Low doses of transdermal buprenorphine in opioid-naive patients with cancer pain: A 4-week, nonrandomized, open-label, uncontrolled observational stu…
2009
OBJECTIVE: The aim of this study was to evaluate the effect and tolerability of low doses of transdermal (TD) buprenorphine patches in opioid-naive patients with cancer pain. METHODS: This was a nonrandomized, open-label, uncontrolled study in consecutive opioid-naive patients with advanced cancer and moderate pain. TD buprenorphine was initiated at a dose of 17.5 microg/h (0.4 mg/d), with patch changes every 3 days. Doses were then adjusted according to the clinical response. Pain intensity, opioid-related adverse effects, TD buprenorphine doses, and quality of life were monitored over 4 weeks. The time to dose stabilization and indexes of dose escalation were also calculated. RESULTS: Thi…
Safety and effectiveness of intravenous morphine for episodic breakthrough pain in patients receiving transdermal buprenorphine.
2006
Supplemental dosing of an opioid is the main treatment suggested to manage breakthrough pain in cancer patients. The intravenous route has been proven to be safe and effective, providing rapid analgesia in patients receiving oral morphine. Transdermal buprenorphine (TTS-BUP) is increasingly used in cancer pain management, but this drug has been labeled as a difficult drug to use in combination with other opioids. The aim of this open-label study was to verify the safety and effectiveness of intravenous morphine (IV-MO) for the treatment of episodic pain in cancer patients receiving TTS-BUP. A consecutive sample of 29 cancer patients, who were treated with TTS-BUP, reported an acceptable bas…
‘Not at all what I had expected’: Discontinuing treatment with extended-release naltrexone (XR-NTX): A qualitative study
2021
Background: Extended-release naltrexone (XR-NTX), an opioid antagonist, has demonstrated equal treatment outcomes, in terms of safety, opioid use, and retention, to the recommended OMT medication buprenorphine. However, premature discontinuation of XR-NTX treatment is still common and poorly understood. Research on patient experiences of XR-NTX treatment is limited. We sought to explore participants' experiences with discontinuation of treatment with XR-NTX, particularly motivation for XR-NTX, experiences of initiation and treatment, and rationale for leaving treatment. Methods: We conducted qualitative, semi-structured interviews with participants from a clinical trial of XR-NTX. The study…
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…
Long term outcomes of pharmacological treatments for opioid dependence: does methadone still lead the pack?
2014
The aim of this review was to update and summarize the scientific knowledge on the long term outcomes of the different pharmacological treatment options for opioid dependence currently available and to provide a critical discussion on the different treatment options based on these results. We performed a literature search using the PubMed databases and the reference lists of the identified articles. Data from research show that the three pharmacological options reviewed are effective treatments for opioid dependence with positive long term outcomes. However, each one has its specific target population and setting. While methadone and buprenorphine are first line options, heroin-assisted tre…
Pharmacokinetic Characterization and External Evaluation of a Quantitative Framework of Sublingual Buprenorphine in Patients with an Opioid Disorder …
2020
Background: The aim of this analysis was to characterize the pharmacokinetics (PK) of sublingual buprenorphine (BUP) and its metabolites (buprenorphine glucuronide
Methadone versus buprenorphine: data detected from Caltanissetta SER.T
2020
In last years, heroin-addicted have exponentially increased: this has made it necessary to identify a pharmacological strategy as effective as possible. With this purpose, a statistical investigation was conducted in a sample of individuals, aged between 18 and 50. They were diagnosed and subjected to different treatments at Ser.T of Caltanissetta (Sicily-Italy) during the period 2013-2017. The analyzed patients were treated with three different pharmacological therapy: methadone 0.1%, methadone 0.5%, buprenorphine and suboxone. We obtained percentages of responders, low responders and non-responders patients from data processing, based on used therapy. Considering pharmacological responses…
Clinical management of drug-drug interactions in HCV therapy: Challenges and solutions.
2013
Contains fulltext : 118153.pdf (Publisher’s version ) (Open Access) Hepatitis C virus (HCV) infected patients often take multiple co-medications to treat adverse events related to HCV therapy, or to manage other co-morbidities. Drug-drug interactions associated with this polypharmacy are relatively new to the field of HCV pharmacotherapy. With the advent of the direct-acting antivirals telaprevir and boceprevir, which are both substrates and inhibitors of the cytochrome P450 (CYP) 3A iso-enzyme, knowledge and awareness of drug-drug interactions have become a cornerstone in the evaluation of patients starting and continuing HCV combination therapy. In our opinion, an overview of conducted dr…
Prolonged-release buprenorphine formulations: Perspectives for clinical practice
2020
International audience; Buprenorphine and methadone are the two main opioid agonist treatments approved for opioid use disorder. Buprenorphine is a partial agonist of the mu opioid receptors, which has been merely available through sublingual form until now. In practice, the use of buprenorphine is smoother than that of methadone, and it induces reduced risks of overdose. However, sublingual buprenorphine also exposes to risks (e.g., withdrawal, misuse) and constraints (e.g., daily intake). Three new galenic formulations of prolonged-release buprenorphine (PRB) are being commercialized and should allow some improvements in patients' comfort and safety. This narrative review aims to describe…
