ReviewEmerging Medications and Strategies in Acute Pain Management: Evolving Role of Novel Sodium and Calcium Channel Blockers, Peptide-Based Pharmacologic Drugs, and Non-Medicinal Methods.
The present investigation evaluated integration of novel medication technology to enhance treatment options, while improving patient outcomes in acute pain management. In this regard, we focused on determining the role of development and utilization of cutting-edge pharmaceutical advancements, such as targeted drug delivery systems, as well as non-pharmacologic interventions in addressing acute pain states. Further research in this area is warranted related to the need for increased patient comfort and reduced adverse effects. ⋯ Recent innovations and techniques are discussed including pharmacologic drugs targeting sodium and calcium channels, peptide-based pharmacologic drugs, and non-medicinal methods of alleviating pain such as soothing music or virtual reality. The present investigation included review of current literature on the application of these innovative technologies, analyzing mechanisms of action, pharmacokinetics, and clinical effectiveness. Our study also investigated the potential benefits in terms of pain relief, reduced side effects, and improved patient adherence. The research critically examines the challenges and considerations associated with implementing these technologies in acute pain management, considering factors like cost, accessibility, and regulatory aspects. Additionally, case studies and clinical trials are highlighted which demonstrate practical implications of these novel medication technologies in real-world scenarios. The findings aim to provide healthcare professionals with a comprehensive understanding of the evolving landscape in acute pain management while guiding future research and clinical practices toward optimizing their use in enhancing patient care.

Randomized Controlled Trial
Single-Dose Intraoperative Methadone for Pain Management in Pediatric Tonsillectomy: A Randomized Double Blind Clinical Trial.
More than 500,000 elective tonsillectomies are performed in U.S. children annually. Pain after pediatric tonsillectomy is common, often severe, and undertreated. There is no consensus on the optimal management of perioperative tonsillectomy pain. Methadone, with an elimination half-life of 1 to 2 days, has a longer duration of effect than short-duration opioids such as fentanyl. The primary objective of this study was to investigate the intraoperative use of methadone for pediatric tonsillectomy. It tested the hypothesis that methadone would result in less postoperative opioid use compared with short-duration opioids in children after tonsillectomy. ⋯ This small initial study in children undergoing tonsillectomy found that single-dose intraoperative methadone at 0.15 mg/kg age ideal body weight was opioid-sparing compared with intermittent fentanyl.

Randomized Controlled Trial
Characterizing the opioidergic mechanisms of repetitive transcranial magnetic stimulation-induced analgesia: a randomized controlled trial.
Repetitive transcranial magnetic stimulation (rTMS) is a promising technology to reduce chronic pain. Investigating the mechanisms of rTMS analgesia holds the potential to improve treatment efficacy. Using a double-blind and placebo-controlled design at both stimulation and pharmacologic ends, this study investigated the opioidergic mechanisms of rTMS analgesia by abolishing and recovering analgesia in 2 separate stages across brain regions and TMS doses. ⋯ In the DLPFC, double but not the first TMS session induced significant pain reduction in the saline condition, resulting in less pain compared with the naloxone condition. In addition, TMS over the M1 or DLPFC selectively increased plasma concentrations of β-endorphin or encephalin, respectively. Overall, we present causal evidence that opioidergic mechanisms are involved in both M1-induced and DLPFC-rTMS-induced analgesia; however, these are shaped by rTMS dosage and the release of different endogenous opioids.

Multicenter Study
Patterns of opioid use after surgical discharge: a multicentre, prospective cohort study in 25 countries.
Excessive opioid prescribing following surgery contributes to the growing opioid crisis. Prescribing practices are modifiable, yet data to guide appropriate prescription of opioids at surgical discharge remain sparse. This study aimed to evaluate factors associated with opioid consumption following discharge from surgery. ⋯ Our data suggest that the current quantities of opioids provided at discharge exceed patient needs and may contribute to increasing community opioid use and circulation.

Sirtuin 3 Mediated by Spinal cMyc-Enhancer of Zeste Homology 2 Pathway Plays an Important Role in Human Immunodeficiency Virus-Related Neuropathic Pain Model.
Clinical data demonstrate that chronic use of opioid analgesics increases neuropathic pain in people living with human immunodeficiency virus (HIV). Therefore, it is important to elucidate the molecular mechanisms of HIV-related chronic pain. In this study, we investigated the role of the transcription factor cMyc, epigenetic writer enhancer of zeste homology 2 (EZH2), and sirtuin 3 (Sirt3) pathway in HIV glycoprotein gp120 with morphine (gp120M)-induced neuropathic pain in rats. ⋯ These results demonstrated that spinal Sirt3 decrease in gp120M-induced neuropathic pain was mediated by cMyc-EZH2/H3K27me3 activity in an epigenetic manner. This study provided new insight into the mechanisms of neuropathic pain in HIV patients with chronic opioids.
