AIMS: To describe consumption trends of three groups of analgesics (non-opioids, mild and strong opioids) between 2006 and 2015 in France, and compare this pattern of use with six European countries in 2015. METHODS: Annual drugs sales were extracted from the French national authority's consumption database and from the IMS-MIDAS and national databases for European countries. RESULTS: The use of mild opioids in France decreased by 53% during the last 10 years due to the declining use of dextropropoxyphene combinations, along with an increase in the use of non-opioids and strong opioids (from 72 to 93 and 2 to 2...

Background: Cancer-related neuropathic pain is sometimes unresponsive to multidrug treatment. Novel drugs are required to treat such severe pain without necessitating the use of adjuvant analgesics. Tapentadol is a new drug that has a dual mechanism as both an opioid agonist and noradrenalin reuptake inhibitor. The study objective was to investigate the effectiveness of oral tapentadol for relieving cancer-related neuropathic pain. Methods: A retrospective, single-center, open, non-randomized study was conducted at the Nagoya City University Hospital...

The use of strong opioids for the treatment of chronic non-cancer pain (CNCP) has gained undisputed acceptance among specialists and should be considered when other pharmacological treatments are not effective or cause serious side effects. However, drugs from the third step of analgesic ladder still raise concerns among doctors and patients in the case of long-term therapy. A CASE REPORT: The authors present reports of three cases of patients with CNCP caused by musculoskeletal disorders and numerous comorbidities...

Fentanyl and its derivatives sufentanil, alfentanil, and remifentanil are potent opioids. A comprehensive review of the use of fentanyl and its derivatives in the pediatric population was performed using the National Library of Medicine PubMed. Studies were included if they contained original pharmacokinetic parameters or models using established routes of administration in patients younger than 18 years of age. Of 372 retrieved articles, 44 eligible pharmacokinetic studies contained data of 821 patients younger than 18 years of age, including more than 46 preterm infants, 64 full-term neonates, 115 infants/toddlers, 188 children, and 28 adolescents...

BACKGROUND: Two decades ago, there were only single case reports on deaths in Europe following the consumption of illicitly manufactured fentanyl by problem drug users. Today, lethal fentanyl intoxication is now no longer a rarity. Since 2005, a rapid increase of lethal fentanyl-related intoxications in the drug scene has been observed at the Institute of Legal Medicine, Ludwig Maximilians University, Munich. We hypothesized that this rise is the result of the launch of fentanyl matrix patches in Germany in 2004, their broad acceptance, their diversion from the regulated supply chain, and incautious prescription by medical care providers...

BACKGROUND: Opioids are the most important pharmacological treatment for moderate-to-severe cancer pain, but side effects limit their use. Transdermal fentanyl (TDF) and oral prolonged-release oxycodone-naloxone (OXN-PR) are effective in controlling chronic pain, with less constipation compared to other opioids. However, TDF and OXN-PR have never been directly compared. PATIENTS AND METHODS: Cancer patients with moderate-to-severe chronic pain were consecutively enrolled in two prospective 28-day trials, received either TDF or OXN-PR, and were assessed at baseline and after 7, 14, 21, and 28 days...

Sheep used as surgical models require appropriate pain management, and the commonly used transdermal fentanyl patches require a long predosing period to achieve adequate plasma concentrations. The aim of this study was to assess the pharmacokinetic parameters of an FDA-approved transdermal fentanyl solution (TFS) that has yet to be tested in sheep. In this study, we compared TFS at 2.7 mg/kg (n = 2), 1.7 mg/kg (n = 3), and 0.5 mg/kg (n = 3) with the control fentanyl patch at 2 μg/kg/h (n = 1); both products were applied topically to the intrascapular region...

Treatment of cancer pain is generally based on the three-step World Health Organization (WHO) pain relief ladder, which utilizes a sequential approach with drugs of increasing potency. Goals of pain management include optimization of analgesia, optimization of activities of daily living, minimization of adverse effects, and avoidance of aberrant drug taking. In addition, it is recommended that analgesic regimens are individualized and simplified to help ensure patient compliance and should provide the least invasive, easiest, and safest route of opioid administration to ensure adequate analgesia...
