Pharmacokinetics (ADME) Explained | Absorption, Distribution, Metabolism & Excretion | Pharmacology

Master Pharmacokinetics (ADME) in one complete college-level lecture! This video breaks down everything you need to know about how the body handles a drug — from the moment you swallow a pill to the moment it leaves your system.

📚 WHAT YOU'LL LEARN IN THIS VIDEO:
✅ What pharmacokinetics is and how it differs from pharmacodynamics
✅ The 4 phases of ADME — Absorption, Distribution, Metabolism & Excretion
✅ Routes of administration and bioavailability explained
✅ First-pass effect and why it matters clinically
✅ Volume of distribution, Cmax, Tmax, and Area Under the Curve (AUC)
✅ Plasma protein binding and the Free Drug Hypothesis
✅ Blood-Brain Barrier and tissue distribution barriers
✅ Cytochrome P450 enzyme system (CYP3A4, CYP2D6, CYP2C9 & more)
✅ Phase I vs Phase II biotransformation reactions
✅ Pharmacogenomics — poor vs ultra-rapid metabolizers
✅ Drug-drug interactions: enzyme inducers and inhibitors
✅ Renal excretion — filtration, secretion, and reabsorption
✅ Clearance, half-life, steady state, and loading dose equations
✅ Zero-order vs first-order elimination kinetics
✅ Clinical applications: renal impairment, liver disease, and elderly patients

🎓 WHO IS THIS FOR?
This lecture is designed for pharmacy students, medical students, nursing students, pre-med undergraduates, and anyone studying pharmacology at the college or professional level. Perfect for USMLE Step 1, NAPLEX, NCLEX, and pharmacology course exams.
