The two journeys: pharmacokinetics and pharmacodynamics
Splits every drug question into two halves — this is the map the rest of the course hangs on.

- ADME: the drug's journey through the body — Pharmacokinetics (what the body does to the drug) is Module 4.
- The synapse: release, binding and termination — Pharmacodynamics (what the drug does to the brain) happens mostly at the synapse.

- Primary effects and side effects — With both journeys in view, you can explain why a drug has side effects.
- ADME: the drug's journey through the body — Opens the whole pharmacokinetics module.

Pharmacology – study of drug action, including pharmacokinetics – how the body affects the drug – and pharmacodynamics – how the drug affects the body (brain). Psychopharmacology – study of how psychoactive drugs affect the brain and behavior – goes beyond just pharmacodynamics.

- Pharmacology
“Pharmacology – study of drug action”Diapositivas 01, p. 3
The umbrella field. It includes pharmacokinetics and pharmacodynamics.
- Pharmacokinetics
“Pharmacokinetics – how the body affects the drug”Diapositivas 01, p. 3
Absorption, distribution, metabolism and elimination (ADME) — the body acting on the drug.
- Pharmacodynamics
“Pharmacodynamics – how the drug affects the body (brain)”Diapositivas 01, p. 3
The drug acting on its targets — receptors, transporters, enzymes.
- Psychopharmacology
“Psychopharmacology – study of how psychoactive drugs affect the brain and *behavior*”Diapositivas 01, p. 3
The emphasis on behavior is the professor's: it goes “beyond just pharmacodynamics”.
