In one embodiment of the present invention, the oral administration formulation may be a controlled-release formulation, specifically, a delayed-release and / or sustained-release formulation. The "controlled-release" means controlling the release rate of the active ingredient of the formulation, and the release may be used interchangeably with dissolution, and in the present invention, the controlled-release means delayed-release and / or sustained-release. The "delayed-release" means that the drug of the formulation is not released in the body for a certain period of time after taking the formulation. In one embodiment of the present invention, the drug in the internal space may be released 5 hours after taking the formulation. Specifically, the drug contained in the internal space of the formulation may be released in an amount of 5% or less of the total drug weight for 5 to 12 hours after taking the formulation.For example, the drug contained in the inner space may be released in an amount of 5% or less of the total weight over a period of about 5 hours, about 6 hours, about 7 hours, about 8 hours, about 9 hours, about 10 hours, about 11 hours, or about 12 hours, but is not limited thereto. The "sustained release" may mean that the release of the drug of the formulation proceeds slowly over a period of time or longer. In one embodiment of the present invention, the drug may be released from 4 hours to 12 hours from the start of the release of the drug in the inner space after taking the formulation, and specifically, it may include that 85% or more of the total weight of the drug in the inner space is released from 4 hours to 12 hours. For example, the drug in the inner space may be released for about 4 hours, about 5 hours, about 6 hours, about 7 hours, about 8 hours, about 9 hours, about 10 hours, about 11 hours, and about 12 hours after the drug release initiation, and more specifically, more than 85% of the total weight may be released, but is not limited thereto. In one embodiment of the present invention, the drug may be released in an amount of 5% by weight or less of the total weight of the drug from 5 hours to 12 hours after taking the formulation. In one embodiment of the present invention, the oral administration formulation may be included such that after taking the formulation, about 5% by weight to 50% by weight of the total weight of the drug from the inner space is released from 2 hours from the release initiation, and more than 85% of the total weight of the drug from the inner space is released from 4 hours to 12 hours from the release initiation. In one embodiment of the present invention, the oral administration formulation may include a formulation in which, when the formulation is added to a test solution at 37°C and pH 1.2 in a rotating paddle device having a paddle that rotates at 50 rpm, the drug contained in the internal space of the formulation is released in an amount of 5 wt% or less of the total weight of the drug over a period of 5 to 12 hours.In one embodiment of the present invention, the oral administration formulation may include a formulation in which, when the formulation is added to a test solution at 37°C and pH 1.2 in a rotating paddle device having a paddle that rotates at 50 rpm, about 5% to 50% by weight of the total weight of the drug in the internal space is released within 2 hours from the start of release, and more than 85% by weight of the total weight of the drug is released within 4 hours to 12 hours from the start of release. In the formulation according to the present invention, since the release of the drug in the internal space is delayed by about 5 hours to 12 hours, the effect of the drug (e.g., melatonin) present in the internal space of the formulation does not appear immediately after taking the formulation, so that the drug in the internal space of the formulation is delayed-released at a desired time so that the effect of the drug can be exhibited at a desired time. Specifically, the tablet according to embodiments of the present invention does not require taking the preparation according to the time at which the medicinal effect should appear, and even when taken together with a drug that should have a rapid medicinal effect, the medicinal effect appears after a certain period of time, thereby significantly improving the convenience of taking the medication for the patient. More specifically, when the drug in the inner space of the preparation is melatonin, the preparation of the embodiment of the present invention can be effectively applied to improving jet lag. For example, according to an embodiment of the present invention, when melatonin is included in the inner space of the preparation, melatonin can exert its pharmacological effect after a certain period of time when the preparation is taken, thereby effectively preventing or treating insomnia or sleep disorders due to jet lag while improving the convenience of taking the medication for the patient. In particular, when a preparation including melatonin in the inner space is taken together with a stimulant such as caffeine, drowsiness and fatigue can be minimized immediately after taking the preparation due to the stimulant ingredient such as caffeine, and after a certain period of time, melatonin is released, allowing sufficient sleep to be achieved.In embodiments of the present invention, when the drug contained in the internal space is melatonin, the formulation can be such that 5% or less of the drug contained in the internal space of the formulation is released for 8 to 12 hours after taking the formulation in the morning. Alternatively, when the formulation is taken in the afternoon, 5% or less of the drug contained in the formulation can be released for 5 to 8 hours. In addition, the formulation of the present invention provides sustained-release properties so that the drug release continues for about 4 to 12 hours from the start of drug release, and thus can be applied to drugs with a short half-life and a rapid disappearance of drug effect, so that the drug effect can be maintained for a desired period of time. In one embodiment of the present invention, the oral administration preparation may be included without limitation as long as it is in a form that can be administered orally, and specifically, the preparation may be in a form in which a drug can be contained in an internal space that is surrounded by a shell and is distinct from the outside, and more specifically, the oral administration preparation is in the form of a capsule, and even more specifically, may be in one of a disk shape, a fillet shape, and a round shape. The "disk shape (100)" may mean a preparation having a three-dimensional shape in which the upper part (130) and the lower part (120) of the preparation are oval-shaped, and the height (123) is shorter than the long axis (121) of the upper and lower ovals, as shown in FIG. The "fillet shape (200)" may mean a preparation having a three-dimensional shape in which the upper part (230) and the lower part (200) of the preparation are rectangles with curved corners, and the height (223) is shorter than the length of the width (221) of the upper and lower rectangles, as shown in FIG. The above "round type (300)" may mean a three-dimensional shape in which the upper part (330) and the lower part (320) of the formulation are rectangles in the form of semicircles rather than straight lines, as shown in Fig. 1c, and the height (323) is shorter than the horizontal length (321) of the upper and lower rectangles.In one embodiment of the present invention, the oral administration preparation may include one manufactured using 3D printing.

In the step (c), the step of injecting the drug and pharmaceutically acceptable additives into the formulation may include, but is not limited to, pausing the 3D printer for 30 to 60 seconds. The method for manufacturing a formulation according to the present invention uses a method in which the shell composition is mixed in powder form and directly fed into the silo of a 3D printer, and then melted and printed from a nozzle, rather than being manufactured into a filament, so that the manufacturing process is simple, and it has the advantage of being able to apply polymers that are not suitable for filaments and pharmaceutically acceptable additives. In addition, compared to the FDM method that uses a filament that requires at least two heat treatments, the 3D printing method used in the present invention can use relatively heat-sensitive raw materials because heat is applied only during the printing process. Therefore, it is free in the use of raw materials, and since there is no cost for manufacturing filament, there is an advantage in terms of cost. The 3D printing method can manufacture a formulation customized to the individual, taking into account the severity of the disease, the timing and dosage of the drug administration, etc. Accordingly, the present invention can provide a customized formulation so that patients suffering from jet lag can appropriately select it according to the arrival time of the jet lag area by manufacturing formulations with different shell thicknesses using a 3D printer.

Specifically, the formulation according to the embodiments of the present invention swells to the extent that it is difficult to pass through the pylorus of the stomach, adheres to the gastric mucosa, and remains in the stomach for a long period of time, thereby easily controlling the desired release of the drug.

Referring to FIG. 1A, the formulation (100) is composed of a shell surrounding a lower portion (120), an upper portion (130), and an internal space (110). Here, the "internal space (110)" refers to a three-dimensional empty space formed at a predetermined thickness (dll to 13) from the outermost portions of the lower portion, upper portion, and side surfaces of the formulation (100).

In the above diagram la, a drug may be positioned in the internal space, and the release rate of the drug in the internal space may be controlled by controlling the thickness of the shell, and a certain amount of empty space exists in the internal space, so that when the formulation of diagram la is taken, the formulation swells, and the drug may be released over a long period of time. The above description of the structure of the la formulation is substantially equally applicable to the remaining embodiments, i.e., the formulation (100), lower portion (120), upper portion (130), internal space (110), and thickness (dll to dl3) in the la formulation can also be substantially equally applied to the formulations (200, 300), lower portion (220, 320), upper portion (230, 330), internal space (210, 220), and thickness (d21 to d23, d31 to d33) in the lb formulation and the lc formulation as long as they are not contradictory to each other.The descriptions in the formulations, pharmaceutical compositions, food compositions and manufacturing methods discussed above, unless they are contradictory, can be substantially equally applied to the formulations (100, 200, 300), the lower part of the shell (120, 220, 320), the upper part of the shell (130, 230, 330), the internal space of the shell (110, 210, 220), the thickness of the shell (dll to dl3, d21 to d23, d31 to d33), the drug contained in the internal space and / or the shell, the release of the drug from the formulation, etc., as shown in FIG. 2. FIG. 2 exemplarily illustrates a method for manufacturing a formulation according to FIG. 2. Referring to FIG. 2, the formulation of the present invention comprises: (1) a step of melting and outputting a shell composition mounted on a 3D printer; (2) a step of stacking a lower part (120) of the formulation having a predetermined thickness (dll); (3) A step of forming a structure having an internal space (110) by printing only a perimeter of a certain thickness (dl2); (4) A step of temporarily stopping the printer and then loading a drug and / or a pharmaceutically acceptable additive into the internal space (110); and (5) A step of operating the printer again after loading the drug and / or the pharmaceutically acceptable additive to laminate the upper part (130) to a certain thickness (dl3). The description of FIG. 2 is also merely an example of the form of FIG. 1a, and the manufacturing method according to FIG. 2 can be substantially equally applied to the formulations according to FIG. 1b and FIG. 1c as long as they are not contradictory, and is not limited to the structure. In addition, the descriptions of the formulations, pharmaceutical compositions, food compositions, and manufacturing methods examined above can be substantially equally applied to the manufacturing method of FIG. 2 as long as they are not contradictory. Hereinafter, the following examples are presented to explain the present invention in more detail. However, the following examples are merely illustrative of the present invention, and the content of the present invention is not limited to the examples disclosed below.A shell composition for manufacturing a formulation using the compositions of Examples 1 to 3 and a 3D printer was manufactured. Specifically, a mixture of a composition according to the following Table 1 was mixed in a V-MIXER for 20 minutes at 90 rpm to manufacture a homogeneously mixed composition of Examples 1 to 3. The HPC used in this example is HPC_LF (Manufacturer: Ashland co. Ltd., Trade name: Klucel), and the HPC_LF used has a molecular weight (MW) of 95,000 Daltons, a viscosity of 75-150 mPa-s (Measurement conditions: Brookfield LVF viscometer, 25 °C, 5% aqueous solution), and a particle size of which 85% or more passes through a 30 mesh sieve and 99% or more passes through a 20 mesh sieve. In order to manufacture the formulation using the compositions of Examples 1 to 3, a self-made 3D printer was used, and the formulation was modeled using 3D printing slicer software. The 3D printing of the present invention was performed using a Screw Direct Powder One Nozzle. The compositions of Examples 1 to 3 manufactured above were put into the 3D printer, and the lower part and the side perimeter of the shell were printed according to the conditions of Table 2 below, and before printing the upper part, printing was temporarily stopped, and then a mixture of melatonin and microcrystalline cellulose was injected into the internal space. The mixture injected into the internal space was manufactured with a composition of 9 parts by weight of microcrystalline cellulose per 1 part by weight of melatonin. After the injection of the mixture of melatonin and excipients was completed, printing of the upper part of the shell was completed, thereby manufacturing the formulation.
[0031] Table 11
[0032] Table 2 Manufacturing of formulations using a 3D printer of Examples 4 to 10 The compositions of Examples 4 to 10 were manufactured with the same composition as the composition of Example 2 of Table 1 above, and the manufacturing method of the formulations was also manufactured in substantially the same manner as the manufacturing method of Examples 1 to 3, except that the output conditions of Table 3 below were used.
[0033] Table 3 <Experimental Example 1> Evaluation of physical properties of the formulation
[0034] To evaluate the physical stability of Examples 1 to 3 manufactured through 3D printing, the swelling ratio, physical strength, and adhesive strength were evaluated. Swelling ratio W evaluation Swelling ratio is based on the diagonal length of the formulation before swelling, and the ratio of the increased diagonal length of the formulation compared to before putting it into the solution is evaluated by measuring the length of the formulation after 30 minutes and 1 hour under the conditions of the dissolution test solution (pHl .2), and the results are shown in Fig. 3. As confirmed in Fig. 3, Example 1 showed the highest swelling ratio of 130% after 1 hour, and Examples 2 and 3 showed similar results at 120%. Physical strength (mm) evaluation The physical strength was measured using a Texture Analyzer (TA. XTplusC) under the conditions of detection speed 200 / s and test speed 0.5 mm / s. When a pressure of 0.65 N was applied, the depth to which the formulation was pressed was measured, and the results are shown in Fig. 4. As can be seen in Fig. 4, it was confirmed that the physical strength decreased as the content of PEO increased. In other words, Example 3, which did not contain PEO, was the hardest, and Example 1, which had a PEO content of 32 wt%, had the lowest strength. Adhesion (N) Evaluation The adhesion was measured using the same device as the physical strength measurement, and the measurement conditions were as follows. The maximum value of the (-) force applied when the formulation was detached after being adhered to the probe was measured under the conditions of a detection speed of 200 / s and a test speed of 0.5 mm / s, and the results are shown in Fig. 5. As can be seen in Fig. 5, the adhesion was the highest in Example 3, and decreased in the order of Example 2 and Example 1. That is, the adhesion increased as the content of PEO included in the shell decreased (Fig. 5). However, it was confirmed that this was not a significant difference as in the swelling ratio.
[0035] <Experimental Example 2> Evaluation of in-vitro release characteristics according to shell composition Melatonin dissolution characteristics of the formulations of Examples 1, 2, and 3 of the present invention were evaluated as follows. The dissolution characteristic evaluation was performed according to the 2nd dissolution test method (paddle method) of the Korean Pharmacopoeia. As the dissolution conditions, the formulation was added to 500 mL of a solution adjusted to pH 1.2 using a dissolution tester, and the test solution was collected at 1-hour intervals for 0 to 27 hours, and the released melatonin content was measured using HPLC. At this time, the temperature of the test solution was maintained at 37 °C ± 0.5 °C, the rotation speed of the paddle was 50 rpm, and a sinker was not used. As a result of evaluating the dissolution characteristics of the formulations of Examples 1, 2, and 3, it was confirmed that the release was delayed for a certain period of time in all three compositions, and it was also confirmed that a sustained-release characteristic in which the drug was slowly released after the initiation of release was exhibited. Specifically, as confirmed in Fig. 6, Example 1 delayed the release for up to 8 hours, and about 85% of the drug was released 9 hours after the initiation of the release of melatonin, and the release of the drug was completed after 10 hours. In addition, Example 2 delayed the release for up to 9 hours, and about 85% of the melatonin was released 11 hours after the initiation of release, and Example 3 started the release after 12 hours, and about 85% of the melatonin was released 11 hours thereafter. It was confirmed that all of the above example compositions were capable of delayed release and sustained-release of the drug.
[0036] <Experimental Example 3> Evaluation of in-vitro release characteristics according to shell thickness Formulations having the same composition as the shell composition of Example 2, but having thicknesses of 1.0 mm (Experimental Example 4) and 1.5 mm (Experimental Example 5) and having a disk shape were manufactured according to the method described above under the conditions of Table 3. The evaluation of release characteristics was performed on the formulations of Examples 2, 4, and 5, and was carried out in the same manner as in Experimental Example 2, and the results are shown in Fig. 7. As confirmed in Fig. 7, it was confirmed that the release could be delayed for 5 to 12 hours depending on the thickness of the shell. In Example 2, which had the thickest shell thickness of 2 mm, melatonin release started after 11 to 12 hours, 85% of the drug was released after 8 hours from the start of release, and release was completed after 10 hours. Example 4, in which the shell thickness was 1 mm, the drug release commenced after 5 hours and continued for 6 hours from the initiation of drug release, so that 85% of the drug was released 6 hours after the release of melatonin, and the drug release was completed 7 hours after the initiation of drug release. Example 5, in which the shell thickness was 1.5 mm, the drug release commenced after 8 to 10 hours and continued for 10 to 11 hours.
[0037] <Experimental Example 4> Evaluation of release characteristics according to the shape of the formulation Evaluation of in-vitro release characteristics according to the shape of the formulation Formulations having the same composition as the shell composition of Example 2, the same thickness of 1 mm, and each having a disk shape (Example 4), fillet shape (Example 6), and round shape (Example 7) were manufactured according to the method described above under the conditions of Table 3. The evaluation of release characteristics was performed on the formulations of Examples 4, 6, and 7, and was carried out in the same manner as in Experimental Example 2, and the results are shown in Fig. 8. As confirmed in Fig. 8, even when the shapes of the formulations were changed to fillet shape (Example 6) and round shape (Example 7) with the same composition and thickness, a release pattern similar to that of the disk shape (Example 4) was exhibited. Specifically, Examples 6 and 7 delayed the release of melatonin for up to 8 hours, and the release of melatonin lasted for up to 4.5 hours after the initiation of release. Evaluation of in vitro release characteristics according to the thickness of the round formulation Formulations having the same composition as the shell composition of Example 2 and having a thickness of 0.5 mm (Example 8), 0.7 mm (Example 9), 1.0 mm (Example 7), and 1.5 mm (Example 10) based on the upper and lower surfaces, respectively, were manufactured according to the method described above under the conditions of Table 3. The evaluation of release characteristics was performed on the formulations of Examples 7, 8, 9, and 10, and was carried out in the same manner as in Experimental Example 2, and the results are shown in Fig. 9. As confirmed in Fig. 9, when the same composition was used in the round formulation, the thickness was changed to 0.5 mm (Example 8), 0.7 mm (Example 9), 1 mm (Example 7), and 1.5 mm (Example 10), and the release characteristics were evaluated, and it was confirmed that the release was delayed by 5 to 10 hours through thickness adjustment. In addition, Examples 8 and 9, which had thin shell thicknesses of 0.5 mm and 0.7 mm, delayed the release by 5 to 6 hours, and Examples 8 and 9, which had thin shell thicknesses of 1 mm (Example 7) and 1.5 mm, delayed the release by 5 to 6 hours.As it increased to 5 mm (Example 10), the release showed a pattern of increasing to 7 hours and 10 hours.
