This review will provide an overview of pharmacokinetics and clinical practice considerations of the novel formulations of fentanyl for the treatment of breakthrough cancer pain. First, we provide a brief description of the physicochemical properties of fentanyl. ⋯ Advancements in the formulations and delivery of fentanyl have provided a safer and more effective treatment for breakthrough cancer pain. These dosage forms offer overlapping yet distinct pharmacokinetic advantages to allow more choices for physicians and patients in the management of breakthrough cancer pain.

ReviewReview of extended-release formulations of Tramadol for the management of chronic non-cancer pain: focus on marketed formulations.
Patients with chronic non-malignant pain report impairments of physical, social, and psychological well-being. The goal of pain management should include reducing pain and improving quality of life. Patients with chronic pain require medications that are able to provide adequate pain relief, have minimum dosing intervals to maintain efficacy, and avoid breakthrough pain. ⋯ A comparative review of available extended release Tramadol formulations shows that these medications are not equivalent in their pharmacokinetic profile and this may have implications for selecting the optimal therapy for patients with pain syndromes where Tramadol is an appropriate analgesic agent. Differences in pharmacokinetics amongst the formulations may also translate into varied clinical responses in patients. Selection of the appropriate formulation by the health care provider should therefore be based on the patient's chronic pain condition, needs, and lifestyle.

Recognition and management of iatrogenically induced opioid dependence and withdrawal in children.
Opioids are often prescribed to children for pain relief related to procedures, acute injuries, and chronic conditions. Round-the-clock dosing of opioids can produce opioid dependence within 5 days. ⋯ Guidance on this subject is available only for adults and primarily for adults with substance use disorders. The guideline will summarize existing literature and provide readers with information currently not available in any single source specific for this vulnerable pediatric population.

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.

Scientometric assessment of drugs for chronic pain, 1979-2013: rapid growth of publications, paucity of successful drugs.
The aim of this study was to find signs of progress in the pharmacotherapy of chronic pain over the past 35 years using scientometric analysis. The following scientometric indices were used: 1) popularity index, representing the share of articles on a specific drug(s) relative to all articles in the field of chronic pain; 2) index of change, representing the degree of growth in publications on a topic from one period to the next; 3) index of expectations, representing the ratio of the number of articles on a topic in the top 20 journals relative to the number of articles in all (>5,000) biomedical journals covered by PubMed; and 4) index of ultimate success, representing a publication outcome when a new drug takes the place of a common drug previously used for the same purpose. Publications on 55 drugs used in the treatment of chronic pain were assessed during seven 5-year periods, from 1979 to 2013. ⋯ None of the drugs had a high index of expectations in 2009-2013. The index of ultimate success was positive only with triptans in the relatively limited area of acute treatment of migraine. As a result, despite rapid growth in the number of publications, our scientometric analysis did not reveal signs of substantial progress in the field of pharmacotherapy for chronic pain.
