Can see that from table 2 three prescriptions tablet hardness, friabilities, disintegration, dissolution determination result are suitable.
Yet obvious redness is showed by discovery tablet appearance or edge regular meeting in the tablet press process that above-mentioned three prescriptions make, and prompting produces new impurity.
Find in the moxifloxacin hydrochloride raw material stability study that these product should not contact with metallic iron, especially cause moxifloxacin hydrochloride variable color (red by xanthochromia) under the wet heat condition.Moxifloxacin hydrochloride and iron content container or rustless steel drift in the preparation process, punch die contacts or rub the back changeable colour, for this reason, the granulation of said preparation, drying should avoid using the iron content container, and the granule of hydrochloric Moxifloxacin but is inevitable with contacting of drift and punch die in the tabletting process usually.
At present do not have any document that pharmacology, the toxicological effect of moxifloxacin hydrochloride raw material or its red impurity that produces in the tabletting process are reported to some extent as yet, can not predict it is harmless to human body.

The percentage by weight that used filmogen total amount accounts for described pharmaceutical preparation is 0.2~20.0%.
Further, to account for the percentage by weight of described pharmaceutical preparation be 0.5~10.0% to described filmogen total amount.
Described Moxifloxacin or its salt and/or its hydrate are meant moxifloxacin hydrochloride.
Described pharmaceutical excipient comprises starch, dextrin, pregelatinized Starch, microcrystalline Cellulose, carboxymethylstach sodium, cross-linking sodium carboxymethyl cellulose, micropowder silica gel, magnesium stearate, lactose.Wherein, lactose is optional in the present invention.
Because adopted above scheme, the beneficial effect that the present invention is possessed is:
Owing to used the listed filmogen of the present invention to be used to prepare intermediate particle, perhaps powder or granule are carried out coating, make moxifloxacin oral pharmaceutical preparation of the present invention, particularly tablet can retention properties be stablized in granulation and tabletting process, with iron content container or rustless steel drift, punch die contacts or rub after do not produce metachromatism, light, hardness is good, and the medicine stripping is rapid; And can ensure the quality of products after long-time the preservation yet, at room temperature place as label and can keep mass conservation in 2 years, hardness does not have remarkable change, color and luster and keeps yellow, dissolution all to remain on more than 90%.
The specific embodiment
But it is tabletting after adopting filmogen system granule or coating to granulate that the present invention obtains the method for stable Moxifloxacin or its salt and/or its hydrate tablet.The used film forming material can be hydroxypropyl emthylcellulose (HPMC), hydroxyethylmethyl-cellulose, methylcellulose, hydroxypropyl cellulose, hydroxyethyl-cellulose, sodium carboxymethyl cellulose, poly-(methyl) crylic acid resin (stomach dissolution type or stomach decentralized), Polyethylene Glycol, polyvinylpyrrolidone-vinyl acetate co-polymer (as
VA64 or
S-630), polyvinyl alcohol-polyethyleneglycol-graft copolymer (as
IR), the mixing of one or more in Ka Baibo (Carbopol), gelatin, the poloxamer.It is 0.2~20.0% that filmogen accounts for total tablet weight percentage ratio.
The using method of filmogen is as follows: can be made into aqueous solution or Diluted Alcohol solution prepares granule, its concentration is 0.5~10.0%; Also available part filmogen wiring solution-forming (concentration is the same) is made binding agent, remainder filmogen and principal agent and the mixed granule of other adjuvants, the filmogen that is used for wiring solution-forming does not have special restriction in the ratio of used filmogen total amount, when only needing to satisfy the solution that uses as binding agent and being mixed with granule, make mixture keep the humidity of necessity with remainder filmogen, principal agent and other adjuvants; Whole filmogens can also be mixed with principal agent and other adjuvants, water or Diluted Alcohol are made granule after making suitable soft material; And can carry out coating to the powder or the granule of Moxifloxacin with filmogen solution.Described Diluted Alcohol is used 30%~50% ethanol always.
Granulation and drying can adopt conventional method.As the mixed at high speed granulation, or ebullated bed granulation seasoning.
Medicine is resolved by using filmogen and above-mentioned method of granulating with metal drift, the edge variable color of the fricative tablet of punch die in the tabletting process.
Pharmaceutical preparation of the present invention can also contain an amount of excipient, this excipient can be selected from following adjuvant, and they are starch, dextrin, pregelatinized Starch, microcrystalline Cellulose, carboxymethylstach sodium, cross-linking sodium carboxymethyl cellulose, micropowder silica gel, magnesium stearate, lactose.Also can not contain lactose.
