Unique pharmacology of tapentadol for treating acute and chronic pain.
Even though pain is a complex process involving many different mediators, enzymes, receptors and ion channels, pain medications usually address only individual targets. Nucynta, which addresses multiple pain targets, was the first new centrally acting analgesic to be approved by the FDA in 2008. ⋯ Although future improved, well-designed prospective, randomized double-blind controlled studies are needed to determine both the relative efficacy of tapentadol and its safety, we believe that tapentadol has the potential to become a uniquely suited opioid medication in the multi-modal management of moderate-to-severe acute and chronic pain conditions.

The use of opioids for both benign and cancer-related chronic pain has increased exponentially over the last few years. For this reason, increasing numbers of such patients are presenting for surgery. ⋯ Patients treated with opioids have special needs in the perioperative setting and it is the anesthesiologist's responsibility to manage these needs optimally. The aim of the present paper is to briefly orient the reader in the management of postoperative pain in patients chronically treated with licit opioids.

Patterns of community-based opioid prescriptions in people dying of cancer.
Studies of opioid use in cancer patients have been cross-sectional or have focused on mean consumption over a specific time interval. ⋯ Patients dying of cancer require increasing doses of opioids over time; although we cannot distinguish the relative contributions of disease progression and opioid tolerance, age and certain cancers seem related to this phenomenon. Given the potentially prohibitive cost of prospective epidemiological studies, more elaborate clinical administrative databases that include regular pain assessment are necessary to determine optimal opioid use and factors associated with dose increases over time at a population level.

Chronic noncancer pain (CNCP) and prescription opioid use is a highly complex and growing health care issue in Canada. Many quantitative research studies have investigated the effectiveness of opioids for chronic pain; however, gaps remain in the literature regarding the personal experience of using opioids and their impact on those experiencing CNCP. ⋯ Although there were many negative aspects to using opioids daily, the positive effects outweighed the negative for most participants and most of the negative aspects were socioculturally induced rather than caused by the drug itself. The present study highlighted the complexities involved in using prescription opioids daily for management of CNCP for individuals living with pain.

A retrospective, matched cohort study of potential drug-drug interaction prevalence and opioid utilization in a diabetic peripheral neuropathy population initiated on pregabalin or duloxetine.
Anticipating and controlling drug-drug interactions (DDIs) in older patients with painful diabetic peripheral neuropaty (pDPN) presents a significant challenge to providers. The purpose of this study was to examine the impact of newly initiated pregabalin or duloxetine treatment on Medicare Advantage Prescription Drug (MAPD) plan pDPN patients' encounters with potential drug-drug interactions, the healthcare cost and utilization consequences of those interactions, and opioid utilization. ⋯ The significantly higher prevalence of potential DDIs and potential cost impact found in pDPN duloxetine users, relative to pregabalin users, underscore the importance of considering DDIs when selecting a treatment.
