We may not be able to predict all drug-herb interactions, but we can determine potentials for interactions. This seminar examines how to approach these potential drug-herb interactions. A discussion of basic pharmacology, including the ADME scheme (absorption, distribution, metabolism, and elimination), the therapeutic index, and p-glycoprotein form the foundation of this understanding. The participant will leave with real skills to assess potential interactions and the ability to determine which are important, which aren’t, and which may be in the future. In addition, we will discuss the nine drugs and ten herbs to be most concerned about, and why they are a concern. This course has been completely updated and is based on current research.
