Safety and effectiveness of intravenous morphine for episodic (breakthrough) pain using a fixed ratio with the oral daily morphine dose
2003
Breakthrough pain is normally severe in intensity and has a rapid onset. The availability of supplemental doses of opioids (rescue medication) in addition to the continuous analgesic medication is the main treatment suggested to manage these pain flares. The intravenous (i.v.) route may provide analgesia fast enough, but has never been assessed in clinical studies. The aim of this open-label study was to verify the safety and effectiveness of an i.v. dose equal to one-fifth the calculated equianalgesic total daily dose in advanced cancer patients with episodic pain. A consecutive sample of 48 cancer patients treated with oral morphine, who reported an acceptable basal analgesia and reported…
Intravenous morphine for breakthrough (episodic-) pain in an acute palliative care unit: a confirmatory study.
2007
The aim of this prospective cohort study was to confirm the safety of intravenous morphine (IV-M) used in doses proportional to the basal opioid regimen for the management of breakthrough pain and to record the nurse compliance on regularly recording data regarding breakthrough pain treated by IV-M. Over a one-year period, 99 patients received IV-M for breakthrough pain during 116 admissions. The IV-M dose was 1/5 of the oral daily dose, converted using an equianalgesic ratio of 1/3 (IV/oral). For each episode, nurses were instructed to routinely collect changes in pain intensity and emerging problems when pain became severe (T0), and to reassess the patient 15minutes after IV-M injection (…
Equipotent doses to switch from high doses of opioids to transdermal buprenorphine.
2008
INTRODUCTION: The aim of this study was to evaluate the equianalgesic ratio of transdermal buprenorphine (TD BUP) with oral morphine and TD fentanyl in a sample of consecutive cancer patients receiving stable doses of 120-240 mg of oral morphine or 50-100 microg of TD fentanyl, reporting adequate pain and symptom control. MATERIALS, METHODS, AND RESULTS: Patients receiving daily stable doses of opioids for more than 6 days, with no more than two doses of oral morphine (20 and 40 mg, respectively) as needed, were switched to TD BUP using a fentanyl-BUP ratio of 0.6:0.8 and an oral morphine-BUP ratio of 70:1. Opioid doses, pain and symptom intensity, global satisfaction, and number of breakth…
Switching from Transdermal Drugs: An Observational "N of 1" Study of Fentanyl and Buprenorphine
2007
The aim of this study was to confirm that the concomitant presence of transdermal fentanyl (TTS FE) and buprenorphine (TTS BU) may be feasible without important consequences, using doses presumed to be equianalgesic. A prospective "N of 1" study was carried out in a sample of volunteers with cancer pain receiving stable doses of TTS FE or TTS BU, with adequate pain and symptom control. In the study design, each patient provided data before and after a switch from one opioid to the other and then back to the previous one. Sixteen patients receiving daily stable doses of 0.6 or 1.2 mg of TTS FE were switched to TTS BU using an FE-BU ratio of 0.6-0.8. After three days, the TTS BU patch was rem…
Conversion ratios for opioid switching in the treatment of cancer pain: a systematic review
2011
In this paper we describe the results of a systematic search of the literature on conversion ratios during opioid switching. This is part of a project of the European Palliative Care Research Collaboration to update the European Association for Palliative Care recommendations for the use of opioid analgesics in the treatment of cancer pain. Studies were eligible for inclusion if they involved adult patients with chronic cancer pain, contained data on opioid conversion ratios, were prospective and were written in English. Thirty-one studies were identified and included. The majority of the studies had methodological flaws and were not designed to explore or demonstrate equianalgesic dose da…
