What are Agonists? Or do you know, What are antagonists? From a pharmacological perspective, can we compare them to heroes and villains that exist inside our bodies? Let us explore their whole dynamic in this pharmacology video. We will go over the differences and compare Agonist vs Antagonist.

▬ 📃 What are Agonists and Antagonists? ▬▬▬▬▬▬▬▬▬▬
Agonists are chemicals or drugs that bind and activate Drug Receptors and produce a response. Whereas Antagonists are drugs or chemicals that bind with receptors but do not activate them.

Antagonists reduce the probability of the agonist combining with the receptor, and so, reduce or block its action. Which is why they are also called “blockers”.

▬ 📜 Pharmacology Important Terms ▬▬▬▬▬▬▬▬▬▬
In the very beginning of the video, we introduce you to the different terms of pharmacology, used in the video. These are:
🟠 Drug affinity
🟠 Intrinsic Activity
🟠 Dose-Response Curve
🟠 Drug Potency
🟠 Receptor Reserve

▬ 📃 Agonist vs Antagonist ▬▬▬▬▬▬▬▬▬▬
Let us explore the differences between agonists and antagonists. Watch the video, as we delve deep into the agonist vs antagonist pharmacology and the drug-receptor interactions.

▬ 📜 Agonist Pharmacology
Let us list down the types of agonists, that are explained in the video, below:
🟡 Full Agonist
🟡 Partial Agonist
🟡 Inverse Agonist

▬ 📃 Antagonists Pharmacology ▬▬▬▬▬▬▬▬▬▬
Types of Drug Antagonists can be classified into multiple types, like:
🔵 Competitive Antagonist
🔵 Irreversible Antagonist
🔵 Allosteric Antagonist
🔵 Non-Competitive Antagonist
🔵 Functional Antagonist (Physiological Antagonist)
🔵 Chemical Antagonist

That’s just an overview of what you are going to learn in the video. To learn them in detail, enjoy the story of our hero and the villain in the video!
