Zoster sine herpete: An atypical presentation of herpes zoster without rash (ASRA-FALL 2025) - "Of note, they were recently diagnosed with pneumonitis concomitant with severe persistent asthma by a pulmonologist and were on week four of a prednisone taper and trimethoprim-sulfamethoxazole regimen...They were also prescribed lidocaine 5% ointment and advised to continue their chronic pain regimen consisting of tapentadol extended-release 50 mg two times daily to provide neuropathic and nociceptive pain control in addition to acetaminophen, celecoxib, 1% diclofenac gel, and cyclobenzaprine...Discussion ZSH is an important diagnosis to consider for immunocompromised patients presenting with acute, localized, dermatomal pain without skin changes or a clear, identifiable source. Similar to HZ, ZSH treatment includes antivirals like valacyclovir or acyclovir alongside analgesics.2,4,5 Prevention also plays an important role with the herpes zoster vaccine given as a two-dose series.1,4 While rare, prompt diagnosis and timely treatment of ZSH are crucial to avoid..."

Comprehensive insights into diabetic peripheral neuropathy: pathophysiology and therapeutic approaches. (PubMed, J Diabetes Metab Disord) - "The United States Food and Drug Administration has approved pharmacological treatments for painful diabetic peripheral neuropathy: pregabalin, duloxetine, gabapentin, extended-release tapentadol, tramadol, and the capsaicin 8% patch. Non-Food and Drug Administration-approved therapies, such as amitriptyline and the 5% lidocaine patch, are also widely used...A multifaceted approach incorporating pharmacological and non-pharmacological therapies is essential for optimizing patient outcomes in diabetic peripheral neuropathy. Targeting underlying pathophysiological mechanisms while providing symptomatic relief can enhance treatment efficacy and improve the quality of life for individuals with diabetic peripheral neuropathy."

Decline and Pronounced Regional Variation in Tapentadol Use in the US (APA 2025) - "While much research has focused on opioids like fentanyl and hydrocodone, less is known about tapentadol, an atypical opioid. Tapentadol extended-release (ER), approved in 2013 for diabetic neuropathy-related chronic pain, is not recommended by the American Diabetes Association due to addiction risk and modest pain relief... Tapentadol accounted for 1.3% of Schedule II opioids by morphine milligram equivalents in 2020. Distribution was higher in the South Atlantic (29.0 mg/person) and East South Central (28.8 mg/person) regions compared to the Pacific (12.9 mg/person) and New England (12.8 mg/person). Nationally, tapentadol use declined by 53.8% between 2012 and 2020, with New Hampshire being the only state showing an increase (+13.1%)."

Tapentadol: A Comprehensive Review of Its Role in Pain Management. (PubMed, Cureus) - "Approved by the FDA in 2008 for immediate release and in 2011 for extended release, tapentadol effectively addresses both nociceptive and neuropathic pain, offering a more favorable efficacy-safety profile compared to traditional opioids such as tramadol. Additionally, tapentadol is gaining recognition as a preferred option for managing significant pain in cancer patients due to its effectiveness and reduced side effects. This review evaluates tapentadol's clinical and pharmacological attributes, systematically analyzing literature on its efficacy, safety, pharmacokinetics, and comparative effectiveness, suggesting that tapentadol is a viable option for effective pain management with potential for broader clinical applications."

Appropriate use of tapentadol: focus on the optimal tapering strategy. (PubMed, Curr Med Res Opin) - "Studies for this narrative review were identified via PubMed using a structured search strategy, focusing on management of chronic non-cancer pain with opioids, and the efficacy, tolerability, and pharmacology of tapentadol prolonged release. While tapentadol is associated with a low frequency of opioid withdrawal symptoms after abrupt discontinuation, use of a tapering strategy is prudent. Tapering strategies developed for opioids in general can potentially be safely individualized in tapentadol-treated patients, although research on tapering strategies for tapentadol is required."

Influence of tapentadol and oxycodone on the spinal cord and brain using electrophysiology - a randomized, placebo-controlled trial. (PubMed, Br J Clin Pharmacol) - "A decrease in the number of nociceptive withdrawal reflex was observed during tapentadol treatment, possibly relating to the noradrenaline reuptake inhibition effects on the spinal cord. Both oxycodone and tapentadol affected cortical measures possible due to μ-opioid receptor agonistic effects evident in the dipole sources, with the strongest effect being mediated by oxycodone. These findings could support the dual effect analgesic mechanisms of tapentadol in humans as previously shown in preclinical studies."
