Preparation method of compound recipe andrographitis thin membrane coated tablet

Abstract

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.

Description

technical field

[0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a preparation method of compound Andrographis paniculata film-coated tablets. Background technique

[0002] Pharmaceutical coating is to spray a thin film with good stability on the tablet embryos pressed from raw materials to cover up the taste of the drug tablet itself and increase the stability of the tablet, avoiding chemically active drugs and other substances Deterioration due to chemical reaction, etc. The traditional coating technology is sugar coating, and the excipients used are mainly talcum powder, syrup, etc. The sugar-coated tablets using talc powder can increase the weight of the drug tablet core by 50-100%, causing patients to take a large amount irrelevant to the drug ingredients accessories. Traditional sugar coating has the following disadvantages: high labor intensity, cumbersome process, thick coating layer, many materials (tablet weig...
