Drug Herb Interactions

With Dr. Greg Sperber

We can predict potential drug-herb interactions. This course takes the basic pharmacology principles discussed in the Basics of Pharmacology course, including the ADME scheme and the therapeutic index, and applies them to understanding and predicting drug-herb interactions. In addition, recent areas of research related to interactions, such as p-glycoprotein and other transporters, will be discussed. The emphasis is on both the theoretical prediction and real world application of strategies for preventing and dealing with interactions. This includes a discussion about creating a Drug-Herb Interaction Matrix for determining an individual patient's risk. The template for the matrix will be provided as part of the course.

This online course is based on my book published by Blue Poppy: Integrative Pharmacology, Combining modern pharmacology and Chinese medicine written with Bob Flaws. It is the second in series of courses leading to a certificate in Drug-Herb Interaction Expert.

Course Goals

1. Understand how the basics of pharmacokinetics, including the ADME scheme, and pharmacodynamics can be used to predict drug-herb interactions
2. Identify the risks involved with combining drugs and herbs
3. Create a Drug-Herb Interaction Matrix for assessing individual patient risk and as a tool for communication
