Learn pharmacokinetics
The core ideas, one page each
Plain-language explainers for pharmacy and medical students. Every article has a live mini simulator so you can see the idea, not just read it.
- 01Half-life: how long a drug stays in your bodyWhat elimination half-life means, how to calculate it from clearance and volume, and why it decides dosing frequency.Read
- 02Steady state: when levels stop risingWhy repeated doses build up, why steady state takes about five half-lives, and what accumulation ratio means.Read
- 03Area under the curve (AUC): total drug exposureWhat AUC measures, how it relates to dose, bioavailability and clearance, and why vancomycin dosing now targets AUC.Read
- 04Bioavailability: how much of a dose reaches the bloodOral bioavailability (F), first-pass metabolism, and why IV and oral doses of the same drug differ.Read
- 05Loading dose: reaching target levels fasterWhen and why a larger first dose is used, and how to calculate it from volume and target concentration.Read
Practise with real drug presets
Vancomycin, Gentamicin, Paracetamol, Ibuprofen: each preset comes with a short explanation of how the drug moves through the body.
