To examine the association of risk factors, age, gender, and earlier opioid requirement with the rate of dose escalation in long-term opioid therapy. ⋯ Age, gender, and earlier dose requirement were associated with the rate of dose change in 9-year long-term opioid therapy. Patients aged 75-100 years, being female or having large dose requirement at an earlier stage of therapy may experience a slower dose escalation or even dose decline.

Pain is a prevalent condition that often involves a neuropathic component. Hydrocodone is one of the most widely used opioids for pain but is often associated with side effects (SEs). This study sought to characterize the experience of patients taking hydrocodone for non-cancer pain. ⋯ This study demonstrates an unmet need for better therapeutic options to manage pain, including neuropathic pain. Therapies that offer improved tolerability also may increase adherence, which could affect overall satisfaction and response to pain management.

The purpose of this study was to better quantify how urine drug monitoring (UDM) is used in clinical practice. Little is known about which patients are monitored, how often patients are monitored, which substances are important to detect, and under what circumstances clinicians modify the frequency of monitoring. ⋯ Despite a lack of agreement between guidelines informing the use of UDM, there appears to be a general consensus among practitioners that use UDM on: which patients to monitor, how often to monitor, and which substances are most important to detect.

To develop effective programs for people who are opioid dependent and to impact the opioid epidemic in New York City, it is crucial to monitor attitudes about opioid addiction treatments among opioid users who have experienced barriers to engagement and retention in addiction treatment. ⋯ Both methadone maintenance and buprenorphine treatment opportunities are necessary to address the diverse treatment needs of opioid-dependent people in New York City. However, the current medical model of buprenorphine treatment may be too restrictive for some opioid-dependent people and may be contributing to the use of illicit buprenorphine. New models to deliver buprenorphine treatment may address these problems.

Opioids may cause progressive enhancement of pain sensitivity (opioid-induced hyperalgesia [OIH]) and thus, exacerbate existing pain. Animal studies also demonstrate paradoxical OIH with an ultralow dose (ULD, subanalgesic) of opioid; eg, the μ-opioid, morphine. Repeated administration of ULD-morphine resulted in tolerance to ULD-OIH. Prior exposure to ULD-morphine prolonged subsequent morphine antinociception in intact rats (delay of tolerance) and blocked neuropathic pain in nerve-injured rats (no hyperalgesia). Hence, pre-emptive desensitization of the excitatory function of opioid receptors may reduce further activation of a pain facilitatory system exerted by opioid or nerve injury. ⋯ Pre-emptive use of ULD μ-opioid (not κ-opiod) blocked initiation (not maintenance) of neuropathic pain after CCI in rats. These data may suggest a novel treatment approach in situations when the potential development of neuropathy can be anticipated.
