A ratio of the dose of the drug that is toxic to humans versus the minimum effective dose for that pathogen is assessed to predict the potential for toxic drug reactions.This is called the

Quizplus · Accepted Answer

The ratio described in the question is called therapeutic index (TI). It is calculated by dividing the toxic dose of a drug by its minimum effective dose against a pathogen. TI is used to assess the safety of drugs by determining how much higher the therapeutic dose is compared to the toxic dose. A higher TI indicates that the drug is safer, whereas a lower TI suggests that the drug is more likely to cause toxic reactions. Therefore, the best choice is E, therapeutic index.
