Description
Technical field
The present invention relates to a kind of Bu Waxitan preparation, be specifically related to a kind of Bu Waxitan oral cavity disintegration tablet and preparation method thereof.
Background technology
Epilepsy is a kind of long-term chronic brain diseases, be the unexpected abnormal excessive of brain cell caused by cerebral lesion discharge cause brain function imbalance syndrome.At present, antiepileptic can be divided into three generations according to development history, and first on behalf of traditional classical AEDs, comprises phenytoin Sodium, carbamazepine and western natrium valericum etc.; Second on behalf of modern AEDs, comprises phenytoin Sodium, carbamazepine, levetiracetam and adds spray fourth etc.; The third generation is new A EDs, comprises Bu Waxitan, carabersat, retigabine etc.Bu Waxitan wherein, by the inhibitory action of SV2A height affinity interaction and sodium-ion channel, significantly improve antiepileptic activity, the good toleration aspect with good safety and pharmacokinetics, particularly central nervous system is obviously better than other antiepileptic.
Existing Bu Waxitan medicine, mainly comprising slow releasing tablet, is that the application for a patent for invention file of CN201410407641.9 discloses a kind of prolongation delivery formulations containing 2-OXo-1-pyrrolidine derivatives as the application number application for a patent for invention file that is CN200980120221.X discloses a kind of pharmaceutical composition, application number comprising Brivaracetam; Application number is that the application for a patent for invention file of CN200980145588.7 discloses a kind of prolongation delivery formulations comprising 2-OXo-1-pyrrolidine derivatives; Application number is that the application for a patent for invention file of CN200980145828.3 discloses a kind of prolongation delivery formulations containing 2-OXo-1-pyrrolidine derivatives; Application number is that the application for a patent for invention file of CN201410370727.9 discloses a kind of prolongation delivery formulations comprising 2-OXo-1-pyrrolidine derivatives.
But, the patient of epilepsy shows as unexpected unconsciousness and whole body convulsive seizure mostly, or show as unexpected disturbance of consciousness and muscular tension disappearance, or to show as head and muscle of upper extremity be that main bilateral rhythmicity myoclonus is twitched, or in status epilepticus (show as persistence outbreak or recurrent exerbation companion intermission consciousness function do not recover), therefore Bu Waxitan is prepared as the ordinary tablet or slow releasing tablet that need to swallow, the compliance that patient takes is very poor, even may block trachea, there is potential danger.
Summary of the invention
The object of the present invention is to provide and a kind ofly take safety, disintegrating property is good, mouthfeel is good a kind of Bu Waxitan oral cavity disintegration tablet, the present invention also provides the preparation method of this Bu Waxitan oral cavity disintegration tablet.
For solving the problem, the technical solution adopted in the present invention is as follows:
A kind of Bu Waxitan oral cavity disintegration tablet, it is prepared material and comprises following component according to parts by weight: Bu Waxitan 18-32 part, has disintegrating agent 2-10 part of fast disintegration property, hydrophilic filler 30-75 part, correctives 1.45-4 part, at least one in lubricant and fluidizer; Described lubricant is 0.2-1.5 part, and described fluidizer is 0.5-2.5 part.
