Abstract
A slow-releasing tablet of orally taken medicine is composed of a blank layer consisting of slow-releasing material, adhesive and lubricant, and a slow-releasing layer prepared from water-soluble medicine, slow releasing material, adhesive and lubricant. Its advantage is durable and stable blood concentration.
Description
One, technical field
The present invention relates to a kind of slow-releasing tablets of oral medicine and preparation method thereof
Two, background technology
Some medicines of Shi Yonging owing to the character of some medicine itself, are made conventional tablet and are taken clinically, can be very fast by metabolism in human body.In order to reach effective therapeutic effect, must increase the number of times of taking of this type of medicine.Will cause the shortcoming that medicining times is many, blood concentration fluctuation is big, side reaction is big like this.In order to improve curative effect of medication, reduce medicining times, guarantee drug safety, these medicines must be made slow releasing tablet.Slow releasing tablet is made the slow releasing tablet of homogeneous usually by the even back of principal agent, slow-release material, binding agent and mix lubricant tabletting.This slow releasing tablet often can not play good slow release effect for the good principal agent of water solublity.
Three, summary of the invention
The present invention provides a kind of double-layered slow releasing tablet at above technical deficiency just.
Technical scheme of the present invention is as follows:
A kind of slow-releasing tablets of oral medicine, it is made of with the slow release layer that contains principal agent is superimposed the blanket layer that does not contain principal agent, wherein, the blanket layer that does not contain principal agent mainly is made up of slow-release material, binding agent and lubricant, the slow release layer that contains principal agent mainly is made up of highly-water-soluble oral medicine, slow-release material, binding agent and lubricant, blanket layer is that 0.32-2.1 is than 1 with the mass ratio of slow release layer, in slow release layer, the principal agent quality accounts for the ratio of slow release layer quality can decide according to the dosage size of principal agent needs, can select for use between 1%-75%.
Specifically, slow-releasing tablets of oral medicine of the present invention, shown in an embodiment of the present invention, by per 1000 tablet qualities: slow-release material is the 50-300 gram in the blanket layer, and binding agent is the 10-50 gram, lubricant is the 1-3 gram; Contain that the highly-water-soluble oral medicine is the 1.5-500 gram in the slow release layer of principal agent, slow-release material is the 80-200 gram, and binding agent is the 5-10 gram, and lubricant is the 0.86-7.1 gram.
Above-mentioned highly-water-soluble oral medicine can be ditropan XL, metformin hydrochloride, Yin Da Paan.
Above-mentioned slow-release material can be Rikemal B 200, hydroxypropyl emthylcellulose (HPMC), ethyl cellulose, or the mixture of their two or more slow-release material.
Above-mentioned binding agent can be sodium carboxymethyl cellulose, polyvinylpyrrolidone K30 (PVP-K30), polyvinylpyrrolidone K90 (PVP-K90), or the mixture of their two or more binding agent.
Above-mentioned lubricant can be magnesium stearate, micropowder silica gel, Pulvis Talci.
Slow-releasing tablets of oral medicine of the present invention can adopt wet method tabletting method for making.
A kind of method for making of slow-releasing tablets of oral medicine of the present invention, it comprises the steps:
1. blanket layer: get slow-release material, binding agent by the charge ratio of blanket layer, by equivalent incremental method mix homogeneously, cross 60 mesh sieves, 1. mixing must mix powder;
2. slow release layer: get highly-water-soluble oral medicine, slow-release material, binding agent by the charge ratio of slow release layer, by equivalent incremental method mix homogeneously, cross 60 mesh sieves, 2. mixing must mix powder;
The preparation of step 3. soft material and wet granular: get mixed powder that step 2 makes 1., mix powder 2., add 20% Diluted Alcohol solution respectively, mediate the system soft material, cross 20 mesh sieves, make wet grain 1. and wet grain 2.;
2. 1. the wet grain that step 3 is made placed respectively 50-60 ℃ of oven drying 3-4 hour with wet grain, after crossing 18 mesh sieve granulate, must do granule, add lubricant after weighing respectively, mixing, the wet grain that will be after the drying adds lubricant 1. and wet grain 2. place two hoppers of bi-layer tablet press respectively, compacting promptly gets slow-releasing tablets of oral medicine of the present invention in flakes on bi-layer tablet press.
Slow-releasing tablets of oral medicine of the present invention can adopt the compressing dry granulation method for making.
A kind of method for making of slow-releasing tablets of oral medicine of the present invention, it comprises the steps:
1. blanket layer: get slow-release material, binding agent by the charge ratio of blanket layer, by equivalent incremental method mix homogeneously, cross 60 mesh sieves, 1. mixing must mix powder;
2. slow release layer: get highly-water-soluble oral medicine, slow-release material, binding agent by the charge ratio of slow release layer, by equivalent incremental method mix homogeneously, cross 60 mesh sieves, 2. mixing must mix powder;
Characteristics of the present invention:
1, from pharmaceutical dosage form, general slow releasing preparation mostly adopts the effect that pharmaceutical pack the method in the insoluble macromolecular scaffold of being hidden in is reached slow release.The mechanism that discharges is because thereby the retardation of the slow releasing agent of macromolecular scaffold delays the release of medicine.But, only simply contain and to reach ideal slow release effect for the big medicine of water solublity.For instance:, principal agent and sustained-release matrix are not only reached the good slow release effect by 1: 1 mixed also can cause the heavy overweight problem of sheet if drug content is big; Otherwise even drug content is not high, the ratio of slow releasing agent and principal agent can not play the good slow release effect greater than 10 sometimes.The present invention adopts double-layered slow releasing tablet technology, is hidden in pharmaceutical pack on the basis of high molecular slow-release agent, has increased the not blanket layer of pastille of one deck again, reduced the release area of medicine, reduced the speed of drug release, guaranteed the slow releasing function of medicine, its mechanism is seen accompanying drawing 1.
2, from the angle of absorption of human body, general slow releasing preparation is principal agent and sustained-release matrix uniform mixing, after taking, principal agent in human body from sustained-release matrix to around stripping, reach slow release effect.For the very big medicine of water solublity, increase slow-release material again after sustained-release matrix is increased to a certain degree and can not strengthen slow releasing function.And the present invention has increased the blank slow release layer of one deck, has strengthened the retardation for drug release, can reach ideal slow release effect.
3, will take slow-releasing tablets of oral medicine of the present invention and do contrast (seeing accompanying drawing 2-4) with blood drug level-time graph of taking behind the common slow-releasing tablets of oral medicine, it is long to take the time that the blood drug level of slow-releasing tablets of oral medicine of the present invention keeps as can be seen, and concentration is more steady.
