Abstract
The invention relates to a diclofenac sodium osmotic-pump controlled-release preparation and a preparation method thereof. The preparation is composed of an osmotic pump tablet core and a semipermeable controlled-release coating coated outside the tablet core, wherein the osmotic pump tablet core comprises a main drug, permeable active substances, a binding agent, a cosolvent, a filler and a lubricant; and the semipermeable controlled-release coating comprises a coating material, a pore-forming agent and a plasticizer. The invention also relates to a preparation method of the osmotic-pump preparation. The preparation technique is simple, and adopts a conventional tablet preparation method; the tablet core is pressed by a conventional method without determining the punching surface; and by using the osmotic pressure between the inner and outer sides of the semipermeable membrane as driving force, the preparation releases the drug at zero-level release rate to maintain the stable blood concentration in vivo, has the characteristics of moderate drug in-vivo action time and low side effect, and can not easily generate drug resistance after repeated administration. The invention can reduce the drug taking frequency, and enables the drug absorption to be free from the influence of food intake and in-vivo environment, thereby enhancing the compliance of the patient.
Description
Technical field
The invention belongs to technical field of medicine, relate to diclofenac sodium osmotic pump type controlled release preparation and preparation method thereof.
Background technology
Diclofenac sodium is third generation NSAID (non-steroidal anti-inflammatory drug), and in body, Cycloxygenase suppresses arachidonic synthetic to this product by suppressing, and makes the synthetic minimizing of prostaglandin; Simultaneously, it also can promote arachidonic acid to be combined with triglyceride, reduces the arachidonic acid concentration of endocellular liberation, and indirectly suppresses the synthetic of leukotriene, thereby plays rheumatism, antiinflammatory, pain relieving and refrigeration function.Be usually used in clinically antiinflammatory and the analgesia of osteoarthritis, bursitis, rheumatic arthritis, tendinitis and other joint or periarticular disease.Its antiinflammatory, refrigeration function are strong 9 times than indometacin, than the strong 26-50 of aspirin doubly.Have in similar drugs because of it that good effect, side effect are little, prolonged application is without advantages such as savings property, now use more than 40 countries and regions, be one of world's best-selling drugs.
The diclofenac sodium oral absorption is fast, complete; Reduce absorbance with food with clothes.Average 1~2 hour peaking of blood drug level auf nuechternen Magen einnehmen, 6 hours peakings when taking with food is same, the short (T of biological half-life
1/2Be 1.5h), plasma protein binding rate is 99%.
Because its biological half-life is short, want to keep its effective blood drug concentration, common oral preparation needs frequent drug administration, and blood concentration fluctuation is large, and patient dependence is poor, is unfavorable for clinical treatment; Though its slow releasing preparation is taken rear blood concentration fluctuation and is improved, belong to non-zero order and discharge, still not ideal enough.Existing dosage form can not adapt to needs clinically far away, and exploitation controlled release preparation once-a-day meets the needs of clinical development.Take the osmotic pump type controlled release tablets of osmotic pressure as main release power, can keep constant permeable pressure head in external setting-up time in tablet, for discharging, the medicine zero level of meeting water dissolution or even suspendible in tablet provides constant release power.The constant release of medicine has effectively been avoided the peak valley phenomenon of blood drug level in body, when keeping medicine and effectively treating concentration, has overcome the drug side effect that causes because of peak concentration.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in existing preparation technique, a kind of diclofenac sodium osmotic pump type controlled release preparation is provided, it is mainly diclofenac sodium mono-layer osmotic pump sheet, can effectively adjust drug release rate, obtain comparatively steady and effective blood drug level, thereby reduce drug side effect and medicining times, improve patient compliance.
Purpose of the present invention can reach by following measures: the present invention includes the label that contains diclofenac sodium and be wrapped in the label semi-transparent coating membrane of controlled release of drug release hole in addition, described coating membrane weight is the 3%-10% of label weight; Described drug release hole is in tablet surface one or both sides laser boring and/or machine drilling.

Described lubricant is: one or more of Pulvis Talci, magnesium stearate, micropowder silica gel, hydrogenated vegetable oil, Polyethylene Glycol apoplexy due to endogenous wind.
Described semipermeable membrane coating material is: one or more in cellulose acetate, ethyl cellulose, acrylic resin, acetylbutyrylcellulose, polyvinyl alcohol.Porogen is selected: a kind of in PEG400, PEG1500, PEG4000, PEG6000.Plasticizer is selected: one or more in glycerol, propylene glycol, Polyethylene Glycol, phthalic acid ester, triglyceride.
Described punching technology is that the hole that one or two diameter is the 0.2-1.4 millimeter is beaten in laser boring or machine drilling.
Diclofenac sodium osmotic pump tablet preparation method is as follows:
(1) supplementary material is crossed respectively 100 mesh sieves, and the supplementary material except lubricant is crossed 60 mesh sieve mix homogeneously, the soft material processed take the 10%PVP ethanol solution as binding agent, and 20 mesh sieves are granulated, 40 ℃ of dryings, 18 mesh sieve granulate add lubricant to be pressed into label.
(2) semipermeable membrane coating material and plasticizer, porogen are dissolved in solvent, magnetic agitation makes it to become uniform solution; Label is put coating pan with the certain pressure spray coating, art for coating: spray velocity 3-4ml/min, 40-50 ℃ of coating kettle temperature, coating pan rotating speed 30-35r/min, coating to the label 3%-10% that increases weight puts coated tablet and removes residual solvent in air dry oven, solidifies 12 hours;
(3) use laser or mechanical means to prepare the aperture of a diameter 0.2-1.4 millimeter in one or both sides, gained coated tablet surface, namely get the diclofenac sodium osmotic pump type controlled release tablets.
Advantage of the present invention is: the film control techniques of application of advanced, diclofenac sodium is made mono-layer osmotic pump type controlled release tablet.Compare with ordinary preparation, this preparation only needed be administered once in one day, and effect is lasting, stable curative effect, and toxic and side effects is little, reduces medicining times, improves patient's compliance.Said preparation is not affected by the factors such as gastrointestinal motility, pH value, gastric emptying, and the hook good relationship is released in the inside and outside.
