Description

Preparation of shaolin plaster for rheumatism and wound

The invention belongs to field of pharmaceutical technology, a kind of specifically Chinese medicine class medicine for external use is the succedaneum of shaolin plaster for rheumatism and wound rubber emplastrum, is the up-to-date dosage form of external plaster.

External-use drug form is mainly based on rubber emplastrum at present.The preparation method of rubber emplastrum generally is:

Rubber is cleaned, 50-60 ℃ of heat drying or dry, be cut into bulk, mastication reticulates thin slice in rubber mixing machine, eliminates static 18-24 hour, be dipped in an amount of gasoline, treat to stir in the rearmounted adhesive supplier of swelling, the back gradation that stirs adds vaseline, lanoline, zinc oxide and Colophonium, add medicine again and stir evenly, be coated with cream.

There are many deficiencies aborning in rubber emplastrum:

1, the high temperature in the production process makes the effective ingredient loss in the mastic bigger, need 100 ℃ of temperature about agent in process of production, so that coating is produced, the Borneolum Syntheticum in the mastic, Mentholum, methyl salicylate and volatile ingredient are lost in about 30-40% behind high temperature after testing.

2, human body skin is easily produced stimulation, cause red swelling of the skin and scratchy, because rubber emplastrum adds viscosifier such as Colophonium in process of production, hold still residual about 6 ‰ the gasoline of rubber emplastrum that the agent method is produced, rosin acid and gasoline can cause stimulation to human body skin, cause allergy, because rubber emplastrum viscosity is stronger, easily cause physical property to pull simultaneously human body skin.

The present invention seeks to disclose a kind of preparation of shaolin plaster for rheumatism and wound.Adopt temperature production, water-soluble high-molecular substance is a substrate, thereby has preserved the biological activity of active substance, and skin is not had any stimulation, owing to added transdermal agent, medicine releasability and transdermal characteristic is strengthened greatly.

The substrate of shaolin plaster for rheumatism and wound of the present invention is the hydrophilic plaster that a kind of polyethylene oxide and polyacrylic acid slaine are formed, polyethylene oxide and polypropylene have constituted its skeleton, form by certain multistage alcohol in the side, have stable characteristics such as long preservation and combating microorganisms decomposition, chafe not, can prevent the skin alligatoring, because the steam of multistage alcohol forces down, can make lubricant, the flexibility and the stability that have kept plaster, polyacrylic acid slaine and genuine milk fiber derivative have the effect that prevents effective ingredient and moisture evaporation, can improve simultaneously the thermostability of cataplasma, the effect of mouldability and oil preparation dispersibility, hydrophilic polymeies such as polyacrylic acid polymeric metal salt and carboxymethyl cellulose, make the good adhesive performance of its tool, conformality, water-retaining property and guarantor's oiliness, also have and the good characteristics of various ingredient intermiscibilities, can make the effective ingredient of medicine enter subcutaneous tissue slowly, brought into play long lasting effect.

This product is erythroid lamellar water soluble plaster, gas fragrance.The every 100cm paste containing amount of paste containing amount is more than the 4g.

Check:

Get 5 of this product, add the moistening 20ml of the adding diethyl ether supersound process of 60ml ammonia solution 30 minutes, inclining ether extracted liquid, and evaporate to dryness, residue add dehydrated alcohol makes dissolving in right amount, and standardize solution is in the 5ml volumetric flask, as need testing solution.Other gets the aconitine reference substance, adds dehydrated alcohol and makes the solution that every 1ml contains 1mg, in contrast product solution.According to the thin layer chromatography test, draw need testing solution 1ul, reference substance solution 5ul puts respectively on same silica gel g thin-layer plate, is developing solvent with benzene one ethyl acetate, one diethylamine (7: 2: 0.5), launches, and takes out, and dries, and spray is with rare bismuth potassium iodide test solution.In the test sample chromatograph, with reference substance chromatograph relevant position on the speckle that occurs should be less than the speckle of reference substance.

Get 10 of this product, put in the 250ml boiling flask, add water 150ml, connect the volatilization determinator.Add water makes and is full of the scale part from determinator upper end, and overflow is gone into till the flask, add ethyl acetate 5ml again, connect reflux condensing tube, reflux 40 minutes moves to separatory funnel with the liquid in the volatile oil determination apparatus, divides and gets the ethyl acetate layer, filter with the funnel that is covered with anhydrous sodium sulfate, filtrate is product solution in contrast.Other gets Mentholum 8mg and Borneolum Syntheticum 8mg and methyl salicylate 8mg, adds ethanol 10ml solution.According to the gas chromatography test, column length is 2m, is fixative with Polyethylene Glycol (PEG)-20M, and coating concentration is 10%, and column temperature is 130 ℃.Get reference substance solution respectively and need testing solution is an amount of, inject gas chromatograph.Test sample presents the chromatographic peak identical with the reference substance retention time.
