The issue of herb-drug interactions has been widely reported. Herbal ingredients can activate nuclear receptors and further induce the gene expression alteration of drug-metabolizing enzyme and/or transporter. Therefore, the herb-drug interaction will happen when the herbs and drugs are coadministered. This kind of interaction is called inductive herb-drug interactions. Pregnane X Receptor (PXR...

Background: There has been a drastic increase in herb-drug interactions day-by-day as a result of an increase in the population using herb and its supplements along with the contemporary medicines. Objectives: To discuss the safety of usage of herbal medicines along with contemporary medicines in the management of lifestyle disorders. Method: This is a systemic review with narrative analysis. A...

The worldwide using of herb products and the increasing potential herb-drug interaction issue has raised enthusiasm on discovering the underlying mechanisms. Previous review indicated that the interactions may be mediated by metabolism enzymes and transporters in pharmacokinetic pathways. On the other hand, an increasing number of studies found that genetic variations showed some influence on h...

Purpose Individuals using herbal medicines concomitantly with prescription drugs are at risk of harms due to herb-drug interactions. As part of a prospective active surveillance study to identify natural health product harms, a tool to identify herb-drug interactions was created for clinician use. Such tools require regular updating to remain clinically relevant. Our objective was to review the...

Quantitative prediction of herb-drug interaction risk remains challenging. A quantitative framework to assess a potential interaction was used to evaluate a mechanism not previously tested in humans. The semipurified milk thistle product, silibinin, was selected as an exemplar herbal product inhibitor of raloxifene intestinal glucuronidation. Physiologically based pharmacokinetic (PBPK) model s...

Supported by a usage history that predates written records and the perception that “natural” ensures safety, herbal products have increasingly been incorporated into Western health care. Consumers often self-administer these products concomitantly with conventional medications without informing their health care provider(s). Such herb–drug combinations can produce untoward effects when the herb...
