Detailed Implementation
[0021] The following embodiments are used to further illustrate the present invention, but should not be construed as limiting the scope of protection of the present invention. Equivalent substitutions or corresponding improvements made by those skilled in the art without departing from the concept of the present invention should fall within the scope of protection of the present invention.
[0022] Example 1 Extraction Process The prescription for Five-Flavor Sweet Dew Bath is as follows: 700 g of Juniperus chinensis, 700 g of Rhododendron simsii, 700 g of Artemisia argyi, 700 g of Ephedra sinica, 700 g of Myrica rubra, 700 g of Celery scabra, 70 g of Polygonatum sibiricum, 70 g of Tribulus terrestris, 70 g of Asparagus cochinchinensis, 70 g of Nardostachys jatamansi, 35 g of Terminalia chebula, 35 g of Phyllanthus emblica, 35 g of Terminalia chebula, and 70 g of Mirabilis jalapa.
[0023] Preparation process: 1. Herbal Processing: Take Juniperus chinensis, Rhododendron simsii, Myrica rubra, Artemisia capillaris, Ephedra sinica, Celtis sinensis, Polygonatum sibiricum, Tribulus terrestris, Asparagus cochinchinensis, Nardostachys jatamansi, Terminalia chebula, Phyllanthus emblica, Terminalia chebula, and Mirabilis jalapa, and remove impurities. Spread the herbs to a thickness of no more than 5 cm and irradiate them under a UV lamp for 360–480 min, turning them over every 30 min. After irradiation, pulverize them and set aside.
[0024] 2. Extraction: Take the broken prescription herbs, add 12 times the amount of water, soak for 3 hours, and then heat and decoct for 2 hours. Filter the solution to obtain the filtrate. Add 10 times the amount of water to the dregs and heat and boil for 1 hour. Filter the solution to obtain the filtrate. Add 10 times the amount of water to the dregs for a third time and boil for 1 hour. Filter the solution and take the filtrate. Combine the filtrate obtained from the first two times to obtain the decoction.
[0025] 3. Concentration and Drying: The decoction is heated and concentrated to a relative density of 1.27–1.30 (50℃). The concentrated solution is then dried under reduced pressure at 75–80℃ and a vacuum of -0.07–-0.08 MPa. The resulting dry extract is pulverized and passed through a 100-mesh sieve to obtain extract powder.
[0026] Example 2: Five-Flavor Herbal Bath Effervescent Tablets Based on the material characteristics of the extract powder obtained in Example 1 and the preliminary screening results of excipients, citric acid, sodium bicarbonate, microcrystalline cellulose, pregelatinized starch, sodium carboxymethyl starch, croscarmellose sodium, and magnesium stearate were selected as excipients. The effects of the amount of extract powder, the mass ratio of citric acid to sodium bicarbonate, and the amount of other excipients on the effervescent tablet forming quality were investigated. The amounts of croscarmellose sodium and magnesium stearate were both fixed at 2%, and the mass ratio of microcrystalline cellulose, pregelatinized starch, and sodium carboxymethyl starch was initially set at 1:1:1. Disintegration time, dispersion state, gas production effect, and appearance were used as evaluation indicators, with each indicator having a full score of 25 points. The comprehensive scoring method is shown in Table 1.
[0027] Table 1. Comprehensive Evaluation Table for Effervescent Tablets
[0028] Orthogonal experimental design for molding process research To screen the formulation of Wuwei Ganlu medicinal bath extract effervescent tablets, the amount of extract powder (A), the mass ratio of citric acid to sodium bicarbonate (B), and the amounts of other excipients (C) were used as factors of consideration, with a blank factor (D) included. The L9(3) method was employed. 4 The experiment was conducted using an orthogonal array, with the comprehensive score as the evaluation index. The factor levels and orthogonal experimental arrangement are shown in Tables 2 and 3, and the experimental results and analysis are shown in Tables 4 and 5.
[0029] Table 2 Experimental Factor Levels
[0030] Table 3 Orthogonal Experimental Design
[0031] Table 4. Statistical Table of Orthogonal Experiments
[0032] Table 5. Analysis of Variance for Orthogonal Experiments
[0033] P<0.05; F0.05(2,2)=19.00, F0.01(2,2)=99.00.
[0034] Table 4 shows that the range R-values of each factor follow the order A > B > C > D, indicating that within the scope of the study, the order of influence of each factor on the overall score of Wuwei Ganlu medicinal bath extract effervescent tablets is: extract powder amount > acid-base ratio > other excipient amounts > blank factor. Among them, factor A has the largest range, indicating that the amount of extract powder has the most significant impact on the quality of effervescent tablet formation; factor B is next; and factor C has a relatively smaller impact.
[0035] Table 4 shows that the order of the range R values for each factor is A > B > C > D, indicating that within the scope of this experiment, the order of influence of each factor on the overall score is: amount of extract powder > mass ratio of citric acid to sodium bicarbonate > amount of other excipients > blank factor. A visual analysis based on the k values of each factor reveals that the optimal combination is A2B2C3. Given that the total amount of each component in the formulation should be 100% by mass percentage, and that there is a proportional relationship between the amount of extract powder and other excipients, the final formulation combination still needs to be confirmed based on the actual supplementation methods of each experimental formulation and the original experimental records. Based on the formulations used in the existing validation experiments, the example uses the A2B2C2 combination as the validation formulation.
[0036] Analysis of variance was performed on the data listed in Table 5. The F-value for factor A was 29.0400, which is greater than F0.05(2,2) = 19.00 but less than F0.01(2,2) = 99.00, indicating that factor A is statistically significant at the α = 0.05 level. The F-values for factors B and C were 4.3625 and 1.9837, respectively, neither of which reached the α = 0.05 level. Given the low degrees of freedom of error in this experiment and the possibility that the total prescription constraint may affect the independence of factors, the statistical results are only for prescription screening reference, and the final process will be based on the results of the validation experiment.
[0037] Based on existing validation tests, the effervescent tablet formulation and manufacturing process are as follows: 20 g of extract powder, 25 g of citric acid, 30 g of sodium bicarbonate, 7 g of microcrystalline cellulose, 7 g of pregelatinized starch, 7 g of sodium carboxymethyl starch, 2 g of cross-linked sodium carboxymethyl cellulose, and 2 g of magnesium stearate; after mixing all materials evenly, dry granulation and tableting are performed to obtain the final product.
[0038] Process verification test Based on the results of orthogonal experiments, and combined with the formulation coordination, formulation formability and production practice, the optimal formulation process for Wuwei Ganlu medicinal bath extract effervescent tablets was determined as follows: Take 20 g of extract powder, add 25 g of citric acid, 30 g of sodium bicarbonate, 7 g of microcrystalline cellulose, 7 g of pregelatinized starch, 7 g of sodium carboxymethyl starch, 2 g of cross-linked sodium carboxymethyl cellulose and 2 g of magnesium stearate, mix evenly, and then granulate and compress the mixture using a dry method to obtain the final product.
[0039] Three batches of validation tests were conducted according to the above-mentioned optimized molding formulation process, and the particle yield and repeatability were calculated. The results are shown in Table 6. The particle yields of the three batches of samples were 99.6%, 99.7%, and 99.5%, respectively, with an average of 99.6% and an RSD of 0.1%, indicating that the process is stable and has good repeatability.
[0040] Table 6 Results of Molding Process Verification Tests
[0041] Table 6 shows that the particle yield of the three batches of samples was 99.5%–99.7%, with an average of 99.6% and an RSD of 0.1%, indicating that the process had good repeatability in the tested batches.
[0042] Meanwhile, the effervescent tablets prepared according to the above-mentioned prescription process were examined for effervescent disintegration time, dispersion state, gas production effect and appearance.
[0043] The Five-Flavor Dew Bath Extract Effervescent Tablets prepared by this invention can rapidly generate continuous and uniform bubbles in water at 40℃~45℃, with effervescence completion time less than 2 minutes. After effervescence, the tablets basically disintegrate, and the liquid is brownish-yellow to brownish-brown, with relatively uniform dispersion. No obvious hard core, large floating particles, or agglomeration are observed, indicating that the preparation has good effervescent disintegration performance and immediate dispersibility.
[0044] Specific results: The disintegration times of the three batches of samples were 1.58 min, 1.71 min, and 1.64 min, respectively, with an average disintegration time of 1.64 min, all of which were completed within 2 minutes. When the samples were added to warm water, the tablets disintegrated and dispersed rapidly, producing uniform and continuous gas with abundant bubbles, lasting approximately 1.5–2.0 min. The resulting solution was yellowish-brown, relatively homogeneous, and showed no obvious clumping after standing. A small amount of fine suspended matter was visible, but no large particles were visible to the naked eye. The resulting effervescent tablets were intact, relatively uniform in thickness, with a smooth surface and neat edges, without cracks, loose tablets, obvious missing edges or corners, or significant powdering. This indicates that the effervescent tablets produced by this formulation process have good formability and performance characteristics.
[0045] Summary of the research on the process of Five-Flavor Sweet Dew Medicated Bath Extract Effervescent Tablets: The first soaking was done with 12 times the amount of water for 3 hours, followed by decocting for 2 hours. The second and third soakings were done with 10 times the amount of water for 1 hour each. The decoctions were combined, filtered, and concentrated until the relative density at 50°C was 1.27–1.30. The decoction was then dried under reduced pressure at a vacuum of -0.07–0.08 MPa and a temperature of 75–80°C. The powder was then pulverized and passed through a 100-mesh sieve to obtain the Five Flavors Sweet Dew Bath Extract Powder. Citric acid, sodium bicarbonate, microcrystalline cellulose, pregelatinized starch, sodium carboxymethyl starch, croscarmellose sodium, and magnesium stearate were added to the extract powder. After mixing evenly, the mixture was granulated by dry method and compressed into tablets to obtain the Five Flavors Sweet Dew Bath Extract Effervescent Tablets.
[0046] The preferred formulation for effervescent tablets is as follows: 20% extract powder, 55% total effervescent agent, with a citric acid to sodium bicarbonate mass ratio of 1:1.2, 21% other excipients, 2% croscarmellose sodium, and 2% magnesium stearate; the mass ratio of microcrystalline cellulose, pregelatinized starch, and sodium carboxymethyl starch in the excipients is 1:1:1. Effervescent tablets prepared using this formulation have an average disintegration time of 1.64 min, uniform and continuous gas production, a yellow-brown solution, relatively uniform dispersion, and no obvious large particle residue; the tablets are intact, with a relatively smooth surface and good formability. This indicates that the effervescent tablets obtained by this process have controllable quality, stable process, and are convenient to use, store, and carry.
[0047] Example 3: Five-Flavor Sweet Dew Effervescent Tablets Based on the results of the process research, combined with the yield, excipient dosage, and dosage form (0.5 g / tablet), the formulation and preparation process are as follows: prescription: Juniperus chinensis 664.17g, Rhododendron simsii 664.17g, Artemisia capillaris 664.17g Ephedra 664.17g, Bryus officinalis 664.17g, Celery shavings 664.17g Polygonatum 66.42g, Tribulus terrestris 66.42g, Asparagus cochinchinensis 66.42g Nardostachys chinensis 66.42g, Terminalia chebula 33.21g, Phyllanthus emblica 33.21g Terminalia chebula 33.21g, Mirabilis jalapa 66.42g (or these ingredients in parts by weight).
[0048] Preparation process: The prescription medicinal materials are decocted three times with water. For the first decoction, 12 times the amount of water is added, the herbs are soaked for 3 hours, and then decocted for 2 hours. For the second and third decoctions, 10 times the amount of water is added, and each decoction is decocted for 1 hour. The decoctions are combined, filtered, and the filtrate is concentrated to a relative density of 1.27–1.30 (50℃). The filtrate is then dried under reduced pressure (vacuum degree -0.07–-0.08 MPa, 75–80℃), pulverized, and passed through a 100-mesh sieve. 125g of citric acid, 150g of sodium bicarbonate, 35g of microcrystalline cellulose, 35g of pregelatinized starch, 35g of sodium carboxymethyl starch, 10g of croscarmellose sodium, and 10g of magnesium stearate are added. The mixture is then granulated by dry method and compressed into 1000 tablets.
