Q. What does the term 'bioavailability' refer to in pharmacokinetics?
A.
The rate of drug elimination
B.
The fraction of an administered dose that reaches systemic circulation
C.
The volume of distribution of a drug
D.
The time taken for a drug to exert its effect
Solution
Bioavailability refers to the proportion of a drug that enters the circulation when introduced into the body and is available for therapeutic effect.
Correct Answer:
B
— The fraction of an administered dose that reaches systemic circulation
