Second degree burn injury is the most common type of burn injury which usually takes 2-3 weeks for complete healing. However, such patients suffer with intense pain associated with development of hyperalgesia and allodynia. Here, we prepare a silver clay patch using Montmorillonite clay, betaine and silver nitrate. Later, the silver clay patches were loaded with fentanyl. Further, the patches were fabricated into burn wound dressings. The dressings were first subjected to ex vivo skin penetration studies and were later evaluated for thermal hyperalgesia and mechanical allodynia using second degree burn injury rodent model...

Fentanyl is a potent synthetic opioid used as a narcotic analgesic supplement in general and regional anesthesia as well as in management of persistent, severe chronic pain. Alarming epidemiological and forensic medicine reports, accumulated mainly during the last two decades, point to a growing increase in illicit use of fentanyl, mainly in North America and Europe. Toxicological data indicates that fentanyl use is inextricably linked with polydrug use. There are two main sources of fentanyl on the "recreational" drug market...

The transdermal fentanyl patch is widely used to treat cancer-related pain despite its wide inter- and intrapatient variability in pharmacokinetics. The aim of this study was to investigate whether smoking and body size (i.e. body mass index) influence fentanyl exposure in patients with cancer. These are factors that typically change during treatment and disease trajectories. We performed an explorative cohort study in patients with cancer using transdermal fentanyl patches (Durogesic®), by taking a blood sample for pharmacokinetic analysis one day after applying a patch in patients with a stable fentanyl dose...

Background and Objectives: The cutaneous fentanyl patch is widely used to treat continuous pain in patients with cancer. Its use is hampered by a high inter- and intrapatient pharmacokinetic variability. Factors that influence this pharmacokinetic variability are largely unclear. The aim of these studies was to test if common patient variables, i) the use of the moderate CYP3A4 inhibitor aprepitant and ii) the localization of the fentanyl patch (upper arm versus thorax) influence systemic exposure to fentanyl in patients with cancer using a transdermal fentanyl patch...

The increase in opioid prescribing in many European countries over the last decade has raised concerns about associated diversion, overdose, and mortality. Fentanyl is one of these synthetic opioids that is typically prescribed as a transdermal patch for pain that requires continuous pain relief and has been the focus of investigation due to reports of overdose and death. We report a case series of 14 drug addiction treatment entrants, who entered treatment in a service located in the region of Southern Denmark from August 2015 to December 2015 for smoking fentanyl patches...

A 56-year-old man with advanced RCC and a past medical history of type 2 diabetes underwent a radical left nephrectomy following a histological diagnosis of papillary RCC, G2, INF b, pT3, V1 in 1999. In 2008, sorafenib was started to treat multiple pulmonary metastases of RCC. In 2011, sorafenib was switched to sunitinib when radiologic progression was observed. In 2014, sunitinib was switched to axitinib when further radiologic progression was observed. In 2015, the patient was referred to Yazawa clinic for homecare urology when hospital visits became difficult due to cancer pain and bilateral lower-extremity muscle weakness...

Drug tampering practices, with the aim to increase availability of drug delivery and/or enhance drug effects, are accessible on Internet and are practiced by some portion of recreational drug users. Not rarely, recreational misuse may result in toxic and even fatal results. The aim of the present study was to assess the tampering risk of medicaments containing different formulations of an opioid in combination with paracetamol or dexketoprofen, following the procedures reported in dedicated forums on the web...

BACKGROUND: We performed a prospective study to evaluate and compare the effectiveness of postoperative pain control methods after bone surgery in the foot and ankle. METHODS: Among the patients who underwent foot and ankle surgery from June 2014 to September 2015 with an ultrasound-guided nerve block, 84 patients who fully completed a postoperative pain survey were enrolled. An opioid patch (fentanyl patch, 25mg) was applied in group A (30 patients). Diluted anesthetic (0...

Objective: There are no strong guidelines on how long or how we should undertake conservative treatment during the acute period of an osteoporotic vertebral compression fracture (VCF). Methods: We treated 202 patients with conservative treatment on VCF from March 2012 to August 2015. On inclusion criteria, 75 patients (22 males and 53 females) were included in the final analysis. After admission, a transdermal fentanyl patch with low dose (12.5 µg) application was attempted in all patients...

OBJECTIVE: The aim of this study is to investigate the effect of transdermal fentanyl (TDF) as an adjuvant to paravertebral block (PVB) for pain control after breast cancer surgery. PATIENTS AND METHODS: This randomized, double-blind trial included fifty females with breast cancer scheduled for surgery. They were randomly allocated into one of two equal groups. The TDF group used transdermal fentanyl patches (TFPs) 25 μg/h applied 10 h preoperative then PVB with 20 mL of bupivacaine 0...

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...

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...
