Because emplastrum is percutaneous drug administration preparation, medicine need penetrate into body by keratodermatitis etc., generation effect, and therefore generally onset time is longer, conventionally adopts and adds penetrating agent to promote drug osmotic.But general chemical enhancers has certain side effect, life-time service may cause skin discomfort, lumbago plaster of the present invention adds far-infrared powder and magnetic powder in adjuvant, the far infrared that far-infrared powder produces claims again " life light wave ", approach with the frequency of vibration of human inner cell's molecule, after in it infiltrates body, just can cause the resonance of atom and the molecule of human body cell, seeing through sympathetic response absorbs, between molecule, frictional heat forms thermal response, impel subcutaneous deep temperature rise, and make Marjoram Extract, accelerate blood circulation, can promote the absorption of medicine, reduce penetrating agent consumption.
In addition, lumbago plaster of the present invention adds after far-infrared powder and magnetic powder in adjuvant, depths, the deep and thorough Li Keda muscle joint of far infrared, make body interior warm, relax one's muscles, drive the oxygen of capillary network and nutrient exchange, and it is interior swollen to eliminating to get rid of the aging refuses such as the tired material that accumulates in body and lactic acid, relaxes the effect brilliance of aching.Specific electromagnetic wave spectrum (TDP) wavelength that magnetic powder produces, at 2-25 micron, is easy to be absorbed by organism, and is free from side effects.Can also produce the biological effect useful to biology, thereby improve the activity of various enzymes in organism, improve the microcirculqtory system in organism, improve and transfer the immunologic function of organism self, produce more immune body fluid, alleviate pain disease.Far-infrared powder and magnetic powder can promote the quick absorption of medicine simultaneously, improve the utilization rate of medicine, thus make lumbago plaster onset of the present invention rapidly, good effect.
Compared with prior art, the present invention is with Radix Et Rhizoma Rhei, Rhizoma Zingiberis, Rhizoma Kaempferiae, the Radix Aucklandiae, the Radix Cynanchi Paniculati of antalgic and inflammation relieving, and the Cortex Periplocae of wind-expelling pain-stopping, Rhizoma Chuanxiong, Radix Cyathulae, Radix Angelicae Pubescentis, the Radix Angelicae Dahuricae, Heiguteng exract, help Radix Dipsaci, Lignum Santali Albi, Flos Caryophylli composition with warming the kidney to activate YANG.Both be good at the lumbago that chronic strain and aseptic inflammation cause, be good at again treating the arthralgia pain due to rheumatism.We have added far-infrared powder and magnetic powder in adjuvant simultaneously, the depths, the deep and thorough Li Keda muscle joint of far infrared that far-infrared powder produces, make body interior warm, relax one's muscles, drive oxygen and the nutrient exchange of capillary network, and it is interior swollen to eliminating to get rid of aging refuses such as accumulating tired material in body and lactic acid, the effect brilliance that mitigation is ached, far infrared can make subcutaneous deep skin temperature-elevating simultaneously, expansion blood capillary, blood circulation promoting, is conducive to the infiltration and usage of medicine.The specific electromagnetic wave spectrum that magnetic powder produces is easy to be absorbed by organism, the biological effect that generation is useful to biology, thereby the activity of various enzymes in raising organism, improve the microcirculqtory system in organism, improve and transfer the immunologic function of organism self, produce more immune body fluid, diminish inflammation and pain disease.
Applicant has carried out following experiment, and provable the present invention has effective effect;
Experimental example 1:
Medicine of the present invention adopts 90% ethanol for extracting solvent, and inventor finds through Related Experimental Study, uses cold-maceration to extract, and ethanol large usage quantity is extracted not exclusively, uses percolation to extract, and has ethanol consumption less, the advantage such as extracts more completely.Use the lumbago plaster outward appearance that lumbago plaster adjuvant of the present invention is write out a prescription and production technology is produced, the property pasted, uniformity etc. all better.
1, matrix optimization
The evaluation methodology of 1.1 emplastrum substrate
With indexs such as outward appearance, viscosity, stretchability, uniformity, fissilities, made emplastrum substrate is carried out to overall merit: outward appearance should be the paste that rare denseness is suitable; Viscosity is take skin as experimental subject, and stickiness should be larger; Stretchability should be easy to coating; It is consistent without granular sensation, exquisiteness, thin and thick when uniformity should be coated with on non-woven fabrics; Fissility is tackled plastic covering film and is easily peeled off, do not stick.All items is evaluated by index quality, 20 points of full marks, and defective is 5 points, obatained score summation is comprehensive grading.
The optimization of 1.2 emplastrum substrate prescriptions
According to emplastrum prescription and principal agent characteristic, by experiment of single factor, selecting C5 hydrogenation, naphthenic rubber oil, SIS-818 and SBS-811 is substrate constituent, inventor is take C5 hydrogenation, naphthenic rubber oil, SIS-818 and SBS-811 as investigation factor, each factor is established 3 levels, factor level, in Table 1, is selected L

2, penetrating agent consumption is investigated
2.1 emodin contents are measured
Chromatographic condition and system suitability: octadecylsilane chemically bonded silica is filler; Take methanol-0.1% phosphoric acid solution (85:15) as mobile phase; Detection wavelength is 254nm.Number of theoretical plate calculates and should be not less than 3000 by emodin peak.
The preparation of reference substance solution: it is appropriate that precision takes emodin reference substance, adds methanol and makes respectively every lmL containing the each 80 μ g solution of emodin, obtains.
Algoscopy: accurate reference substance solution and the each 10 μ L of need testing solution of drawing respectively, injection liquid chromatography, measures, and obtains.
2.2 test sample skin permeation rates are measured: the lumbago plaster of the present invention of same homalographic and blank patch are affixed on respectively to 2 pretreated Corium Mus surfaces, paste powder and be installed on transdermal diffusion experiment instrument towards supply chamber, acceptable solution is normal saline.Setting bath temperature is (37 ± 0.5) ℃, mixing speed 100r/min, respectively at the the the 2nd, 4,6,8,12 and 24h sampling, take blank patch acceptable solution as blank, by " 5.3.1 ", measure, calculate the content that transdermal enters the emodin in absorption cell, and be calculated as follows test sample skin permeation rate, emodin in skin permeation rate (%)=absorption cell
aemodin total amount × 100% in content/lumbago plaster.
2.3 result
Add not commensurability penetrating agent to affect as table 3 emodin skin permeation rate:
Table 3 emodin skin permeation rate
2.4 conclusions: as seen from the above table, emodin skin permeation rate increases with penetrating agent consumption, when penetrating agent consumption exceedes after 5g, emodin skin permeation rate is almost constant, therefore penetrating agent consumption is 5g.
Experimental example 2: pharmacodynamic study
