Itraconazole has a very low solubility in water, less than 1 microgram per milliliter. This is an example of the BCSII class with low solubility and high permeability across the gastrointestinal tract.
- the use of the apparatus concerns the preparation of solid oral form comprising a compound which belongs to the class of food supplements, for example a plant extract or any combination of these supplements.
- the dietary supplement is for example curcumin or diferuloyl-methane extracted from the turmeric plant, also called turmeric.
- FIG. 1 illustrates a general view of the apparatus according to the invention with downstream an extruder (not shown);
- FIG. 2 illustrates an apparatus according to the invention with exploded cover which makes it possible to expose a cutting device (1) associated with an orifice (8) of the die of an extruder (3) and a forming system (2) constituted by two co-rotating Archimedean screws.
- a removable heating system is mounted on the two Archimedes screws of the forming system.
- Figure 3 illustrates a profile view of the cutting device
- Figure 4 illustrates a closeup front view of the cutter.
- Figure 5 illustrates the actuation mechanism.
- Figure 5a shows the initial position of the cutting means or knife.
- Figure 5b shows the position of the knife before cutting the ring.
- Figure 5c shows the knife after cutting.
- Figure 5d is a close-up showing the shoulder of the trigger responsible for bypassing the ring by the cutting means or knife.
- Figure 5e illustrates the movement of the knife in its slide arm during the movement of descent and recovery of the knife bypassing the ring.
- Figure 6 illustrates the cooling system of the ring surface by means of an annular air nozzle.
- FIG. 7a illustrates the extrudate forming system by means of 2 Archimedean screws and
- FIG. 7b illustrates the axis of rotation induced on the solid forms by slight axial displacement of the screws and the gap angle.
- Figure 8 illustrates a section in the hot forming system illustrating the heating and cooling zones covering each forming screw.
- the die is a cylindrical connecting piece with the extruder (3), pierced with a circular orifice (8) with a diameter of between 0.5 and 15 mm, depending on the solid shapes that are suitable for obtaining and preferably 6 mm for the solid forms. comprising an active ingredient.
- the die exit surface is made in two stepped planes (9 and 10). The first plane (9) is above the die orifice (8).
- This plane is in sliding contact with a knife (5), which also allows a sharp cut of the ring during the actuation of the knife.
- a second plane (10) parallel to the first but recessed from the die orifice, allows the knife to release the cut ring. This arrangement prevents the cut ring from adhering to the die and thus facilitates its detachment and its fall back to the air gap of Archimedes screws.
- Figure 3 shows the position of the knife (5) end of stroke (C) at the time of the ejection of the solid form to the air gap Archimedes screws.
- the actuation system (6) of the knife (5) has been specifically designed so that its return movement to the initial position (A) above the orifice (8) of the die (4), c ' that is to say, ready to cut the next solid form, does not come into contact with the rod which is extruded continuously.
- the knife (5) is mounted on an arm-slide (11 - Figure 4) with a compression spring (12) which pushes the knife (5) to the maximum of its position forward.
- a cam (14) integral with the knife (5) abuts on a trigger (15) which pivots about an axis (16).
- FIG. 5 illustrates the actuation mechanism and the movement of the cutting device.
- the trigger (15) can not pivot due to the stop (17).
- the trigger (15) therefore forces the knife (5) to move in its slide (11) by compressing its spring (12).
- This movement of withdrawal of the knife in position (B) allows it to avoid contact with the extruded rod as shown in Figure 5e.
- the cam (14) is no longer in contact with the trigger (15) due to a shoulder in the trigger (18-figure 5c and d).
- the spring (12) of the knife pushes it forward in the slide (11) to replace it in its position before cutting (A).
- the cam (14) abuts on the upper face (19) of the trigger (15). It can then rotate in the anti-clockwise direction which is not constrained by the stop (17).
- the trigger (15) retracts and allows the knife (5) to descend freely for the next cut of the rod, to its position after cutting (C).
- the linear motor (7 - figure 3) can be set in acceleration and frequency of operation. These two adjustments make it possible to adapt to the required cutting force that can vary with the outlet temperature of the rod and the extrusion rate in order to reach a cutting length and therefore a mass corresponding to the fixed objective. This is generally of the order of 500 mg with possible variations of a few hundred mg.
- the surface cooling of the ring is performed by an annular blowing system (21) placed opposite the die (4) and concentric with it.
- This system is shown in Figure 6. It comprises a series of 8 small openings (20) placed in communication by a common collector (21). The 8 openings are focused on the die outlet (8).
- the shaping of the oral form is performed by two co-rotating Archimedes screws, preferably in stainless steel (FIG. 7a).
- the two screws are identical.
- the length of the screws is between 400 and 1000 mm, preferably 550 mm, the diameter is between 30 and 100 mm and preferably 50 mm, the pitch may be between 2 and 20 mm and depends on the size of the beads, but is preferably 14 mm.
- the depth of the threads varies between 1 and 10 mm, preferably 3.6 mm.
- the shape of the nets makes it possible to produce solid forms that are almost spherical.
- the relative angular position of the two screws and, consequently, the axial offset of the threads facing each other, can be adjusted so as to produce additional axes of rotation on the solid shapes at the principal axis of rotation parallel to the axis. screw axis.
- These induced secondary rotations generate on the solid forms a movement conducive to the generation of spherical shapes ( Figure 7b). They participate in the erasure of the mark of the cut of the ring and thus remove a forbidden roughness for ingestion of the oral form.
- the relative angular position of the two screws varies between 0 ° and 20 °
- Figure 8 illustrates a heating system (22) at a temperature between 70 and 150 ° C obtained for example by infra-red radiants (24) which are mounted above of the first part of forming to limit the rapid cooling of the solid form coming into contact with the screws.
- This heating system increased malleability of the solid form is ensured in its initial phase of forming.
- a cooling zone (25) obtained by entering air at room temperature has been arranged in order to reach a sufficient solid consistency of the solid forms at the end of the stroke of the screws and at the moment of their evacuation from the system.
- the heating zone (22) is insulated by side walls by means of an upper outer cover and a cover under the screws (23). Inside the heating zone, two IR radiants (24) are placed above the Archimedean screws.
- the air cooling zone (25) is isolated from the heating zone by a movable and adjustable wall (26). The recooling the cooling zone is provided by a fan (27) sucking air through the air gap between the screws and rejecting it to the atmosphere.
