Experimental example 1, the test of preparation prescription craft screening
1, preparation prescription mesostroma kind is selected test
Select the different substrates kind to test take medicine deployment conditions, dripping complexity and made drop pill appearance character in substrate as index, result of the test is as follows.
Substrate is respectively Macrogol 4000 (PEG4000), polyethylene glycol 6000 (PEG6000), PEG4000+PEG6000, and medicine and substrate composition are 1:5, and 75~85 ℃ of dripping temperature, the temperature of condensing agent remain on 10~25 ℃.
Table 1 matrix species is selected result of the test
According to above-mentioned result of the test: with PEG4000 as substrate, medicine difficulties in dispersion, and the smooth rounding property of made drop pill is poor; With PEG6000 and PEG4000+PEG6000(3:2) as substrate, the equal thickness of medicinal liquid after disperseing is difficult for dripping; Use PEG4000+PEG6000(3:1) as substrate, the medicinal liquid stickiness is suitable after disperseing, and a small amount of caking is arranged, and made drop pill is than rounding.Therefore we tentatively select PEG4000+PEG6000(3:1) as the substrate of this product, in order further to increase the dispersion of medicine in substrate, in prescription, add the solubilizing agent PLURONICS F87 and proceed test.
2, solubilizing agent consumption screening test in the preparation prescription
According to above result of the test, in prescription, add solubilizing agent, to increase the dispersion of medicine in substrate, simultaneously screening test is carried out in the consumption of solubilizing agent in the prescription, disperse complexity and made drop pill appearance character as index in substrate take medicine, result of the test is as follows.
Matrix species is selected PEG4000+PEG6000(3:1), PLURONICS F87 is selected in solubilizing agent, and 75~85 ℃ of dripping temperature, the temperature of condensed fluid remain on 10~25 ℃.
Table 2 substrate and solubilizing agent consumption screening test result
According to above result of the test, in prescription, behind the adding solubilizing agent PLURONICS F87, can obviously improve the dispersion of medicine in substrate, the smooth rounding rate of made drop pill is desirable.Therefore we determine that the consumption of solubilizing agent in this preparation prescription is: the amount ranges of medicine and solubilizing agent is 1:(0.36-0.48), preferred agents and solubilizing agent amount ratio are 1:0.42.
3, preparation prescription mesostroma consumption is selected test
Select test and solubilizing agent consumption to select test by matrix species, we determine the preferred PEG4000+PEG6000(3:1 of preparation prescription mesostroma), the preferred PLURONICS F87 of solubilizing agent, and medicine and solubilizing agent amount ratio are 1:10, we do further definite by test to the consumption of prescription mesostroma.This test is selected as index take appearance character, the dissolve scattered time limit of made drop pill, and result of the test is as follows.
This test Chinese medicine and PLURONICS F87 amount ratio are 1:0.42, and 75~85 ℃ of dripping temperature, the temperature of condensing agent remain on 10~25 ℃.
Table 3 preparation prescription mesostroma consumption is selected test
According to above result of the test, the amount ratio of medicine and substrate is 1:(4.5-5.5) time, the dissolve scattered time limit of made drop pill is all qualified, and smooth rounding rate is all more than 90%, therefore we determine that the amount ratio of prescription Chinese medicine and substrate is 1:(4.5-5.5), preferred agents is 1:5 with the substrates quantity ratio.
4, condensed fluid is selected test in the preparation process
Condensed fluid is the important auxiliary agent of drop pill, its density and viscosity directly affect the sedimentation velocity of medicinal liquid and the roundness of drop pill, we are with the decrease speed of made drop pill in condensed fluid and the appearance character index of drop pill, condensed fluid liquid paraffin and dimethicone are carried out screening test, and the result is as follows.
Condensed fluid selection result in table 4 preparation process
Select liquid paraffin, dimethicone 100 to mix as condensed fluid according to above result of the test, the roundness of sedimentation velocity and drop pill is good, make as condensed fluid therefore select liquid paraffin and dimethicone 100 to mix, and both volume parts is than being 3:1.
5, the selection of condensate temperature in the preparation process thereof
In the preparation process of drop pill, the temperature of dripping temperature and condensed fluid is on the impact that forms of drop pill, we are defined as 75~85 ℃ with the dripping temperature, and the phenomenon of observing in the dripping process is selected the temperature of condensing agent by test as index, and the result is as follows.
Dripping temperature and condensate temperature are selected test in table 5 preparation process thereof

6, the selection of water dropper bore test in the preparation process thereof
Take the drop pill character and the ball method of double differences is different as index the drop pill bore is selected, the result is as follows.
The water dropper bore is selected result of the test in table 6 preparation process thereof
When being (internal diameter) 2mm according to above result of the test water dropper bore, the smooth rounding of made drop pill, and the ball method of double differences different be 6.2%, within the limit of pharmacopeia regulation.
To sum up, through the test of preparation prescription craft screening, determine this drop pill prescription mesostroma preferred mass than 3:1 Macrogol 4000 and polyethylene glycol 6000 mixed-matrix, its consumption is preferred, and medicine and PEG4000 and PEG 6000 mixed-matrix weight ratios are 1:5; The preferred PLURONICS F87 of solubilizing agent, its consumption is preferred, and medicine and PLURONICS F87 mass ratio are 1:0.42.
In the technological parameter, preferred 75~85 ℃ of dripping temperature; The preferred liquid of condensed fluid is that Volume fraction is 3:1 paraffin body and dimethicone 100 mixed liquors, preferred 10~25 ℃ of the chilling temperature of condensing agent; Preferred (internal diameter) 2mm of water dropper bore carries out dripping.
