Description

Disintegrable solid composition and orally disintegrable solid preparation
The present application claims the priority of prior applications of patent application nos. CN202110374537.4 and CN202110503420.1, which were filed in the intellectual property office of china at 2021, 04, 07 and 2021, 05, 10, respectively, and the names of the invention are "disintegrating composition and orally disintegrating solid preparation". The entire contents of said prior application are incorporated by reference into the present application.
Technical Field
The invention belongs to the technical field of pharmaceutical preparations, and particularly relates to a disintegrating solid composition and an oral disintegrating solid preparation.
Background
Disintegrating tablets disintegrate readily in the body (e.g. in the mouth) after administration. If the orally disintegrating tablet is administered orally, it is generally desirable that the disintegration time in the oral cavity is within 1 to 30 seconds without chewing. Orally disintegrating tablets are very valuable tablets for the user, especially for persons with poor swallowing abilities, such as infants and adults, because these tablets can be taken without water.
There is a need for a formulation for such tablets that retains its shape during handling and undergoes minimal crushing and breakage. Therefore, one aspect of pharmaceutical research on tablets is the need for increased hardness. However, if only high hardness is provided, it is impossible to obtain the intended use as a pharmaceutical preparation, because this may result in degradation or denaturation of the active ingredient or change in the function of the functional particles. However, compression molding under high pressure while the hardness is sought after is generally increased, but actually there are many inconveniences in manufacturing pharmaceutical preparations due to the increase in compression molding pressure. For example, many physiologically active ingredients are known to lose activity when compression molded under high pressure.
Therefore, development of tablets is required to ensure that the hardness of the tablets themselves is sufficiently high to prevent functional changes of functional particles due to compression, and to have an appropriate oral disintegration time. In addition, with respect to orally disintegrating tablets, it is further considered whether or not there is a noticeable foreign body sensation in the oral cavity, and the like.

The words "preferred", "preferably", "more preferred", and the like, in the present invention, refer to embodiments of the invention that may provide certain benefits, under certain circumstances. However, other embodiments may be preferred, under the same or other circumstances. Furthermore, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, nor is it intended to exclude other embodiments from the scope of the invention. The sources of the components not mentioned in the present invention are all commercially available.
Unless otherwise stated, the adjuvants mentioned in the present invention, such as fillers, disintegrants, lubricants, protectants, hydrogels, etc., are pharmaceutical adjuvants and have meanings in line with the conventional meanings in the art, such as in line with the interpretation of terms in pharmacopoeia or pharmaceutical adjuvant handbooks.
The "total mass of the solid composition" in the present invention refers to the total mass of the excipients and the bioactive ingredients in the disintegrating solid composition, i.e., the dry weight after removing the solvent (e.g., water).
After earnest research to solve the problems, the inventor discovers that when the hydrophilic colloid with certain gel strength and the optimized disintegrating agent are used in combination, and particularly when the disintegrating agent is selected from L-HPC and CMC-Na, the obtained finished product is not crushed, not cracked and has no residue under the synergistic action of the L-HPC and the CMC-Na, the hardness of 8-9N and the disintegration time of about 2s can be achieved, and meanwhile, the inventor has better mouthfeel and avoids the inactivation of active ingredients.
The inventor has made intensive studies, and has considered that the feeling of grittiness in the mouth caused by the insolubility of microcrystalline cellulose and the influence of the physical properties of the effective components on the itself, which greatly affects the disintegrability of the drug; the inventors then tried to substitute starch in a solution without microcrystalline cellulose, but it is known that too high a starch content results in a tablet with poor compression formability. In the subsequent studies, the inventors have unexpectedly found that a desired disintegration property can be obtained by using a specific gelatin even without containing starch, but the hardness of a solid preparation is difficult to balance, but when the inventors used it together with a disintegrant having a certain composition after further studies, a disintegrating composition having a high hardness and an excellent disintegration time and an excellent appearance quality is unexpectedly obtained, and the composition can be used as a formulation platform for compatibility with various types of pharmaceutically active ingredients.
In a first aspect, the present invention provides a disintegrating solid composition comprising (a) a hydrocolloid having a freezing force of 120 bloom or more, (b) a disintegrant, and (c) a filler; wherein the hydrophilic colloid is selected from at least one of starch, gelatin, donkey-hide gelatin, deer-horn gelatin and peach gum, and accounts for 1-20% of the total mass of the composition.
Hydrophilic colloid with freezing force above 120 bloom >
Hydrocolloids are a class of colloids with a strong affinity for water, which include, for example, animal gums, starches, gums and proteins. Among them, examples of the animal gum include gelatin, donkey-hide gelatin, and antler gum, and examples of the gum include peach gum, konjac gum, and carrageenan.
The hydrophilic colloid suitable for the present invention is preferably at least one of starch, gelatin, donkey-hide gelatin, deer-horn gelatin, peach gum. The amount of the hydrophilic colloid is preferably 1 to 20% by weight, more preferably 2 to 10%, further preferably 2 to 8%, further preferably 5 to 8% of the total mass of the composition. When a plurality of the above-described preferred hydrocolloids are used in admixture, the total amount of the admixture generally remains the same as when used alone, and the respective mixing ratio may be any ratio. Gelatin and/or starch are the most suitable hydrocolloids for the present invention by investigation, wherein the gelatin used is an ampholyte which acts as a freeze-dried scaffold to coagulate charged microparticles into clumps.
In further studies on gelatin, the inventors have surprisingly found that by selecting gelatin of different freezing forces, tablets with appropriate disintegration times and different hardness can be obtained. Preferably, the gelatine has a freezing point of between 100 and 250 bloom, more preferably between 120 and 225 bloom, including, for example, 150 bloom, 160 bloom, 180 bloom, 200 bloom, 220 bloom, 250 bloom; among them, gelatin having a freezing force of 220 bloom is more preferable.
The term "freezing force" as used herein means a force in terms of bloomag (blumm) applied when a freezing surface containing 6.67% or 12.5% of gelatin is pressed into a cylindrical shape having a diameter of 12.7mm formed by dissolving and condensing a solution in a special freezing force test flask under a predetermined test environment for a certain period of time, and the freezing surface contains 4mm of gelatin. In one embodiment, a mixture of gelatin and starch is used as a hydrocolloid, and it is found that it is difficult to obtain a tablet with high hardness by compounding gelatin with starch with different freezing forces, because in the experiment, considering the water insolubility of starch, the taste is considered, and simultaneously the quality of starch cannot be improved to obtain better synergy with gelatin, which is a common problem in oral tablets containing starch; in addition, since the starch has poor formability due to the preparation process using lyophilization, the increased content may cause the tablet to be cracked or broken.
Further studies have found that in embodiments not comprising starch as the hydrocolloid, different adjustments to the disintegrant have an effect not only on the disintegration time but also on the hardness and the degree of residue.
< b) disintegrating agent >
The disintegrant is a substance which can cause the tablet to rapidly break into fine particles in contact with a liquid, and most of the substances have good water absorption and expansibility, thereby realizing the disintegration of the tablet.
As for the disintegrant in the present invention, it is preferable by study that the disintegrant includes at least one selected from the group consisting of microcrystalline cellulose, sodium carboxymethyl starch, low-substituted hydroxypropyl cellulose, sodium carboxymethyl cellulose, sodium croscarmellose, and crospovidone. More preferred disintegrants include low-substituted hydroxypropyl cellulose, sodium carboxymethyl cellulose, croscarmellose sodium, and crospovidone, and these preferred disintegrants may be used alone or in combination of two or more; when used alone, the amount is 0.5-15%, such as 3-12%, 1-10%, preferably 3-6% or 5-7% of the total weight of the composition, and excessive amounts of these disintegrants can cause the tablet to swell to form a water-resistant layer, which affects disintegration; when a plurality of disintegrants which are preferred as described above are used in combination, the total amount of the mixture thereof is generally kept to be the same as that when used alone, and the respective mixing ratio may be any ratio.
In a preferred embodiment, the disintegrant comprises (b 1) sodium carboxymethylcellulose and/or croscarmellose sodium; and (b 2) low-substituted hydroxypropylcellulose. It is further preferable that when the disintegrant is (b 1) sodium carboxymethylcellulose and (b 2) low-substituted hydroxypropylcellulose, in particular, (b 1): (b2) When the mass ratio of (2) to (3) is (0.6 to 5): 1, the overall performance is the best, and (0.7 to 3): 1 is more preferable, 1 to 3): 1 is further preferable, and (1 to 2): 1 is further preferable.
More preferably, the disintegrant used is (b 1) sodium carboxymethyl cellulose and (b 2) low-substituted hydroxypropyl cellulose, as compared to microcrystalline cellulose or sodium carboxymethyl cellulose alone as the disintegrant.
Among them, sodium carboxymethylcellulose is generally classified into four types, i.e., an extra-high viscosity, a medium viscosity, and a low viscosity, according to the viscosity thereof, and generally, the lower the viscosity thereof, the smaller the molecular weight thereof, and the lower the substitution degree thereof.
It has been unexpectedly found that the use of different degrees of substitution of sodium carboxymethylcellulose and gelatin in the present system has different properties, such as impact on mouthfeel and residual levels; the sodium carboxymethylcellulose with the proper substitution degree is presumed to enable the distribution of water in the network structure of the gelatin and the filler to be more uniform, the volume of ice crystals formed in the freeze-drying condensation process is smaller, and the damage influence on the microstructure of the tablet is smaller; conversely, if the degree of substitution is too low, poor water solubility will result in poor taste of the tablet.
The degree of substitution of the sodium carboxymethylcellulose of the present invention is between 0.5 and 2.5, preferably between 0.6 and 1.2, more preferably between 0.65 and 0.85, most preferably 0.7, in view of the final combination of properties of the tablet. The viscosity is 25 to 1500mpa.s, more preferably 25 to 1000mpa.s, still more preferably 25 to 800mpa.s, and for example, the viscosity is preferably any value selected from 25, 50, 100, 200, 300, 400, 500, 600, 700, and 800, or any value included in a range having any two of these values as a starting point and an ending point.
Sodium carboxymethylcellulose having the above-mentioned preferred degree of substitution of 0.6 to 0.9 is commercially available, and examples thereof include, but are not limited to, 7HF4XF PH, 7HF PH, 7H3SF PH, 7HOF PH, 7M31F PH, 7MF PH, 7M8SF PH, 7M1F PH, 7LF PH, 7L2P, and the like.
The substitution degree of the sodium carboxymethyl cellulose refers to the number of hydroxyl groups on each glucose unit which are substituted by ether groups on average, and the theoretical maximum substitution degree is 3; the viscosity of sodium carboxymethylcellulose is short for dynamic viscosity, and the unit is pascal second (Pas) or millipascal second (mpa.s), and is a sodium carboxymethylcellulose aqueous solution with the mass fraction of 2%, and is measured at 25 ℃ +/-0.2 ℃.
In the research, as the sodium carboxymethyl cellulose partially neutralizes 220 frozen gelatin molecules, intermolecular repulsion is reduced, molecular chains are not completely unfolded, and the low-substituted hydroxypropyl cellulose competes for cross-links among the gelatin molecules through the cross-links, so that the disintegration can be synergistically promoted and certain hardness is improved together with specific gelatin, and the result shows that the hardness, the disintegration time, the mouthfeel and the like are good when the mass ratio of (b 1) the sodium carboxymethyl cellulose with proper substitution degree and viscosity to (b 2) the low-substituted hydroxypropyl cellulose is (0.7-3): 1; the inventor has the surprise that the composition obtained by the disintegrant with the proportion has almost no residue on a packing material such as an aluminum-plastic blister after being peeled off, and is very suitable for preparing disintegrating tablets by a freeze-drying process.
