A pharmaceutical representative is asked by a physician about a use of the drug not covered in the approved labeling. The rep should:

In pharmacology, what does 'half-life' (t½) of a drug mean?
Answer: The time required for the plasma concentration of a drug to reduce by 50%
Half-life is the time required for the concentration of a drug in the bloodstream to decrease by half, which determines dosing intervals.
