Drug Receptor Interaction in Pharmacodynamics: Affinity, Agonist & Antagonist Explained

Pharmacodynamics Series – Part 3 (Drug Receptor Relationship) In this short pharmacology video, we explain the drug–receptor relationship in a simple, logical way. You’ll see how drugs bind to receptors, what affinity (KD) means, and the difference between agonists and antagonists. What you’ll learn in this pharmacodynamics lesson: • Types of drug–receptor binding: ionic, hydrogen, van der Waals, covalent • Affinity and KD (dissociation constant): how “sticky” a drug is to its receptor • Agonists: full agonist, partial agonist, inverse agonist • Antagonists: competitive vs non‑competitive antagonist • Allosteric modulators: positive (PAM) and negative (NAM) modulators Use this as a quick review for pharmacology exams, receptor pharmacology questions, and understanding how drug–receptor interactions create a response. ⏱ Timestamps / Chapters: 0:00 – Introduction: what is the drug–receptor relationship? 0:35 – Types of drug–receptor binding (ionic, hydrogen, van der Waals, covalent) 1:45 – Affinity and KD (dissociation constant) explained simply 2:04 – Agonists: full agonist, partial agonist, inverse agonist 3:24 – Antagonists: competitive vs non‑competitive antagonist 4:17 – Allosteric modulators: PAMs and NAMs 5:20 – Summary and key exam takeaways drug receptor relationship, drug receptor interaction, pharmacodynamics, receptor pharmacology, affinity KD, dissociation constant, full agonist, partial agonist, inverse agonist, competitive antagonist, non competitive antagonist, allosteric modulator, PAM NAM, pharmacology, medical pharmacology, pharmacology lecture, pharmacology for medical students, pharmacology for pharmacy students, exam review, USMLE pharmacology, nursing pharmacology #pharmacology #pharmacodynamics #drugreceptor #agonist #antagonist #affinity #KD #medicalstudent #pharmacystudent #nursingstudent --- Welcome to Pharmacology Lore, your secret alchemical laboratory for mastering pharmacology.
