The invention discloses a preparation method of a compound
recipe andrographitis
thin membrane coated tablet. The preparation method of the compound
recipe andrographitis
thin membrane coated tablet comprises the following steps: 1)
processing raw materials, namely weighing 600 parts by weight of andrographitis and 1400 parts by weight of clorodendron eyrtophyllum,
grinding the andrographitis and clorodendron eyrtophyllum into
fine powder, weighing 540 parts by weight of andrographitis
fine powder and 1400 parts by weight of clorodendron eyrtophyllum
fine powder, mixing, adding water with the weight 3 times that of the mixture, carrying out ultrasonic extraction for 30 minutes, centrifuging, adding water with the weight 2 times that of
herb residue, carrying out ultrasonic extraction for 30 minutes, centrifuging, mixing decoctions, standing, filtering, and concentrating filtrate to obtain thick paste; 2) tabletting, namely adding the rest of andrographitis fine
powder, uniformly mixing, adding auxiliary materials, granulating, and pressing to obtain compressed tablets; 3)
coating, namely putting the compressed tablets into a
coating pan, and spraying all the
coating fluid by adopting a rolling coating method, wherein dosage of the coating fluid is 0.02-0.05 part by weight, and the coating fluid is composed of the following components in percentage by weight: 10-15% of
sodium hydroxyethyl cellulose, 10-15% of
momordica grosvenori swingle extract, 1-3% of
microcrystalline cellulose, 0.1-0.5% of
guar gum and balance of
purified water.
