Calcium sulfate: white powder.Density 2.964g/cm
31450 ℃ of fusing points.Easily the moisture absorption is water insoluble, is dissolved in acid.Usually use with two water things and half water thing form.Two water things are commonly called as Gypsum Fibrosum and Gypsum Fibrosum, are the monoclinic system white powders, are dissolved in acid, ammonium salt, glycerol, are slightly soluble in water, are insoluble to ethanol.Density 2.32g/cm
31350～1375 ℃ of fusing points.128 ℃ lose 1.5 molecular waters, are heated to 163 ℃ and lose 2 molecular waters.Half water thing is a white powder, has water absorption, mixes with water to form the slurry that plasticity is easily watered block, promptly solidify every certain hour, and with the volumetric expansion and the heat release of trace.Half water thing has two kinds on α type and β type again.The α type is commonly called as high-strength building gypsum, and the β type is commonly called as Gypsum Fibrosum preparata and bassanite.
Calcium carbonate: be the main component of Calx rock (abbreviation limestone), its molecular formula is CaCO
3, relative molecular mass is 100.09.Wherein calcium oxide accounts for 56.03%, and carbon dioxide accounts for 43.97%.Calcium carbonate mainly contains three kinds of precipitated calcium carbonates, ground calcium carbonate, calcium carbonate activated.
Magnesium sulfate: be a kind of magniferous chemical compound, molecular formula is MgSO
4(or MgSO
47H
2O).The crystal or the white powder of colourless or white easy-weathering.Odorless.Bitter saline taste is arranged.Density 1.68.Lose six molecular crystalline water at 150 ℃, lose whole water of crystallization at 200 ℃.The density 2.66 of anhydride, 1124 ℃ of fusing points decompose simultaneously.Water-soluble, glycerol and ethanol.
Be that unit carries out proportioning by weight with adjuvant with gram or kilogram during " percentage by weight " of the present invention refers to produce.In view of the needs that Chinese medicinal tablet production is used, its application in the Chinese medicinal tablet prepared add, add in can being or in add (can add briefly introduce in add, add).
Chinese medicinal tablet can be on the basis of above-mentioned prescription reasonable pharmaceutic adjuvants such as absorb fillers, excipient correctives, fluidizer, to satisfy drug manufacture and use.
The present invention obtains shortly collapses premixing auxiliary material and has that the method preparation is simple, good stability, quality height, characteristics easy to use.Concrete research process is as follows:
Because medicine disintegrate, maximum leading factor are the speed and the water absorption of adjuvant suction, the adjuvant prescription that absorption speed is fast more, water absorption is big more, its disintegration must be strong more, based on this principle, this experimental design following experiment be to seek the optimum prescription that promotes disintegrate.
Get adjuvant total amount 100g, MCC, PVPP, LHPC three mix by following mixture experiment design experimental group prescription, adding certain adhesive granulates, after the drying, add micropowder silica gel 1g, magnesium stearate 1g mixing, the sheet of tablet heavily is the 1.0g/ sheet in accordance with regulations on single punch tablet machine, and the Hardness Control of tablet is measured the tablet water absorption at (3.5 ± 0.5) kg.cm-2 tabletting.(annotate PVPP except that specializing, all use ISP PVPP-XL)
Mixture experiment design:
Table 1 factor level table (actual value)
If MCC+PVPP+L-HPC=1
With above factor level, through the design of SAS statistical software, select MCC*PVPP*L-HPC exchange interaction saturation experiments group, provide the experiment of 7 assembly material altogether, by tabletting behind the batching experimental formula, detect water absorption.
Table 2 experimental program and table as a result
Date processing and interpretation of result
Draw regression equation, section prediction collection of illustrative plates and equal pitch contour optimization through the analysis of SAS software statistics, collapse condition for short, draw, the short prescription scope that collapses with water absorption 2.5 to 3.5
MCC?10％～35％????PVPP?10％～20％????LHPC?2％～10％
(MCC+PVPP+LHPC＝100％)
And MCC: PVPP: LHPC ≈ 6: 3: 1 o'clock, the water absorption maximum is 3.50ml
Confirmatory experiment:
With above prescription, repeated authentication three times, and with the independent tabletting of MCC, PVPP, LHPC three relatively, the result is as follows:
Table 3 confirmatory experiment table (n=3)
| Prescription | Water absorption (ml) |
| ??MCC∶PVPP∶LHPC6∶3∶1 | ??3.45 |
| ??PVPP | ??3.14 |
| ??MCC | ??1.5 |
| ??LHPC | ??2.2 |
The result draws MCC from checking: PVPP: LHPC (6: 3: 1) prescription water absorption maximum, it is all relatively poor that MCC and LHPC use water absorption separately.Therefore, MCC: PVPP: LHPC (6: 3: 1) disintegrate effect is preferably the highest as disintegrate prescription cost performance.
In infantile heat-clearing and antitussive dispersing tablets, antiviral dispersant tablet and the research of WUJI BAIFENG WAN dispersible tablet formulation and technology; we find; three prescription application urge to collapse prescription one, and still disintegrate is slow; possible reason is; this three prescription is the water extracted immersing paste, and viscosity is big, meets water and forms protecting film; water is difficult for infiltrating the sheet heart, causes the disintegrate difficulty.For this reason, we have added 3% inorganic salt in prescription, and disintegrate as a result is effect improved very obvious.
For the checking inorganic salt can improve the water extracted immersing paste system dispersible tablet moisture permeating speed, this problem has been carried out following experiment:
Prescription one: infantile heat-clearing and antitussive medicated powder 40g, microcrystalline Cellulose 33g, crospolyvinylpyrrolidone 18g, low-substituted hydroxypropyl cellulose sodium 6g, micropowder silica gel 1g, magnesium stearate 1g,
Prescription two: infantile heat-clearing and antitussive medicated powder 40g, microcrystalline Cellulose 32g, crospolyvinylpyrrolidone 17g, low-substituted hydroxypropyl cellulose sodium 5g, micropowder silica gel 1g, magnesium stearate 1g, calcium sulfate 3g
Be pressed into 0.8 specification tablet respectively on single punch tablet machine, the Hardness Control of tablet is at (3.5 ± 0.5) kg.cm-2 tabletting.The same method detects absorbtivity, and the result is as follows:
Table 4 prescription one and prescription two absorption speed tables
From last table analysis as can be known, add calcium sulfate salt obviously than not fast with the salt rate of water absorption; And the short prescription two that collapses:
MCC∶PVPP∶LHPC∶GaSO4＝6∶3∶1∶0.6
Help the disintegrate of the water extracted immersing paste material system dispersible tablet.
