[Three-day-type transdermal fentanyl patch conversion by rapid titration method with short-acting oral oxycodone for cancer pain].

This study compared the efficacy and safety of a 3-day-type transdermal fentanyl patch conversion by the rapid titration method to short-acting oral oxycodone for cancer pain.We evaluated seven hospitalized cancer patients who had moderate to severe cancer pain.Pain intensity was rated using an 11-point(0-10)numerical rating scale(NRS).All 7 patients initially reported their pain intensity at rest as NRS≥4 during treatment by Non-Steroidal Anti-Inflammatory Drugs(NSAIDs).Short - acting oral oxycodone(OxiNorm®)5 mg was administered to all patients.One hour after short-acting oral oxycodone was administered, pain assessment was carried out using NRS by the author.Short -acting oral oxycodone was administered four times a day periodically, and as a rescue dose.If the total daily dose of short-acting oral oxycodone was stable for 2 days, we switched to the 3-day-type transdermal fentanyl patch.The optimal dosage of the 3-day-type transdermal fentanyl patch was determined by titration of short-acting oral oxycodone.All 7 patients reported mild levels(NRS≤2)of cancer pain for 2 days.No serious side effects were reported.The 3-day-type transdermal fentanyl patch conversion by the rapid titration method with short-acting oral oxycodone can be accomplished safely and effectively for patients with moderate cancer pain.
