A patient takes two medications.
Drug A is taken once per day; drug B is taken every 8 hours.
Which conclusion about drug A is correct?
Has a wider therapeutic range than drug B.
Has a higher rate of protein binding than drug B.
Has a longer half-life than drug B.
Is less toxic than drug B.
The Correct Answer is C
Choice A rationale:
The frequency of drug administration doesn’t necessarily determine the therapeutic range.
Choice B rationale:
Protein binding is not directly related to the frequency of drug administration.
Choice C rationale:
Drug A has a longer half-life than drug B. This is because drugs with longer half-lives need to be administered less frequently.
