Description

Blessed Calcium and its manufacturing method {THE WATER-INSOLUBLE CALCIUM COVERED WITH AMORPHOUS SURFACTANT AND METHOD FOR PREPARING THE SAME}

The present invention relates to a barrier-free calcium (Calcium) and a method for producing the same. More specifically, the present invention relates to a non-facing surface calcium having a very excellent emulsification stability without containing a solubilizing agent of calcium, which is a poorly soluble substance, and a method for producing the same.

Calcium is the most abundant mineral in the body, with 99% stored in the bones and teeth mainly in the form of calcium phosphate, and the remaining 1% spreads in the blood and cells. (1) In the body, calcium is widely used in the formation of skeleton and teeth, blood coagulation, relaxation of muscle contraction, neurotransmission, regulation of nerve excitement, regulation of cell membrane permeability, absorption of vitamin B12 and fusion and division of cell membrane. have.

Calcium plays an important role in reducing the incidence of hypercholesterolemia, arteriosclerosis, hyperlipidemia, hypertension, as well as bone diseases such as osteoporosis.

In the case of using various natural calcium materials as calcium agents, in order to benefit health, they must first be solubilized and not ionized or suspended by calcium ions to precipitate. In addition, in order to absorb the calcium ingested in food or sanctions into the body, it must first disintegrate and dissolve in the stomach to be ionized as calcium ions. The rate of calcium absorption is affected by the rate and solubility of calcium ingested. In other words, the faster the calcium disintegration rate and dissolution rate and the higher the degree of ionization, the higher the absorption rate. For this purpose, methods of adding organic acids have been used to enhance calcium solubility for solubilization of calcium.

However, due to the solubility of the calcium and the sour taste of the organic acid used to increase the bioabsorption rate, there is a limit to contain the calcium content enough to meet the nutritional recommended amount. In addition, even if the acidic acid is removed and used, it has been reported that ionization calcium, which is a water-soluble calcium agent that merely increases calcium solubility compared to insoluble calcium agent, does not improve the absorption rate of calcium.

Therefore, in order to solve the above problems, it is necessary to minimize the calcium precipitated in the digestive tract by increasing the stability of the calcium emulsified by the surfactant, etc., and also by administering a small amount of medicine by drastically increasing the content of the drug trapped in the surfactant. Even if it is possible, it should be able to exhibit sufficient pharmacological effects.

It is an object of the present invention to provide a barrier-free calcium comprising a calcium and a surfactant as poorly soluble substances, and further to provide anhydrous barrier-free calcium that produces the barrier-free calcium when dissolved in water.

Another object of the present invention is to provide a method for preparing the barrier-free calcium and anhydrous calcium-free interface.

In order to achieve the above object, the barrier-free calcium according to an embodiment of the present invention is 10 to 200 weight of the surfactant having two or more alkyl chains attached to 100 parts by weight of calcium (Calcium) and the hydrophilic portion with respect to the calcium In addition, the surfactant is in the form of an amorphous (amorphous) surrounding the outer surface of the calcium is bonded to the form of the emulsion dissolved in water, the calcium attached to the surfactant has an average diameter of 0.5 to 30㎛ The average range of sizes is within ± 200% of the diameter.

The barrier-free calcium may further include a fatty acid between the surfactant and the calcium.

The fatty acid may be included in 10 to 1000 parts by weight based on the calcium.

The fatty acid may be selected from the group comprising caprylic acid , caprylic acid , stearic acid, palmitic acid, myristic acid, lauryl acid and oleic acid.

The surfactant may be selected from the group containing egg yolk lecithin, soy lecithin and hydrogenated lecithin.

The surfactant may be one containing 70% by weight or more of phosphatidylcholine (PC).

According to another embodiment of the present invention, when the anhydrous unbounded interface calcium is dissolved in water, it produces the non-destructive interface calcium.

The anhydrous non-interfacial interface calcium may further include an organic solvent having a polarity as a mixed adjuvant.

The organic solvent having the polarity may be two or more -0H groups.

The polar organic solvent may be selected from the group containing glycerin, 1,3 butylene glycol, propylene glycol, dipropylene glycol, ethylene glycol and polyethylene glycol.

According to another embodiment of the present invention, a method for preparing anhydrous non-interfacial calcium includes: (a) mixing a surfactant having two or more alkyl chains attached to a hydrophilic portion and a polar organic solvent having two or more -OH groups; (b) raising the temperature of the mixture of step (a) to raise the fluidity of the mixture; (c) adding calcium as a poorly soluble substance to the mixture of step (b); (d) phase mixing the calcium-containing mixture of step (c) using a mixer comprising a mixing blade structure having the concept of phase mixing; And (e) solidifying the phase mixed mixture of step (d).

The number of each blade of the unit blades constituting the mixed blade structure may be 20 or less.

The number of unit blades constituting the mixed blade structure may be 1 to 50.

According to another embodiment of the present invention, a method for preparing a barrier-free interface calcium comprises adding water to the barrier-free calcium prepared by the method for preparing the barrier-free interface calcium.

Hereinafter, the present invention will be described in more detail.

Conventionally, it is not without the concept of using a surfactant to dissolve a poorly dissolved material in the form of liposomes or emulsions. However, the stability of the composition was excellent in the case of the conventional method of solubilizing poorly soluble substance in the form of liposomes, but there is a problem that the content of the poorly soluble substance that can be dissolved is very small. A large amount, poor emulsification stability, or toxicity of a substance used as a solubilizer (such as cremophore) has caused serious adverse effects on the human body. Therefore, in order to overcome the above-mentioned problem that the content of the dissolvable poorly soluble substance and the point of emulsification stability and adverse effects on the human body is required a new type of material that has not been conventionally.

Since the new material is a new concept material that does not exist in the prior art, a definition of a new term that may include all the properties of the new material is necessary. Therefore, the barrier-free calcium according to an embodiment of the present invention refers to the novel type of material, and the barrier-free calcium used in the present specification means that it belongs to the concept of a barrier-free material including the following characteristics.

(a) First, the surfactant used should be at least two alkyl bodies attached to the hydrophilic portion of the surfactant. This is an important technical feature in that the liposomes of the prior art are required to be as standardized as possible, unlike the standardized ones.

(b) Second, the diameter of the poorly soluble substance to which the surfactant is attached is 0.5 to 30 µm, preferably 1 to 10 µm, and more preferably 1.5 to 5 µm. Compared to the liposome having a diameter of 45 to 200 nm in the prior art, it has a size of several tens to hundreds of times, thereby greatly increasing the amount of melting of calcium as the size of the poorly soluble substance surrounded by the surfactant increases. It can be analyzed.

(c) Third, the poorly soluble substances to which the surfactant is attached have a very high homogeneity in size. The poorly soluble material to which the surfactant is attached has an average size of -200% to + 200% based on the total diameter. Preferably it is -30%-+ 30%, More preferably, it is -10%-+ 10%. This is an important factor in delaying recrystallization. The higher the homogeneity, the greater the effect of delaying recrystallization.

(d) Fourth, unlike the liposomes, the poorly soluble substance to which the surfactant is attached should not be standardized as much as possible. The amorphous state of the poorly soluble substance to which the surfactant is attached contributes significantly to the rate of recrystallization. As the degree of amorphousness increases, the rate of recrystallization may be delayed. In this case, however, there may be no complete amorphous form. In this regard, the material of the present invention may not be called completely amorphous, but the term amorphous is used in describing the material of the present invention in that it is oriented in the amorphous form.

(e) Fifth, the poorly soluble substance to which the surfactant is attached is directed to an emulsification type as a form dissolved in water.

Therefore, when the poorly soluble substance is calcium, calcium, which shows the above five characteristics, is defined as a barrier-free calcium (a shortened term of calcium covered with a surfactant on the outside of an emulsion-soluble water-soluble amorphous form).

In addition, anhydrous unbounded surface calcium defines solid calcium, such as solid calcium which turns into a waterless interface calcium when it is put into water.

The term solubilizing, dissolving or dissolving herein may include conventional dissolution, emulsification, liposome forms, and the no- north interphase state used herein. In a narrow sense, it can be different from the general dissolution of a barrier-free material. However, in the present specification, when using poorly soluble substances in foods or pharmaceuticals, it means that the recrystallization is extremely delayed in the macroscopic aspect (the concept of melting according to the present specification is used unless otherwise described separately). The above case is used as a comprehensive meaning.

As used herein, the term poorly soluble may mean that the pharmacologically active agent is not dissolved in an aqueous solution (eg, water, physiological saline, injectable dextrose solution, etc.). USP / NF generally expresses solubility as the volume of solvent required to dissolve 1 gram of drug at a specific temperature (eg, 1 g aspirin in 300 ml H2O, 5 ml ethanol at 25 ° C). In other references, solubility can be described using more subjective terms, such as those given in Table 1, set forth in Remingtons Pharmaceutical Sciences, Mack Publishing Co., Easton, PA, latest edition.

Technical term 1 volume  Volume of solvent required per solute Very High Availability <1 High availability 1 to 10 Availability 10 to 30 Insufficient Availability 30 to 100 Low availability 100 to 1000 Very low availability 1000 to 10,000 Substantially insoluble or insoluble > 10,000

Therefore, the term poorly soluble in the present invention, when water is used as a solvent, belongs to the four solubility categories in the lower table of Table 1, namely, insufficient solubility, low solubility, very low solubility and pharmacological activity belonging to virtually insoluble or insoluble. It may include a formulation.

The poorly soluble substance may include a pharmaceutically active agent, a diagnostic agent, a nutritional agent, and the like.

Anhydrous uncalcified calcium according to an embodiment of the present invention is that the surfactant having two or more alkyl chains attached to the hydrophilic portion is included in 10 to 200 parts by weight based on 100 parts by weight of calcium (Calcium). In the case of conventional liposomes, 500 to 1000 parts by weight of a surfactant is used to dissolve 100 parts by weight of calcium. However, in the case of the barrier-free calcium according to the present invention, the calcium can be dissolved in water by using a surfactant in the above range. As a result, the content of the surfactant can be greatly reduced. In addition, in the case where the surfactant having two or more alkyl chains attached to the hydrophilic part is included in excess of 200 parts by weight, when excessively used, the content ratio of calcium is lowered compared to the amount of the surfactant, and the efficiency may be significantly reduced. When it is included in less than 10 parts by weight it is difficult to contact while completely surrounding the calcium in amorphous form, the efficiency of dissolving in water as an emulsified type may be reduced.

In addition, preferably, the surfactant having two or more alkyl chains attached to the hydrophilic portion may be included in 20 to 80 parts by weight, more preferably 40 to 60 parts by weight. According to the above range, the efficiency of the surfactant dissolved in water while amorphous surrounding the outer periphery of the calcium can be significantly increased.

Anhydrous uncalcified calcium according to an embodiment of the present invention has a diameter of 0.5 to 30 μm of the unbounded interface calcium to which the surfactant is attached. When the diameter of the barrier-free calcium exceeds 30 μm, the internal crystallization is increased in the vicinity of the hydrophobic group, and thus the sustaining effect of the emulsified state may be lowered.

The diameter of the barrier-free calcium is very important in terms of functional dissolution of poorly soluble calcium. In other words, the diameter of the barrier-free calcium is an indicator of the size of the barrier-free calcium because it is an important factor in determining the amount of calcium that the hydrophobic group of the surfactant can bear. In the case of liposomes, it can be said that calcium is completely dissolved near the hydrophobic group, but since the size of calcium without barrier is much larger than that of liposomes, at least part of the calcium inside the body without calcium is partially internally It may be crystallized. However, since the outer surface of the calcium is amorphous and surrounded by the form of the surfactant, the barrier-free calcium is emulsified and dissolved in water, and its size is so small (although much larger than liposomes), it is completely dissolved. Even if it is not, the premise is that it is not harmful to the human body (animal body when used in an animal) as long as the emulsion type is maintained.

On the other hand, preferably the diameter of the barrier-free calcium is 1 to 10 ㎛, more preferably 1.5 to 5 ㎛. According to the above range can be maintained in a stable emulsification state of the highest stability of the barrier-free interface calcium.

Anhydrous uncalcified calcium according to an embodiment of the present invention is that the average range of size is -200% to + 200% based on the diameter. This can be said that the homogeneity is very high. According to the above range, recrystallization of the barrier-free calcium may be remarkably delayed to increase its stability, and if it is outside the above range, such stability may be lowered.

In addition, preferably the anhydrous calcium has an average range of the size may be -30% to + 30% based on the diameter, more preferably -10% to + 10%. According to the above range, since recrystallization is further delayed, there is an advantage in that the stability of the anhydrous calcium is very high.

The precise mechanism of whether the recrystallization is delayed when the homogeneity is high is not yet fully understood. However, the van der Waals attraction between the barrier-free calcium particles is offset by the repulsive force due to the zeta potential of the barrier-free calcium particles.

More specifically, according to Stern's double-layer theory, negatively charged particles on the surface of the particles attract opposite charges in the water, that is, positive charges, because the negatively charged particles attempt to be electrically neutralized. To achieve. This layer is called a fixed layer (Stern layer). The outer layer is called the diffused layer (Guoy layer). The outer layer is the diffusion layer (Guoy layer). As the particles move, the ions outside the diffusion layer stay without migration, and the surface of the ion layer moving with the particles is called the shear surface. There is a potential on the particle surface, the fixed layer, and the diffusion layer, and since the potential of the particle surface can not be measured directly, it can be indirectly detected by measuring the potential at the front surface surrounding the particle when the particle moves. The potential is called the zeta potential. The dislocation is greatest at the particle surface and decreases away from the particle. When two particles with the same charge approach each other, they are pushed against each other by electrostatic repulsive force, which reduces the van der Waals attractive force acting between the particles to keep the particles stable.

In summary, if the homogeneity of the barrier-free calcium particles is remarkably high and the sizes of the particles are about the same, the repulsive force due to the inter-particle zeta potential and the attraction force due to van der Waals can be said to be almost the same. If nearly identical, each attraction and repulsive force are canceled (or even better when repulsive force is superior). The recrystallization of the barrier-free calcium particles can be delayed as much as possible.

As described above, in order to significantly increase the homogeneity of the barrier-free interface calcium, an inline mixer including a mixing blade structure having a concept of reparation mixing may be used.

The meaning of the liquid phase mixing is 10 at regular intervals as shown in FIG. 5 so that the liquid passing through it can be cut in the form of 2 ⁿ , 3 ⁿ , 4 ⁿ and 5 ⁿ or the like, or the mixture can be finely homogenized. The following blades, preferably four or less blades repeatedly change direction and pass through the ducts arranged inside in a fixed manner, so that the solution is conceptually cut every time through each unit of the blade. Say mix.

In the present invention, a mixer capable of such phase mixing is defined as a mixer for phase mixing. The liquid phase mixing mixer is meant to include a structure capable of the liquid phase mixing in any part of the mixer, and it is not limited to all pipelines having a liquid phase mixing structure.

In the prior art, there is a mixer or homogenizer having a stronger stirring or homogeneous capability than the liquid mixing mixer such as a microfluidizer or a high-pressure homogenizer. Surprisingly, however, the barrier-free calcium of the present invention is produced only through the reparation mixing mixer, and cannot be manufactured through a general mixer, as well as a very powerful stirrer or homogenizer such as the microfluidizer and the high pressure homogenizer.

Specifically, a powerful stirrer or homogenizer such as a high pressure homogenizer or a microfluidizer is a mechanism for crushing and stirring a specific material by transmitting a strong physical force to one or more places. Therefore, the site where the physical force is transmitted may be strongly pulverized and agitated, but when it is moved away from the site, the physical force transmitted is weakened, which is inevitably less pulverized than the site where the physical force is transmitted. Accordingly, since the size of the ground particles is different depending on the stirring position, the average size of the stirred particles may be finely ground and agitated, but the homogeneity of the resulting particles may be reduced.

However, in the case of using the liquid phase mixing mixer, the mixture containing the surfactant and calcium added is quantitatively 1/2 to 1/10 each time it passes the unit blade included in the internal liquid mixing mixer tube. The process is divided and stirred. In addition, as the unit blade passes through the process repeatedly, the content and ratio of the surfactant and calcium to be bound can be quantified while being proportional to the dose and the ratio of calcium and the surfactant to be initially introduced.

Although the content or ratio of the surfactant and calcium in the initial stirring step is not quantitative, the proportion and amount of the calcium and the surfactant to be bound may be quantified as the stirring process proceeds. As a result, when the surfactant and calcium quantified in terms of proportion and quantity are bound as described above, the size of the surfactant is bound to be almost the same, and thus, the homogeneity of the resulting material is significantly increased.

Therefore, the use of the liquid mixing mixer can be said to be one of the most essential components in the present invention. However, the present inventors first discovered calcium in a non-interfacial state, and derived the concept thereof, and the substance invention is protected by the substance itself, and the scope of the present invention cannot be limited to the manufacturing room thereof. Is not limited to that according to the liquid mixing mixer.

In other words, even if it is not the method of using the liquid mixing mixer, there is a sufficient possibility that a homogenizer or stirrer capable of producing the barrier-free calcium, which is substantially pursued by the present invention, may appear. . For example, many homogenizers or stirrers of various types that can amplify the homogeneity can be considered in addition to the phase mixing mixer, and by using a mixer or homogenizer having the strong stirring ability or homogeneous capacity, and using a membrane filter or the like. A method of ensuring the homogeneity can be considered. Therefore, the calcium barrier-free interface prepared according to the other method other than the compensation mixture mixer is also considered to be within the scope of the present invention.

The barrier-free calcium may further include a fatty acid between the surfactant and the calcium.

When the fatty acid is further included, the fatty acid is intertwined irregularly with the alkyl chain of the surfactant attached to the calcium, thereby preventing the surfactant from being formalized. Therefore, there is an effect of significantly lowering the probability of recrystallization by combining with the calcium.

In addition, since the fatty acid can dissolve the calcium well in the molten state, when the calcium is added in a state where the fatty acid is mixed with the surfactant, the dispersion and homogeneity of the calcium may be increased.

The fatty acid may be included in 10 to 1000 parts by weight based on the calcium. When the fatty acid exceeds 1000 parts by weight, the dispersion and homogeneity improvement effect according to the amount of the fatty acid is no longer improved. When the fatty acid is included below 10 parts by weight, the recombination prevention of calcium, the dispersion degree and the homogeneity improvement effect are improved. Can be degraded.

In addition, preferably the fatty acid may be included in 10 to 500 parts by weight, and more preferably 20 to 100 parts by weight. Although not limited to the above range, the dispersion and homogeneity of calcium may be the highest when the above range.

The fatty acid may be selected from the group comprising caprylic acid , caprylic acid , stearic acid, palmitic acid, myristic acid, lauryl acid and oleic acid. In the case of using the fatty acid, there is an advantage that the recombination prevention, dispersion degree improvement and homogeneity degree improvement of calcium are higher.

The surfactant may be lecithin, and the lecithin may be one selected from the group comprising egg yolk lecithin, soy lecithin, and hydrogenated lecithin. However, the present invention is not limited thereto.

In the case of using the lecithin, it is possible to dissolve in water as an emulsified type by being emulsified by surrounding the calcium. The egg yolk lecithin, soy lecithin and hydrogenated lecithin have the advantage of preventing the recombination of the calcium, the effect of improving dispersion.

In addition, the surfactant may be a PC (Phosphatidylcholine) is contained in more than 70% by weight. However, the present invention is not limited thereto, and when the PC content is included in an amount of 70% by weight or more, it may be excellent in preventing recombination of the calcium and improving dispersion degree with high purity.

Anhydrous barrier-free calcium according to another embodiment of the present invention is to produce the barrier-free calcium when dissolved in water.

The anhydrous barrier-free calcium is provided in the form of an oral dosage form, and the anhydrous barrier-free calcium is dissolved in water, and the surfactant is dispersed in water when the surfactant is dispersed in water, and the surfactant is added to the outside of the calcium. It forms an emulsion type in the form of being bonded while being surrounded in an amorphous form, and is dispersed in water as the form of the emulsion type to produce the barrier-free material.

The anhydrous non-interfacial interface calcium may further include an organic solvent having a polarity as a mixed adjuvant.

Since the mixed adjuvant is often a solid and calcium and the surfactant should be in a solution state in order to make the liquid phase mixture, for this purpose it serves to create a mixture of the appropriate viscosity for the liquid, and at the elevated temperature (Calcium) And surfactant to prevent burning.

The mixed adjuvant is not to be included in the barrier-free calcium, but the preparation of the anhydrous-free interface calcium, since the initial calcium and the surfactant may include a fluidized bed process, the mixed adjuvant is the anhydrous barrier-free calcium Can be included. In particular, the fluidized bed process may be desirable to add a polar organic solvent to the initial calcium and the surfactant to a more stable fluidized bed.

The organic solvent having the polarity may include a -0H group and two or more -0H groups. Unlike the barrier-free calcium, the anhydrous barrier-free calcium contains an organic solvent having a polarity such as -OH. In general, the organic solvent is mostly dissolved in water when the anhydrous unbounded surface calcium dissolves in water to maintain a state that most of the organic solvent is not attached to calcium. When the —OH group of the organic solvent is two or more, the solubility in water may be increased, and the anhydrous non-interfacial interface calcium may form the non-interfacial interface calcium.

In addition, preferably, the organic solvent may be selected from the group containing glycerin, 1,3 butylene glycol, propylene glycol, dipropylene glycol, ethanol, ethylene glycol and polyethylene glycol. However, the present invention is not limited thereto.

When the organic solvent is used, a more stable fluidized bed process can be achieved, and the anhydrous barrier-free calcium can be dissolved in water so as to form an excellent barrier-free calcium.

According to another embodiment of the present invention, a method for preparing anhydrous non-interfacial calcium includes: (a) mixing a surfactant having two or more alkyl chains attached to a hydrophilic portion and a polar organic solvent having two or more -OH groups; (b) raising the temperature of the mixture of step (a) to raise the fluidity of the mixture; (c) adding calcium as a poorly soluble substance to the mixture of step (b); (d) phase mixing the calcium-containing mixture of step (c) using a mixer comprising a mixing blade structure having the concept of phase mixing; And (e) solidifying the phase mixed mixture of step (d).

According to an embodiment of the present invention, the number of each blade of the unit blades constituting the mixed blade structure may be 20 or less.

This has the advantage that the ratio and amount of the calcium and surfactant are more quantified as the number of blades of the unit blades constituting the mixed blade structure increases, but the internal pressure of the reparation mixing mixer increases, which may cause the mechanism to break. Because. That is, when the number of the blades of the unit blades constituting the mixed blade structure exceeds 20, there may be a problem that the internal pressure of the phase mixing mixture is excessively increased.

In addition, preferably the number of each blade of the unit blades constituting the mixed blade structure may be 10 or less, more preferably 1 to 4. Therefore, according to the above range, the ratio and amount of the calcium and the surfactant can be more quantified while maintaining the internal pressure of the liquid mixing mixer.

According to one embodiment of the present invention, the number of unit blades constituting the mixed blade structure may be 1 to 50.

When the number of unit blades constituting the mixing blade structure exceeds 50, the internal pressure of the mixing mixture for mixing may increase, and if there is less than one, the mixing of phases may not be achieved.

Preferably it may be 2 to 30, more preferably may be 4 to 15. According to the above range can stir the material quantitatively while increasing the stability of the liquid phase mixing mixer, it can increase the homogeneity of the material produced.

On the other hand, the terminology herein in the unit blade constituting the mixed blade structure and each blade of the unit blade constituting the mixed blade structure can be understood through FIG.

When using the phase mixing mixer, the flow rate and the stirring time passing through the phase mixing mixer may be different for each phase mixing mixer used. However, the five conditions that must be in order to become the barrier-free material have been defined, and it will be necessary to repeat compensation mixing as necessary until the object becomes such.

On the other hand, using the liquid phase mixing mixer in order to produce the barrier-free calcium of the present invention can be an important component. However, it is not limited to use another stirrer in parallel with the use of the phase mixing mixer.

In the present invention, the matters related to the manufacturing method of the anhydrous barrier-free calcium are the same as the barrier-free calcium described above, so that the description thereof is omitted in order to prevent the present invention from becoming too complicated.

According to another embodiment of the present invention, a method for preparing a barrier-free interface calcium comprises adding water to the barrier-free calcium prepared by the method for preparing the barrier-free interface calcium.

The barrier-free calcium and anhydrous-free calcium in accordance with the present invention may be prepared as pharmaceutical compositions.

The pharmaceutical composition of the present invention can be administered to mammals such as rats, mice, livestock, and humans in various routes such as oral or parenteral routes such as oral, rectal or intravenous, muscular, subcutaneous, intra-uterine, Can be administered by injection.

The appropriate dosage of the pharmaceutical composition of the present invention may vary depending on factors such as the formulation method, administration method, age, body weight, sex, pathological condition, food, administration time, administration route, excretion rate, . The dosage of the pharmaceutical composition of the present invention may be administered once or several times a day in an oral dosage form of 0.1 to 100 mg / kg on an adult basis. It is recommended to apply 1 to 5 times a day in an amount of 3.0 ml to continue for 1 month or more. However, the dosage is not intended to limit the scope of the present invention.

The pharmaceutical composition of the present invention may be formulated into a unit dose form by formulating it using a pharmaceutically acceptable carrier and / or excipient according to a method which can be easily carried out by a person having ordinary skill in the art to which the present invention belongs. Or by intrusion into a multi-dose container. The formulations may be in any form suitable for pharmaceutical preparations including oral formulations such as powders, granules, tablets, capsules, suspensions, emulsions, syrups and aerosols, external preparations such as ointments and creams, suppositories and sterile injectable solutions, , Dispersants, or stabilizers.

The barrier-free calcium of the present invention has an advantage of increasing the amount of calcium that can be dissolved by several tens to hundreds of times compared to the method of solubilizing calcium in the conventional liposome form or emulsion form.

Accordingly, the calcium-free interface of the present invention does not use any solubilizer, such as cremofo, which has the potential to cause fatal side effects in the human body, thereby minimizing side effects in the human body. In addition, when administered to the human body without the barrier-free calcium can significantly increase the AUC (curve area under blood concentration) compared to the conventional method, it is possible to significantly improve the pharmacological effect compared to the conventional calcium preparations. In addition, the calcium in the abdominal interface has excellent emulsification stability, which hardly precipitates in the digestive organs such as the esophagus, the stomach, the duodenum, the large intestine, and the small intestine, thereby minimizing the side effects caused by calcium precipitation.

In addition, the method for producing a non-interfacial calcium of the present invention enables to produce the non-interfacial calcium. In addition, according to the anhydrous barrier-free calcium of the present invention and its manufacturing method, the barrier-free calcium can be utilized.

[ Experimental Example  One : Free-standing interface  Evaluation of Calcium Physical Property]

Experimental Example  1-1: Identification of amorphous state

The amorphous surface calcium prepared by the method of Example 3 was confirmed using an electron scanning microscope (SEM). Photographing was performed at 7000 times and 1000 times magnification, and specific results are shown in FIG. 10. The picture shown in blue letters in Figure 10 is calcium itself, it can be seen that the arrangement is very regular as shown. Even though it is not dispersed in water by the regular arrangement of calcium crystals, it is in a state where recrystallization occurs even if it is dispersed by physical force in a moment. However, when the photograph of the result of Example 3 is shown in a red color photograph taken by a scanning electron microscope, it is confirmed that the amorphous crystals are irregularly dispersed. Due to the amorphous form of calcium and the irregular arrangement of crystals, it is very easy to disperse water, and it is maintained for a long time (more than 3 years at room temperature).

Experimental Example  1-2: Evaluation of homogeneity and dispersibility

The dispersibility, homogeneity, and particle size of the barrier-free calcium phase can be roughly determined by measuring the potential difference using a Zeta-Potential Analyzer, but this method is limited to confirm the presence or absence of recrystallization in the colloid system. There is. Therefore, the size and homogeneity of emulsified particles according to aging changes were confirmed directly by using a microscope, and its stability was confirmed. In the particle photographs of Table 7 and FIGS. 12 to 27, no recrystallization of calcium was observed according to changes over time, and the particle size also showed a uniform distribution of _______ to ________ μm. You can see that.

Generally, when the particle size is different according to aging, the particles are coalesced and agglomerated due to the difference of the repulsive force and the attraction force of each other. When such coalescence and aggregation accelerate, the particle size becomes very large while affecting the stability. However, when looking at the particle picture of Figures 11 to 26, it can be seen that the particle size according to the change over time is uniform, showing a very stable form.

Experimental Example  1-3: Degree of acceptance  evaluation

The calcium content was fixed at 30% by weight, and the content of the surfactant and the solvent was adjusted to prepare the non-interfacial calcium of Examples 17 to 19 with the compositions shown in Table 6, and 10% by weight of each composition sample was 90%. After sealing in a round flask containing weight percent purified water and sealing it for 30 minutes at 70 ° C. using a magnetic stirrer, the degree of solubility (swelling of calcium) was evaluated using a 100 ml measuring cylinder.

The results are shown in Table 8 and FIG. 11. As a result of the evaluation, it was found that the degree of solubility was different according to the phospholipid (PC) content of lecithin. However, in the case of 75% and 80% of phospholipids, the difference in solubility was not large even after repeated experiments. Therefore, if the content of phospholipids of lecithin is 75% or more, it can be easily applied to the product. Could.

The moisture content was measured as in Table 9 below. Through the above experiments, it has been found that the solvent such as dipropylene glycol and ethanol easily exits from the water and plays a role as a mixing aid for mixing and mixing the poorly soluble materials.
