An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]
There are no clinical guidelines outlining the use and implementation of opioid rotation. However, this strategy is commonly used for these various situations: pain not controlled by current opioid, pain controlled but in the presence of intolerable adverse events, pain not controlled despite rapid increase in opioid dose, switching to utilize different alternative routes of administration, or ...
