Question

Quizplus · Accepted Answer

Cross-tolerance refers to the phenomenon where a person who has developed tolerance to a specific drug will also develop a tolerance to other drugs in the same class. This is because the drugs in the same class have similar pharmacological actions and affect the same neurotransmitters or receptors in the brain. As a result, the body adapts to the repeated exposure of the drug and develops a tolerance, which makes the person less responsive to the drug's effects. Therefore, the best choice is D - cross-tolerance.
