Explain pharmacology basics with a simple example

The short version: pharmacology basics refers to how drugs act on the body and how the body handles drugs. A quick example makes it concrete — First-pass metabolism reduces the bioavailability of many oral drugs.

How to approach it step by step

Once one example makes sense, the method generalises: separate pharmacodynamics from pharmacokinetics, then follow absorption to elimination. In a visual interactive session the example is built on screen piece by piece, so you see which quantity changes at each step instead of only reading a final answer. Ask for a harder variant and the explanation adapts on the spot.

Worked example

First-pass metabolism reduces the bioavailability of many oral drugs.

The mistake most learners make

Assuming a higher dose always gives a proportionally larger effect.
