title: [Parenteral opioids in end-of-life care in cancer patients].
abstract: The ethical obligation to relieve pain and other distressing symptoms in patients with cancer is now receiving increasing attention and concern in palliative and end-of-life care. The vast majority of patients with cancer pain are prescribed opioids in oral formulation. However, a patient at the end of his or her life often needs parenteral administration of opioids as the medical condition deteriorates, irrespective of using sedatives. Controlled release opioid preparations currently available in Japan are CR morphine sulphate, CR oxycodone and transdermal fentanyl patch. The opioids available in injectable preparations are morphine HCL and fentanyl citrate. Accordingly, not only the guideline for switching opioids, so-called "opioid rotation," but the guideline for changing the opioid administration route is also necessary in end-of-life care. The authors specifically indicate when and how to convert opioid administration from the oral to the parental route.
