Question

Which therapeutic index value would be the drug of choice?

A) 20
B) 10
C) 1
D) 0.1
E) Any value would be equally effective.

Answer 1

The drug of choice would be the one with the highest therapeutic index value.

Step-by-step explanation:

The therapeutic index (TI) is a measure of the safety and effectiveness of a drug. It is calculated by dividing the median lethal dose (LD50) by the median effective dose (ED50). The higher the therapeutic index, the safer the drug is considered to be. Therefore, in this case, the drug of choice would be the one with the highest therapeutic index value. Out of the given options, the drug with a therapeutic index value of 20 (option A) would be the preferred choice.
