Quizplus · Accepted Answer

Pharmacokinetic tolerance refers to changes in how the body handles a drug, such as changes in absorption, distribution, metabolism, and elimination, which can lead to lower levels of the drug reaching its site of action and reduced drug effectiveness. Conditioned and behavioral tolerance do not directly affect drug levels, and pharmacodynamic tolerance refers to changes in the responsiveness of the target receptors to the drug, rather than changes in drug levels.
