Description
Technical field
The invention belongs to drug coating to make formula and technology field, and in particular to a kind of stomach dissolution type film coating is pre-
Mixture and preparation method thereof.
Background technology
In China, the application of film-coated technique is in the process of accelerated development, and the market prospects of film coating are very wide
Wealthy, the perfect raising innovation of coating material and packaging technique is also imperative.It is to lean on film bag to have increasing pharmaceutical preparation
Clothing come cover its abnormal taste, cover it is various not by the colors liked of masses.Want to have reached using film-coated technique
Mainly there is both direction during complete hiding label this mesh of color.First, increase coating weight gain;Second, the coating using high covering power
Product.Pharmacy corporation then more favor high covering power coated product come reach cover label purpose.Because wrapped relative to increase
Clothing increase weight, using high covering power coated product on Coating times it is shorter, coated product usage amount is less, cost of drugs is lower.
As film-coating product research and development side, its main technological means is exactly to be reached by increasing the ratio of covering effect in product
To this purpose, these compositions are largely made up of the insoluble raw material such as titanium dioxide, talcum powder.More particulate matter meetings
Settling rate is accelerated after causing to be configured to coating solution, to bringing very big influence in coating process and on coating effect.
Speed and the particle diameter settled according to sedimentation theory (Stokes theory) it is square directly proportional, be situated between with continuous phase
The viscosity of matter is inversely proportional.Because when film coating pre-mix dose is developed, insoluble titanium dioxide, talcum powder are all in composition
Supplier will also be passed through using process in addition in process of production Task-size Controlling to very small material and the work such as grind
Sequence, so the method that uses was addition thickener to improve dielectric viscosity in research coating solution free settling problem in the past.But cross
What high coating fluid viscosity was brought therewith is that coating process atomization is not thorough, blocks up rifle;A series of problems, such as unilateral coarse after coating.
The content of the invention
Only the rate of settling is reduced by increase liquid viscosity to solve above-mentioned high cover film coating easily cause that coating is not smooth, wraps
The unilateral technical problem such as coarse after clothing, the invention provides a kind of stomach dissolution type film-coating premixing for including colloid MCC stabilizers
Agent and preparation method thereof.
The invention provides a kind of stomach dissolved film coating pre-mix dose, the pre-mixing agent includes the component of following mass parts:Into
Membrane material 30-50 parts, antiplastering aid 10-20 parts, colouring agent 0.5-5 parts, covering agent 20-30 parts, plasticizer 5-15 parts, colloid MCC
1-3 parts;
Wherein, colloid MCC includes microcrystalline cellulose and sodium carboxymethylcellulose, microcrystalline cellulose and sodium carboxymethylcellulose
Mass ratio be 1-1.5:8.5-9.
Preferably, filmogen includes the component of following mass parts:HPMC 1-5 parts, polyvinyl alcohol 1-3
Part, copolyvidone 1-2 parts.
Preferably, antiplastering aid is any one in talcum powder, magnesium stearate, stearic acid.
Preferably, covering agent is titanium dioxide.
Preferably, plasticizer is Macrogol 6000, Liquid Macrogol, polyethylene glycol 400, propyl alcohol, glycerine, triacetic acid
Any one in glyceride, dicarboxylic acid dimethyl ester, triacetyl glycerine.
A kind of method for preparing stomach dissolved film coating pre-mix dose of the present invention, this method comprise the following steps:
(1) filmogen 30-50 parts, antiplastering aid 10-20 parts, plasticizer 5-15 parts, colloid MCC1-3 parts are taken, with purified water
6-12 parts, ethanol 2-4 parts uniformly mix 0.8-1h, 35-45 DEG C of dry 4-5h;
(2) colouring agent 0.5-5 parts, opacifier 20-30 parts are added in the dried mixture of upper step, mixes 0.5-1h
Afterwards, it is transferred on grinder and grinds 4-5h, crosses 50 mesh sieves, you can obtain pre-mixing agent.
Beneficial effects of the present invention:Colloid MCC in pre-mixing agent of the present invention improves the stability of coating solution, reduces coating
Liquid precipitate speed effect is better than by addition thickener to alleviate the coating solution rate of settling, and coating process is more smooth, coating
Faster, unilateral effect is finer and smoother after coating for speed.Colloid MCC includes microcrystalline cellulose and sodium carboxymethylcellulose, and colloid MCC is
Dispersant and protecting colloid are played a part of with main body, sodium carboxymethylcellulose with microcrystalline cellulose.
Embodiment
The present invention is carried out with reference to embodiment explanation is explained in detail.
A kind of new auxiliary material colloid MCC has been introduced to increase the stability of liquid, while again not in present invention premix agent prescription
The unilateral effect after coating solution viscosity in use and coating can be influenceed.Colloid MCC is scattered in liquid phase, will not be in continuous phase
It is middle to produce larger viscosity B coefficent, but play the role of hydrogen bond in solution stand, Weak Gels can be formed in continuous phase solution
Space three-dimensional network structure.This network structure makes continuous solution increase its yield value, so that molecule equably divides
It is dispersed in continuous phase, will not sinks.This structure can disappear or be destroyed again when being shaken or being shaken, and viscosity drops rapidly
It is low, and recover the good mobility of its liquid.Colloid MCC is incorporated among the film-coated technique of the present invention, in high shear
It can be uniformly dispersed under power (whipping process) effect, using its above-mentioned characteristic, ultimately form the colloidal solution of uniformity, strengthen liquid
The yield value of phase, the sedimentation of insoluble particulate is prevented, this stable mechanism is different from original single increase viscosity, and it is stable
Mechanism is network struture system, rather than high viscosity systems.
The determination process of formula:
1st, the present invention is carried out based on original high soverlay technique, so using colloid MCC stabilizers direct generation first
For thickener of the prior art.Do not find there is incompatibility with other components in formula among whole ratio examination process
Phenomenon occurs.
2nd, optimum proportioning examination
Based on different covering agent ratios in formula, different amounts of colloid MCC stabilizers are added from the rate of settling, Bao Zao
Unilateral effect is coated to observe, try after process and coating, collects analysis of experimental data table, determines optimum proportioning.
Table 1 adds influences of the different amounts of colloid MCC to coating process
Analysis and summary:Increase with the ratio of insoluble covering agent particulate in film coating pre-mix dose, it is necessary to which colloid MCC is steady
It is also different to determine agent adding proportion, by taking tested recipe as an example, it is 50% to add covering agent maximum ratio wherein, when colloid MCC is steady
It is most preferable to determine effect when agent is added to 3%.Excessive addition colloid MCC stabilizers can cause liquid to tend to gel, it is necessary to more
Big shearing force could destroy hydrogen bond structure, be unfavorable for bag and make.So colloid MCC stabilizers are used in film-coating premixing of the present invention
Optimal proportion in agent prescription is 1-3%.
