Objective:
To explore the toxic effect on mouse administrated Kudiezi injection multy times a day, and on rats repeat administrated for many days.
Method:
Mouse tail intravenous injection of Kudiezi, 0.04 mL x g(-1), 3 times a day, rats tail intravenous injection of Kudiezi, 20, 10, 4 mL x kg(-1), once a day, for 6 weeks.
Result:
There is no abnormal to the mouses administrated many times a day. The rats administrated large doses of drug for many days have certain effects on hematology, blood biochemistry. Some animals appear liver, kidney lesions mild, injection local appear haemorrhage, edema and inflammatory reaction.
Conclusion:
The mouse which was intravenous injection in the dose of 180 times Kudiezi injection as much as people used, revealed no toxicity reaction. Repeated large-dose administration, rats caused by lesions of the main target organs may be for kidney, liver. But the recovery result on liver, kidney toxicity was reversible, no delayed toxicity. At the same time, large doses of long-term administration of local have a certain irritation. Tips the medication should be under the guidance of doctors, and pay attention to replace the injection site. This research will provide safety basis for the clinical use of Kudiezi injection.
Insights
Kudiezi injection showed no toxicity in mice, but repeated high doses in rats caused reversible liver and kidney damage. Local irritation occurred with long-term, high-dose use, advising medical guidance and site rotation for clinical safety.
Area of Science:
- Pharmacology
- Toxicology
- Traditional Chinese Medicine
Context:
- Kudiezi injection is a traditional Chinese medicine formulation.
- Understanding its toxicological profile is crucial for safe clinical application.
Purpose:
- To evaluate the toxic effects of Kudiezi injection in mice and rats.
- To establish a safety basis for the clinical use of Kudiezi injection.
Summary:
- Mice receiving frequent Kudiezi injections showed no adverse effects.
- Rats administered high doses of Kudiezi injection for extended periods exhibited reversible hematological, biochemical, and histopathological changes, primarily affecting the liver and kidneys.
- Local irritation, including hemorrhage, edema, and inflammation, was observed at injection sites.
Impact:
- This study provides essential safety data for the clinical application of Kudiezi injection.
- Findings suggest that while generally safe in mice, high-dose, long-term administration in rats warrants caution due to potential organ toxicity and local irritation.
- Recommendations include medical supervision and rotation of injection sites to mitigate risks.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
