It is made, Quality advance group 4 is made by the 5th group in the table 4 of embodiment 4.
Experiment 1:The clinical test of pesticide effectiveness
Use the clinical examination that pharmaceutical composition of the present invention carries out polycentric random, double blinding, placebo parallel control is studied
Test, patient's sum is 120 people, be randomly divided into 3 groups, the age, inclusion criteria was the slight anxious patients to moderate from 24 to 65 years old
And meet with disease of digestive system, mucosal lesion or easy bleeding, more than 50 years old age wherein at least one condition.In research
Period patient is prohibited from using other sedatives, anti-inflammatory agent, muscle relaxant, depressor, antipsychotic drug, antidepressants or antianxiety
Medicine.Each group takes placebo, original quality group and (contains the citrate of 0.62% chemical compounds I, the Chinese holly of 0.46% compound ii respectively
Same regimen acid salt, the citrate of 0.25% compound III), Quality advance group 3 citrate of 0.05% chemical compounds I (contain).Medication
After 30 days, curative effect (antianxiety curative effect carries out evaluation analysis according to Hamilton anxiety scale) and adverse reaction evaluation are carried out.Its
In, the effective percentage of placebo is 10%, and adverse reaction rate is 5%;The effective percentage of original quality group is 65%, bad anti-
It is 35% to answer incidence;The effective percentage of Quality advance group 3 is 75%, and adverse reaction rate is 15%.
Clinical observation result shows, original quality group and Quality advance group are respectively provided with obvious curative effect, and Quality advance group
Rate of adverse reactions be significantly lower than original quality group, illustrate Quality advance group not only with anxiolytic effect, it is not
Good reaction also has obvious reduction.
Experiment 2:Hepatotoxicity wind agitation is tested
The serious adverse reaction of tandospirone citrate composition, which is used for a long time, includes the damage to liver, below by small
The long term administration of mouse tests to investigate degree of impairment of the tandospirone citrate composition to liver of different quality group.
120 18~22g of body weight male ICR mouse is randomly divided into 6 groups, every group 20, each administration group is as shown in table 5
Medicine and dosage continuous gavage be administered 28 days, blank group physiological saline gavage, takes fasting 12h before blood, the 29th by 1 times/day
It takes two parts of blood by eyeball rear vein beard, and transaminase AST and concentration of ALT in serum are determined respectively.
Test data mean+SDRepresent, data analysis is carried out with SPSS softwares.Compare between group
Using one-way analysis of variance (One-Way ANOVA), with P<0.05 and P<0.01 is with significant difference.
The influence of table 5, long term administration to liver function
Compared with blank control group:#P<0.05,##P<0.01;Compared with original quality group:*P<0.05, * * P<0.01.
Result of the test shows, is administered alone daily using routine dose, and original quality group is compared with blank group, mice serum
Middle AST and concentration of ALT significantly raise (##P<0.01);And use the tandospirone citrate composition after Quality advance to give daily
Medicine, compared with original quality group, AST and concentration of ALT rising condition are significantly reduced in mice serum, especially Quality advance group
2、3、4(**P<0.01);And AST and ALT concentration is with citrate, the compound ii of chemical compounds I in Quality advance group
Citrate and compound III citrate content reduction and reduce, show use quality improve after the smooth degree of citric acid
Spiral shell one compositions significantly reduce its toxicity to liver, and drug safety is higher.
Experiment 3:Antidepression animal model experiment
(1) Tail suspension test (antidepression experiment)
84 mouse are randomly divided into 7 groups, every group 12, gastric infusion is grouped once by the medicine in table 6.Each group mouse
1h after administration, will paste hang upside down at the tail point 1cm of mouse, make it be in hang state, head by the feet on hook with immobilization with adhesive tape
Apart from experimental bench about 15cm, operation one every time records the desperate row of mouse in 6min using animal behavior video analytic system
For the accumulative dead time (s) after analysis in 4min.Judge that motionless standard stops struggling for mouse, it is static in the state of hanging by the feet
It is motionless.
Test data mean+SDRepresent, data analysis is carried out with SPSS softwares.Compare between group
Using one-way analysis of variance (One-Way ANOVA), with P<0.05 and P<0.01 is with significant difference.
Table 6, Tail suspension test result
Compared with blank control group:#P<0.05,##P<0.01;Compared with original quality group:*P<0.05,**P<0.01.
Test result indicates that, compared with blank control group, accumulative dead time of positive drug group mouse significantly reduce (##P<
0.01);The mouse accumulative dead time of original quality group and Quality advance group 1,2,3,4 is both less than blank control group, illustrates original
Beginning quality group has certain antidepressant effect with Quality advance group;Compared with original quality group, the mouse of Quality advance group 2,3,4
The accumulative dead time significantly reduce (* * P<0.01), show that Quality advance group antidepressant effect is better than original quality group;By matter
Measure raising group 3 and 4 results are understood, the mouse accumulative dead time is reduced with the increase of the citrate content of chemical compounds I,
Less than Quality advance group 1 and 2, show in the range of the application, the antidepressant effect of tandospirone citrate composition is with chemical combination
The increase of the citrate content of thing I and improve.
(2) mouse forced swimming test (antidepression experiment)
84 mouse are randomly divided into 7 groups, every group 12, medicine is grouped gastric infusion once according to the form below.Each group mouse
1h after administration, mouse is respectively put into high 20cm, diameter 10cm lucite cylinder, contained in lucite cylinder into 25 ± 1 DEG C
Water, height 15cm, operation one every time, and use the swimming row of mouse in animal behavior video analytic system record 6min
For, after analysis in 4min mouse forced swimming test accumulative dead time (s).Dead time is judged as that animal stops earning in water
Prick, in floating state, only tiny limb motion is to keep head to float on the surface.
Test data mean+SDRepresent, data analysis is carried out with SPSS softwares.Compare between group
Using one-way analysis of variance (One-Way ANOVA), with P<0.05 and P<0.01 is with significant difference.
Table 7, mouse forced swimming test result
Compared with blank control group:#P<0.05,##P<0.01;Compared with original quality group:*P<0.05,**P<0.01.
Test result indicates that, compared with blank control group, accumulative dead time of positive drug group mouse significantly reduce (##P<
0.01);The mouse accumulative dead time of original quality group and Quality advance group 1,2,3,4 is both less than blank control group, illustrates original
Beginning quality group has certain antidepressant effect with Quality advance group;Compared with original quality group, the mouse of Quality advance group 2,3,4
The accumulative dead time significantly reduce (* * P<0.01);From the result of Quality advance group 3 and 4, mouse add up the dead time with
The reduction of the citrate content of chemical compounds I and increase, and less than Quality advance group 1, show in the range of the application, citron
The antidepressant effect of sour Tandospirone composition improves with the increase of the citrate content of chemical compounds I.
The studies above result shows, by the control of each index components, in the framework of the present definition, can effectively carry
