PURPOSE: At elevated temperatures, the rate of drug release and skin permeation from transdermal delivery systems (TDS) may be higher than at a normal skin temperature. The aim of this study was to compare the effect of heat on the transdermal delivery of two model drugs, nicotine and fentanyl, from matrix-type TDSs with different formulations, using in vitro permeation tests (IVPT). METHODS: IVPT experiments using pig skin were performed on two nicotine and three fentanyl TDSs...

Rhesus macaques (Macaca mulatta) are the most commonly used NHP biomedical model and experience both research andclinical procedures requiring analgesia. Opioids are a mainstay of analgesic therapy. A novel, transdermal fentanyl solution(TFS) has been developed as a long-acting, single-administration topical opioid and was reported to provide at least 4 d ofeffective plasma concentrations in beagles (Canis familiaris). To evaluate the pharmacokinetic profile of TFS in healthy adultrhesus macaques, we used a 2-period, 2-treatment crossover study of a single topical administration of 1...

Providing appropriate analgesia is an important concern in any species. Fentanyl, a μ-receptor specific opioid, use is common in mammalian species but has been incompletely evaluated for this purpose in avian species. Transdermal fentanyl patches were applied to domestic chickens (n = 10) of varying breeds for 72 hours. Repeated blood samples were collected from the birds to assess time-concentration of fentanyl and norfentanyl in plasma, as assayed by liquid chromatography-mass spectrometry, throughout patch application and for 48 hours after patch removal...

REVIEW
Stephan A Schug, Sonya Ting
Fentanyl is a synthetic, highly selective opioid with many desirable physicochemical properties, including a high lipophilicity and predictable pharmacokinetics. These properties have an established record in the management of pain in a variety of settings, particularly acute pain and breakthrough cancer pain. Fentanyl was initially developed for parenteral use; however, this is invasive and impractical in the outpatient setting. Unfortunately, the high first-pass metabolism of fentanyl makes oral formulations unfeasible...

OBJECTIVES: To evaluate the relative clinical efficacy, safety, and tolerability associated with two non-invasive patient-controlled analgesia (PCA) treatments, sufentanil sublingual tablet system (SSTS) and fentanyl iontophoretic patient-controlled transdermal system (PCTS). These two treatments have recently been approved in the EU for the management of acute moderate-to-severe post-operative pain in adult patients. METHODS: As no head-to-head trials comparing SSTS and PCTS currently exist, indirect treatment comparison (ITC) analyses were conducted to evaluate SSTS or PCTS versus intravenous (IV) morphine PCA...

REVIEW
Sebastiano Mercadante
Patients with chronic pain often develop dysphagia during the course of an advanced disease such as cancer. Opioids are the cornerstone of the management of cancer pain and are commonly administered orally. However, the oral route does not suit patients with dysphagia, who require alternative methods to administer analgesic drugs. Opioids given by parenteral or transdermal routes provide adequate pain control, being at least as efficacious as the oral route, but knowledge and experience in conversion ratios are mandatory when using these routes of administration...

217 Background: Uncontrolled pain is one of the main fears for patients with cancer and their families. Opioid analgesics are highly effective agents, but the choice of type, route, and dose needs to be personalized. The highly cost of some of them can make it difficult for patients to received adequate pain control without appropriate insurance coverage. There is a lack of information regarding the frequency of denials or heavy copayments by insurers. METHODS: We evaluated 143 continuous opioid test claims for prescriptions by our palliative care providers for opioids other than morphine, including transdermal fentanyl, extended release oxycodone, hydromorphone and oxymorphone...

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs), transdermal fentanyl patches, and transmucosal buprenorphine are probably the most commonly used options for providing post-operative analgesia in the early at-home period. However, these require daily administration or are associated with abuse concerns. One of the significant unmet needs in veterinary surgery and pain management is for longer acting opioids for cats to effectively bridge the gap between the in-hospital and at-home recovery periods...

BACKGROUND: A reliable biomarker for quantifying pain or hyperalgesia has yet to be found. A surrogate marker of arginine vasopressin, copeptin, is elevated in a number of states of physiological and psychological stress and may have a role in quantifying pain and/or hyperalgesia. OBJECTIVES: To evaluate copeptin as a biomarker for pain or hyperalgesia developing after 120 min of sustained electrical stimulation. DESIGN: Secondary analysis of a randomised, double-blinded, crossover trial...

Here, we present a somewhat unusual suicide attempt where, despite an unbelievable overdose with transdermal fentanyl patches, the patient survived. The patient-a woman aged 70 years, who has suffered from chronic back pain despite starting transdermal fentanyl patches in 2007. The unconventional method of attempted suicide was based on online research into deaths from fentanyl patch toxicity. She had gradually accumulated 100 µg fentanyl patches from repeat prescriptions, applying 14 patches with fatal intent, alongside 2 45 mg mirtazapine tablets, and concurrent therapeutic doses of tramadol and morphine sulfate oral solution...

INTRODUCTION: Postoperative pain management can be challenging in patients with a high body mass index (BMI) especially as a result of poor venous access and delayed ambulation that can result in serious complications. Fentanyl iontophoretic transdermal system (ITS) is a needle-free, patient-controlled analgesic method available for use in acute postoperative pain. The primary objective of these analyses was to determine if there were any differences between patients with high BMI (>40 kg/m(2)) and lower BMIs (<30 kg/m(2) and 35-40 kg/m(2)) in terms of efficacy or safety...
