What is the purpose of opioid rotation in chronic pain management?

• A. To improve analgesia and reduce side effects, tolerance, and hyperalgesia
• B. To increase dose to achieve same effect
• C. To confuse patient
• D. To decrease analgesia

Answer: (A)

Opioid rotation is used when the current opioid no longer provides optimal relief or causes troublesome side effects. Different opioids differ in receptor activity, metabolism, and active metabolites, so tolerance to one does not perfectly transfer to another. By switching to a different opioid, you can regain better pain control at a similar overall dose and often reduce adverse effects, tolerance, and opioid-induced hyperalgesia. The switch is followed by careful dosing using equianalgesic estimates and close monitoring, with titration as needed rather than simply increasing the dose. This approach is about optimizing relief and function while minimizing harm, not about confusing the patient or decreasing analgesia.
