It is a kind of to be used to treat pharmaceutical composition of gout and preparation method thereof
Technical field
The invention belongs to the field of Chinese medicines, and in particular to a kind of for treating pharmaceutical composition of gout and preparation method thereof.
Background technology
Gout (Gout) refers to disease caused by the purine metabolic disturbance caused by a variety of causes and/or underexcretion
Disease can lead to the recurrent exerbation of acute arthritis, uric acid with the characteristics of forming Monosodium urate crystallization in joint part and its hetero-organization
Sodium crystallization can further form bulk, form tophus, cause chornic arthritis, joint deformity, or even can lead to function of joint
Forfeiture, uric-acid calculus can also be generated in kidney, and gouty nephropathy is caused to become.Gout be apt to occur in 40-50 Sui male and absolutely
Women after menstrual period, but age of onset is gradually to the development that becomes younger.According to epidemiological study, China suffers from high lithemia at present
The patient of mass formed by blood stasis alreadys exceed 100,000,000 people, and is diagnosed as the patient of gout nearly 20,000,000 people, and also left with annual 10%
Right speed increase, patient suffering can't bear when gout is broken out, and become one of the disease for seriously affecting people's live and work.
Doctor trained in Western medicine using anti-inflammatory analgetic class drug, inhibits uric acid shape for the treatment of gout generally from its symptom at present
Class drug etc. is drained at class drug or uricosuric, is only capable of alleviating the clinical symptoms of gout to a certain extent, takes stopgap measures and cannot control
This, and needs Long-term taking medicine to alleviate symptom, is quickly recurred after drug withdrawal, and not only therapeutic effect is limited, can also give patient with
Come serious drug side-effect, such as Nausea and vomiting, indigestion, headache, dizziness.
Chinese medicine thinks that gout belongs to the scope of traditional Chinese medicine " rheumatism ",《Plain Questions numbness opinion》A piece points out " so-called numbness person, respectively with it
When, the wet gas of being affected wind-cold repeatedly ", the transient cause that rheumatism occurs has that " three gas of wind, cold, wet is miscellaneous extremely, combined into numbness.Its general mood wins
Person is migratory arthralgia, and BI-syndrome caused mainly by pathogenic cold being called painful BI, moisture victor is numbness." gout exists by ZHU Dan-xi first as name of disease《Further Discourses on the Properties of Things》
Middle proposition, " gout and pain has a normal place, sore spot is red swollen scorching hot, or high fever from head to foot ", and propose " with hot agent, cold-dampness of scattering,
Develop space between skin and muscles, blood must be capable " gout treatment principle.Later age Chinese medicine doctor to the etiology and pathogenesis of gout carried out supplement and it is rich
It is rich, it is believed that the etiology and pathogenesis of gout includes:Insufficiency of natural endowment, caused by liver and kidney deficiency, Ying Wei become estranged, deficiency of vital energy and blood, phlegm wet numbness hinder, in gout
Sick initial stage positive unsaturated vapor, causes to invade in exopathogen, stops up resistance channels and collaterals, and QI-blood circulation is unsmooth, and wind-cold-dampness arthralgia resistance increases.The liver belonging to wood, kidney category
Water, regulation between water and fire, the two share success, and a damage is all damaged.If caused by liver and kidney deficiency, also virtual loss, muscles and bones lose foster, the laboured breathing of liver kidney to essence and blood
It is weak, then susceptible wind-cold damp pathogen and fall ill.Defend gas and be primarily referred to as function basis in traditional Chinese medicine scope --- outside defending, defend, and ying blood
It is mainly then material base, the two can influence each other again, mutually restrain;From sick position, gas is defended in table, and ying blood is in inner, gas
For the general of blood, blood being the material foundation of QI, blood contains that then gas is prosperous, and the prosperous then blood of gas is contained, gas row then blood, and the stagnation of the circulation of vital energy then blood stasis, battalion, which defends, to become estranged then easily
Feel exopathogen, exopathogen invasion easily causes QI-blood circulation unsmooth, and tendon and vessel, which is lost, supports.For the treatment of gout, successively there is gout and dissipate, bitterly
Wind soup, SIMIAO WAN, Simiao San plus-minus plus taste Punching line etc., achieve certain therapeutic effect, but still undesirable.
Present inventor provides one kind on the basis of having studied existing gout etiology and pathogenesis and the therapy rules for the treatment of comprehensively
Effect preferably treats the pharmaceutical composition and preparation method thereof of gout.
