BACKGROUND: Opioid drugs, including fentanyl, are commonly used to treat neuropathic pain, and are considered effective by some professionals. Most reviews have examined all opioids together. This review sought evidence specifically for fentanyl, at any dose, and by any route of administration. Other opioids are considered in separate reviews. OBJECTIVES: To assess the analgesic efficacy of fentanyl for chronic neuropathic pain in adults, and the adverse events associated with its use in clinical trials...

Fentanyl is a strong opioid that is available for various administration routes, and which is widely used to treat cancer-related pain. Many factors influence the fentanyl pharmacokinetics leading to a wide inter- and intra-patient variability. This systematic review summarizes multiple studied factors that potentially influence fentanyl pharmacokinetics with a focus on implications for cancer patients. The use of CYP3A4 inhibitors and inducers, impaired liver function, and heating of the patch potentially influence fentanyl pharmacokinetics in a clinically relevant way...

Opioids given to pregnant and parturient women are relatively freely transferred across the placenta. Spinal, epidural and intravenous fentanyl have been studied in pregnant women and neonates, but foetal safety of fentanyl dosing with transdermal patch during pregnancy and labour is not sufficiently studied. Foetal pH is physiologically lower than maternal pH, and thus, opioids, that are weak bases, are ionized and may cumulate to foetus. Foetal asphyxia may further worsen acidosis and ion trapping induced by low pH is assumed to increase the foetal exposure to opioids...

Postoperative pain is a significant concern for patients who undergo surgery via a midline posterior approach to the occipitocervical junction and spinal axis. The development of the disposable, ambulatory pain pump presents a novel alternative for treatment of postoperative pain. The authors describe a multimodal treatment algorithm for postoperative pain after posterior occipitocervical junction surgery that uses the On-Q pain catheter system (I-Flow Corp., Lake Forest, CA) and a fentanyl patch. The On-Q PainBuster catheter system is a disposable, ambulatory device that allows for continuous anesthetic delivery directly into or adjacent to the wound...

Fentanyl is a μ-opioid agonist that often is used as the analgesic component for balanced anesthesia in both human and veterinary patients. Minimal information has been published regarding appropriate dosing, and the pharmacokinetics of fentanyl are unknown in NHP. The pharmacokinetic properties of 2 transdermal fentanyl delivery methods, a solution (2.6 and 1.95 mg/kg) and a patch (25 μg/h), were determined when applied topically to the dorsal scapular area of cynomolgus macaques (Macaca fascicularis). Serum fentanyl concentrations were analyzed by using liquid chromatography-mass spectrometry...

Poklis and Backer published a survey of the concentrations of fentanyl and norfentanyl that could be expected in urine from patients using Duragesic(®), a transdermal fentanyl patch. That study employed a relatively small number of patient data points and analysis by Gas Chromatography/Mass Spectrometry. This work examines a larger population of patient positives for fentanyl and norfentanyl to determine whether more than a decade later the original report remains accurate in predicting the range and median levels of fentanyl and norfentanyl concentrations physicians can expect to see from their patients...

To date, no studies investigating titration with oral transmucosal fentanyl for the dose-finding of transdermal fentanyl treatment have been published. In an open randomized study 60 patients with chronic malignant (n = 39) or nonmalignant pain (n = 21), who required opioid therapy according to step three of the guidelines of the World Health Organization (WHO), were investigated. In two groups of 30 patients each titration with immediate release morphine (IRM) or oral transmucosal fentanyl citrate (OTFC) was undertaken...

Severe paroxysmal sympathetic overactivity occurs in a subgroup of patients with acquired brain injuries including traumatic brain injury, hypoxia, infection and tumor-related complications. This condition is characterized by sudden increase of heart rate, respiratory rate, blood pressure, body temperature and excessive diaphoresis. The episodes may be induced by external stimulation or may occur spontaneously. Frequent occurrence of this condition could result in secondary morbidities, therefore, should be diagnosed and managed insightfully...

BACKGROUND: Although a convenient opioid delivery system, transdermal fentanyl patches have caused several deaths and resulted in safety warnings reminding prescribers that fentanyl patches should be prescribed only for patients who have adequate prior exposure to opioids. We conducted a longitudinal analysis of the safety of fentanyl initiation by examining past opioid exposure among patients newly prescribed fentanyl patches. METHODS: We identified all patients in the province of Manitoba who were newly prescribed fentanyl patches between Apr...

BACKGROUND: There has been a significant spike in fentanyl-related deaths from illicit fentanyl supplied via the heroin trade. Past fentanyl access was primarily oral or dermal via prescription fentanyl patch diversion. One factor potentially driving this increase in fatalities is the change in route of administration. Rapid intravenous (IV) fentanyl can produce chest wall rigidity. We evaluated post-mortem fentanyl and norfentanyl concentrations in a recent surge of lethal fentanyl intoxications...

UNLABELLED: Prescription opioid abuse and diversion are major causes of morbidity and mortality in the United States. The buprenorphine transdermal delivery system (BTDS) is indicated for the treatment of moderate to severe chronic pain and provides a continuous dose of 5, 7.5, 10, 15, or 20 μg/h buprenorphine for 7 days. Quarterly rates of abuse and diversion of BTDS were compared with 4 comparator groups: 1) other buprenorphine products, 2) fentanyl patches, 3) extended-release (ER) opioid tablets/capsules, and 4) ER tramadol...

BACKGROUND : Transdermal therapeutic system fentanyl with a drug release rate of 12 µg/h should be of special value in pediatric cancer pain control. Such a fentanyl formulation allows for a stepwise dose increase, similar to that reported for sustained-release morphine. PATIENTS AND METHODS : Sixty-four male and female pediatric patients with moderate to severe chronic cancer pain, ages ranging 2-14 years, were included. Patients did not receive opioids prior to enrollment. Patients were observed for pain relief using the Visual Analog Scale and the Wong-Baker FACES Pain Rating Scale, play performance score, and for side effects...
