Problems solved by technology

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 weight gain is more than 70%), and it is prone to mottling, discoloration, lobes, etc., and it cannot be packaged. Enteric-coated tablets

Abstract

The invention discloses a preparation method of a bezoar detoxifying film coated tablet. The method comprises the following steps: 1) raw material treatment, namely, taking the following raw materials in parts by weight: 5 parts of calculus bovis factitious, 50 parts of realgar, 200 parts of gypsum, 200 parts of rhubarb, 50 parts of scutellaria baicalensis, 100 parts of platycodon grandiflorum, 25 parts of borneol and 50 parts of liquorice, crushing realgar into superfine powder, crushing rhubarb into fine powder, grinding the calculus bovis factitious and borneol, decocting water and decocting the other materials twice and two hours each time, merging decoction, filtering and concentrating the filtrate into thick paste; (2) tabletting, namely, adding rhubarb and realgar powder, and 8 parts of auxiliary starch to be prepared into particles, drying, adding the calculus bovis factitious powder and the borneol powder, mixing evenly and tabletting to prepare the tablet; and (3) coating, namely, putting the tablet into a coating pan, directly spraying a coating solution by trundle pan coating, wherein the amount of the coating solution is 0.02-0.05 part by weight, the coating solution comprises the following components in percentage by weight: 10%-15% of carboxyethyl cellulose, 10%-15% of a momordica grosvenori extract, 1%-3% of microcrystalline cellulose, 0.1%-0.5% of guar gum and the 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 Niuhuangjiedu 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 weight gain is more tha...
