As the further improvement of foregoing invention, in step 4, the weight ratio of solid dispersion, diluent, correctives, wetting agent is 100:10 ~ 15:4 ~ 8:0.5 ~ 1.2.
As the further improvement of foregoing invention, described diluent is starch, dextrin, maltose or lactose.
Due in digestion, the physiological pH from stomach to intestinal raises gradually.After which results in drug administration, although dissolve in the stomach, after gastric emptying enters intestinal, along with the rising of pH, the medicine of dissolving will separate out precipitation.A large amount of precipitations of medicine, make it can not remain in intestinal juice with molecularity, cannot realize cross-film and absorb, thus affect the absorption of medicine, bioavailability is reduced.Therefore, should pharmaceutics means be passed through, improve the dissolubility of medicine and drug loading, avoid its precipitation in neutral medium, thus improve the bioavailability of medicine.
At present, improve the method for insoluble drug dissolubility and dissolution, mainly contain micronization technology, inclusion technique and solid dispersions technique etc.Now there are some researches show, after drug micronization, particle diameter reduces, and surface area increases, and dissolution increases.But particle diameter is reduced to a certain degree, microgranule free energy sharply increases, and in storage process or enter after in body, have the trend of self-assemble, dissolution reduces on the contrary.And inclusion technique is owing to being subject to the restrictions such as drug molecule amount, space structure, success rate is lower, i.e. enable successful enclose, also there is the problems such as drug loading is low.
Solid dispersions technique, in raising insoluble drug dissolubility and dissolution, has more research and more significant effect.But also there is some complex process, the problems such as drug loading is low.Especially want to obtain positive effect, often need to apply a large amount of carriers, this must result in the lower drug loading of solid dispersion.For the medicine of those large usage quantities, even if after being prepared into solid dispersion, drug solubility and dissolution all significantly improve, but lower drug loading necessarily limit the dosage form being prepared into applicable clinical needs.And if solid dispersion needs to be prepared into oral solid formulation further, the dry jet mixing pile that self is poor, often also can limit it and apply further.
Solvent method prepares solid dispersion, and the method removing organic solvent generally has drying under reduced pressure, spraying dry and lyophilization.Freeze-drying is high to equipment requirements, and production cost is high, general little application.At present, drying under reduced pressure and spraying dry are most widely used.And product prepared by spray drying method often has better dissolubility, it is made to apply day by day extensive.But, the beat all discovery of the present inventor, by active component and respective carrier, with the solid dispersion that this two kinds of drying meanss are prepared into, dissolubility do not have significant difference, but the dry jet mixing pile of the solid dispersion prepared with hypobaric drying method (compressibility and mobility), is but obviously better than the product that spray drying method is obtained.
The present invention, by Chinese medicine extract and macromolecule carrier are prepared into amorphous solid dispersion by solvent method, drastically increases the drug loading of medicine.After removing organic solvent by the method for drying under reduced pressure, obtained solid dispersion, dry jet mixing pile is good, and mobility and compressibility are all better than solid dispersion prepared by prior art, can be prepared into the dosage form being convenient to clinical practice.
The present invention, by improving the preparation technology of Er'bao granule, on the one hand, decreases supplementary product consumption, and infant dose reduces, and significantly improves Compliance; On the other hand, effectively eliminate the impurity affecting main constituent storage stability, improve the stability of granule.
