Question

In plasma drug concentration versus time graph as shown in the picture, what should be the correct option for the marked place?

(a) Maximum safe concentration

(b) Minimum effective concentration

(c) Therapeutic range

(d) Onset of action

This question was addressed to me during an interview for a job.

I need to ask this question from Pharmacokinetic topic in portion Pharmacokinetic Drug Interactions & Basic Considerations of Drug Biotechnology

Answer 1

The correct choice is (c) Therapeutic range

The best I can explain: The therapeutic range is between the minimum effective concentration and maximum safe concentration. This is the concentration where the drug continues to give therapeutic effect. Above this level, it will be toxic to the patient. And below this it won’t give a therapeutic effect.
