Abstract
Description
A composition for treating or improving depression and anxiety, its preparation method and uses. Technical Field
[0001] This invention relates to a composition for treating or improving depression and anxiety, as well as its preparation method and uses. Background Technology
[0002] Depression, a prevalent mental disorder, presents with diverse and complex symptoms, involving dysfunction in multiple aspects including emotion, cognition, and physiology. Its main manifestations include persistent low mood and loss of interest, often accompanied by slowed thinking, sleep problems, decreased executive function, and impaired social skills. In severe cases, patients may experience suicidal thoughts and behaviors. Anxiety, also known as anxiety neurosis, is characterized by intense, excessive, and persistent worry and fear, accompanied by restlessness, rapid heart rate, and difficulty sleeping. Depression and anxiety have become prevalent mood disorders internationally in recent years. Statistics show that the annual prevalence of anxiety disorders among residents aged 18 and above in my country is approximately 5.0%, with a lifetime prevalence of approximately 7.6%; while there are over 95 million people with depression, with a lifetime prevalence of approximately 6.9% and an annual incidence of approximately 3.6%. Currently, the rising incidence of depression and anxiety disorders globally is impacting both society and human health.
[0003] Currently, the treatment of mood disorders such as depression and anxiety primarily relies on medication. Antidepressants are broadly classified into two categories: classic antidepressants and novel antidepressants. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are the most common first-line antidepressants in clinical practice. In addition, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants (TCAs), and atypical antidepressants also have antidepressant effects. Although existing antidepressants play an important role in treatment, they have limitations such as slow onset of action, a high risk of relapse after discontinuation, and accompanying side effects, all of which weaken their clinical efficacy to some extent. Therefore, exploring an effective yet relatively safe treatment strategy to improve the symptoms and quality of life of patients with mood disorders such as depression and anxiety is particularly urgent and necessary.
[0004] Fish oil is an oil extracted from fish, rich in Omega-3 unsaturated fatty acids, primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and has been widely used in the medical and health fields. Currently, high-purity, high-concentration fish oil preparations have been approved for the treatment of specific diseases such as hypertriglyceridemia. Furthermore, fish oil is widely used in health supplements and functional foods due to its basic health benefits, such as maintaining cardiovascular health and aiding in memory improvement.
[0005] Although fish oil has been successfully applied in the aforementioned fields, there are currently no reports on its use in treating or improving depression and anxiety, particularly its scientific formulation with other active ingredients to develop products with clearly defined antidepressant and anti-anxiety functions. Therefore, developing a fish oil composition with proven efficacy against depression and anxiety is of great significance for enriching clinical and consumer choices. Technical issues

[0089] Example 8: Stability Study of Fish Oil Soft Capsules
[0090] 1. Influencing Factors Experiment
[0091] Fish oil soft capsules were placed under high temperature (60℃±2℃), high humidity (90%RH±5%RH / 25℃), and light (4500lx±500lx) conditions. Samples were taken at 0 days, 10 days, and 30 days to detect the content of EPA-EE and L-5-methyltetrahydrofolate calcium.
[0092] EPA-EE content determination method:
[0093] The sample was determined by gas chromatography (Chinese Pharmacopoeia 2020 Edition, Part IV, General Chapter 0521). Chromatographic conditions: quartz capillary column (Agilent DB-WAX, 0.32 mm × 30 m, 0.5 μm) with polyethylene glycol as stationary phase; initial column temperature 170 °C, held for 2 min, then increased to 240 °C at a rate of 2 °C / min, held for 8 min; injection port temperature 250 °C, detector (FID) temperature 270 °C, carrier gas nitrogen; split ratio 20:1, injection volume 1 μl. Calculation was performed using peak area according to the internal standard method.
[0094] Method for determining the content of L-5-methyltetrahydrofolate calcium:
[0095] The determination was performed according to high performance liquid chromatography (Chinese Pharmacopoeia 2020 Edition, Part IV, General Chapter 0512). Chromatographic conditions: Octadecylsilane-bonded silica gel was used as the stationary phase (Agilent ZORBAX SB-C18 4.6×250mm, 5µm column, or a column with equivalent performance); phosphate buffer was used as mobile phase A; phosphate buffer-methanol (65:35) (7.8g of sodium dihydrogen phosphate dihydrate was weighed and added to 1000ml of ultrapure water, mixed well, 650ml was taken, 350ml of methanol was added, mixed well, and the pH was adjusted to 8.0 with 32% sodium hydroxide solution) was used as mobile phase B, and gradient elution was performed according to the table below; the detection wavelength was 280nm; the flow rate was 1.1ml per minute; the column temperature was 32℃; and the injection volume was 10μl.
[0096]
[0097] The stability results are shown in Table 2.
[0098] Table 2. Stability data of fish oil soft capsules under different conditions
[0099]
[0100] 2. Long-term stability test
[0101] Fish oil soft capsules were placed at 25℃±2℃ and 60%RH±5%RH, and samples were taken at 0 days, 3 months, and 6 months. The contents of EPA-EE and L-5-methyltetrahydrofolate calcium were determined according to the detection conditions in the influencing factor test. The results are shown in Table 3.
[0102] Table 3. Long-term stability test data of fish oil soft capsules
[0103]
[0104] Fish oil is rich in Omega-3 unsaturated fatty acids, which are prone to oxidative degradation at room temperature. L-5-methyltetrahydrofolate calcium, the active form of folic acid, has high bioavailability but is easily oxidized and has poor stability. Table 2 shows that after 30 days of storage under high temperature, high humidity, and light conditions, the EPA-EE content and L-5-methyltetrahydrofolate calcium content of the fish oil soft capsules prepared according to this invention remained essentially unchanged, demonstrating the good stability of the fish oil soft capsules prepared according to this invention. Furthermore, long-term stability tests (Table 3) also confirm that the fish oil soft capsules prepared according to this invention have excellent stability and are suitable for long-term storage.
[0105] Example 9: Content Uniformity Test
[0106] The content uniformity test was conducted according to General Chapter 0941, "Method for Testing Content Uniformity," of the 2025 edition of the Chinese Pharmacopoeia. Ten fish oil soft capsules were randomly selected, and the content of L-5-methyltetrahydrofolate calcium was determined. The relative standard deviation (RSD) of the 10 single-dose content determination results was calculated. If the RSD was not greater than 5.0%, the content uniformity of the sample was considered to meet the requirements. The results are shown in Table 4.
[0107] Table 4 Results of content uniformity test
[0108] Example 10 Animal toxicity test
[0109] 1. Experimental objective: To observe the toxic effects of the fish oil capsules of this invention administered orally to SD rats for 28 consecutive days, and to determine the dose level at which no clinical adverse reactions were observed, so as to provide a reference for the safety of long-term clinical use.
[0110] 2. Experimental Materials and Methods
[0111] Test sample: The contents of fish oil soft capsules prepared in Example 4 of this invention.
[0112] Animals and grouping: Eighty SD rats, half male and half female, were randomly divided into four groups according to their body weight: solvent control group (sunflower seed oil), low-dose group (0.47 g / kg), medium-dose group (1.4 g / kg), and high-dose group (4.2 g / kg) of the test sample.
[0113] Dosing regimen: Rats in each group were administered the test sample or solvent at various concentrations orally via gavage once daily.
[0114] For four consecutive weeks, the gavage volume was 4 mL / kg.
[0115] Monitoring Indicators: All animals underwent daily clinical observation during the experiment. Body Weight: Weighed once before the experiment and once weekly during the experiment. Food Intake: Food intake was measured weekly after the start of the experiment. Ophthalmological Examination: All animals were examined once after grouping, and the solvent control group and high-dose group were examined once each on day 27 of the experiment. Urine: Measured once on day 27 of the experiment. On day 29 of the experiment, all animals were dissected, and blood was collected for hematological, coagulation, and blood biochemical tests. Gross necropsy, organ weighing, and histopathological examination were performed. Bone marrow cell differential counts were performed on the solvent control group and high-dose group animals at the end of the experiment.
[0116] 3. Test Results
[0117] Under the conditions of this experiment, SD rats were administered fish oil soft capsule contents orally for 4 consecutive weeks at doses of 0.47 g / kg, 1.4 g / kg, and 4.2 g / kg. No animals were near death or died during the experiment. No significant toxic reactions were observed in the animals based on clinical observation, body weight, food intake, ophthalmological examination, hematological indicators, blood coagulation indicators, blood biochemical indicators, urine indicators, bone marrow cell examination, gross necropsy, organ weight, and histopathological examination at each dose of fish oil soft capsule contents.
[0118] In summary, under the conditions of this experiment, SD rats were administered the contents of the fish oil soft capsules of this invention via oral gavage for 4 consecutive weeks, and the no-adverse-effect level (NOAEL) was 4.2 g / kg (equivalent to 116 times the recommended human dose). These results demonstrate that the fish oil product of this invention has good safety within the tested dosage range.
[0119] Example 11 Evaluation of the antidepressant effect of fish oil soft capsules using a zebrafish model
[0120] Test sample: The contents of fish oil soft capsules prepared in Example 4 of this invention.
[0121] Experimental animals and grouping: Wild-type AB strain zebrafish (5 days post-fertilization) were randomly divided into six groups: normal control group, model control group, positive drug control group (sertraline, 100 ng / mL), low-dose test sample group (31.2 μg / mL), medium-dose test sample group (62.5 μg / mL), and high-dose test sample group (125 μg / mL).
[0122] Model establishment: Zebrafish were placed in 6-well plates, with 30 fish per well and a volume of 3 mL per well. Except for the normal control group, all other groups were given reserpine (5 μg / mL, prepared as stock solution with DMSO) to establish a depression model.
[0123] Test sample preparation: The contents of the fish oil soft capsules were prepared into a 200 mg / mL stock solution in 100% DMSO, sonicated for 5 minutes, and then administered as a water solution at the corresponding final concentrations (31.2 μg / mL, 62.5 μg / mL, and 125 μg / mL). Sertraline, the positive control drug, was prepared into a 10 mg / mL stock solution in ultrapure water, sonicated for 5 minutes, and then administered as a water solution at a final concentration of 100 ng / mL. After treatment at 28℃ for 1 day, 10 zebrafish were randomly selected from each experimental group and transferred to a 24-well plate (1 zebrafish / well, 1000 μL / well). The proportion of time the zebrafish spent moving in the open field was measured using a behavioral analysis system to evaluate the antidepressant activity of the fish oil soft capsules.
[0124] Statistical analysis: Results are expressed as Mean ± SE. Statistical analysis was performed using SPSS software. A p-value < 0.05 was considered statistically significant compared to the model control group.
[0125] Table 5. Evaluation results of the antidepressant effect of fish oil soft capsules in a zebrafish model.
[0126]
[0127] As shown in Table 5, in the zebrafish animal model, the fish oil composition of the present invention dose-dependently increased the proportion of open field exercise time, and the medium and high dose groups showed significant differences compared with the model group, indicating that the fish oil of the present invention has antidepressant effects. Among them, the effect of the high dose group was close to that of the positive control drug sertraline.

[0138] Table 6 shows the results. The total HAMD17 score in both the experimental group (fish oil soft capsules of this invention) and the positive control group (fluoxetine hydrochloride capsules) decreased significantly from baseline, with statistically significant differences (P<0.05). After 8 weeks of treatment, the ΔHAMD17 score decreased by 9.29±4.31 points from baseline in the fish oil group and by 8.72±4.30 points in the positive control group. These results indicate that the fish oil composition of this invention has a clear efficacy in improving mild to moderate depression, and its effect is comparable to that of the classic antidepressant fluoxetine hydrochloride.
[0139] Of particular note is that the fish oil composition of the present invention, while achieving similar therapeutic effects to chemically synthesized drugs, also has the potential advantages of being naturally sourced and having high safety, which helps to improve patients' willingness to undergo treatment and their long-term adherence, and has a positive significance for improving the quality of life of patients with depression.
[0140] In summary, this invention provides a fish oil composition that combines proven antidepressant efficacy with high safety. Through scientific formulation of active ingredients and a specific preparation process, the core components, such as fish oil, are stably coexisted while achieving clinical efficacy comparable to conventional antidepressants. Furthermore, by utilizing dosage form design and flavor control, the palatability and patient compliance of the product are significantly improved. The fish oil composition provided by this invention offers a new and high-quality option for the management of mood disorders such as depression and anxiety.
