Abstract
A percutaneous paster of hydrophilic gel for medicine features that its gel layer contains the volatile oil of bupleurum root, hydrophilic gel, cross-linking agent, humectant, surfactant, filler, adhesive, osmosis promoter and solvent. Its preparing process is also disclosed.
Description
Technical field
The present invention relates to medical technical field, particularly relate to hydrophilic gel pleximetric paste that a kind of drug transdermal controlled release treatment uses and preparation method thereof.
Background technology
Hydrophilic gel pleximetric paste (crust cloth cream) is to be substrate with water-soluble high-molecular compound or hydroaropic substance, after medicine or Chinese medicine extract mix, coats the external paster of making on the non-woven fabrics.To biocompatibility, affinity, breathability, the sweat proof of skin with to repeat to take off pulling property all better, and be difficult for irritated.At the seventies initial stage, states such as Japan, Europe have begun to develop medical cataplasma, and along with the continuous development of medical industry, this novel form develops to some extent in China in recent years.According to World Health Organization's prediction, in the coming years, there is the medicine more than 30% will make percutaneous drug administration preparation into, will start the new upsurge of an inner disease outer treat.
But with the hydrophilic gel pleximetric paste complicated component of prior art development, and active constituent content is low, and portioned product has certain zest, easy sensitization, and come off easily.
Radix Bupleuri volatile oil is the volatile oil that has extracted the bupleurum Chinese of extensive use from clinically, main component is volatile oil in the injection of Radix Bupleuri that wherein uses clinically, it is clearing away heat and expelling pathogen in the exterior that the injection of Radix Bupleuri function cures mainly, the heating that is used for the treatment of flu, influenza, malaria etc. truly has curative effect (the accurate word Z41020926 of traditional Chinese medicines), Radix Bupleuri volatile oil is applied on the hydrophilic gel pleximetric paste was also meeting at present.
Summary of the invention
Problem to be solved by this invention is to propose a kind of hydrophilic gel pleximetric paste at above-mentioned prior art, its nonirritant, no anaphylaxis, no peeling phenomenon, sheet drug loading are far above the drug administration by injection amount, and the energy slow releasing pharmaceutical, make the medicine long action time, and reach the antipyretic purpose.
Another object of the present invention provides a kind of method for preparing hydrophilic gel pleximetric paste.
The present invention is adopted solution to be by the problem of the above-mentioned proposition of solution: hydrophilic gel pleximetric paste; include backing layer, gel layer and protecting film; its difference is that gel layer includes following component; Radix Bupleuri volatile oil, hydrophilic gel, cross-linking agent, wetting agent, surfactant, filler, adhesive, penetrating agent, solvent, described constituent content is by weight percentage
Radix Bupleuri volatile oil 1.0～20% hydrophilic gels 2.5%～10% cross-linking agent 0～1%
Wetting agent 20～40% surfactants 0～5% filler 0～0.1%
Adhesive 1～3% penetrating agent 1～12% solvent 40～74%;
Press such scheme, described hydrophilic gel is a sodium polyacrylate.
Press such scheme, described cross-linking agent is an organic acid, as any one or multiple mixing among tartaric acid, citric acid etc. and aluminium hydroxide, Glycine sodium, aluminum glycinate, the EDTA-4Na (tetrasodium ethylenediamine tetraacetate).
Press such scheme, described wetting agent is any one or the multiple mixing in glycerol, propylene glycol, sorbitol, the Polyethylene Glycol.
Press such scheme, described surfactant is a tween.
Press such scheme, described filler is any one in Kaolin, zinc oxide, micropowder silica gel, calcium carbonate, Bentonite, the titanium dioxide.
Press such scheme, described adhesive is any one among gelatin, CMC-Na (sodium carboxymethyl cellulose), the PVP-90 (polyvinyl pyrrolidone);
Press such scheme, described penetrating agent is two or more the mixing in ethanol, propylene glycol, glycerol, oleic acid, PEG300 (Polyethylene Glycol), PEG400, low mass molecule alcohol class, helium ketone, carbamide, Herba Menthae, Camphora, Borneolum Syntheticum, eucalyptus oil, the Fructus Cnidii oil.
Press such scheme, described solvent is a water.
The preparation method of hydrophilic gel pleximetric paste is with hydrophilic gel; adhesive; Radix Bupleuri volatile oil; surfactant; penetrating agent; filler is dispersed under stirring condition and forms the A phase in the wetting agent; cross-linking agent is dispersed in formation B phase in the solvent under stirring condition; again B is stirred under the certain vacuum condition and be scattered in A and form gel layer in mutually; then gel layer is coated on the non-woven fabrics; be covered with protecting film; cut to certain specification; produce the hydrophilic gel paster that contains Radix Bupleuri volatile oil through cold curing, described each constituent content is by weight percentage
Radix Bupleuri volatile oil 1.0～20% hydrophilic gels 2.5%～10% cross-linking agent 0～1%
Wetting agent 20～40% surfactants 0～5% filler 0～0.1%
Adhesive 1～3% penetrating agent 1～12% solvent 40～74%.
Can produce the main component of separating thermal effect among the present invention is Radix Bupleuri volatile oil, Radix Bupleuri volatile oil is the main component in the analgesic injection bupleurum Chinese injection of life-time service clinically, contain in the hydrophilic gel pleximetric paste of Radix Bupleuri volatile oil in the present invention, the consumption of Radix Bupleuri volatile oil is 1.0～20%.
In the present invention, the hydrophilic gel pleximetric paste employing hydrophilic gel that contains Radix Bupleuri volatile oil is a substrate, hydrophilic gel is a kind of substrate that has been widely used in the externally applied transdermal administration at present abroad, it is to nontoxic, non-stimulated, the no anaphylaxis of human body, be a kind of safe and reliable pharmaceutic adjuvant, the hydrophilic gel consumption is suitable with 4～10% among the present invention.
Radix Bupleuri volatile oil is volatile oils and fats material, the barrier action and the paster forming degree of skin is good when making the principal agent composition see through skin, so in percutaneous plaster of the present invention, based on hydrophilic gel substrate, solvent is water, add surfactant, wetting agent, cross-linking agent, adhesive, filler and penetrating agent, behind abundant mix homogeneously, coat mounting on the backing material of base non-woven fabrics, produce the hydrophilic gel pleximetric paste that contains Radix Bupleuri volatile oil.
The present invention is embodied in the following aspects in the effect aspect pharmacodynamic study and zest research and the anaphylaxis research:

2) safety research result
A) zest research: 1% Radix Bupleuri volatile oil hydrophilic gel pleximetric paste once and repeatedly external application does not see after 24 hours that any toxicity, side effect takes place.
B) anaphylaxis research: 1% Radix Bupleuri volatile oil hydrophilic gel pleximetric paste external application, anaphylactic reaction does not take place, the visible heatings such as hydrophilic gel pleximetric paste external curing flu, influenza and malaria that contain Radix Bupleuri volatile oil of the present invention be safety, reliably, have no side effect.
Beneficial effect of the present invention:
Hydrophilic gel pleximetric paste nonirritant of the present invention as can be seen from the above results, no anaphylaxis, nothing are peeled off reaction, the sheet drug loading is far above the drug administration by injection amount, and the energy slow releasing pharmaceutical, makes the medicine long action time, and reach the antipyretic purpose, and there is not any toxicity, side effect generation.
