Lesson 979 of 1524
Drug Administration
bioavailability: the drug concentration available to bind to receptors at its target tissue or site of action; a subcategory of absorption
Practice this chapterbioavailability — the drug concentration available to bind to receptors at its target tissue or site of action; a subcategory of absorption. pharmacodynamics — the way a drug interacts with receptors, target cells, body systems, and organs to produce effects, or what the drug does to the body. therapeutic index — the ratio of the dose of a drug that produces a therapeutic effect to the dose that causes toxicity; sometimes known as the therapeutic window. pharmacokinetics — the movement of a drug through the body, or what the body does to the drug.
Worked example
What does “bioavailability” mean in Drug Administration?
- 1Use the wording this chapter gives for bioavailability.
- 2The book says: the drug concentration available to bind to receptors at its target tissue or site of action; a subcategory of absorption.
- 3Do not use the meaning of pharmacodynamics. That term means the way a drug interacts with receptors, target cells, body systems, and organs to produce effects, or what the drug does to the body.
Result: the drug concentration available to bind to receptors at its target tissue or site of action; a subcategory of absorption
Why. That is the meaning this chapter gives for bioavailability.
Do not swap bioavailability and pharmacodynamics. bioavailability means the drug concentration available to bind to receptors at its target tissue or site of action; a subcategory of absorption. pharmacodynamics means the way a drug interacts with receptors, target cells, body systems, and organs to produce effects, or what the drug does to the body.
