Description

[0001] This application claims priority to the earlier application filed on September 22, 2023 with China National Intellectual Property Administration, patent application number 202311227319.3, entitled "An iripepiperazole oral film, its preparation method and application". Technical Field

[0002] This invention relates to a birepiperazole oral film, its preparation method, and its application. Background Technology

[0003] REXULTI (brand name: iriperazole) was jointly developed by Otsuka Pharmaceutical Co., Ltd. of Japan and Lundbeck Pharmaceutical Ltd. of Denmark. It was approved by the FDA in July 2015. The dosage form is tablets, with strengths of 0.25mg, 0.5mg, 1mg, 2mg, 3mg and 4mg.

[0004] Iripiparazole tablets, as a 5-HT1A receptor and dopamine D2 receptor agonist and a 5-HT2A receptor antagonist, are clinically used to treat major depressive disorder and schizophrenia. For the treatment of major depressive disorder, the starting dose is 0.5 mg / day or 1 mg / day, then increased to a target dose of 2 mg once daily, with a maximum recommended dose of 3 mg / day. For the treatment of schizophrenia, the starting dose is 1 mg / day, with a recommended target dose of 2 to 4 mg once daily, and a maximum recommended dose of 4 mg / day. Iripiparazole has broad activity across multiple monoamine systems, exhibiting decreased activity against some dopamine D2 receptor agonists and increased affinity for specific 5-HT receptors (such as 5-HT1A, 5-HT2A, and 5-HT7), resulting in better efficacy and tolerability, and reducing adverse reactions such as akathisia, restlessness, or insomnia.

[0005] Buripiperazole (7-[4-(4-benzo[B]thiophene-4-yl-1-piperazine)butoxy]-2(1H)-quinolinone) is a white or off-white crystalline powder that is almost insoluble in water and has a bitter and numbing irritant effect, which can cause significant irritation to the oral mucosa.

[0006] Iripiparazole tablets must disintegrate in the stomach before releasing the drug, resulting in a slow onset of action and limiting bioavailability. They are also inconvenient to take; as a treatment for mental illnesses, patients with this indication often have poor adherence to treatment, frequently refusing treatment, hiding medication, or vomiting. Patent document CN105078910A discloses a method for preparing iripiparazole orally disintegrating tablets, using lyophilization technology to prepare lyophilized orally disintegrating tablets containing iripiparazole, thus accelerating disintegration and improving dissolution. However, this technology is relatively cumbersome, requiring specialized equipment for production, resulting in high product costs. Furthermore, the prepared formulation is easily broken, making it unsuitable for transportation and increasing packaging and shipping difficulties. Additionally, the tablets must not come into contact with water before administration, increasing the demands on patients and negatively impacting compliance in patients with schizophrenia.

[0007] Patent document CN105395528A discloses an iripepiazole oral instant film. However, because iripepiazole is almost insoluble in water, it is difficult to disperse in a hydrophilic adhesive. During the coating and drying process, the drug is prone to agglomeration, thus affecting the uniformity of the active ingredient content. Furthermore, patients may experience unpleasant taste after taking it, affecting compliance.

[0008] Therefore, there is an urgent need to develop formulations of biriperazole that are convenient to take, stable in nature, have good patient compliance, high bioavailability, and / or suitable for industrial production. Summary of the Invention

[0063] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. It should be understood that the following embodiments are merely illustrative and explanatory of the present invention, and should not be construed as limiting the scope of protection of the present invention. All technologies implemented based on the above content of the present invention are covered within the scope of protection intended by the present invention.

[0064] Unless otherwise stated, the raw materials and reagents used in the following examples are commercially available products, or can be prepared by known methods, or selected according to the product instructions.

[0065] Examples 1-10: The prescriptions are shown below (% in the table represents weight percentage).

[0066]

[0067]

[0068] Purified water * As a solvent and wetting agent, it is removed during the process.

[0069] Preparation method:

[0070] 1) Dissolve water-soluble excipients such as plasticizers, sweeteners, and disintegrants in purified water, and then add the film-forming material to dissolve it;

[0071] 2) Mix the insoluble excipients in the prescription with the solution obtained in step 1) to obtain a suspension;

[0072] 3) Add the active ingredient to the solution obtained in step 2) and mix well;

[0073] 4) Defoam the suspension obtained in step 3) to obtain a defoamed suspension;

[0074] 5) The defoamed suspension obtained in step 4) is coated onto the substrate, dried, and a film is formed to obtain bripiprazole oral film.

[0075] Comparative Examples 1-3

[0076] Comparative Example 1 was prepared by repeating Example 4 of the invention patent application CN115192549A; Comparative Example 2 was prepared by replacing the dimethyl silicone oil in Comparative Example 1 with glycerin. The formulations are shown below (% in the table are weight percentages).

[0077]

[0078] Purified water * As a solvent and wetting agent, it is removed during the process.

[0079] During the preparation of Comparative Example 1, it was found that after adding dimethyl silicone oil to the formulation (Comparative Example 1), the drug film would peel off from the substrate on its own during the drying process. Since the small-scale test was carried out by manual cutting, no problem was observed. However, after the formulation was transferred to large equipment, it was found that due to the peeling problem, Comparative Example 1 could not be accurately cut and packaged, which was not conducive to mass production.

[0080] However, in Comparative Example 2, replacing dimethyl silicone oil with glycerin effectively avoided the aforementioned problems.

[0081] The applicant replicated the preparation of Comparative Example 3 in Example 5 of the invention patent CN115192549A: the prescription is as shown above (% in the table is weight percentage), and the prescription was prepared using the process in CN115192549A and the process of the present invention.

[0082] The results showed that in CN115192549A, bripiprazole and the film-forming material dissolved simultaneously. When the bripiprazole particle size was too large, film formation occurred during the dissolution of the film-forming material, causing bripiprazole to be trapped in the film-forming matrix, which was not conducive to dispersion. 90When the particle size is >30 μm, the uniformity of the adhesive mixture is poor. However, this invention optimizes the process by first dissolving the film-forming material and then adding bripiprazole. Under the action of a high-speed shear press, bripiprazole can be well dispersed, thus achieving a higher concentration of bripiprazole D. 90 Even at a size greater than 30 μm, qualified finished products can still be prepared.

[0083] Test case

[0089] The thickness and width of the oral solution membrane were measured using a thickness gauge and a ruler, and the cross-sectional area of ​​the oral solution membrane (mm²) was calculated. 2 );

[0090] After the thickness and width of the oral slurry membrane have been measured, fix it on the texture analyzer, making the cross-section to be measured perpendicular to the stretching direction of the equipment, and record the maximum force and sample height.

[0091] Tensile strength (MPa) = maximum force (gf) ÷ 10² ÷ cross-sectional area (mm²) 2 );

[0092] Percentage elongation = maximum force distance (mm) ÷ sample height (mm) × 100%.

[0093] Folding endurance: the number of times a folded membrane breaks or shows obvious creases after being folded in the same position; specifically, fold it 180° along the middle of the oral fusion membrane, unfold it, and then repeat the folding to observe whether the oral fusion membrane breaks.

[0094] Buripiperazole oral films were prepared according to Examples 1-10 and Comparative Examples 2 and 3.

[0136] Based on the above experimental data, it can be seen that the birepiperazole oral disintegrating film composition provided by the present invention has the advantages of thin thickness, rapid disintegration, stable properties, good mechanical properties, and instantaneous dissolution in the oral cavity without the need for drinking water, and rapid oral absorption.

[0137] This invention overcomes the shortcomings of existing technologies, such as the requirement that ibuprofen tablets must disintegrate in the stomach before releasing the drug, resulting in slow onset of action, limited bioavailability, inconvenience of administration, and poor patient compliance. It provides an ibuprofen oral film formulation, its preparation method, and its application. This ibuprofen oral film formulation has the advantages of being thin, having a good taste, stable properties, and dissolving instantly in the mouth without the need for water, resulting in rapid oral absorption. Furthermore, it features a simple process, high drug loading capacity, and good drug content uniformity, solving the problems of poor medication compliance, drug stagnation, and vomiting in schizophrenia patients. It is particularly suitable for patients with swallowing difficulties.

[0138] The embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
