Tolerance for any drug that a person has never taken describes

Question

Quizplus · Accepted Answer

Cross tolerance refers to the phenomenon where tolerance to one drug can sometimes lead to a reduced response to another drug that acts through a similar mechanism. Therefore, tolerance to a drug that a person has never taken before would only be possible through cross tolerance with a related drug. Option A (agonist effects) refers to the effects of a drug that binds to and activates a specific receptor. Option C (antagonist effects) refers to drugs that block or dampen the effects of a specific receptor. Option D (partial agonist effect) refers to drugs that partially activate a receptor and produce less than the maximal response. None of these options suggest tolerance to a drug that a person has never taken before.
