Transporters are involved in clinically significant drug-drug interactions (DDI). Such interactions can occur at multiple sites, including in organs important in drug absorption (e.g. intestine), elimination (e.g. liver and kidneys) and distribution (e.g. brain). Notably, some of these interactions can be “hidden”, occurring in a tissue with no discernible trace in the systemic circulation. In addition, for drugs that are both transported and metabolized, DDI will most prominent when they occur at the “rate-limiting step” in the clearance of the drug. Thus, identifying this step is important for predicting such DDI. To illustrate such interactions, I will focus my presentation on clinically relevant DDI at these sites, involving P-glycoprotein, OATPs, and other transporters. IVIVC of these interactions will also be addressed. P-glycoprotein based DDI at the human blood-brain barrier, measured by PET imaging, will also be discussed. This webinar will help you make decisions about when to be concerned about DDI during the drug development process.
Jashvant (Jash) Unadkat, Ph.D. is a Professor of Pharmaceutics in the School of Pharmacy at the University of Washington, Seattle. He received his Bachelor’s degree in Pharmacy (B.Pharm.) from the University of London (1977), his Ph.D. from the University of Manchester (1982) and his postdoctoral training at the University of California at San Francisco (1982-85). Dr. Unadkat’s research interests are focused on elucidating the mechanisms of transport and metabolism of anti-viral and anti-cancer drugs. In particular his laboratory has been interested in metabolism and transport of drugs during pregnancy, and transport of drugs across the placental, intestinal and blood-brain barrier. Dr. Unadkat heads up a program (UWRAPT, http://sop.washington.edu/uwrapt) funded by a consortium of pharmaceutical companies to quantify the expression of transporters in human tissues. Dr. Unadkat has published more than 140 peer-reviewed research papers. He is a fellow of the AAAS, AAPS, JSSX, and the founding member and the past chair (1999-2001) of the focus group of AAPS on Drug Transport and Uptake. Dr. Unadkat has been an Associate Editor for the Journal of Pharmaceutical Sciences, an Editor of AAPS Journal, and a member of the NIH Pharmacology study section (2000-3). Dr. Unadkat is currently on the editorial board of J. Pharm. Sci and the AAPS Journal. He has organized or co-organized numerous national and international conferences on the role of transporters and pregnancy in disposition of drugs.
