A kind of fater disintegration type nicergoline tablets and preparation method thereof
Technical field
The invention belongs to technical field of medicine, are related to a kind of preparation method of fater disintegration matrix agent, and in particular to
The preparation method of fater disintegration type nicergoline tablets.
Background technique
With the aging of population of society, memory and cognitive decline are the inevitable physiological phenomenons of normal aging, and are crazy about
Slow-witted, mild cognitive impairment and normal aging occur from cognitive decline state different degrees of in the elderly, the nervous system disease
Have become the big killer for threatening human health.By taking dementia as an example, senile dementia is also known as Alzheimer disease, has become
The fourth-largest killer of the elderly after cardiovascular disease, malignant tumour, cerebral apoplexy.The disease is a kind of primary degeneration brain
Disease occurs in Senectitude and presenium, and increases with the age and be multiplied, and over 60 years old, illness rate was 4%~8%, 65
It can be more than 30% after increasing to 10%, 80 years old after year.And patient's number of Aged in China dementia is also in significant ascendant trend, according to system
Meter, patient populations occupy first place in the world there are about 6,000,000 at present, and about 1/4 in China in global patient.
Nicergoline is semi-synthetic ergoline derivatives.With alpha-receptor retardation and vasodilative effect.It can reinforce brain
The metabolism of cellular energy increases the utilization of oxygen and glucose.Promote the conversion of neurotransmitter dopamine and increases nerve
Conduction reinforces the synthesis of brain protein, effectively improves memory and learning ability, restore neurogenous normal function and change rapidly
The symptom of kind brain decline, thus the symptom of brain decline can be effectively improved.Clinically Nicergoline is with its unique curative effect,
It is widely used.
Nicergoline is degradable under high temperature and super-humid conditions to wet and thermo-responsive.It is carried out in Nicergoline and auxiliary material
In Study on Compatibility, compatibility is poor under conditions of high humidity with different types of disintegrating agent for discovery Nicergoline, this and disintegration
Agent easily moisture absorption is related.Nicergoline is BCS 2 class drugs of classification, belongs to low-solubility high osmosis drug, Nicergoline is being made
Dissolution in agent is to influence the key factor of bioavilability.The nicergoline tablets listed at present, some stability is preferable, but body
Disintegration is poor in outer medium, and vivo biodistribution availability is low;Some disintegrations are good, but stability is poor, impurity rapid development, imitate the phase
Inside it is difficult to qualification.Needing the technical issues of overcoming is, influencing each other between stability of equilibrium and disintegration, and it is full to obtain the two
The preparation required enough.
It attempts to prepare Buddhist nun ergot using Nicergoline, microcrystalline cellulose, calcium monohydrogen phosphate, carmethose and magnesium stearate
Forest tract.Wherein, it is coated for film-coating or sugar-coat.It is that microcrystalline cellulose and carboxylic first are fine to advantageous auxiliary material is disintegrated in label composition
Plain sodium is tieed up, wherein microcrystalline cellulose is that filler has weaker calving disaggregation, and market model is more;Carmethose is parent
Aqueous binder, on the market according to viscosity difference be divided into it is low it is viscous, in glue and high-adhesive.Using above-mentioned composition, for reality
The purpose of existing fater disintegration dissolution, the scheme normally occurred are the microcrystalline celluloses using different model, improve disintegration;Or
The carmethose of different model is replaced, hydrophily is improved.
It is tested, the microcrystalline cellulose such as granule for the various different models that domestic market is commercially available is respectively adopted
The carmethose of the PH101 of diameter, large-sized PH200, highdensity PH301, the KG802 of low-density and different viscosities
Such as low viscous 7LF PH, in 7MF PH, the high viscous 7HF PH that glue, adopted after mixing auxiliary material and main ingredient using conventional method
The nicergoline tablets being prepared with vertical compression technique, or pass through the techniques such as wet granulation, drying, whole grain, sieving, tabletting, preparation
Obtained nicergoline tablets cannot be disintegrated completely, and dissolution is slow.
Summary of the invention
Based on current nicergoline tablets there are the problem of, will the present invention provides a kind of preparation method of nicergoline tablets
Microcrystalline cellulose and carmethose in prescription are pelletized first, by microcrystalline cellulose-carmethose of preparation
Direct tablet compressing after particle is mixed with Nicergoline, calcium monohydrogen phosphate, magnesium stearate again is coated and aluminum-plastic packaged, obtains Nicergoline
Piece.It can be realized quick and complete disintegration using nicergoline tablets prepared by the method provided by the present invention, achieve the purpose that Fast Stripping.
It is demonstrated experimentally that if not using method provided in the present invention, and use Nicergoline, microcrystalline cellulose, carboxylic
Methylcellulose sodium, calcium monohydrogen phosphate, magnesium stearate powder direct tablet compressing technique or after main ingredient, auxiliary material are mixed jointly through wet process system
The nicergoline tablets of grain technique preparation, can not achieve the purpose of fater disintegration, Fast Stripping.
The present invention provides a kind of nicergoline tablets vertical compression technique without traditional disintegrating agent, using technique provided by the invention
The nicergoline tablets disintegration of preparation rapidly, has good stability.
By in prescription microcrystalline cellulose and carmethose by granulation, make to be disintegrated completely, dissolution is slow
Prescription becomes being disintegrated quickly, completely, dissolves out rapid prescription.Method provided by the invention had both been free of traditional disintegrating agent and had guaranteed
The stability of product, and realize the fater disintegration of nicergoline tablets, dissolution.
A kind of preparation method of fater disintegration type nicergoline tablets, key step in the present invention are as follows:
Step 1
Prepare the composite auxiliary material particle with fast disintegration property, specific preparation process is, by prescription microcrystalline cellulose and
Carmethose is pelletized using wet granulation technology, by the microcrystalline cellulose of preparation-carmethose particle drying,

Quality research
The sample prepared using embodiment 1-5 and reference examples 1-4 is detected by the quality standard of formulation, especially compared
The dissolution curve situation of embodiment 1-5 sample and reference examples 1-4 sample in different media.
10 embodiment 1-5 of table and reference examples prepare the testing result of sample
By visible 5 sample of embodiment 1- embodiment prepared using the method provided by the present invention of data in table 10, in pH6.8 medium
Dissolution is apparently higher than the sample of reference examples 1-4 preparation.Disintegration time limited investigates the equal energy of sample for showing prepared by embodiment 1- embodiment 5
Quick and complete disintegration, and reference examples 1 and 2 sample of reference examples are not disintegrated, reference examples 3 and the disintegration of 4 sample of reference examples are incomplete.
Sample prepared by embodiment 1 to embodiment 5 is disintegrated rapidly within 1min in above-mentioned 3 kinds of media, is shown as
Fast Stripping.Reference examples 1 and 2 sample of reference examples in pH1.2 medium and pH4.0 medium, because in prescription calcium monohydrogen phosphate in pH1.2
It gradually dissolves, the slow corrosion of sample, but is not disintegrated in medium and pH4.0 medium, it is partially slow to show dissolution;In pH6.8 medium
Because calcium monohydrogen phosphate is insoluble, reference examples sample is not disintegrated, and can not be dissolved out.Reference examples 3 and as usual 4 samples in above-mentioned 3 kinds of media,
Disintegration is slowly and incomplete, is disintegrated at not continuing to be disintegrated after big, shows as slowly dissolving out, in the same time the amount of dissolution
It is significantly less than embodiment.
