2O).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.
During referring to produce, " percentage by weight " of the present invention take gram or kilogram as unit adjuvant is carried out proportioning by weight.In view of the needs of Chinese medicinal tablet production and application, its application in Chinese medicinal tablet technique preparation 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, characteristics that quality is high, easy to use.Concrete research process is as follows:
Because medicine disintegrate, maximum leading factor are speed and the water absorption of adjuvant suction, the adjuvant prescription that absorption speed is faster, water absorption is larger, its disintegration must be stronger, 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 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 altogether the experiment of 7 assembly material, 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 take water absorption 2.5 to 3.5 as short, draw, the short prescription scope that collapses
MCC?10%~35% PVPP?10%~20% LHPC?2%~10%
(MCC+PVPP+LHPC=100%)
And MCC: PVPP: LHPC ≈ 6: 3: 1 o'clock, water absorption is 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 |
Draw MCC from the result: PVPP: LHPC (6: 3: 1) prescription water absorption is maximum, and it is all relatively poor that MCC and LHPC use separately water absorption.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 large, 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 as a result disintegrate is effect improved very obvious.
For the checking inorganic salt can improve the water extracted immersing paste dispersible tablet moisture processed 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 at single punch tablet machine respectively, 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 upper table analysis as can be known, add calcium sulfate salt obviously than the salt adding rate of water absorption is not fast; And the short prescription two that collapses:
MCC∶PVPP∶LHPC∶GaSO4=6∶3∶1∶0.6
Be conducive to the dispersible tablet disintegrate processed of the water extracted immersing paste material.
