Disaster after the plaster. Fentanyl withdrawal symptoms in a curable hospice patient

Another lesson from the earthquake: Transdermal fentanyl dependence in two child victims

Thousands died in the Kahramanmaraş-centered earthquake in February 2023, and even more were injured. Some were administered transdermal fentanyl patches (TFPs) due to severe pain. Two pediatric patients, both severely injured victims of the earthquake, developed dependence on TFPs and experienced difficulties during the cessation of fentanyl treatment. The first child was discharged while still being administered fentanyl after four months. In the second case, TFPs could be ceased after four months. This study aimed to emphasize that TFPs can lead to dependence in pediatric patients as well; hence, they should be used more carefully to avoid any potential dependency.

Opioid withdrawal symptoms, a consequence of chronic opioid use and opioid use disorder: Current understanding and approaches to management

WHAT IS KNOWN AND OBJECTIVE

Opioid use in the United States has reached unprecedented-some would even say crisis-levels. Although many individuals use opioid drugs as part of legitimate pain management plans, a significant number misuse prescription or illicit opioids. With regular opioid use, individuals develop tolerance and physical dependence; both are predictable, physiologic responses to repeated opioid exposure. However, a substantial number of individuals who misuse opioids will develop opioid use disorder (OUD), a complex, primary, chronic, neurobiological disease rooted in genetic, environmental and psychosocial factors. This article discusses OUD, opioid receptor physiology, and opioid withdrawal symptomatology and pathophysiology, as well as current treatment options available to reduce opioid withdrawal symptoms in individuals with physical dependence and/or OUD.

METHODS

The research articles regarding OUD and its management have been reviewed thoroughly based on a PubMed literature search using keywords related to opioid dependence, its pathophysiology and current treatment strategies.

RESULTS AND DISCUSSION

Tolerance/physical dependence and the behavioural characteristics associated with OUD reflect complex neurobiologic adaptations in several major systems of the brain, including the locus ceruleus and mesolimbic systems. Physical dependence is responsible for the distressing withdrawal symptoms individuals experience upon abrupt cessation or rapid dose reduction of exogenous opioids. Opioid withdrawal symptoms are a key driver behind continued opioid use, and a barrier to opioid discontinuation. Several opioid-based medications are available to treat patients with OUD; these treatments can diminish opioid withdrawal symptoms and cravings as well as block opioid effects in the event of relapse. Additionally, non-opioid drugs may be used during acute detoxification to help alleviate opioid withdrawal symptoms.

WHAT IS NEW AND CONCLUSION

The opioid crisis has produced many challenges for physicians, one being the need to determine which patients would benefit most from maintenance therapy and which may be candidates for opioid discontinuation. In addition to summarizing current understanding of OUD, we provide a new algorithm for determining the need for continued opioid use as well as examples of situations where management of opioid withdrawal symptoms is indicated.

Efficacy and safety of transdermal fentanyl for the treatment of oral mucositis pain caused by chemoradiotherapy in patients with esophageal squamous cell carcinoma

PURPOSE

Oral mucositis is one of the most painful side effects found in esophageal squamous cell carcinoma (ESCC) patients treated with chemoradiotherapy. The transdermal route of administration is worthy of investigation for patients who suffer from dysphagia due to severe oral mucositis. In this phase 2 study, we investigated the efficacy and safety of transdermal fentanyl (TDF) for mucositis pain caused by chemoradiotherapy in ESCC patients.

METHODS

Forty-six ESCC patients who experienced moderate to severe oral mucosal pain during chemoradiotherapy received TDF for pain relief. The assessment of pain was made according to the Numeric Rating Scale (NRS). Efficacy and safety of TDF was collected and conducted in an open-label fashion. The analgesic effect, quality of life, and side effects were evaluated after the administration of transdermal fentanyl using the paired sample Wilcoxon signed rank test.

RESULTS

The mucositis-induced pain disappeared in 31 (67.4 %) patients during the treatment with transdermal fentanyl with the median time of onset at day 6.6 (range 3-14). The median Numeric Rating Scale (NRS) score was reduced from 6 (range 3-9) before treatment to 4.5 (range 2-9), 3 (range 2-8), 2.5 (range 1-8), 2 (range 0-6), and 0 (range 0-4) on days 3, 6, 9, 11, and 15, respectively, after treatment (P < 0.001). The patients' quality of life also improved significantly (P < 0.01). The side effects of treatment were mild and disappeared within several days.

CONCLUSION

Transdermal fentanyl is an effective, convenient, and well-tolerated treatment for mucositis pain caused by chemoradiotherapy, which can improve ESCC patients' quality of life.
