Embodiment 6 freeze-dried powder injection of pantoprazole sodium cause the experimental study of rat diarrhoea incidence rate
40 of healthy SD rats, male, body weight (180 ± 20) g is divided into normal control group (10), test A group (15), test B group (15) at random.Wherein:
Test A group: joined the freeze-dried powder injection of pantoprazole sodium of doing above-mentioned comparative example's 1 preparation of intravenous drip in 0.9% sodium chloride injection in continuous 7 days, dosage is 10mg Pantoprazole Sodium/(kgd);
Test B group: continuous 7 join the freeze-dried powder injection of pantoprazole sodium of doing 1 preparation of the intravenous drip embodiment of the invention in 0.9% sodium chloride injection, and dosage is 10mg Pantoprazole Sodium/(kgd);
Normal control group: continuous 2 days intravenous drip normal saline 100ml/ (kgd).
Administration places metabolic cage with rat after finishing, and spreads white filter paper at the bottom of the cage to observe the stool situation, and every day, observed and recorded was 2 times.Its diarrhoea methods of marking is:
0 minute: stool was normal;
1 minute: laxativeness, stool is visible slight wet soft;
2 minutes: moderate diarrhoea, stool were wet and shapeless, and have slight crissum painted;
3 minutes: severe diarrhoea, watery stool was also painted with the severe crissum.
(3) result of the test and analysis
Behind the rat injection freeze-dried powder injection of pantoprazole sodium, can be observed the diarrhoea untoward reaction, the diarrheal appraisal result sees that table 2 is following.
Table 2 is respectively organized rat diarrhoea situation relatively
Compare with test A group,
*P＜0.05,
*P＜0.01.
Result of the test according to table 2 can be found out; Freeze-dried powder injection of pantoprazole sodium diarrhoea incidence rate of the present invention is starkly lower than 1 group of comparative example (P＜0.05 or P＜0.01), and this is indicating that its medication interdependence and therapeutic effect to the patient all has positive facilitation.
