Question

Quizplus · Accepted Answer

Tachyphylaxis refers to the rapid decrease in the response to a drug after repeated doses over a short period of time. It is most likely to occur once sensation has returned to normal levels, indicating a diminished effect of the drug despite its continued administration. This phenomenon is not solely related to the issues of initial anesthesia effectiveness, the understanding of its mechanisms, or the pH of tissues in inflammation contexts as suggested by the other options.
