Basics of Drug Interactions EXPLAINED | Inhibition & Induction

The video tutorial by Kevin Tokoph covers xenobiotic drug metabolism, focusing on the liver's role and the cytochrome P-450 enzyme. It explains drug interactions through competitive and irreversible inhibition, where drugs compete for enzyme sites or permanently inactivate enzymes. The tutorial also discusses induction, where a drug increases enzyme production, affecting the metabolism of other drugs. These mechanisms impact drug efficacy and patient outcomes, such as heart rate changes.

Describe the process of induction in drug metabolism.

What is the role of the pregnane X receptor (PXR) in drug metabolism?

How does drug A induce the production of cytochrome P-450 enzymes?

What are the potential effects on heart rate when drug A is administered with drug B?
