Embodiment 1
[0016] 1. Take 32g of hydroxypropylmethylcellulose, 6g of triethyl citrate, 8g of xylitol, 7ml of castor oil, 805ml of Tween, 14g of dextrin, 6g of micronized silica gel, 10g of corn protein, and 1% food coloring solution Add 8ml, 360ml of distilled water at 42±1°C, and 95% ethanol to 1000ml.
[0017] 2. Production process (dosage as 1):
[0018] ①Use distilled water at 42±1°C to dissolve hydroxypropylmethylcellulose and triethyl citrate with ethanol for later use, and add castor oil and Tween-80 to the ethanol solution of triethyl citrate for later use;
[0019] ②After mixing the liquid described in step 1 evenly, add dextrin, micronized silica gel and corn gluten through an 80-mesh sieve in turn, then add food coloring solution, stir evenly, pass through the colloid mill for 5 times and set aside;
[0020] ③Sieve out the fine powder, fragments and debris in the tablet, put the tablet in the coating pan and preheat it to 48±2°C, spray the coating material on the tablet, and ...
Embodiment 2
[0024] 1. The film coating formula is: 38g of hypromellose, 7g of triethyl citrate, 6g of xylitol, 5ml of castor oil, 807ml of Tween, 17g of dextrin, 8g of micronized silica gel, 7g of corn protein, Add 6ml of 1% food coloring solution, 400ml of distilled water (47±1°C), and 95% ethanol to 1000ml.
[0025] 2. The coating process is the same as in Example 1.
Embodiment 3
[0027] 1. The film coating formula is: 38g of hypromellose, 7g of triethyl citrate, 6g of xylitol, 5ml of castor oil, 807ml of Tween, 17g of dextrin, 8g of micronized silica gel, 7g of corn protein, Add 6ml of 1% food coloring solution, 400ml of distilled water (47±1°C), and 95% ethanol to 1000ml.
[0028] 2. The coating process is the same as in Example 1.
[0029] The Ganmaoqing tablet made by the process of the present invention and the Ganmaoqing tablet made by the sugar-coating process are sampled and tested, and the appearance results are as follows:
[0030] Sugar-coated tablets: uneven surface, uniform color, bright and bright.
[0031] Film-coated tablets: complete shape, firm coating, consistent thickness, uniform color, good finish, but the color is slightly duller than sugar-coated tablets. Sugar-coated tablets will fade, burst, dissolve, and disintegrate for more than 60 minutes under direct infrared radiation at 70-80°C and -5°C.
