Multicenter Study Clinical TrialHigh dosage of a fixed combination oxycodone/naloxone prolonged release: efficacy and tolerability in patients with chronic cancer pain.
Opioids are associated with side effects in the treatment of moderate-to-severe chronic cancer pain. Oral combination of opioid agonist-antagonist oxycodone-naloxone (OXN-PR) attenuates gastrointestinal side effects; however, evidence on high-dose OXN-PR treatment is scant. This study evaluates the efficacy and tolerability of high-dose OXN-PR in chronic cancer pain. ⋯ OXN-PR was highly effective and well tolerated even at high doses in cancer patients with chronic pain. The agonist-antagonist combination rapidly alleviated pain and its impact on life style, reducing the number of BTCP and improving opioid side effects.

The anti-inflammatory effects of statins have been suggested to relieve postoperative pain. This retrospective study tested the association between the perioperative routine use of statins in therapeutic doses, and opioid requirements and pain scores, after hip replacement surgery. ⋯ This is the first large retrospective clinical study that investigates the effects of statin use on postoperative pain and opioid consumption. We observed no difference between statin users and non-users during the initial 72 h after hip surgery. Our findings do not support the routine use of statins as part of an analgesic regimen.

As pain is often a comorbid condition, many patients use opioid analgesics in combination with several other drugs. This implies a generally increased risk of drug interactions, which along with inherent pharmacogenetic variability and other factors may cause differences in therapeutic response of opioids. ⋯ Drug interactions and pharmacogenetic differences may lead to therapeutic failure or serious side effects of opioid analgesics. Many interactions involve combinations with antidepressants and antiepileptics, which are highly relevant drugs in patients suffering from pain. To prevent unfavourable drug interactions it is important that clinicians pay close attention and use electronic drug interaction checkers when treatments are initiated or discontinued. For the management of issues related to pharmacogenetic differences, blood-based CYP genotyping is available as routine test at many laboratories, and provide a valuable tool for proper choice of drugs and doses for treatment of pain and other diseases.

Randomized Controlled Trial
Taking the alternative route: Women's experience of intranasal fentanyl, subcutaneous fentanyl or intramuscular pethidine for labour analgesia.
To compare women's experience of receiving either intranasal fentanyl, subcutaneous fentanyl or intramuscular pethidine for labour analgesia. ⋯ For women requesting parenteral analgesia, fentanyl administered by less invasive routes offers women additional options that may better meet their emotional, cognitive and physical needs than the current practice of administering intramuscular pethidine.

This study aimed to describe utilization of opioid medications among infants, children, and adolescents on the inpatient setting. These data are needed to guide clinical trials and improve research methodologies, as well as to inform more about possible sources of opioid misuse in the United States. A retrospective chart review was conducted covering a span of 1 year, with a special focus on the prescription of opioids for long-term treatment of chronic pain. ⋯ Among those who were prescribed opioids for >14 days, the focus was often for reasons other than pain. These data indicate that models of chronic pain that may be utilized in clinical trials of longer-term opioid usage in pediatrics are exceedingly limited. In addition, the patterns of utilization indicate that opioid administration among pediatric inpatients is not a likely contributory factor to concerns about opioid misuse in the United States.
