Interactions between clopidogrel and traditional Chinese medicine

Area of Science:

• Pharmacology
• Integrative Medicine
• Herbal Medicine

Background:

• Traditional Chinese Medicine (TCM) is increasingly used globally.
• Clopidogrel is vital for preventing atherothrombotic events.
• Patients on clopidogrel may concurrently use TCM, raising interaction concerns.

Purpose of the Study:

• To investigate potential pharmacokinetic and pharmacodynamic interactions between clopidogrel and TCM.
• To assess how TCM affects clopidogrel efficacy and bleeding risk.

Main Methods:

• A comprehensive literature search was conducted.
• Databases used included Web of Science, PubMed, and the Cochrane Library.
• Analysis focused on pharmacokinetic and pharmacodynamic data of clopidogrel and TCM interactions.

Main Results:

• Several TCM herbs alter clopidogrel pharmacokinetics (AUC, Cmax) and its active metabolite levels.
• Some TCMs enhance clopidogrel's antiplatelet activity, while others decrease it.
• Certain TCMs, like Danggui, may increase bleeding risk when combined with clopidogrel.

Conclusions:

• TCM can significantly influence clopidogrel's efficacy and safety profile.
• Awareness of these drug-herb interactions is essential for clinicians.
• Further research may enable synergistic therapeutic outcomes by combining clopidogrel with specific TCMs.
