Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria PAIN Rules for pain management regular administration according to a fixed schedule the schedule for administering morphine is determined by the duration of action individual dosage possible combination with non-opioids and/or adjuvants never combine step-2 and step-3 opioids avoid side-effects by using concomitant medication administration of opioids orally or transcutaneously

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Durogesic ® Why Fentanyl ?  Fentanyl has a selective, high affinity for the μ-opioid receptor  100 times more potent than morphine  highly lipid-soluble  low molecular weight suitable for transdermal administration

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Durogesic ® Schema of the delivery system Administration of TTS fentanyl every 72 hours provides a sustained serum fentanyl concentration more conveniently than intravenous or subcutaneous opioids. Fentanyl TTS is composed of 4 layers plus a removable protective lining. Occlusive backing Drug reservoir Release membrane Contact adhesive Protective peel strip

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Durogesic ® Dosage  Opioid-naíve patients  Conversion of patients from other opioids to fentanyl TTS

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Durogesic ® Opioid-naíve patients  Start on 25μg/h fentanyl TTS.  Maintainace of previous analgesic medication during the first hours is recommended.  Adequate rapid-onset, short-action rescue medication, such as immediate release oral morphine, should be availbale.  The first titration should be at least 3 days after initial patch application.  Subsequent titration at 3- to 6-day intervals.  Upward titration increments should be based on the daily supplementary analgesia requirements; a ratio of 25μg/h fentanyl TTS to 90 mg/24 hours of oral morphine is recommended.

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Durogesic ® Conversion of patients from other opiods to fentanyl TTS

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Durogesic ® Dosage  Adequate rapid-onset, short-action rescue medication, such as immediate release oral morphine, should be available in all patients who receive long-acting opioids.  Not all patients will achieve acceptable analgesia on he 72-hour administration regimen; some may require more frequent (i.e. 48-hour) patch replacement.  The maximum number of patches is determined by the area of suitable skin available for application.

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Durogesic ® Interaction with other agents - centrally acting drugs (sedatives, anaesthetics, hypnotics, transquillizer, skeletal muscle relaxants, other opioids,...): increase toxicity - partially antogonists ( Pentazozin, Buprenorphin ): reduces the effect of fentanyl TTS - Alcohol: increases sedation

Clinical Division of Oncology Department of Medicine I Medical University of Vienna, Austria Conclusions Pain is a significant health problem currently undertreated. Opioids are the mainstay in pharmacological treatment of chronic, moderate-to-severe pain. Choosing an appropriate opioid and delivery route is important for optimal pain relief. Fentanyl TTS is clinically proven to be effective in treating different types of chronic non-cancer pain.
