Background technology
Clopidogrel is as the antiplatelet drug of a new generation, in liver, become active metabolite through the Cytochrome P450 biotransformation, optionally suppress adenosine diphosphate (ADP) (ADP) and its combining and the activation of the glycoprotein GP II b/III a complex of the ADP of secondary mediation of platelet receptor, thereby suppress hematoblastic gathering.Be used for the treatment of restenosis and thrombotic complications etc. in atheromatosis, acute coronary artery syndrome, the prevention intracoronary stent implantation after-poppet clinically.
Chlorine pyrroles thunder is with the form administration of disulfate, and disclosed at present chlorine pyrroles thunder preparation has tablet, capsule, drop pill, injection.Do not see the pertinent literature report of clopidogrel hydrogen sulfate dispersible tablets as yet.Chlorine pyrroles thunder is almost insoluble in neutral water, and easily forms the bigger insoluble aggregate of viscosity after meeting water, so its solid preparation easily causes content inhomogeneous when wetting agent carries out wet granulation using water as.Also exist chlorine pyrroles thunder to be degraded to the problem of chlorine pyrroles fulminic acid in addition.Point out among the patent US6914141 that magnesium stearate lubricant can cause the degraded of bisulfate clopidogrel with clopidogrel generation interaction.Chinese patent CN200610063151.7 discloses solid preparation of a kind of chlorine pyrroles thunder sulfate and preparation method thereof, use glycerol Palmic acid stearate to solve the problem that chlorine pyrroles thunder is degraded to chlorine pyrroles fulminic acid in the component, but effect is not satisfactory as lubricant.Compressing dry granulation is adopted in the preparation of its tablet, for medicine is mixed fully, added a large amount of adjuvants and finally made the tablet that specification is 25mg by very complicated technology, this can increase drug manufacture cost and cycle undoubtedly, chlorine pyrroles thunder sheet conventional taking dose clinically is 75mg/ time in addition, be equivalent to 25mg specification tablet and need once take three, obviously be unfavorable for improving patient's compliance.Conventional tablet is often because of disintegrate and the slow abundant absorption that influences medicine of stripping in the existing dosage form; Though liquid preparation absorbs fast, need injection, use is inconvenient, and poor stability, packing, transportation is stored equal inconvenient.Therefore be necessary to develop a kind of novel chlorine pyrroles thunder preparation.
Summary of the invention
The purpose of this invention is to provide a kind of clopidogrel hydrogen sulfate dispersible tablets and preparation method thereof, it is reasonable that it has component, technology is simple, disintegration time is short, the medicine stripping rapidly, absorb fast and can improve the characteristics of drug bioavailability, also make old man, the difficult patient that swallows and taking medicine in water-stressed conditions become more convenient simultaneously.
For achieving the above object, the present invention adopts following technical scheme:
A kind of clopidogrel hydrogen sulfate dispersible tablets, contain following component by weight percentage:
Clopidogrel hydrogen sulfate 30~55%
The adjuvant surplus.
Preferably:
Clopidogrel hydrogen sulfate 35~45%
Adjuvant 55~65%
Wherein, described adjuvant comprises disintegrating agent, filler, lubricant, correctives.
Disintegrating agent is selected from one or both the mixture in low-substituted hydroxypropyl cellulose, the cross-linking sodium carboxymethyl cellulose, and accounting for total weight percent is 5~20%.Add in when disintegrating agent can mix or add during tabletting or inside and outsidely all add.
Filler is selected from one or more the mixture in lactose, mannitol, microcrystalline Cellulose, the pregelatinized Starch, and accounting for total weight percent is 25~60%.
Lubricant is selected from one or both the mixture in stearic acid, castor oil hydrogenated, the micropowder silica gel, and accounting for total weight percent is 1~5%.
The preparation method of clopidogrel hydrogen sulfate dispersible tablets can be direct powder compression and wet granulation process.
1, direct powder compression: with tabletting behind bisulfate clopidogrel and filler, disintegrating agent, lubricant and the sweeting agent mix homogeneously.
2, wet granule compression tablet method: bisulfate clopidogrel and filler are mixed, do not add or add part or all of disintegrating agent, correctives mixing, add binding agent and make soft material, granulate 40~50 ℃ of oven dry, granulate, add in addition part or all of disintegrating agent, add the lubricant mixing again, tabletting.Wherein binding agent adopts a kind of in the alcoholic solution of hydroxypropyl emthylcellulose or tween 80 or their mixture.
In the preparation of described clopidogrel hydrogen sulfate dispersible tablets, raw material, adjuvant all needed 80 mesh sieves.
Preparation technology's preferred version is: raw material and other adjuvants crossed 80 mesh sieves respectively, takes by weighing clopidogrel hydrogen sulfate, filler, disintegrating agent, lubricant and sweeting agent, mix the back after 80 mesh sieves twice by the equivalent incremental method by group component, and tabletting, promptly.
In the experimental study process, the present invention has carried out investigating checking respectively to the preparation technology of wet granule compression tablet and direct powder compression.The result is presented in the wet-granulation process clopidogrel hydrogen sulfate and meets and promptly be clamminess behind the water and can produce aggregation, adopts binder aqueous solution to granulate easily to cause the tablet content of being suppressed inhomogeneous, and correspondingly, the dissolution homogeneity is also relatively poor.Find in the experimentation that when using ethanol instead and making wetting agent, the viscosity of medicine wet granular obviously reduces, pelletization is easier to relatively.For the dissolubility that improves medicine and help molding particles, the present invention adopts the alcoholic solution of hydroxypropyl emthylcellulose or tween 80 to make binding agent, the dispersing uniformity of chlorine pyrroles thunder dispersible tablet and dissolution all be improved significantly.Adopt the technology of direct powder compression comparatively simple, solvent contact not in preparation process also need not heating, has therefore correspondingly improved stability of formulation.But direct powder compression is had relatively high expectations to the flowability of adjuvant, need reach certain fluidity after supplementary material mixes and just can not cause bigger tablet weight variation.
Disintegration rate is the key parameter of dispersible tablet, so the selection of disintegrating agent is extremely important.The present invention has carried out great deal of experimental to the kind and the consumption of disintegrating agent in the component.On the technical foundation of existing bibliographical information, carboxymethyl starch sodium, low substituted hydroxy-propyl methylcellulose, several disintegrating agents of cross-linking sodium carboxymethyl cellulose have been investigated respectively.The result shows, for after the disintegrating agent tabletting places a period of time, tablet can turn to be yellow with the carboxymethyl starch sodium.Study on Compatibility by supplementary material is found, with chlorine pyrroles thunder and carboxymethyl starch sodium powder mixes put place ten days under influence factor's condition after, powder can be become brown by original white, and with the most obvious under the hot conditions, so disintegrating agent carboxymethyl base Starch Sodium is got rid of.Through repetition test, determine that finally preferred disintegrating agent is one or both or the mixture in low-substituted hydroxypropyl cellulose, the cross-linking sodium carboxymethyl cellulose, accounting for total weight percent is 5~20%.And when the percentage ratio consumption of disintegrating agent is controlled in 7~15% scopes, the dispersing uniformity of its dispersible tablet and dissolution the best.
In addition, there is document to show that the clopidogrel hydrogen sulfate preparation can produce the problem of chlorine pyrroles thunder degraded when using magnesium stearate to make lubricant.Therefore, the present invention has also made Preliminary screening to the use of lubricant, respectively stearic acid, fumaric acid sodium stearate, three kinds of lubricants of castor oil hydrogenated is investigated.Find that in the compatibility test of supplementary material the fumaric acid sodium stearate uses the problem that the degraded variable color can occur with clopidogrel hydrogen sulfate.And stearic acid, castor oil hydrogenated and clopidogrel hydrogen sulfate compatibility are more stable after using, and significant change does not all take place characters powder, and its preparation is all up to specification through content and determination of related substances.
In sum, good effect of the present invention is, disintegrating agent kind and consumption are being carried out on the basis of screening and optimizing, technology by comparatively simple directly pressed powder or wet granule compression tablet is made stable clopidogrel hydrogen sulfate dispersible tablets, its production technology does not need special installation, production cost is lower, and compares with conventional tablet, has more superior disintegrate and dissolving out capability.
