Abstract
The present invention relates to a traditional Chinese medicine gel plaster for treating facial paralysis and its preparation method, composed of 5%-50% of extract of traditional Chinese medicine and 95%-5% of medicinal adjuvant. The traditional Chinese medicine plaster is prepared by mixing the molecule gel, the hydrogel, active ingredients of medicine extracts with the plural gel factor. Different medicine extracts enter into the skin through different channels. The oil-soluble component in molecule gel has repulsion force to the water-soluble medicine and the water-soluble component in hydrogel has repulsion force to the oil-soluble medicine therefore the medicine absorption is promoted and the medicine efficacy is increased.
Description
Technical field
The present invention relates to the up-to-date molecular gel of Percutaneously administrable preparation technical field combines with hydrogel and makes profit ampholytic gels patch, adopt mixing active ingredients thing that Radix Achyranthis Bidentatae, Fructus Chaenomelis, Caulis Spatholobi, Mel four flavor Chinese medicine compositions extract for the basis in addition the medicinal substrate preparation have treatment facial paralysis Transdermal absorption gel adhesive and preparation method thereof, specifically be a kind of Chinese medicine profit ampholytic gels patch for the treatment of facial paralysis.
Background technology
Transdermal drug delivery system or percutaneous absorption patch refer to stick the mode medication through skin, and medicine enters the systemic blood circulation by skin absorbs and reaches a class preparation of effective blood drug concentration, realization disease treatment or prevention.The characteristics of percutaneous absorption patch are, transdermal drug delivery system can avoid the first pass effect of liver and medicine in the gastrointestinal deactivation, the absorption of medicine is not subjected to the influence of gastrointestinal factors, reduce the individual variation of medication, keep constant effective blood drug concentration or physiological effect, the blood drug level peak valley phenomenon of avoiding oral administration to cause reduces toxicity.Reduce administration number of times, improve therapeutic efficacy, prolong action time, avoid multiple dose administration, make most patient be easy to accept, simultaneously easy to use, independently medication of patient also can be cancelled medication at any time.
So-called profit ampholytic gels is not the zwitterion that we say usually, because molecular gel generally all is as solvent by oil-based solvent, organic solvent or the mixture of the two, it is gel with oleophilic properties, and used aqueous solvent accounts for greatly in the hydrogel, it is the gel of possess hydrophilic property matter, the two is used, so be called the profit ampholytic gels.
Molecular gel is that the gel factor (some micromolecule organic compound) is passed through non-covalent interaction in non-aqueous media, spontaneously assembles, assembles orderly three-dimensional fiber network structure, makes the medium gelation.Molecular gel has reversible characteristics of heat, and processing technology is simple, and gelinite contains a large amount of organic solvents, be fit to the storage storehouse as lipophilic medicament, but molecular gel exists cohesiveness low, and viscosity is little, with the skin poor compliance, is not suitable for making shortcomings such as patch.Hydrogel water content height is fit to the storage storehouse as hydrophilic medicament, and is strong to the skin compliance, but is subjected to the influence of self property, and colloid poor plasticity, elasticity are little.In sum, be advantage in conjunction with these two kinds of gels, adopt the pluralgel factor that two kinds of gelinites are disperseed mixing, with the molecular gel is framework material, the patch substrate that hydrogel is made as sticky stuff, both high resilience forms have good compliance with skin, can peel off repeatedly, paste again, improve the drug loading of hydrophilic medicament and hydrophobic drug simultaneously again.Two kinds of gels twine staggered uniform distribution in substrate, by non-covalent bond form combinations such as Van der Waals forces, by fully contacting with skin, the both sexes medicine continues to see through skin through passage separately, enters blood circulation, the performance drug effect.
Facial paralysis (facial neuritis, bell's palsy, hunter syndrome), be commonly called as " facial paralysis ", " wapperijaw crust " " wapperijaw ", " facial paralysis ", " hang skew wind ", " facial neuritis ", " wapperijaw wind " etc., be to be a kind of commonly encountered diseases of principal character with facial expression muscle group dyskinesia, its cardinal symptom is facial expression muscle functional defect or forfeiture, cause distortion of commissure, hypophasis, facial expression is stiff, language inconvenience, food is detained in the Ipsilateral bicker, even Ipsilateral corneal clouding, blind, cause ugly face, give patient's life, the worker does with social activity and brings very big difficulty, make the patient lose the confidence and the courage of participating in society, in addition overwhelmed with sorrow.It is a kind of commonly encountered diseases, frequently-occurring disease, and it is not subjected to age limit.Facial paralysis is divided on every side two kinds of property and central.Wherein the peripheral facial paralysis sickness rate is very high, and the most common person is facial neuritis or Bell's palsy.The normal facial paralysis of saying of usual people institute is meant facial neuritis as a rule.
The treatment of facial paralysis, central paralysis should be at the cause of disease, and paralysis peripherica should take appropriate measures according to the morning and evening of the course of disease.The early treatment of paralysis peripherica, purpose is to manage to recover the function of nerve, and method comprises: acupuncture, decompression, nerve anastomosis, neural transplantation or nerve cross anastomosis and neural Coronary Artery Bypass etc.The anaphase of paralysis peripherica, purpose are to manage to correct deformity and improve function, be used for after early stage treatment, often between with examining observation, recover dissatisfied, or confirm the case of recovering hopeless.The later stage plastic operation has static(al) support and power to support two kinds of methods, the degree of deformity severe patient, and still needing cooperates complementary operation, to heighten the effect of a treatment.
Treatment for facial paralysis, on Western medicine, do not have reasonable medicine now, great majority are just started with from uncomfortable symptom such as the pain of reduction of patient, can not treat its basic effective medicine, and clinical treatment means treatments such as acupuncture, massage are adopted in treatment by Chinese herbs mostly.The treatment of facial paralysis is long the course of treatment, and medical expense is relatively more expensive, is difficult for being accepted by masses, and now, the treatment facial paralysis is the reasonable treatment preparation of neither one also.
