Mechanism of Drug-drug Interaction Between Salvianolate Injection and Aspirin
October 9, 2017 updated by: Xiyuan Hospital of China Academy of Chinese Medical Sciences
Research on Mechanism of Drug-drug Interaction Between Salvianolate Injection and Aspirin Based on the Metabolic Enzyme and PK-PD Model
The combination of anti-platelet medicine treatment and Chinese traditional medicine (TCM) promoting blood circulation to removing blood stasis is widely used in treatment for cardiovascular disease.
However, the material foundation, effective mechanism and drug-drug interaction is still not clear.
In order to solve the puzzle of rational use of Joint application by TCM and Western Medicine(WM),investigators conduct a research on mechanism of drug-drug interaction between salvianolate injection and aspirin based on metabolic enzyme and PK-PD model.
This clinical trial contain three groups, aspirin group, salvianolate injection group and combination (salvianolate injection+aspirin) group.
Investigators collect blood samples at special time points during post-administration.Investigators have already find out the Salvianolate's pharmacokinetic characteristics in vivo and establish the biological sample-testing analysis method in previous research.
Depending on these results, this clinical trial aim to explore the pharmacodynamics-pharmacokinetics(PK-PD) characteristics of combination with Salvianolate and aspirin through biomarkers, blood concentration.
Finally clarify the TCM and WM material basis and mutual mechanism of drug interaction and guide reasonable clinical prescription.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: aspirin arm
only take aspirin (100mg,qd) orally for 10 days treatment course
|
Anti-platelet medicine treatment and Chinese traditional medicine (TCM) promoting blood circulation to removing blood stasis is widely used in treatment for cardiovascular disease.
|
Active Comparator: salvianolate injection arm
only inject salvianolate(200mg+5%Glucose Injection 250ml,iv) for 10 days treatment course
|
The main ingredient of salvianolate injection is salvianolic acid B(SAB) which is extracted from the root of red salvia.
Red salvia is used in traditional Chinese Medicine.
It could promote blood circulation to removing blood stasis,which is clinically effective in treatment for cardiovascular disease.

Experimental: aspirin and salvianolate injection arm
take aspirin (100mg,qd) orally and inject salvianolate(200mg+5%Glucose Injection 250ml,iv) for 10 days treatment course
