These in vitro models can help to identify herbal ingredients with the potential to alter the safety or efficacy of prescription drugs
WESTBURY, NY - Jun 6, 2018 - BioIVT, a leading provider of biospecimens and related services, today announced that it will be hosting a webinar entitled Whole-cell In Vitro Models Can Predict Clinically-relevant Herb-Drug Interactions (HDIs) at 11 am ET on June 20.
As herb-based dietary supplements continue to grow in popularity, consumers and healthcare professionals have questions related to the potential for herb-drug interactions (HDIs) that could occur in patients taking them together with medications, said Amy Roe, PhD, DABT, senior toxicologist at The Procter & Gamble Company, and the webinars presenter. But that information is difficult to determine because these products are often complex herbal mixtures with multiple ingredients.
It is difficult to identify HDIs because it is not always feasible to routinely conduct clinical trials and applying a deconstructionist approach to a complex mixture, using conventional in vitro methods, is less predictive of in vivo effects, said Jonathan Jackson, PhD senior scientist, ADME-Tox at BioIVT. We demonstrated that our model (TRANSPORTER CERTIFIED hepatocytes in sandwich culture) and approach were well suited to quantitatively assessing HDI potential providing an in vivo prediction that was remarkably in agreement with clinical observations.
During the webinar, Dr. Roe will discuss how she collaborated with Dr. Jackson and the BioIVT team and employed this novel in vitro method to investigate clinically-relevant HDIs with Schisandra species.
Clinical studies had shown that Schisandra sphenanthera extract (SSE) reduced midazolam (MDZ) clearance in humans. In their study, Drs. Roe and Jackson showed that BioIVTs in vitro human hepatic model accurately predicted the SSE-MDZ interaction observed in the clinic. This research has been published in Drug Metabolism and Disposition.1
Dr. Roe will also describe how sandwich-cultured human hepatocytes can be used to evaluate other herbal extracts, complex mixtures, and toxicity endpoints.
