Opioids are effective for severe pain; however, the safety issue is also a primary concern. To better understand the opioid use in Taiwan, we conducted this study. ⋯ The total number of opioid prescriptions in Taiwan gradually increased annually, among which morphine was the most commonly used opioid. Cancer patients consumed more opioid prescriptions than noncancer patients and most of the prescriptions in noncancer patients were used in acute pain service. The number of prescriptions increased with the age of the patients in both cancer and noncancer patients. The low prescription rate of opioids in chronic pain in Taiwan is not similar as those in high opioid-consuming countries, such as United States.

Increases in opioid prescribing contributed to the opioid epidemic in the U.S. Subsequent efforts to promote safer use of opioids for treating pain included augmenting prescription drug monitoring programs and prescribing guidelines. The purpose of this study is to characterize the distribution of opioids dispensed in the U.S. by specialty. ⋯ During a period in which prescribing interventions were expanded, opioid prescribing declined overall, although not uniformly by specialty.

Opioids are not universally effective for treating neuropathic pain following spinal cord injury (SCI), a finding that we previously demonstrated in a rat model of SCI. The aim of this study was to determine analgesic response of morphine-responsive and nonresponsive SCI rats to adjunct treatment with dopamine modulators and to establish if the animal groups expressed distinct metabolomic profiles. Thermal thresholds were tested in female Long Evans rats (N = 45) prior to contusion SCI, after SCI and following injection of morphine, morphine combined with dopamine modulators, or dopamine modulators alone. ⋯ The data suggest an overall benefit of the D3 receptor system in improving analgesia, and an association between morphine responsiveness and metabolomic changes in the tyrosine/dopamine pathways in striatum and spinal cord. PERSPECTIVE: Spinal cord injury (SCI) leads to opioid-resistant neuropathic pain that is associated with changes in dopamine metabolomics in the spinal cord and striatum of rats. We present evidence that adjuvant targeting of the dopamine system may be a novel pain treatment approach to overcome opioid desensitization and tolerance after SCI.

To investigate the holistic characteristics of patients administered or prescribed opioids to treat pain in the emergency department (ED). ⋯ Despite increasing awareness of potential implicit bias in managing pain in the ED, racial disparities in OAP still existed. More education and training on implicit bias would help with reduce the disparities. Also, our study result indicated that non-clinical factors may play a role in emergency physicians' decision making in OAP. Increased recognition of the variation and systemic efforts to address factors affecting the variability are needed.

Amidst the opioid epidemic, there has been an increasing focus on opioid utilization in U.S. emergency departments (EDs). Compared with other opioids, little is known about the use of tramadol over the past decade. Tramadol has uncertain efficacy and a concerning adverse effect profile compared with traditional opioids. ⋯ Although the use of traditional opioids decreased from 2007 to 2018, the use of tramadol increased. Increases were largest among older patients, who may be more susceptible to the adverse effects associated with this medication. Further research in the appropriate use of tramadol in the ED setting is warranted.
