
[0111] 4, the tag 11 containing the QR code 12 is attached to the sealed packaging 28, and the user reads the QR code via the camera 15 of the smartphone 3 when removing the dry powder inhaler 21 from the sealed packaging 28 upon first use. In another embodiment, the QR code may be printed on the housing 22 of the dry powder inhaler 21.
[0112] Dry Powder Inhaler 21 Shelf Life Date Texp shelf varies by formulation and can be 18 months.
[0113] Also, the expiration date Texp in_use varies by formulation and can be 6 months.
[0114] According to other embodiments of the invention, the device 1 may comprise other types of dispensers including a housing, a dispensing device connected to the housing, and a multi-dose medicament contained in the housing (i.e., the multi-dose medicament in the housing is a quantity of material sufficient to provide a number of unit doses, but which quantity of material is not necessarily divided into sealed individual doses when contained in the housing), the dispensing device configured to dispense unit doses of the medicament when actuated by a user. For example, the dispenser may be an MDI with pre-filled blisters as disclosed in WO2004011071, or a soft mist inhaler (SMI) as disclosed in EP3370810.
[0115] According to an embodiment, the application may not be loaded onto the electronic control unit, but may instead be a web-based application accessed via a network connection.
[0116] Instead of a QR code, other tags or labels with machine-readable codes may be employed, for example bar codes or RFID (Radio Frequency Identification) tags or BLE (Bluetooth Low Energy) beacons. The reader is therefore an optical reader (like the camera 15) or an RFID reader or a BLE reader. These kinds of tags (RFID or BLE readers) may incorporate a "write function" so that the data of the dispenser 2 and / or the expiry date Texp in_use For this purpose, the portable control unit 3 stores the data of the dispenser 2 and / or the expiry date Texp in_use A writing device is provided for writing the expiration date Texp to the tag. If the label or tag is a BLE beacon, it can automatically emit a signal when used for the first time. This signal is the expiration date Texp in_use can be picked up by the home environment (e.g., Alexa®) or home hub, which can store the information in the cloud.
[0117] A tag or label containing the machine readable code may be attached to the housing of a dispenser such as the pMDI 2 disclosed above, or to a package such as the DPI 21 disclosed above, or may be attached to a sheet inserted into the dispenser package 28 or secured to the disposable reservoir 6 of the pMDI 2. If the components of the DPI are to be reused, the machine readable code is attached to the disposable drug containing housing. [Explanation of symbols]
