Description

A colchicine film agent

[0001] Cross-references to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410799980.X, filed on June 20, 2024, entitled “A Colchicine Film Agent”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the technical field of orally dissolving films, and more specifically, to a colchicine film agent. Background Technology

[0004] Oral thin film (OTF) is a novel oral drug delivery system, also known as oral dissolving film, oral dispersible film, oral fast-dissolving film, oral fast-dissolving film, and tongue film, etc. It is a film-like preparation made by processing raw drug and suitable film-forming materials.

[0005] When used, the orally dissolving film is placed on the tongue. The film is moistened by saliva and dissolves rapidly, releasing the medication, which can be absorbed through the mucous membrane or gastrointestinal tract. As a novel oral dosage form, orally dissolving films have the following advantages compared to existing tablets, capsules, or oral solutions: ① The orally dissolving film dissolves rapidly in the oral cavity, allowing the medication to quickly enter the bloodstream through the oral mucosa, resulting in rapid onset of action; ② The release rate of the drug can be controlled, ensuring stable drug release; ③ The dosage of the drug in the orally dissolving film can be precisely controlled, reducing drug waste and improving therapeutic efficacy; ④ It does not require water to take, and its small size and light weight make it convenient for patients to use in any situation. Therefore, orally dissolving films have the advantages of rapid absorption, efficient release, accurate dosage, and ease of use.

[0006] Currently, the oral dissolving film formulations approved for marketing in my country include memantine hydrochloride oral dissolving film, aripiprazole oral dissolving film, ondansetron oral dissolving film, tadalafil oral dissolving film, montelukast sodium oral dissolving film, and olanzapine oral dissolving film. Therefore, the variety of oral dissolving film formulations researched in my country is relatively limited. Furthermore, the research on oral dissolving film formulations is not yet fully developed, and different products exhibit varying film-forming properties and tear-off characteristics.

[0007] Gout is a disease caused by excessive uric acid deposition. During an acute gout attack, early anti-inflammatory and analgesic treatment is recommended (generally within 24 hours). Colchicine is effective in reducing inflammation and pain, improving patients' quality of life. However, excessive use of colchicine can cause toxic side effects. Common adverse reactions include nausea, vomiting, diarrhea, abdominal pain, and gastrointestinal reactions; in severe cases, it can prevent patients from adhering to medication regimens. Currently, colchicine is generally available in tablet or oral liquid form, which is highly irritating to the intestines. There is little record of colchicine film formulation preparation.

[0008] Given the significant differences in the required dosage of colchicine for treating familial Mediterranean fever (FMF) and gout, and the relatively low dosage required for FMF treatment, current tablet formulations are limited by the difficulty in accurately dispensing whole tablets, making it difficult to meet the needs of low-dose individualized treatment. Furthermore, colchicine, as a highly active drug, has an extremely narrow therapeutic window, with the therapeutic dose being very close to the toxic dose, requiring extremely high accuracy in dosage dispensing. Traditional oral tablets have significant shortcomings in dosage adjustment, easily leading to dosage errors and increasing medication risks. Therefore, developing a colchicine oral instant-dissolving film with rapid dissolution characteristics and good dispensing operability has significant clinical application prospects and is urgently needed. However, there are no reports in this field regarding the film-forming properties, flexibility, and tearability of colchicine films. Summary of the Invention

[0009] This application aims to overcome at least one of the defects of the prior art and provide a colchicine film that is easy to take, has a rapid onset of action, and is less irritating to the intestines; and / or the colchicine film provided by this application can achieve good flexibility, and / or film-forming properties and / or easy tearing, meeting the needs for good dispensing operability and precise drug delivery.

[0119] The effects of the colchicine film obtained in Examples 1-30 were tested, and the film-forming properties, flexibility and tearability were examined.

[0120] Experimental Example 1: Content Uniformity

[0121] Content uniformity refers to the degree of uniformity of the active ingredient contained in each dosage unit of a pharmaceutical preparation. Colchicine film formulations are low-dose preparations with high requirements for formulation composition, and their content uniformity reflects film-forming performance.

[0122] Experimental methods and instruments

[0123] 1) Instrument: High Performance Liquid Chromatograph (Manufacturer: Shimadzu, Model: LC2010)

[0124] 2) Experimental methods:

[0125] For the film preparations of Examples 1-29, 10 films were randomly selected from each example, each approximately 60 mg. The weight of each film was accurately recorded, and the films were transferred to 25 mL volumetric flasks. A methanol-water solution (methanol:water = 20:80) was added to approximately half the volumetric flask. The flasks were then sonicated for 10 minutes under ice pack cooling, with manual shaking performed periodically. After sonication, the solution temperature was allowed to equilibrate to room temperature, and then diluted to the mark with diluent and mixed thoroughly. The solution was then filtered through a 0.45 μm nylon membrane. The first 3 mL of filtrate was discarded, and the subsequent filtrate was collected. After centrifugation, the clear supernatant was collected and used for HPLC detection to determine the content. The RSD of the content was calculated and recorded. The results are shown in Table 8.

[0127] Experimental Example 2: Flexural Strength Test

[0128] A mechanical stress test method based on repeated folding to fracture was used to evaluate the flexibility of colchicine film, reflecting its ductility and fatigue resistance.

[0129] Experimental methods:

[0130] The membrane formulations prepared in Examples 1-30 were each cut into standard test samples with a size of 1 inch × 1 inch. Each sample was folded longitudinally along one side of the center line, and then continuously folded in the opposite direction until the membrane broke mechanically. Six independent samples (n=6) were tested for each membrane formulation, and the number of folds that each membrane could withstand before breaking was recorded, and the average number of folds was recorded. The results are shown in Table 9.

[0131] Table 9

[0132] Actual test data shows that the number of folds for different formulations of the film varies from more than 2 to 150 times.

[0133] Experiment Example 3 Tearability Test

[0134] Experimental methods and instruments

[0135] 1) Instrument: Intelligent electronic tensile testing machine (Manufacturer: Jinan Langguang Electromechanical Technology Co., Ltd., Model: C610M)

[0136] 2) Experimental methods:

[0137] The membrane formulations prepared in Examples 1-29 were each cut into standard test samples with a size of 1 inch × 1 inch. A centerline tear line was rolled onto each sample, corresponding to the center of one side and the center of the parallel side. The two ends of the sample were clamped in the upper and lower jigs of a tensile testing machine. The test type was set to tensile strength and deformation rate test, and the jig separation speed was 10 mm / min. The testing machine was started, and the test ended when the sample was completely torn in half. Three independent samples (n=3) were measured in parallel for each membrane formulation, and the average value of the maximum tear force and the average value of the displacement were recorded. The results are shown in Table 10.
