Pharmacokinetics
Absorption, distribution, metabolism and elimination (ADME): how route, barriers, liver enzymes and half-life decide how much drug reaches the brain, and for how long.
- Why it matters
- The same molecule can be a medicine or a hazard depending on route and timing. Dosing schedules, interactions and withdrawal all follow from ADME.
- You'll be able to
- Predict how route, enzyme changes and half-life alter a drug's concentration over time — and what that means clinically.
ADME: the drug's journey through the body
The overview map of pharmacokinetics: four processes that decide how much drug reaches the brain, when, and for how long.
