Description

Pharmaceutical composition of a kind of protect against osteoporosis and preparation method thereof
Technical field
The present invention relates to pharmaceutical composition of a kind of protect against osteoporosis and preparation method thereof.
Background technology
Osteoporosis (osteoporosis, OP) reduces with bone amount and the degeneration of osseous tissue fibre structure, then causes skeletal fragility and fracture risk to increase to the systemic skeletal disease of feature, leapt to the 7th into world's commonly encountered diseases sickness rate at present.Along with China's life-time dilatation per capita, social senilization, the sickness rate of OP also significantly increases, and has become the important public health problem affecting Chinese society.According to China drug in some provinces statistics, the sickness rate of the old people OP of more than 60 years old is about 59.89%.The sickness rate of the annual concurrent fracture because of OP is about 9.6%, and has the trend increased year by year, brings serious burden to society, family.Therefore, to screen and to develop anti-OP medicine significant.
At present, Western medicine adopts the medicine such as calcium preparation and vitamin D, bis phosphoric acid salt, calcitonin, selective estrogen receptor modulators for the treatment of OP more, although achieve certain curative effect, needs conbined usage more, simple medication is for this complex lesions of OP, and difficulty plays long-term effect; The drawbacks such as the carcinogenecity that medical expense is high in addition, the course for the treatment of is long, untoward reaction is many and potential, its clinical practice is restricted, therefore current treatment status are unsatisfactory.
In view of modern medicine does not have the medicine of good control OP, many doctors turn to TCM Therapy sight.Compared with western medicine, Chinese medicine is prevented and treated in process integrally-regulated emphatically at OP, determination for the treatment of based on pathogenesis obtained through differentiation of symptoms and signs, transfer endogenous cause of ill, act on multiple link, finally reach the effect of correcting body hormone imbalances and negative calcium balance, and there is the unique advantage that toxic and side effects is little, late result is good, in control OP, achieve larger progress.OP belongs to Chinese medicine " atrophic debility of bones ", " rheumatism involving the bone " category.Chinese medicine is thought, the pathogenesis of OP with suffer from a deficiency of the kidney, insufficiency of the spleen, blood stasis, stagnation of liver-QI have close relationship, wherein suffering from a deficiency of the kidney is that the pathogenesis of primary disease is crucial.Kidney storing essence, raw marrow of refining, marrow is supplemented nutrition in bone, the growth of skeleton, growth, withered and flourishing closely related with the vital essence prosperity and decline of kidney.Then bone marrow biochemistry is active for kidney essense abundance, and bone is nourished and strong; Deficiency of kidney-essence is the biochemical weary source of bone marrow then, and skeleton loses foster and paralysis is weak unable.Modern medicine by bone density, bone mineral content and sex hormone level and kidney deficiency correlation analysis, confirm the science that the traditional Chinese medical science " kidney governing bones " is theoretical equally.As can be seen here, deficiency of kidney essence is the pathogenesis that OP is the most basic, and the method for tonifying both YIN and YANG, kidney tonifying, essence replenishing bone strengthening is the fundamental law for the treatment of OP.
It should be noted that Chinese medicine decoction decocting bothers, decocting liquid volume be comparatively large, bitter in the mouth, take, carry inconvenience; And easy mouldy fermentation, should not store for a long time and prepare in a large number.Traditional Chinese patent medicine is as loose in kidney bone, the loose health-care composition of bone, Gu Yu Ling Capsules, Six-element bone-strengthening grain etc., these some dosage forms wherein not Portable belt or take, then flavour of a drug are more for some, and active constituent content is few, quality control standard is low, is difficult to obtain satisfied curative effect in clinical treatment.Modern Chinese medicine effective ingredient, as on-off total saponin as well as, Process of Total Flavonoids in Drynaria Fortunei, Herba Epimedii total flavones etc., although determined curative effect, quality controllable, acts on single, fails to embody the integrally-regulated idea of the traditional Chinese medical science.Therefore, based on traditional Chinese medicine theory, in conjunction with modern medicine theory and technology, develop a kind of effective ingredient clear and definite, determined curative effect, quality controllable anti-OP medicine is significant.
Herba Epimedii is kidney-nourishing yang-strengthening medicine, is the Chinese herbal medicine that treatment OP frequency of utilization is the highest.Large quantity research confirms, and Herba Epimedii and effective ingredient thereof effectively can improve biochemical markers of bone metabolism, corrects abnormal bone metabolism, reduce bone turnover rate, increase bone density, improve bone pathology state, promote experimental osteoporosis fracture repair, thus play anti-OP effect.Modern study shows that the mechanism of Herba Epimedii control OP is mainly summarised as following approach: 1. gonadotropic Effect.2. directly bone resorption and promoting bone growing is suppressed.3. contained anti-inflammatory component may affect bone metabolism.4. the various trace elements be rich in is formed with special role to osteoblast and ossein.5. act on bone matrix cell, promote the mineralising of collage synthesis and substrate.Herba Epimedii anti-OP effect is relevant with the Flavonoid substances contained by it, and it has mainly played class sex hormone function.
Fructus Ligustri Lucidi belongs to the medicine of the cloudy essence of conventional nourishing the liver and kidney, and have report, be that the tonifying kidney-yin class medicine of representative has good action equally to the treatment of OP with Fructus Ligustri Lucidi, its action intensity is not only close with Herba Epimedii, even may be better; Vitamin D sample active substance contained by it and estrogen-like product, can directly by maintaining calcium homeostasis in body to the expression of intestinal VDR and the regulation and control of calcium absorption; Be that the nourishing kidney yin recipe ERZHI WAN of principal agent can effectively alleviate the diseases such as postmenopausal osteoporotic patients Tidal fever with perspiration, insomnia and dreamful sleep and soreness of the waist and knees with Fructus Ligustri Lucidi, increase bone mineral density, bone mineral content, raise estradiol level, thus improve osteoporosis symptoms.The main component of its anti-OP is based on flavonoid, terpenoid.
Large quantity research confirmed single Herba Epimedii and Herba Epimedii and/or Fructus Ligustri Lucidi be correlated with compound recipe control OP in remarkable result, we are deficiency of kidney essence based on the basic pathogenesis of OP, select suitable dose ratio application Herba Epimedii, Fructus Ligustri Lucidi compatibility to prevent and treat OP in the clinical middle degree according to patient's kidney yang and deficiency of kidney-YIN, curative effect certainly.OP belongs to chronic complexity disease, palpus Long-term taking medicine, the unsuitable long-term clinical application of alone yang-tonifying drug Herba Epimedii character warm-dryness syndrome, if the Fructus Ligustri Lucidi of energy compatibility benefiting kidney-essence is with treating YANG within YIN, then can reach in " the new side eight of Jing Yue's complete work slightly " and say: " magical effect of this coordination of YIN and YANG also.”
