Time enhances passive drug delivery. All of the following statements are true except which one?
A)Augmented passive drug delivery continues following termination of the applied current.
B)Iontophoretic applicators should remain in place to maximize the amount of drug delivered transcutaneously.
C)Longer treatment times will afford potentially greater drug delivery.
D)Higher intensities during the treatment time with iontophoresis will negate the need for passive drug delivery.

Question

Quizplus · Accepted Answer

Higher intensities during iontophoresis primarily enhance active transport mechanisms rather than passive diffusion. Passive drug delivery is not negated by higher intensities but is a separate mechanism that can complement active transport methods like iontophoresis.
