From the Guidelines
To achieve a Morphine Milligram Equivalent (MME) of 126 with an oxycodone IR/ER combination, you could use a regimen of oxycodone ER 40mg twice daily (total 80mg) plus oxycodone IR 10mg four times daily as needed (potential total 40mg), but a more appropriate calculation based on the conversion factor would be to use oxycodone ER 40mg twice daily (total 80mg) which equals 120mg, and since oxycodone has a conversion factor of 1.5, this would provide a daily MME of 180, exceeding the target, so a revised regimen of oxycodone ER 30mg twice daily (total 60mg) plus oxycodone IR 10mg four times daily as needed (potential total 40mg) would be more suitable, as the 60mg of oxycodone ER would equal 90 MME and the additional 40mg of oxycodone IR would equal 60 MME, totaling 150 MME, still slightly above the target, thus a regimen of oxycodone ER 28mg twice daily (total 56mg) plus oxycodone IR 10mg four times daily as needed (potential total 40mg) would provide a daily MME of 126 (56mg oxycodone ER × 1.5 = 84 MME + 40mg oxycodone IR × 1.5 = 42 MME + 0 MME from the difference between the target and the calculated dose, but to exactly match the target, the dose should be adjusted to 56mg oxycodone ER × 1.5 = 84 MME + 28mg oxycodone IR × 1.5 = 42 MME). The extended-release formulation provides baseline pain control over 12 hours, while the immediate-release tablets address breakthrough pain. This approach balances consistent pain management with flexibility for pain fluctuations, as supported by the study 1. The ER component minimizes peaks and troughs in blood levels, potentially reducing side effects, while the IR component allows for timely response to breakthrough pain. The conversion factor for oxycodone is 1.5, as indicated in the study 1, which means that for every 1mg of oxycodone, it is equivalent to 1.5mg of morphine. This regimen should be initiated only after careful assessment of the patient's pain needs, opioid tolerance, and risk factors, as recommended in the guideline 1. Regular monitoring for efficacy and side effects is essential, with dose adjustments made as needed. Remember that the goal is to use the lowest effective dose to minimize risks while providing adequate pain control, as emphasized in the studies 1.

From the Research
Achieving MME of 126 with Oxycodone IR/ER Combination
To achieve a Morphine Milligram Equivalent (MME) of 126 with an oxycodone IR/ER combination, several factors must be considered, including the patient's individual needs, the severity of their pain, and their medical history.
- The studies provided do not directly address how to achieve an MME of 126 with oxycodone IR/ER combination 2, 3, 4, 5, 6.
- However, it is known that oxycodone is a potent opioid analgesic, and its dosage must be carefully managed to avoid adverse effects 3.
- The combination of oxycodone with other analgesics, such as acetaminophen or pregabalin, may enhance its analgesic effect and reduce the risk of adverse effects 2, 4.
- A study on the safety and tolerability of biphasic immediate-release/extended-release oxycodone/acetaminophen tablets found that the combination was well-tolerated and effective in managing pain 5.
- Another study found that oxycodone/naloxone as add-on therapy to gabapentin or pregabalin was effective and safe in managing chemotherapy-induced peripheral neuropathy 6.
Dosage Considerations
- The dosage of oxycodone IR/ER combination required to achieve an MME of 126 will depend on the individual patient's needs and medical history.
- It is essential to consult the prescribing information and clinical guidelines for oxycodone IR/ER combination to determine the appropriate dosage.
- The patient's response to the medication should be closely monitored, and the dosage adjusted as needed to achieve adequate pain relief while minimizing adverse effects.
Safety and Efficacy
- The safety and efficacy of oxycodone IR/ER combination have been established in several clinical trials 2, 3, 4, 5, 6.
- However, as with any opioid analgesic, there is a risk of adverse effects, including respiratory depression, constipation, and addiction.
- It is crucial to carefully evaluate the benefits and risks of oxycodone IR/ER combination and to monitor patients closely for signs of adverse effects.
