Experimental example 2 preparations shaping technical studies
1, the selection of filler
The adjuvant that tablet is commonly used has starch, dextrin, lactose etc., is filler with starch, dextrin, lactose respectively therefore, carries out pressure testing, according to trial test, adopts 85% alcohol granulation, and tabletting serves as to investigate index with compressibility and disintegration time, and the result is as follows.
Table filler kind screening 1
Prescription principal agent (%) starch (%) dextrin (%) lactose (%) compressibility disintegration time hygroscopicity
1 80 20---general, hardness differ from slightly 37 minutes+
2 80-20-general, part sliver 40 minutes+
3 80---20 is general, sliver there are slightly 35 minutes-
4 80 10 10-general, hardness differ from slightly 34 minutes+
5 80-10 10 is general, slightly sliver 36 minutes-
6 80 10-10 is general, slightly sliver 38 minutes-
Annotate: compressibility is investigated:
Good: a wet granulation granule yield is more than 70%, and tablet hardness is good;
Generally: a wet granulation granule yield 50-70%, tablet hardness is poor slightly;
Difference: a wet granulation granule yield is below 50%, loose particles, and tablet hardness is poor.
Average disintegration time: press official method, get 6 meansigma methodss.
Hygroscopicity is investigated: relative humidity is 92.5%, investigates 24h:
+++color is dark, the surface is withered;
++ color is dark, the surface is not withered;
+ color is dark a little, the surface is not withered;
-color outward appearance no change.
According to The above results as can be known, more than the compressibility of three kinds of adjuvants all not ideal, and disintegration time is longer.Because of the low price of starch, so take all factors into consideration, on the basis of prescription 1, increase and use 30 POVIDONE K 30 BP/USP 30, to increase the hardness of tablet, the result is as follows.
The screening 2 of table filler kind
Prescription principal agent (%) starch (%) 30 POVIDONE K 30 BP/USP 30 (%) compressibility disintegration time
7 80 13 7 is not so good, sticking 28 minutes
8 80 15 5 is good, moderate 29 minutes of hardness
9 80 17 3 is good, moderate 32 minutes of hardness
Test shows, select 30 POVIDONE K 30 BP/USP 30 and starch can well improve the indexs such as compressibility, disintegration time of sheet, simultaneously microcrystalline Cellulose, pregelatinized Starch, dextrin, lactose, starch, 30 POVIDONE K 30 BP/USP 30 have been carried out the use that cooperatively interacts, find singly with bigger improvement is all arranged, but be used to good with 30 POVIDONE K 30 BP/USP 30 and starch especially; And 30 POVIDONE K 30 BP/USP 30 reaches 3% of total recipe quantity, can significantly improve the compressibility of sheet, and disintegration time is moderate, and the pressure that makes tablet also can reach the requirement of coating.The amount of polyvidone then has the sticking phenomenon, so take all factors into consideration slightly 7%, definite prescription is: select starch and 30 POVIDONE K 30 BP/USP 30 to be filler, wherein 30 POVIDONE K 30 BP/USP 30 consumptions are 2-6%, preferred 3% of the prescription total amount, starch adds to full dose and gets final product then according to the amount of every batch of medicated powder.
2, lubricant determines
The requirement of particulate flowability during in order to ensure tabletting adds the proper lubrication agent.The general conventional lubricants of tablet is magnesium stearate, micropowder silica gel, Pulvis Talci, through trial test, finding that above-mentioned adjuvant uses separately or is used can both satisfy the preparation requirement, but especially with magnesium stearate for well, so undertaken preferably by the consumption of particulate flowability to magnesium stearate, the result is as follows.
The consumption preference data table of table lubricant
The consumption of sample number magnesium stearate (%) is angle of repose as a result
10 mobility of particles still can 39.3
2 0.3 mobility of particles general 34.2
3 0.5 mobility of particles better 30.3
4 1.0 flowabilities 29.5
According to above-mentioned result of the test, the magnesium stearate consumption can both satisfy the preparation requirement between 0-1.0%, takes all factors into consideration, and the consumption of preferred magnesium stearate is 0.5%.
