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.
Choice D rationale:
The toxicity of a drug is not determined by the frequency of its administration.

Correct Answer is D
Explanation
Choice A rationale:
Protein binding does not inactivate the drug. Instead, it can affect the drug’s distribution and bioavailability.
Choice B rationale:
Protein binding does not directly increase the risk of an allergic reaction. Allergic reactions are typically immune responses to a drug, not a result of protein binding.
Choice C rationale:
An idiosyncratic reaction is an unusual or unexpected reaction to a drug, which is not related to protein binding.
Choice D rationale:
Protein binding can lead to the accumulation of the drug. Drugs often cannot cross membranes mainly due to the high molecular mass of the drug-protein complex, resulting in the accumulation of the active compounds.
