Abstract
The invention relates to the use of cross-linked polyvinylpyrrolidone of an average particle size of from 5 - 60 [mu]m and a hydration capacity of more than 7 g/g as tablet disintegrant.
Description
The present invention relates to particle mean size is that 5~60 μ m and hydration capability are higher than the purposes of the finely dispersed cross-linked polyvinylpyrrolidonefor of 7g/g as tablet disintegrant.
The disintegration rate and the rate of dissolution that use disintegrating agent to improve tablet are generally approved already.
About this point, the most frequently used a kind of disintegrating agent is a crospolyvinylpyrrolidone.Such crospolyvinylpyrrolidone is commercially available, for example from BASF Aktiengesellschaft's
The CL type, or from ISP Investments Inc.'s
The XL type.
Crospolyvinylpyrrolidone mainly with particle mean size greater than the thick form of 100 μ m as tablet disintegrant (Kollidon CL is about 120 μ m, and Polyplasdone XL is about 130 μ m).Although the big disintegrate of granularity is effective, but granularity greatly also has many shortcomings, and tablet surface is more coarse when for example storing under wet condition, resistance to crushing is low, resistance to crushing reduces when storing under wet condition, tablet mixes inhomogeneous and isolating tendency takes place in tablet mixture.Other shortcoming is that thick disintegrating agent granule causes uncomfortable gritty mouthfeel.
At present, generally believe that always the disintegrate effect is relevant with granularity.Therefore, and the disintegrate effect that smaller particles should always can be significantly reduced (referring to V.Buehler, " medicine polyvinylpyrrolidone excipient ", the 128th page reaches each page subsequently, Springer Verlag Berlin Heidelberg, 2005).Therefore, Polyplasdone XL 10 (granularity is about 30 μ m) is on duty mutually with the disintegrate effect of Kollidon CL-M (granularity is about 5 μ m).Therefore, given play to specific disintegrate effect in order to make these granule products, needed much higher concentration, this causes cost, and higher more humidification is quick with tablet, thereby is disadvantageous.Usually, also can not reach fast disintegrate as using the crospolyvinylpyrrolidone coarse granule even improve concentration.
US 6,677, and 417 disclose granularity is the crospolyvinylpyrrolidone of>400 μ m to the 1500 μ m purposes as tablet disintegrant.
The objective of the invention is to seek the tablet disintegrant that helps avoid above-mentioned shortcoming.
Therefore, found the defined purposes of beginning.The particle mean size of the crospolyvinylpyrrolidone disintegrating agent that the present invention is used is 5-60 μ m, preferred 10-50 μ m, especially preferred 15-40 μ m.Hydration capability is higher than 7.0g/g, preferably is higher than 7.5g/g, especially preferably is higher than 8.0g/g, and can be up to 12.0g/g.
Hydration capability is measured by following method:
Take by weighing the 2g polymer to centrifuge tube, and expanded 15 minutes with 40ml is water-soluble.Subsequently, with 2000rpm centrifugal 15 minutes, pour out supernatant, sample is weighed once more.

Such crospolyvinylpyrrolidone is can be by itself known and be called the polymerization preparation of popcorn polymerization.For example precipitation polymerization or polymerisation in bulk are carried out by known method in described popcorn polymerization.Example of known method such as a kind of method described in the EP-B-0 177 812, wherein by under oxygen and the non-existent condition of polymerization initiator, heating 99.6~98.8wt%N-vinyl pyrrolidone and 0.4~1.2wt% begin described popcorn polymerization as the temperature of mixture to 100~150 of the chemical compound with at least two ethylenic unsaturated double-bonds of cross-linking agent ℃.
Comprise at least two ethylenic unsaturated double-bonds in the molecule as the described chemical compound of cross-linking agent.Especially suitable example is alkylidene diacrylamine such as methylene diacrylamine and N; N '-acryloyl group ethylenediamine, N; N '-divinyl ethylidene-urea, N; N '-divinyl propylidene urea, ethylene-3-(N-vinyl pyrrolidone), N; N '-divinyl diimidazole base (2,2 ') butane and 1,1 '-two (3; 3 '-vinyl benzo imidazole radicals-2-ketone)-1, the 4-butane.The example of other suitable crosslinking agent is two (methyl) acrylic acid alkylidene diol ester such as ethylene glycol diacrylate, Ethylene glycol dimethacrylate, acrylic acid tetraethylene glycol (TEG) ester, dimethacrylate tetraethylene glycol (TEG) ester, acrylic acid diethylene glycol ester, methacrylic acid diethylene glycol ester; Aromatic divinyl compound such as divinylbenzene and divinyl toluene; With vinyl acrylate, allyl acrylate, allyl methacrylate, divinyl diox, pentaerythritol triallyl ether, and the mixture of described cross-linking agent.The preferred cross-linking agent that uses is N, N '-divinyl ethylidene-urea.
The consumption of cross-linking agent is 0.1~10wt% based on amount of monomer used in the polymerization, preferred 1~4wt%.
This polymerization can be initiated in the presence of small amounts of sodium hydroxide solution or potassium hydroxide solution.Form polymerisable popcorn polymer at short notice, this polymerisable popcorn polymer is when adding the N-vinyl pyrrolidone in addition and continuing to add cross-linking agent, the popcorn polymerization that does not have induction period is also finished in beginning, wherein according to the present invention even before popcorn polymerization begins by feeding the granularity that inert gas is controlled the gained popcorn polymer in the preferred monomer in being incorporated into aggregation container.But, during induction period in polymerization, begin to feed inert gas at the latest, and make inert gas during whole popcorn polymerization, pass through reactant mixture.
In order to carry out solvent-free popcorn polymerization reaction, i.e. polymerisation in bulk makes the monomer deactivation of introducing by feeding nitrogen, is heated to 100~200 ℃ then, preferred 150~180 ℃ temperature.Advantageously even between polymerization period, all continue to make gentle nitrogen current to pass through monomer.Also realized the eliminating of oxygen by polyblend under monomer boiling and pressure below atmospheric pressure.But, can under reduced pressure feed noble gas simultaneously and carry out popcorn polymerization.Depend on monomeric consumption and selected temperature, mixture polymerization in 1~20 hour.Obtain the popcorn polymer of powder type thus, productive rate is higher than 90%.
Yet for the preparation popcorn polymer, the precipitation polymerization in water is preferred.In this case, select monomeric concentration rightly, make reactant mixture during entire reaction, can both obtain satisfactory stirring.If monomeric concentration is too high in the water, 95wt% for example, then polymer beads becomes and is clamminess, thereby than more difficult stirring in rarer aqueous solution.In order in conventional stirred vessel, to react, select based on for example about 5~30wt% of aqueous mixture, the monomer concentration of preferred 10~20wt%.If use more strong agitator, the monomer concentration of aqueous solution also can be brought up to 50wt%, and suitable words concentration can be higher.Maybe advantageously begin popcorn polymerization with dense relatively solution in some cases, then thin up during reaction.
Preferably carry out popcorn polymerization to avoid any possible monomer hydrolysis being higher than under 6 the pH value.Can be by adding a spot of alkali such as sodium hydroxide or ammonia or adding a spot of commonly used buffer salt such as sodium carbonate, sodium bicarbonate or sodium phosphate are regulated pH value.If suitable, could be by would treating that polymeric mixture heated is to seething with excitement and making inert gas realize the eliminating of oxygen with the granularity of control popcorn polymer by reactant mixture in addition.
In this case, control the granularity of popcorn polymer by the amount of the inert gas by polymeric solution.If provide a spot of noble gas to reactant mixture, then obtain the flower-shaped polymer of unpolished rice usually, and if make a large amount of noble gases by polymeric solution, then obtain thinner popcorn polymer.Based on various restrictive conditions such as container dimensional, temperature and pressure, can not point out to regulate the accurate condition of the concrete granularity of popcorn polymer to each concrete condition.Just can easily find the exact amount that to pass through the noble gas of reactant mixture under the concrete condition by simple test several times.Point out that as top the amount of the noble gas by reactant mixture is 0.01~100, preferred 0.1~30 liter of noble gas/rise reactant mixture/hour.
Can use rare gas such as helium, neon or argon as noble gas.Carbon dioxide also is suitable.The preferred nitrogen that uses.
In order to remove dissolved oxygen fully, also can be with a small amount of, be that Reducing agent such as sodium sulfite, sodium pyrosulfite, sodium dithionate, ascorbic acid or the Reducing agent mixture of 0.1~1wt% joins in the reactant mixture for example based on monomer mixture.In preferred embodiments, popcorn polymerization takes place in the presence of as the sodium dithionate of Reducing agent.
Can in wide region, change polymerization temperature, for example about 20~200 ℃, preferred 50~150 ℃.
In especially preferred precipitation polymerization embodiment, if in inert gas, add hot water soluble comonomer, partial cross-linked dose, water and suitable buffer agent and Reducing agent, up to first polymer beads occurring.If desired, if added the mixture of one or more above-mentioned comonomers and residue cross-linking agent and suitable water as diluent then in 0.2~5 hour, this mixture is the deactivation by being blown into nitrogen in advance.The advantage of this method is that popcorn polymerization only need be used the short time.
Usually about 90% to>99% the productive rate with theoretical yield obtains popcorn polymer.They can be by filtering or centrifugally separating with aqueous suspension, with after washing and dry in conventional drying device such as heated-air circulation oven (circulating air drying oven) or vacuum drying oven, slurry formula exsiccator, revolver drier, fluidized bed dryer or pneumatic conveyer dryer.Not only water insoluble and all solvents of this popcorn polymer, and slight swelling is only arranged therein.Swelling volume in water is 8~10L/kg.
