The curve indicates the drug's margin of safety.
What does a drug's margin of safety indicate?
The difference between the therapeutic and adverse effects of the drug.
What is the therapeutic index of a drug?
The ratio of the dose that produces desired effects to the dose that produces toxic effects in 50 percent of the animals.
Which of the following best describes the compensatory mechanisms discussed in the text?
They decrease the effectiveness of drug binding with receptors
What is the difference between tolerance and sensitization?
Tolerance occurs when larger doses of a drug are needed to achieve the same effect, while sensitization occurs when smaller doses of a drug are needed to achieve a larger effect

What is the difference between tolerance and sensitization?
Tolerance is a decrease in the effectiveness of a drug that is administered repeatedly, while sensitization is an increase in the effectiveness of a drug that is administered repeatedly.
