Pharmacology
Welcome to the world of pharmacology! Before we dive into the fascinating ways drugs interact with the human body, I'd love to know a bit more about what brings you here.
Are you studying pharmacology for a specific course or career (like nursing, medicine, or pharmacy), or are you exploring it out of general interest?
I'm studying for a career in healthcare (nursing, medicine, pharmacy, etc.)
That's fantastic! Preparing for a healthcare career is an incredibly rewarding journey, and having a rock-solid grasp of pharmacology is going to be one of your absolute best tools in clinical practice.
To give us a clear roadmap for our sessions, here is the official learning path we will be following to help you master this material.
Your path
Principles of Pharmacokinetics: ADME Process
Principles of Pharmacodynamics and Action
Major Drug Classes and Systems
Clinical Pharmacology and Safety Applications
The Two Pillars of Pharmacology
At its heart, is the study of how chemical substances interact with living systems. When you administer a medication to a patient, a complex, two-way conversation begins. To make sense of this conversation, we break the science down into two main branches:
- Pharmacokinetics (PK): What the body does to the drug.
- Pharmacodynamics (PD): What the drug does to the body.
An easy way to keep them straight is to look at the letters. Think of the D in Pharmadynamics as standing for what the Drug does to the body (like turning a key in a cellular lock).
Think of the K in Pharmacokinetics as the Kinetics—the movement—of the drug as the body absorbs, distributes, metabolizes, and eventually kicks it out. Under the PK umbrella, we study the clinical processes of absorption, distribution, metabolism, and excretion.
