Description
Technical field
The invention belongs to technical field of Chinese medicines, be specifically related to a kind of oral cavity disintegration tablet and preparation method thereof with warming the meridian and activating blood circulation, regulating QI to relieve pain effect.Oral cavity disintegration tablet of the present invention is referred to as pained peaceful oral cavity disintegration tablet again.
Technical background
Oral cavity disintegration tablet is a kind of new pharmaceutical preparation, and it can absorb through hypoglossis mucous membrane, directly enters blood, has avoided first pass effect effectively, so taking dose is little, and safety is good, and effect rapidly.Though be oral formulations, can reach the effect of ejection preparation.Therefore just progressively become the focus that pharmaceutical manufacturer and research and development field are paid close attention to.This dosage form mainly is to select suitable fast disintegrant, by the existing certain rigidity of its tablet of making, certain sedimentation is arranged again.Can not need the water assisting deglutition when taking, can rapid disintegrate become fine grained in the oral cavity, only several swallowing acts can be finished drug administration process.Its more common solid orally ingestible absorbs fast, bioavailability height, and taking convenience.
The preparation oral cavity disintegration tablet will be considered the problem of following critical aspects: 1, the advantage of oral cavity disintegration tablet just is rapid disintegrate, and it is fast to discharge medicine, reaches rapid-action effect, seeks suitable disintegrants, to guarantee oral cavity disintegration tablet disintegrate rapidly in the oral cavity; 2, seek relatively inexpensive pharmaceutic adjuvant, to reduce production cost; 3, only need the just disintegrate fully of water of minute quantity owing to disintegrating tablet, therefore must consider stability, prolongation shelf life and the shelf-life of humidity environment oral cavity disintegration tablet higher relatively in the process of storage, significant to medical manufacturing enterprise.
Disintegrating agent is commonly used in the oral cavity disintegration tablet adjuvant have low-substituted hydroxypropyl cellulose (L-HPC), cross-linking sodium carboxymethyl cellulose (CCNa), crospolyvinylpyrrolidone (PVPP), crosslinked carboxymethylstach sodium (CCMS-Na) etc. [He Jianchang, etc.New oral solid quick releasing formulation-oral cavity quick disintegrating slice.The pharmacy practice magazine, 2000,18 (3): 151].These adjuvants are all water insoluble, but a common characteristic is all arranged, and have hygroscopicity [pharmaceutical preparation portion of Shanghai Institute of Pharmaceutical Industry, Pharmaceutical National Engineering Research Center exactly.Pharmaceutic adjuvant application technology (second edition), Chinese Medicine science and technology publishing house, 2002,73～75].In the higher environment of humidity, oral cavity disintegration tablet is the moisture absorption especially easily, and cracked trend is arranged.So relatively harsher to environment requirement in production, storage and transportation with the oral cavity disintegration tablet that these adjuvants are made, must adopt special packing, seal cover, desiccant bag etc., all can produce considerable influence to production cost.And above-mentioned disintegrating agent all is synthetic through chemical process, and price is higher, for the more relatively oral cavity disintegration tablet of adjuvant content, can cause production cost to increase, and and then can increase patient's financial burden.Therefore, seek disintegrating agent functional, that price is suitable, make that the disintegration time of oral cavity disintegration tablet is shorter, price is more cheap, stability better becomes one of key problem in technology of exploitation oral cavity disintegration tablet.
Application number is 99802175 patent application bibliographical information, and during as disintegrating agent, the hardness of making oral cavity disintegration tablet is identical with disintegration time at the erythritol that uses separately equivalent or low-substituted hydroxypropyl cellulose (L-HPC).The erythritol sweet taste is pure, after eating nice and cool mouthfeel characteristic is arranged, and also can make correctives and use, and reduces the weight of oral cavity disintegration tablet.Erythritol can not influence normal carbohydrate metabolism, is fit to diabetes patient; And be sweet taste material low in calories, be suitable for obese patients, simultaneously caries prevention is also had positive role.
Chitin is the relatively low natural pharmaceutic adjuvant of a kind of price, and it has another name called chitin, chitin, is a kind of biological polysaccharide polymer material, extensively is present in the carapace in the unicellular lower eukaryote.This material can be degraded by lyase, has excellent biological compatibility, avirulence, chemical property quite stable.
Pained rather is to be that raw material is made compound preparation with Cortex Cinnamomi, Rhizoma Chuanxiong, Rhizoma Cyperi (processed with vinegar) medical material, existing drop pill and spray.Main effective ingredient in the Cortex Cinnamomi is a volatile oil, but it is volatile, meets light and heat instability [Inst. of Exploiting of Medical Plant Resource, Chinese Academy of Medical Scienc.Chinese medicinal herbal (the 5th).The People's Health Publisher, 1994,388; " one one of Chinese pharmacopoeia version in 2000,105].Volatile oil in the Rhizoma Chuanxiong also have very strong pharmacologically active Rhizoma Cyperi have promoting the circulation of QI to relieve pain effect [Xu Caihua, etc.Promoting the circulation of QI to relieve pain words Rhizoma Cyperi.The Zhejiang traditional Chinese medical science, 2002,6:258], volatile oil be its active site [yellow perilous peak, etc.Chemical constituent of Rhizoma Cyperi and pharmacological research progress].Two kinds of dosage forms all adopt following preparation technology to extract effective ingredient in the medical material: Cortex Cinnamomi, Rhizoma Chuanxiong medical material extract volatile oil with steam distillation; Medicinal residues adopt decoction and alcohol sedimentation technique to obtain all the other effective ingredient again; Rhizoma Cyperi (processed with vinegar) adopts 80% ethanol percolation to obtain effective ingredient.
Traditional steam distillation extracts volatile oil, and some material is big owing to its molecular weight, boiling point is high, volatility is little is difficult to proposition; Add extraction time long, temperature is high, and some compound decomposition is destroyed, and can't propose original actualization compound.Decoction and alcohol sedimentation technique is in sedimentary process, and impurity can adsorb and wrap up some effective ingredient.
Application number is 01102671 patent application document, adopts the preparation technology of microwave extracting, concentrating under reduced pressure, supersonic jet technology to obtain nano medicine ' Xintongning ', the method duration, and step is many, and is many to the loss of volatile ingredient.Fundamentally do not solve the defective of above-mentioned preparation method.
Supercritical extraction extraction time weak point, total yield height and extracts active ingredients are complete, and low-temperature extraction makes effective ingredient be difficult for decomposing destruction simultaneously, volatile component contained in the medical material effectively can be extracted.
