preparation example Construction

[0013] The preparation method of the hydrophilic traditional Chinese medicine patch comprises the following steps: (1) adding water to swell carbomer, adding triethanolamine to adjust the pH to 7.0-10.0; adding 3-5 times the weight of carbomer to medicinal gelatin or edible gelatin Dissolve in water at 35-60°C to obtain gelatin solution; add 5-10 times the weight of water to dissolve tragacanth gum to obtain tragacanth gum solution; ; adding gelatin solution, tragacanth gum solution and polysaccharide solution to the swollen carbomer, mixing evenly to obtain matrix I;

[0014] (2) Mix glycerin and propylene glycol evenly, add carboxymethylcellulose sodium, medicinal sodium polyacrylate, citric acid, eucalyptus oil, frankincense and myrrh crushed to the finest powder, kaolin or diatomaceous earth in sequence, and mix well Substrate II is obtained later;

[0015] (3) Mix base I and base II uniformly at 35-60°C, and add the alcohol-soluble extract of traditional Chinese medicine...

Abstract

The invention relates to hydrophilic Chinese medicinal patch and a preparation method thereof, and can effectively solve the problems that the package size of the effective medicines of the conventional patch is small, and the conventional patch is airtight. According to the technical scheme, a gelatin solution, a tragacanth solution and a Chinese herbal compound extraction polysaccharide solution are added into swelled Carbomer and mixed uniformly to prepare a substrate I; glycerin is mixed with propylene glycol uniformly, and sodium carboxy methyl cellulose, medicinal sodium polyacrylate, citric acid, eucalyptus oil, frankincense, myrrh, kaolin and diatomaceous earth are sequentially added into the mixture of the glycerin and propylene glycol and mixed uniformly to prepare a substrate II; the substrate I is mixed with the substrate II uniformly, a Chinese herbal compound alcohol soluble extract, borneol and menthol are added into the mixed substrate of the substrate I and the substrate II, fully and uniformly mixed, coated, cut and packaged to prepare the hydrophilic Chinese medicinal patch. The Chinese medicinal patch is reasonable in compatibility, has an exact reliable in curative effect and big viscosity, and is difficult to fall off, and favorable for transdermal absorption of skin; a manufacturing process is simple, practicable and economic; and the social benefit is obvious.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a hydrophilic traditional Chinese medicine patch and a preparation method thereof. Background technique [0002] Plaster is an important part of traditional medicine in my country. It has a history of more than 2,000 years. It has advantages that other dosage forms cannot match. It is convenient to use, can be administered continuously, and can be interrupted at any time. After effect, the blood concentration is stable. The plasters currently on the market mainly use traditional rubber plasters or hot-melt pressure-sensitive adhesives as matrix materials. These matrix materials are large and thin in appearance. Stimulating allergies and unable to alleviate the efficacy of the drug, generally only fat-soluble drugs can be loaded, which greatly limits the development of plasters. Traditional gel patches have high matrix content, low water retention, and low matrix viscosity. Contents of ...
