The pharmaceutical compositions of the present invention can have any pH within the aforementioned specific range, i.e., pH values without the prefix "about".
[0034] I. Definition
[0035] The term "the active pharmaceutical ingredient of Formula I" may also be referred to as "compound 1" or "this compound". Similarly, "a salt of the active pharmaceutical ingredient of Formula I" may also be referred to as "a salt of compound 1" or "a salt of this compound". For example, an active pharmaceutical ingredient of Formula I in hydrochloride form may be referred to as "the hydrochloride salt of compound 1" or "the hydrochloride salt of this compound".
[0036] In this specification, a "pharmaceutically acceptable salt" may be prepared by any suitable method available in the art, for example, by treating the pharmaceutically active ingredient of Formula I in its free base form with an inorganic acid. Examples of effective inorganic acids include, but are not limited to, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, methanesulfonic acid, phosphoric acid, etc., or include organic acids such as acetic acid, trifluoroacetic acid, maleic acid, succinic acid, mandelic acid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolic acid, salicylic acid, glucuronic acid or galacturonic acid and other pyranoside acids, α-hydroxy acids such as citric acid or tartaric acid, amino acids such as aspartic acid or glutamic acid, aromatic acids such as benzoic acid or cinnamic acid, sulfonic acids such as p-toluenesulfonic acid or ethanesulfonic acid, etc. Most preferably is the hydrochloride salt of the pharmaceutically active ingredient of Formula I.
[0037] In this specification, "pharmaceuticalally acceptable carrier" refers to a non-toxic carrier, excipient, or loading agent that does not impair the pharmacological activity of the formulated compound. Pharmaceutically acceptable carriers, excipients, or loading agents that can be used in the compositions described herein include, but are not limited to, ion exchangers, alumina, aluminum stearate, buffers (e.g., phosphates), glycine, sorbic acid, potassium sorbate, mixtures of saturated vegetable fatty acids in the form of glycerides, water, salts or electrolytes (e.g., protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts), colloidal silica, magnesium trisilicate, polyvinylpyrrolidone, cellulose, polyethylene glycol, sodium carboxymethyl cellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol, and lanolin.
[0038] In this specification, the terms "stable" and "stable" mean that the pharmaceutical composition is stable to, for example, heat, light, temperature, and / or humidity. For example, a pharmaceutical composition is stable when the amount of total impurities included in the pharmaceutical composition of the present invention or the amount of M1 impurities of the active ingredient ("M1 impurities") is a specific percentage or lower after the pharmaceutical composition has been stored under specific conditions. M1 impurities are any inactive form of the active ingredient, such as synthetic intermediates, metabolic intermediates, byproducts, or degradation products of the active ingredient.
[0039] Total impurities, as measured by HPLC, can be defined as having a relative retention time (RRT) of about 0.11 to 2.10 relative to the peak of compound 1, more specifically, about 0.90, about 1.12, about 1.35, or about 1.38. Impurity M1 can be defined as having an RRT of about 0.90 relative to the peak of compound 1. As is known in the art, HPLC RRT values can have an experimental error of ±10% of the displayed value. In conclusion, the values described above should be interpreted in light of experimental error.
[0040] In this specification, the term "subject" intended for application includes, but is not limited to, humans (i.e., men or women of any age group, such as pediatric subjects (e.g., infants, children, adolescents) or adult subjects (e.g., young adults, middle-aged adults, or older adults)). In certain embodiments, the subject is a human. In certain embodiments, the subject is a non-human animal. In this specification, the terms "person," "patient," and "subject" are used interchangeably.
[0041] In this specification, the terms “cured,” “therapeutic,” and “treatment” refer to actions that reduce symptoms, severity of impairment, or progression of a condition, disorder, or state that occur in a subject, or delay the progression of the condition, disorder, or state (“therapeutic treatment”), or actions that occur before a subject suffers from a particular disease, disorder, or state (“preventive treatment”), unless otherwise stated.
[0042] In this specification, a "therapeuticly effective amount" of a compound means an amount sufficient to provide therapeutic benefit in the treatment of a disease, disorder, or condition, or to delay or minimize at least one symptom of the disease, disorder, or condition, unless otherwise stated. A therapeutically effective amount of a compound refers to the amount of a therapeutic agent, alone or in combination with other therapies, that provides therapeutic benefit in the treatment of a disease, disorder, or condition. The term "therapeuticly effective amount" may include amounts that improve overall therapy, reduce or prevent symptoms or causes of a disease or condition, or enhance the therapeutic efficacy of other therapeutic agents.
[0043] In this specification, the term "about" will be understood by those skilled in the art and varies depending on the context in which it is used. When a term is unclear to those skilled in the art, "about" means a maximum of ±10% of the specific term, taking into account the context in which it is used. For pH values, the term "about" means a maximum of ±0.5% of the pH value.
[0044] In this specification, "analysis" refers to a specific stability representation procedure for determining the content of a pharmaceutical substance. For example, an analysis may include chromatographic methods (e.g., HPLC) using reference standards.
[0045] In this specification, "crystal" refers to a solid with a highly regular chemical structure, that is, a solid with a long-range structural order in a crystal lattice. Molecules are arranged in a regular, periodic manner in the three-dimensional space of the crystal lattice. In particular, crystalline forms can be generated in one or more single-crystal forms.
[0046] In this specification, "excipient" means a pharmaceutically acceptable inactive ingredient commonly used in the preparation of pharmaceutical formulations. Examples of suitable excipients can be found in Sheskey et al., Handbook of Pharmaceutical Excipients, 8th Edition, written (Pharmaceutical Press 2017), which is incorporated herein by reference in its entirety. Excipients can be classified according to their functional properties as, for example, diluents, binders, disintegrants, superdisintegrants, lubricants, pH controllers, glidants, fillers, stabilizers, antioxidants, and film-coating agents. However, as is known in the art, a particular excipient can be classified into at least one of the functional groups listed above, depending on the time and manner of use. For example, an excipient may be classified as a disintegrant in one formulation and as a binder in another. In some cases, a particular excipient may be multifunctional, i.e., classified into one or more functional groups in the same formulation. The considerations that are typically required when formulating and / or preparing pharmaceutical compositions are described, for example, in Remington's Pharmaceutical Sciences, 16th edition, EW Martin (Mack Publishing Co., Easton, PA, 1980) and Remington: The Science and Practice of Pharmacy, 21st edition (Lippincott Williams & Wilkins, 2005), which are incorporated herein by reference in their entirety.
[0047] In this specification, "binder" refers to an excipient that imparts enhanced cohesiveness or tensile strength (e.g., hardness) to a pharmaceutical composition. Examples of binders include dicalcium phosphate, sucrose, corn starch, microcrystalline cellulose, and modified cellulose (e.g., hydroxymethyl cellulose).
[0048] In this specification, "diluent" refers to an excipient that increases the volume of a pharmaceutical composition. Examples of diluents include lactose, sorbitol, cellulose, calcium phosphate, starch, sugars (e.g., mannitol, sucrose, etc.) or any combination thereof.
[0049] In this specification, "disintegrant" refers to an excipient that hydrates the pharmaceutical composition and facilitates tablet dispersion. Examples of disintegrants include croscarmellose sodium and / or starch glycolate sodium.
[0050] In this specification, "lubricant" refers to an excipient added to a pharmaceutical composition compressed into tablets. The lubricant facilitates the expulsion of the tablet composition from the molding machine after the granules are compressed into tablets. Examples of lubricants include magnesium stearate, stearic acid (stear), hydrogenated oil, sodium stearate fumarate, or any combination thereof.

When CMC-Na is used (sample 11), the impurity content also increases, and an additional pH control agent may be used to improve the stability of the pharmaceutical composition.
[0080] As long as the desired pH range is achieved, any combination of pH control agents or pH agonists known in the field can be used.
[0081] In a preferred embodiment, the pH control agent used in this invention may be a pH control agent having a pH of about 1 to about 5, preferably about 1.5 to about 3, and more preferably about 2 to about 2.5. The pH of the pH control agent is defined as the pH of the solution or suspension obtained when the pH control agent is dissolved or suspended in water at a concentration of 1% w / v.

[0109] (a) Premixing an excipient comprising part or most of the active ingredient and binder in a mixer to obtain a premix;
[0110] (b) The premixture of step (a) is granulated by adding a granulation liquid (preferably purified water);
[0111] (c) Dry the particles from step (b) in a fluidized bed dryer or drying oven;
[0112] (d) Optionally, the dried particles from step (c) are dry-sieved;
[0113] (e) The dried particles, lubricant, flow aid and other excipients from step (d) are mixed in a mixer to obtain the final mixture;
[0114] (f) The final mixture from step (e) is compressed in a suitable tablet press to produce a tablet core; and
[0115] (g) Optionally, the core from step (f) may be coated with a film.
[0116] In another specific embodiment, the present invention provides a dry granulation method for preparing a pharmaceutical composition, comprising:

[0121] (e) Compressing the particles of step (c) or the final mixture of step (d) using a suitable tablet press to produce a tablet core; and
[0122] (f) Optionally, the core from step (e) may be coated with a film.
[0123] In addition, the present invention provides a pharmaceutical composition such as a tablet, which can be obtained by the following method.
[0124] Granules and microgranules can be prepared by granulation using the same methods as those used for tablets (e.g., wet or dry granulation). Alternatively, they can be prepared by spraying a coating solution comprising the active ingredient and excipients, particularly binders such as sucrose, hydroxypropyl cellulose, and hydroxypropyl methylcellulose, onto sugar spheres to form coated spheres. As described above, the granules can be wet or dry granules.
[0125] Capsules are prepared by filling capsules made of gelatin such as hydroxypropyl methylcellulose with granules or microparticles, or by filling capsules made of gelatin such as hydroxypropyl methylcellulose with active ingredients and excipients (e.g., lactose, sucrose, glucose, starch, sugars, microcrystalline cellulose, licorice powder, mannitol, sodium bicarbonate, calcium phosphate, calcium sulfate, etc.).

[0141] Experimental Example 1: Stability of tablets from samples 1 to 9 relative to different pH values
[0142] The hydrochloride salt and excipients of this compound were mixed according to the formulation in Table 1 below and then compressed to prepare uncoated tablets. Each tablet was placed in triple-distilled water to achieve a tablet concentration of 1% w / v (weight / volume) and stirred at 1200 rpm for 5 minutes at room temperature using a magnetic stir bar to form an aqueous suspension (referred to as the "1% w / v aqueous suspension"). After the suspension was allowed to stand for 5 minutes, the pH of the suspension was measured at room temperature using a Mettler Toledo S20 SevenEasy pH meter. The pH of each tablet prepared from samples 1 to 9 was measured, and the results are shown in Table 1 below.
[0143] In addition, the stability of the tablets prepared in Examples 1 to 9 was evaluated. Each tablet was stored for 2 and 4 weeks in HDPE bottles sealed with a desiccant (silica gel) at 50°C and 75% RH (relative humidity). The M1 impurity content (%) and total impurity content (%) of each tablet were then determined by HPLC.
[0144] HPLC analysis was performed using a C18 column (4.6 mm × 15 cm; 5 μm) on a detector with UVmax set to or close to 280 nm. The mobile phase was a mixture of purified water and formic acid or a mixture of methanol and formic acid. The M1 impurity content (%) and total impurity content (%) were analyzed at the initial date (0 days), 2 weeks, and 4 weeks. The impurity content (%) was calculated as follows.
[0145] M1 impurity content (%) = (peak area of M1 impurity in the sample / total peak area of the sample) × 100
[0146] Total impurity content (%) = (sum of peak areas of all impurities in the sample / total peak area of the sample) × 100
[0147] The results are shown in Table 1 below.
[0148] [Table 1]
[0149]
[0150]
[0151] ※ND: Not confirmed
[0152] The pharmaceutical compositions (samples 1 to 8) containing the hydrochloride salt of this compound at pH values from about pH 2.6 to pH 6.48 have demonstrated significant stability with low impurity content after prolonged storage. They are particularly stable near pH 3.0 (samples 3 and 7). Conversely, when the pH is greater than 7.0, impurities increase sharply, and stability decreases (sample 9).
[0153] Therefore, the compounds of the present invention are confirmed to be stable in the pH range of 2.6 to 6.48.
[0154] Experimental Example 2: Stability of tablets of samples 2, 10 to 21 relative to different excipients
[0155] Based on the preparation method described in samples 1 to 9, the hydrochloride salt of this compound and each additive were mixed according to the formulations in Tables 2 and 3 below and then compressed into tablets to prepare unprocessed tablets.
[0156] The pH of each tablet prepared in samples 2, 10 to 21 was measured in the same manner as in Experimental Example 1, and the results are shown in Tables 2 and 3 below.
[0157] Stability evaluations were performed on tablets prepared from samples 2, 10 to 21 containing other excipients. After storage at 50°C and 75% RH for one week in the unsealed state, the impurity (M1) content (%) in each tablet was measured by HPLC according to the method described in Experimental Example 1. The results are shown in Tables 2 and 3.
[0158] Samples 2, 10 to 17
[0159] [Table 2]
[0160]
[0161]
[0162] ※BRT (below reporting threshold)
[0163] The above results confirm that tablets of samples 2, 10, 12 to 17 exhibited excellent stability, while tablet of sample 11 showed low stability. In sample 11, CMC-Na was used as a disintegrant, which was determined to increase the overall pH of the tablet, thereby reducing the stability of the active ingredient.
[0164] Samples 18 to 21
[0165] [Table 3]
[0166]
[0167]
[0168] ※ND: Not confirmed
[0169] Sample 21 provided the best stability results. The stability of samples 18 to 20 was lower than that of sample 21 due to the increased M1 impurity; however, samples 18 to 19 (and 21) still showed less than 0.50% of M1 impurity, which was below the desired level. Sample 20 was an exception.
[0170] Experimental Example 3: Stability of tablets of samples 22 to 33 relative to various excipients
[0171] Based on the preparation methods described in samples 1 to 9, the hydrochloride salt of this compound and each additive were mixed according to the formulation in Table 4 below and then compressed into tablets to prepare unprocessed tablets.
[0172] The pH of each tablet prepared in samples 22 and 33 was measured in the same manner as in Experimental Example 1, and the results are shown in Table 4 below.
[0173] Stability evaluations were performed on tablets prepared from samples 22 to 33 containing different excipients. After storage in a closed state at 50°C for 2 and 4 weeks without adjusting the RH of each tablet, the M1 impurity content (%) and total impurity content (%) of each tablet were determined according to the HP LC method described in Experimental Example 1. The results are shown in Table 4 below.
[0174] [Table 4]
[0175]
[0176]
[0177] ※ND: Not confirmed
[0178] The above results confirm the improved stability of the compositions of the present invention at pH values ranging from 2.8 to 6.55. In fact, all samples except sample 28 were stable. In particular, samples 23, 25, 27, 29, 31, and 33, whose pH was adjusted to approximately 3 using a pH control agent, exhibited significantly improved stability.
[0179] Experimental Example 4: Stability of film-coated sheets based on excipients, samples 34 to 36
[0180] Based on the preparation methods described in samples 1 to 9, the hydrochloride salt of this compound and each additive were mixed according to the formulations in Table 5 below and then compressed to prepare tablets (ordinary). Membrane coating was performed to prepare membrane-coated sheets of samples 34 to 36.
[0181] The stability of the tablets prepared in samples 34 to 36 was evaluated. Each tablet was encapsulated in Alu-Alu at 40°C and 75% RH and stored in a sealed state for 3 and 6 months. The M1 impurity content (%) and total impurity content (%) were measured by HPLC as described in Example 1. The results are shown in Table 5.
[0182] [Table 5]
[0183]
[0184]
[0185] The stability of the pharmaceutical composition comprising the active pharmaceutical ingredient of Formula I or a pharmaceutically acceptable salt thereof and a coating film of at least one pharmaceutically acceptable excipient was demonstrated when the pH of the composition was measured to be from about 2.6 to about 6.74 in a 1% w / v aqueous suspension prepared according to Experimental Example 1.
