Questions and Answers

What is fluctuation in pharmacology?

The average plasma concentration of a drug over a dosing interval.

The amount of drug that is excreted unchanged in the urine

The ratio of the maximum plasma concentration to the trough plasma concentration of a drug. (correct)

The time it takes for a drug to reach steady state

What does a high fluctuation value indicate?

The ratio of the steady-state peak or maximum concentration to the trough or minimum concentration is small.

The ratio of the steady-state peak or maximum concentration to the trough or minimum concentration is large (correct)

The drug has a short half-life

The drug is highly bound to plasma proteins.

Why is it preferable to have a smaller ratio of maximum to minimum concentration at steady state?

A smaller ratio indicates that the drug has a more predictable pharmacokinetic profile (correct)

A smaller ratio indicates that the drug has a longer half-life

A smaller ratio indicates that the drug is more effective

A smaller ratio indicates that the drug is less toxic
