Definitions
- the present invention relates to a device for manufacturing pharmaceutical compositions.
- the manufacture of pharmaceutical compositions is distinguished from the manufacture of other products. Indeed, taking into account on the one hand its importance for society and on the other hand the risks that it is likely to involve for public health, it is subject to specific regulations. In most countries, for example, it is necessary to obtain a marketing authorization before a pharmaceutical composition can be marketed. Administrations, such as the FDA in the United States, or the European Medicines Agency within the European Union (which cooperates with national agencies such as the ANSM in France), control pharmaceutical compositions. The manufacture of the latter must indeed meet certain requirements. In particular, it must comply with what are called GMPs (from the English Good Manufacturing Practices, which describe the minimum requirements that a manufacturer must comply with in his process of production.
- GMPs from the English Good Manufacturing Practices, which describe the minimum requirements that a manufacturer must comply with in his process of production.
- the European Medicines Agency verifies requirements called EU-GMP (European Union GMP), the FDA verifies requirements called CGMP (for current GMP) codified in Title 21 of the federal regulatory code, and the WHO defines also GMPs (“WHO GMP”) verified by a hundred other states.
- EU-GMP European Union GMP
- CGMP for current GMP
- WHO GMP GMPs
- Document US 2018/0080952 A1 discloses an automatic distributor of laboratory solutions.

- FIGS. 4 and 5 are schematic sectional views of a mixing unit according to a second embodiment of the invention, on either side of the same cutting plane.
- FIG. 1 represents a device 100 for manufacturing pharmaceutical compositions, according to an embodiment of the invention.
- the manufacturing device 100 notably comprises: a mixing assembly 102, a processing device 104 and a packaging assembly 106.
- the manufacturing device 100 also comprises an electronic control module 28.
- the mixing assembly 102 comprises: a first enclosure 103 with a controlled atmosphere, and a mixing unit 10.
- the mixing unit 10 is shown alone in FIG. 2.
- This first enclosure is useful as it improves protection against contamination, in particular by microorganisms or by particles which otherwise could have been in the atmosphere and pollute the content of the mixing unit (microbial and particulate load higher in the upstream process), thus facilitating compliance with GMP.
- a traditional pharmaceutical factory entire rooms of the buildings forming the factory can be brought to be placed under a controlled atmosphere in order to guarantee a production respecting GMP. This implies significant constraints relating to real estate.
- the invention proposes to use a manufacturing device comprising a mixing assembly, which is not of a real estate nature.
- the mixing unit 10 comprises in particular: a support 12; a mechanical arm 14 movable relative to the support; a mixing container 16; a plurality of reservoirs 18, 20; at least one device 22 for distributing a starting product; a weighing device 23; a stirring device 24; and at least one analysis device 25, 26.
- the support 12 comprises for example a platform 30, uprights 32 and a rail 34 disposed in height between said uprights.
- the rail 34 extends in a main horizontal direction along the platform 30.
- the mechanical arm 14 is assembled to the rail 34 and provided with mechanical means for sliding along said rail. Said mechanical means, for example rollers, are preferably controlled by the electronic module 28.
- the mechanical arm 14 comprises one or more coupling members 36, 38.
- a first coupling member 36 is for example a gripping member of the mechanical clamp type.
- a second coupling member 38 is able to cooperate with a reservoir 18.
- the mixing container 16 is for example a beaker type container, comprising an upper opening 39.
- the mixing container 16 preferably has a capacity of less than 1 L and more preferably between 10mL and 500mL.
- the reservoirs 18, 20 are movable relative to the support 12 by means of the mechanical arm 14. Each reservoir 18, 20 is capable of containing a quantity of a starting product entering into the composition of a medicament.
- the plurality of reservoirs 18, 20 comprises at least one reservoir 18 of solid and / or at least one reservoir 20 of liquid.
- the plurality of reservoirs 18, 20 comprises at least one reservoir 20 of liquid.
- the plurality of tanks 18, 20 comprises several tanks 18 of solid and several tanks 20 of liquid.
- Each solid tank 18 is capable of containing an amount of a starting product in the form of a pulverulent solid composition.
- the starting product contained in a reservoir 18 is for example a pharmaceutical active principle or an excipient used in the manufacture of medicaments.
- each solid tank 18 of the mixing unit 10 is substantially identical to the tank 18 shown diagrammatically in section in FIG. 3.
- the reservoir 18 comprises a bulb 40, a stirring rod 42 and a dispensing mechanism 44.
- the bulb 40 is for example made of metal or plastic, preferably made of a material called "USP class VI" (and therefore biocompatible, according to the prescriptions in force in the USA) or similar, and defines a closed internal space 46, capable of receiving the powdery solid composition.
- the dispensing mechanism 44 is integral with the bulb 40 and preferably forms a lower wall of the internal space 46.
- the dispensing mechanism 44 is capable of reversibly forming an orifice 50 of controlled size (depending on its degree of opening or closing) at the bottom of said internal space 46.
- this orifice 50 is of construction similar to that of an iris diaphragm of a camera.
- this orifice can be formed using a set of metal strips (for example between five and nine strips), the edge of the strips describing for example a regular polygon.
- the opening or closing of the orifice is obtained by lugs placed on a ring of the iris diaphragm, which allows, mechanically, the opening or closing of the iris diaphragm by a control element placed on the edge of the iris diaphragm.
- the dispensing mechanism 44 includes an iris diaphragm, allowing continuous adjustment between its full opening and maximum closing. The opening / closing of said diaphragm is preferably controlled by the electronic module 28.
- a first end of the stirring rod 42 is received in the internal space 46.
- a second end 48 of said stirring rod emerges outside the bulb 40, preferably in the upper part of said bulb.
- Each liquid reservoir 20 comprises an envelope 52, for example made of stainless steel or in the form of a single-use plastic bag, preferably made of a material known as "USP class VI" or the like.
- Each liquid tank 20 further comprises means of assembly with the dispensing device 22.
- the liquid tanks 20 are in particular intended to contain water or solutions of excipients or of active principle.
- each reservoir 18, 20 comprises an identifier, for example a visual identifier of the QR code type; and the mechanical arm 14 includes a reader capable of recognizing said identifier.
- the distribution device 22 is for example a distribution valve, in particular of the throttle valve or “pinch-valve” type.
- a “pinch-valve” type device consists in causing the liquid to flow through a flexible tube (produced for example using a synthetic polymer) and pinching this tube from the outside (with a throttling device, for example either mechanically or by injecting compressed air which comes to compress this flexible tube by its external face) to control the flow.
- a throttling device for example either mechanically or by injecting compressed air which comes to compress this flexible tube by its external face
- Such a device is also advantageous in that it makes it possible to isolate the throttling device and the liquid (the liquid is only in contact with the internal face of the flexible tube, and the risks of contamination are therefore reduced, thus facilitating compliance with GMP). It is also advantageous by the perfectly watertight closure which it allows.
- the dispensing device 22 is movable relative to the support 12.
- the dispensing device 22 is located above the mixing container 16.
- the weighing device 23, of the precision balance type receives or is capable of receiving the mixing container 16.
- the weighing device 23 is an electronic balance connected to the electronic module 28.
- the stirring device 24 is capable of stirring the contents of the mixing container 16.
- the stirring device 24 receives or is capable of receiving said mixing container 16.
- the stirring device 24 assembled with the mixing container 16 is placed on the scale 23.
- the stirring device 24 is a centrifuge.
- said stirring device is for example an ultrasonic bath, a mechanical stirring of the stirring blade type or a magnetic stirring.
- said stirring device 24 is equipped with an element allowing the cooling or heating of the mixing container 16.
- At least one analysis device 25, 26, connected to the electronic module 28, is intended to control the content of the mixing container 16.
- the mixing unit 10 comprises analysis devices, for example example a pH meter 25 and a spectrometer 26 with or without contact, in particular of the UV or Raman type.
- This device is advantageous in particular in that it allows a fine analysis, relating to the content of a mixing container 16, and operates this measurement almost instantaneously, in contrast to techniques of the prior art such as the technique called HPLC (which often takes between 8h and 24h).
- HPLC which often takes between 8h and 24h.
- the pharmaceutical composition can typically be produced in approximately 2 hours, whereas according to the prior art it takes almost a day.
- the invention also makes it possible to avoid storage and pause times while awaiting analysis results, delays that are encountered in the context of conventional production before the start of a subsequent production stage (critical analysis).
- the complete manufacturing takes at most about three weeks (the manufacturing, in small batches, of pharmaceutical products is accelerated, and the subsequent stages of packaging and quality are also accelerated):
- the pH meter comprises: an electronic reader, fixed to the support 12, and a disposable sensor 29, such as a tablet fixed inside the mixing container 16. Said sensor 29 is connected to the reader.
- the first enclosure 103 of the mixing assembly 102 defines a first chamber 107 in which said first enclosure is able to maintain an atmosphere controlled, for example ISO 7 air class (corresponding to class C pharma), as will be described below.
- This air class (ISO 7) is defined in ISO 14644. It corresponds to a concentration per m 3 of air of maximum 2,930 particles of 5 pm (or more), 83,200 particles of 1 pm (or more) ), and 352,000 particles of 0.5 ⁇ m (or more).
- an ISO 8 class is acceptable.
- a more efficient class (ISO 6) would be technically possible in order to guarantee a less polluted atmosphere. However, the associated costs would be higher and often unjustified in terms of the benefit obtained.
- An ISO 5 class (even more efficient) is practically impossible to obtain, the movements of the solid tanks (if any), the mixing container, the transfer needle, as well as their vibrations, generating in principle particles in excess of the limit defined for ISO class 5.
- the air flows necessary to establish an ISO class 5 environment (corresponding to class A pharma) cause air renewal such as micro-dosing operations (for example using an iris diaphragm) and micro-weighing become insufficiently precise (due to drafts).
- the first chamber 107 is intended to receive the mixing unit 10 previously described.
- the mixing unit 10 and the first enclosure 103 are configured so that a volume of the first chamber 107 is less than 1 m 3 and more preferably between 0.1 m 3 and 0.3 m 3 .
- the room is then considerably smaller than a room in a factory for the production of pharmaceutical compositions. It allows the production on demand of small series of pharmaceutical compositions, for example from 1 to 100 vials (a vial being a small vial). This manufacturing can be made to measure, it is for example personalized according to the profile (age, sex, medical history, other treatments in progress, etc.) of the patient intended to consume the pharmaceutical composition.
- the first enclosure 103 has at least one opening 108, for which sealing means are provided, as described below.
- the mixing assembly 102 further includes a needle 120 disposed in the first chamber 107 and connected by a tube directly or indirectly to the opening 108.
- Figures 4 and 5 show a mixing unit 60, according to a second embodiment of the invention.
- the mixing unit 60 comprises in particular: a support 62; a mixing container 16; a plurality of reservoirs 18, 20; a first 64 and a second 66 device for distributing a starting product; a weighing device 23; a displacement and agitation device 68; at least one analysis device 70, 72; and an electronic control module 74.
- the mixing container 16, the tanks 18, 20 and the weighing device 23 are similar to those described above for the mixing unit 10 in FIG. 2.
