Questions & Step-by-Step Solutions
What does the term 'bioavailability' refer to in pharmacokinetics?
Step 1: Understand that bioavailability is a term used in pharmacokinetics, which is the study of how drugs move through the body.
Step 2: Know that when a drug is taken, it needs to enter the bloodstream to have an effect.
Step 3: Realize that bioavailability measures how much of the drug actually gets into the bloodstream compared to how much was originally taken.
Step 4: Remember that a higher bioavailability means more of the drug is available to work in the body, while a lower bioavailability means less is available.
