AbstractTwo studies including a total of 70 patients evaluated the efficacy and side effects of a combination of initial patient-controlled analgesia (PCA) for dose finding with transdermal fentanyl administration. Patients, requiring strong opioids for severe cancer pain, received intravenous (i.v.) fentanyl on an on-demand basis over a 24 h period. The amount of fentanyl administered was then used for selecting a suitable transdermal therapeutic system (TTS), which remained in place for 72 h. The size of the second TTS was adjusted according to the amount of supplementary i.v. fentanyl required on day 3. Beginning on day 4, oral or subcutaneous morphine was made available as a rescue medication. The use of TTS fentanyl in combination with initial dose titration using PCA resulted in rapid and statistically significant pain relief in both studies. A respiratory rate below 8 per minute was observed in three patients. Due to adequate symptomatic treatment, other moderate and severe symptoms were relatively rare. TTS fentanyl was shown to be an effective, safe and simple method for long-term pain relief in cancer patients and presents an interesting novel option in the treatment of cancer pain.
