Pharmacokinetics

What this unit covers

The resources follow the four steps of ADME: absorption, distribution, metabolism and excretion. The mind map Pharmacokinetics sets out the basic definitions, from transfer out of the site of administration to irreversible removal from the body. Other maps and flashcards go deeper into single topics, such as first-pass metabolism, cytochrome P450 enzymes, protein binding and brain penetration.

Where to start

Begin with the quiz Pharmacology Exam 1, which opens with the basic question of what a drug does to the body, or 1807NRS Safe Administration of Medications 1, which asks what pharmacokinetics includes and how drugs are absorbed in the gut. Then read the mind map Pharmacokinetics to see how the four steps connect.

1. Take a short quiz and note what you miss.
2. Open the matching mind map, such as Drug Metabolism/Excretion or Basic Principles II.
3. Work through a flashcard deck on the same topic.
4. Return to the quiz and see what has changed.

Routes and delivery

Several resources look at how a drug gets into the body. The mind map ROUTES: PARENTERAL explains that parenteral means any route other than oral, sublingual, buccal or rectal. The quizzes Drug Delivery and Drug Interactions test examples, such as how diazepam may be given, and how food and drugs can interact through the CYP system.

Using quizzes and maps together

Quizzes show what you can recall. Maps show how the ideas link. Use a quiz first to find a weak spot, then read the map for that topic. Teachers can set a quiz as a starter or share a map as a recap. Numbers-based topics, such as clearance, volume of distribution and half-life, have their own quizzes and flashcards.
