Technical Field

[0001] This invention belongs to the medical field, specifically relating to a selenium-containing compound vitamin chewable tablet and its preparation method. Background Technology

[0002] Vitamins are a collective term for a series of organic compounds. They are a class of trace organic substances essential for humans and animals to maintain normal physiological functions. Most cannot be produced by the organism itself and must be obtained from food; only a few can be synthesized in the body or produced by intestinal microorganisms. Trace elements are important substances for human growth and development, enhancing physical strength, and maintaining health. They are usually ingested through food. Selenium is an indispensable trace element for human life activities. It is an essential component of various selenium-containing enzymes and proteins in the human body, such as thioreductase, deiodinase, and glutathione peroxidase, participating in various metabolic processes. Selenium deficiency can lead to a decline in the body's immune function.

[0003] However, as a major agricultural country since ancient times, my country's diet has been primarily plant-based, resulting in a relatively monotonous dietary structure and a serious imbalance in the intake of trace elements and vitamins. Currently, there are many pharmaceutical and health food products available to supplement vitamins and trace elements, such as chewable tablets. Multivitamin complex products are the preferred choice for consumers due to their comprehensive vitamin content. However, the taste and stability of current vitamin chewable tablets are still unsatisfactory, therefore further research is needed on selenium-containing multivitamin chewable tablets.

[0037] Comparative Example 4 The difference between this comparative example and Example 1 is that the step of citrus fiber pretreatment is omitted.

[0038] Experimental Example 1: Cytotoxicity Experiment Mouse fibroblasts were collected and cultured in DMEM / F12 medium containing 10% FBS, 100 U / mL penicillin, and 100 μg / mL streptomycin in a 37°C, 5% CO2 cell culture incubator. When the mouse fibroblasts reached 70% confluence, they were digested with 0.25% trypsin, centrifuged at 1600 rpm for 5 min, resuspended, and counted. The cell density was adjusted to 5 × 10⁶ cells / mL.4 Cells were seeded at 100 μL / well in 96-well plates. The original culture medium was aspirated from the 96-well plates, and 100 μL of DMEM / F12 medium containing modified silica (10% FBS, 100 U / mL penicillin, 100 μg / mL streptomycin, and 100 μg / mL modified silica prepared in Example 1) was added. The plates were cultured for 24 h as the experimental group. A control group was also set up; the original culture medium was aspirated from the 96-well plates, and DMEM / F12 medium (containing 10% FBS, 100 U / mL penicillin, and 100 μg / mL streptomycin) was added. The plates were cultured for 24 h. The medium was then replaced with 100 μL of live / dead staining solution (AM:PI: medium = 1:1:1000). After staining for 15 min, the fibroblast status was observed using a fluorescence microscope. Live cells were stained green, as shown in the results below. Figure 2 , Figure 3 As shown (magnification × 100). From Figure 2 , Figure 3 It is evident that the cell morphology of the experimental group and the control group is similar, which is the normal morphology of mouse fibroblasts. This indicates that the modified silica prepared in Example 1 did not damage the morphology of mouse fibroblasts and is safe.

[0039] Example 2: Evaluation of Physicochemical Properties According to the determination methods and standards of Part IV of the 2020 edition of the Pharmacopoeia of the People's Republic of China, the hardness of the selenium-containing compound vitamin chewable tablets obtained in Examples 1-3 and Comparative Examples 1-4 was determined, and the results are shown in Table 1.

[0040] Table 1 As shown in Table 1, the chewable tablets of Examples 1-3 of this invention have a moderate hardness compared to Comparative Examples 1-4, resulting in better palatability, stability, and ease of carrying and storage. Specifically, this invention adds acetylated distarch adipate to the raw material components. Acetylated distarch adipate is a modified starch with good stability and mouthfeel, increasing the hardness of the chewable tablets and preventing them from crumbling during chewing. This invention also adds sodium octenyl succinate starch to the raw material components, improving the mouthfeel of the chewable tablets, making them more delicate and smooth. This invention uses acetylated distarch adipate and sodium octenyl succinate starch in combination to improve the crispness of the chewable tablets, eliminating any gritty feeling and enhancing palatability. Chewable tablets with lower hardness, besides having a poor mouthfeel, are also prone to breakage, deformation, or scattering during packaging, transportation, and storage, failing to maintain their integrity. This exposes the drug components to the air, making them susceptible to the effects of light, humidity, oxygen, etc., accelerating drug degradation and deterioration, leading to drug component loss or contamination risks.

[0041] Experimental Example 3 Stability Evaluation 1. The selenium-containing multivitamin chewable tablets obtained in Examples 1-3 and Comparative Examples 1-4 were placed in a constant temperature and humidity container (saturated sodium chloride aqueous solution) at a temperature of 28°C and a relative humidity of 75%. The weight gain rate (%) of the selenium-containing multivitamin chewable tablets was measured after 7 days. The results are shown in Table 2.

[0042] 2. The L-ascorbic acid content of the selenium-containing compound vitamin chewable tablets obtained in Examples 1-3 and Comparative Examples 1-4 was determined according to the determination methods and standards in Part II of the 2020 edition of the Pharmacopoeia of the People's Republic of China. The degradation rate (%) of L-ascorbic acid after storage for 3 months at a temperature of 37°C and a relative humidity of 75% was calculated. The results are shown in Table 2.

[0043] Table 2 As shown in Table 2, Examples 1-3 of the present invention exhibit superior stability compared to Comparative Examples 1-4. Specifically, the present invention incorporates modified silica in the raw material components, which possesses excellent flowability and compressibility. The increased specific surface area of ​​the modified silica enhances its adsorption capacity, providing more adsorption sites for the active ingredients, effectively reducing vitamin attenuation, and improving the stability of the components.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. The basic principles and main features of the present invention have been described above with specific implementation schemes. Based on the present invention, some modifications or substitutions can be made, but these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of protection claimed by the present invention.
