Created from Youtube video: https://www.youtube.com/watch?v=PGzT3cTPah8videoConcepts covered:pharmacodynamics, receptor proteins, agonists, antagonists, potency and efficacy
The video explains pharmacodynamics, focusing on how drugs interact with receptor proteins to elicit physiological responses. It distinguishes between agonists, which mimic native ligands, and antagonists, which block receptor activity, and discusses concepts like potency and efficacy in drug action.

Pharmacodynamics: Mechanisms of Drug Action
Concepts covered:pharmacodynamics, receptor proteins, agonists, antagonists, potency and efficacy
The video explains pharmacodynamics, focusing on how drugs interact with receptor proteins to elicit physiological responses. It distinguishes between agonists, which mimic native ligands, and antagonists, which block receptor activity, and discusses concepts like potency and efficacy in drug action.
Question 1
Pharmacodynamics studies how drugs affect the body.
Question 2
How does an antagonist affect a receptor?
Question 3
The study of how a drug affects the body is called _____.
Question 4
CASE STUDY: A new drug is being tested for its effects on heart rate. It is known to bind to a specific receptor in the heart muscle cells, mimicking the action of the natural ligand.
All are effects of agonists except?
Question 5
Potency and efficacy are the same in pharmacology.
Question 6
What does pharmacodynamics study in drug action?
Question 7
Potency is related to a drug's _____ for a particular receptor.
Question 8
CASE STUDY: A pharmaceutical company is developing a drug to lower blood pressure. The drug acts as an antagonist to a receptor involved in vasoconstriction.
All are antagonist effects except?
Question 9
Agonists mimic native ligands to activate receptors.
Question 10
What determines a drug's potency?
Question 11
A drug that mimics the native ligand is known as an _____.
