Abstract
The present invention relates to a kind of methods for preparing particle, it is characterised in that stirs cortin particle in the ethanol water that concentration is 4-10%, grain diameter can be made to reduce by 20% or more.
Description
Technical field:
The present invention relates to a kind of methods that organic water solvent reduces corticosteroid drug partial size, are obtained using this kind of method
Particle can use in pharmaceutical preparation, so that pharmaceutical preparation has better effect.
Background technique
It is well known that glucocorticoid has good effect in treatment inflammation.Glucocorticoid is both normal human
Interior important physiologically substance, and be the immunosuppressor of wide clinical application.In vivo, it is secreted by adrenal cortex glomerular zone
Steroid hormone mainly includes cortisol and cortisone.The clinical glucocorticoid used as drug mainly includes hydrogenation can
Pine, prednisone (prednisone), dexamethasone etc., wherein influence of the dexamethasone to normal endogenous cortisol secretion is the most aobvious
It writes.The pharmacological action of glucocorticoid mainly includes anti-inflammatory, immunosupress, Hemorrhagic shock and antitoxic action.Although glucocorticoid
It is had longer history as anti-inflammatory drug and immunosuppressor in clinical application, curative effect gains public acceptance already, in idicatio, agent
Amount, side effect etc. have accumulated considerable clinical data.Using glucocorticoid as the local injection group of active constituent
Object is closed, can treat muscle skeleton and soft tissue disease: rheumatoid arthritis, such as osteoarthritis, bursal synovitis, tatanic ridge
Vertebra is scorching, epicondylitis, radiculitis, coccyalgia, sciatica, pain in the loins, torticollis, ganglion, epostoma, fascitis etc.
Disease.
The third section 1-4 row of page 261 discloses that " drug in general powder unless otherwise specified should all in evidence 2
Pass through No. six sieves after crushing.Slightly solubility and the slow drug such as salol, camphor, sulfanilamide (SN) etc. of dissolution rate should crush carefully a bit to increase
Add dissolution rate, to improve curative effect；Most fine powder must be made in secondary magnesium carbonate, aluminium hydroxide etc., give full play to its treatment with benefit
Effect；", " solubility of insoluble drug is described in influence of (two) powder physicochemical property to preparation validity of page 237
And dissolution rate absorption of drugs has an impact.The dissolution of insoluble drug is related with its specific surface area, the small then specific surface of particle
Product is big, and solubility property is good, therefore can improve its curative effect.", the evidence page 437 " 3. granularity " partially discloses that " indissoluble or dissolution are slow
Slow drug, partial size are to influence an important factor for absorbing.Partial size is thinner, and surface area is bigger, and solution rate is faster." thus may be used
See, the evidence 2 enlightened for the drug of slightly solubility can by reduce particle so that be reduced to 10 μm hereinafter, molten to increase
Xie Du, to improve the absorption of drug.
It is known that the medicine material medicine usual manner for obtaining lower partial size is to crush.Crushing process be solid material outside
Under power effect, the process that overcomes cohesive force that particle is made to become smaller.There are many kinds of this external force, such as electric power, mechanical force, explosion.Just
For mechanical force, basic grinding mode, which has, squeezes crushing, impact comminution, fricting shearing crushing and splitting crushing etc..
But due to using external force in crushing, it will cause particle heating, under the action of internal residual moisture, can generate miscellaneous
The problems such as matter increases, while will also result in a series of environmental issues such as the excessive, dust of energy consumption.

The ester of above-mentioned glucocorticoid, it is characterised in that the acid of the 1-5 carbon is acetic acid, propionic acid, butyric acid, isobutyl
One or more of acid, valeric acid, furancarboxylic acid.
The above-mentioned method for preparing cortin particle, it is characterised in that the ethanol content of the ethanol water is 5-
8%.
The above-mentioned method for preparing cortin particle, it is characterised in that the solubility of the cortin in water is micro-
It is molten, almost insoluble or insoluble.
The application of particle obtained by the above method in medicine preparation.
Particle obtained by the above method is preparing the application in Sucked medicine.
Particle obtained by the above method is preparing the application in oral administration solid drug.
Particle obtained by the above method is preparing the application in external drug.
Application of the particle obtained by the above method in preparation injection drug.
Specific embodiment
Below will by embodiment, the invention will be further described, these description be not the content of present invention is made into
