Review Meta Analysis
Systematic literature review and meta-analysis of the efficacy and safety of prescription opioids, including abuse-deterrent formulations, in non-cancer pain management.
This study was conducted to compare safety and efficacy outcomes between opioids formulated with technologies designed to deter or resist tampering (i.e., abuse-deterrent formulations [ADFs]) and non-ADFs for commonly prescribed opioids for treatment of non-cancer pain in adults. ⋯ ADFs and non-ADFs had comparable efficacy and safety profiles, while both were more efficacious than placebo in reducing pain intensity.

ReviewClinical potential of naloxegol in the management of opioid-induced bowel dysfunction.
Opioid-induced bowel dysfunction (OIBD) is a burdensome condition which limits the therapeutic benefit of analgesia. It affects the entire gastrointestinal tract, predominantly by activating opioid receptors in the enteric nervous system, resulting in a wide range of symptoms, such as reflux, bloating, abdominal cramping, hard, dry stools, and incomplete evacuation. The majority of studies evaluating OIBD focus on constipation experienced in approximately 60% of patients. ⋯ In this review, the prevalence and pathophysiology of OIBD is presented. As PAMORAs seem to be a promising approach, their potential effect is reviewed with special focus on naloxegol's pharmacological properties, data on safety, efficacy, and patient-focused perspectives. In conclusion, as naloxegol is administered orally once daily, has proven efficacious compared to placebo, has an acceptable safety profile, and can be used as add-on to existing pain treatment, it is a welcoming addition to the targeted treatment possibilities for OIBD.

Discrepancies in prevalence estimates in two national surveys for nonmedical use of a specific opioid product versus any prescription pain reliever.
There is a growing need to understand trends in nonmedical use of prescription pain relievers as a class, as well as specific opioid products. Surveys such as monitoring the future (MTF) and the National Survey on Drug Use and Health (NSDUH) are important tools for understanding trends in abuse of prescription and illegal drugs. This report compares discrepancies in prevalence between these surveys for a specific opioid product (oxycodone) relative to other drugs. ⋯ The discrepancy between surveys in prevalence estimates for nonmedical use of oxycodone exceed those for other drugs, pointing to the importance of visual aids and items used to measure the nonmedical use of specific products.

Randomized Controlled Trial Comparative Study
Pregabalin Vs. Opioids for the Treatment of Neuropathic Cancer Pain: A Prospective, Head-to-Head, Randomized, Open-Label Study.
Neuropathic cancer pain (NCP) is a common manifestation of cancer and/or its treatment. Treatment following the WHO analgesic ladder provides relief for the majority of cancer pain patients; however, concern remains that opioids may be less efficacious for neuropathic pain (NP) compared with nociceptive pain, often necessitating the use of higher doses. Adjuvants, such as pregabalin, have shown to be efficacious for the treatment of NP, although data come mostly from noncancer studies. The comparative efficacy and safety of opioids versus adjuvants has not been studied for NCP. The aim of this study was to directly compare pregabalin versus a strong opioid for the treatment of NCP. ⋯ Prompt use of a neuropathic pain-specific adjuvant, such as pregabalin, in NCP may lead to better control of the neuropathic component, with opioid-sparing effects.

ReviewDosing considerations with transdermal formulations of fentanyl and buprenorphine for the treatment of cancer pain.
Opioids continue to be first-line pharmacotherapy for patients suffering from cancer pain. Unfortunately, subtherapeutic dosage prescribing of pain medications remains common, and many cancer patients continue to suffer and experience diminished quality of life. A large variety of therapeutic options are available for cancer pain patients. ⋯ Based on the limited data available, there is significant interpatient variability with transdermal buprenorphine and equipotency recommendations from oral morphine of 75:1-110:1 have been suggested. Cancer patients may require larger transdermal buprenorphine doses to control their pain and may respond better to a more aggressive 75-100:1 potency ratio. This review outlines the prescribing of transdermal fentanyl and transdermal buprenorphine including how to safely and effectively convert to and use them for those with cancer pain.
