( facebook medschool. Opioid rotation is closely linked to – but distinct from – the pharmacological concept of equianalgesia. given that opioid drugs differ in their analgesic potency, changing from one to another will generally require re evaluation of the dose if, for the patient’s comfort, equipotency is to be achieved.

Equianalgesic Chart Pdf Patients receiving intravenous oxycodone required approximately 30% more opioid to produce the same alleviation of pain as with intravenous morphine. this gives an inferred iv morphine to iv oxycodone equianalgesic dose ratio of 0.7:1. wide ranges were noted, particularly during oral administration of the opioids. The term equianalgesia, meaning “approximately equal analgesia,” refers to the doses of various opioid analgesics that are estimated to provide the same amount of pain relief. equianalgesic dose calculations are a means for selecting the appropriate initial dosing when changing from one opioid agent or route of administration to another. Table 1. guideline for opioid rotation. step 1. calculate the equianalgesic dose of the new opioid based on the equianalgesic table. if switching to any opioid other than methadone or fentanyl, identify an “automatic dose reduction window” of 25% to 50% lower than the calculated equianalgesic dose. . Step 2: equianalgesic dose of new opioid should be calculated based on a standard equianalgesic dosing table and reduced by 25–50% (table 71.1) patient characteristics should be used to determine degree of reduction (i.e. elderly or frail patients should have dose reductions closer to 50%) if switching to methadone, doses should be reduced by.
