Background and Objective: With the advancement of cancer treatments and increased life expectancy, managing breakthrough cancer pain (BTcP) is essential to improve the quality of life for cancer patients. This study aimed to compare the major rapid onset opioids in Korea based on their characteristics and costs to determine the best option for each patient. Methods: Based on sales information from IQVIA-MIDAS, sublingual fentanyl tablet (SLF), fentanyl buccal tablet (FBT), and oral transmucosal fentanyl citrate (OTFC) were selected as the top three drugs for the treatment of BTcP in Korea, considering them the most comparable drugs. The cost and cost-pain relief ratio of the drugs for short-term (1 month) and long-term (1 year) treatment were compared and the ease of administration based on various factors, including pharmacokinetics, onset of action, and administration procedures were evaluated. Results: SLF was evaluated as the best overall in terms of rapid onset of action, ease of administration, and drug cost and also had the highest market share. SLF had the lowest cost pain relief ratio for both the initial and supplemental treatment for the 1-month pain intensity difference 15 (PID15) ratio. However, for the 1-month PID30 ratio, SLF was not superior to OTFC or FBT. The longer the breakthrough cancer pain duration, the more cost-effective the other rapid onset opioids. Conclusion: The rapid onset opioids that fit the patient's breakthrough cancer pain pattern have the best cost-effectiveness.

Breakthrough pain is transitory pain that occurs despite the use of opioids for background pain control. Breakthrough pain occurs in 40% to 80% of patients with cancer pain. Despite effective analgesic therapy, patients and their caregivers often feel that their pain is not sufficiently controlled. Therefore, an improved understanding of breakthrough pain and its management is essential for all physicians caring for patients with cancer. This article reviews the definition, clinical manifestations, accurate diagnostic strategies, and optimal treatment options for breakthrough pain in patients with cancer. This review focuses on the efficacy and safety of rapid-onset opioids, which are the primary rescue drugs for breakthrough pain.

Dentists often sedate patients in order to reduce their dental phobia and stress during dental treatment. Sedatives are administered through various routes such as oral, inhalation, and intravenous routes. Intravenous administration has the advantage of rapid onset of action, predictable duration of action, and easy titration. Typically, midazolam, propofol or dexmedetomidine are used as intravenous sedatives. Administration of these sedatives via infusion by using a syringe pump is more effective and successful than infusing them as a bolus. However, during intravenous infusion of sedatives or opioids using a syringe pump, fatal accidents may occur due to the clinician's carelessness. To prevent such risks, smart syringe pumps have been introduced clinically. They allow clinicians to perform effective sedation by using a computer to control the dose of the drug being infused. To ensure patient safety, various alarm features along with a drug library, which provides drug information and prevents excessive infusion by limiting the dose, have been added to smart pumps. In addition, programmed infusion systems and target-controlled infusion systems have also been developed to enable effective administration of sedatives. Patient-controlled infusion, which allows a patient to control his/her level of sedation through self-infusion, has also been developed. Safer and more successful sedation may be achieved by fully utilizing these new features of the smart pump.

목적: 돌발성 통증을 적절히 조절하는 것은 암환자에서 필수적이다. 돌발성 통증을 조절하는 것은 의료진이 돌발성 통증에 대해 잘 이해하고 적절한 구제 진통제를 사용하는 것에 달려있다. 본 연구는 한국 완화의료 전문의들의 돌발성 통증에 대한 견해와 진료 형태에 대해 알아보고자 하였다. 방법: 본 연구는 한국호스피스 완화의료학회에서 시행된 2014년 돌발성 통증 설문조사를 바탕으로 진행하였다. 100명의 의사가 온라인 설문조사에 참여하였다. 총 33개의 자가 기입식 설문 문항 중에서 12개의 항목이 분석에 사용되었다. 결과: 빠른 작용 발현은 구제 진통제를 선택함에 있어 가장 중요한 요소였다. 경구 옥시코돈(65%)과 모르핀 주사제(27%)는 흔히 사용되는 구제진통제였다. 소수의 의사들(3%)만이 점막 흡수형 펜타닐을 선호하였다. 빠른 작용 발현 때문에 경구 옥시코돈을 선택한다고 답변한 의사들은 21.5%였으며, 반면에 빠른 작용 발현 때문에 모르핀 주사제를 처방한 의사들은 81.5%였다. 전체 응답자의 약 66%는 돌발성 통증이 구제 진통제로 잘 조절되지 않는다고 답변했다. 결론: 돌발성 통증 조절에 의료진들은 어려움을 느끼고 있었고, 의료진들이 구제진통제를 선택함에 있어서 필요로 하는 중요한 요소와 실제 처방의 형태에는 차이가 있었다.

Objectives : The purpose of this case report is to examine clinical application of Traditional Korean medicine including aconitum ciliare decaisne pharmacopuncture for cancer pain caused by bone metastasis of non small cell lung cancer. Methods : The patient diagnosed as non small cell lung cancer was treated with pharmacopuncture, acupuncture, electroacupuncture and herbal medicine. We used NRS(Numeric rating scale) and ECOG PS(Eastern Cooperative Oncology Group Performance Status) to observe the effect of the treatment. Results : After the treatment, NRS of cancer pain and ECOG PS score decreased. Also, the frequency of using rapid-onset opioids decreased. Conclusions : This study suggests Traditional Korean medicine treatment including aconitum ciliare decaisne pharmacopuncture is effective in cancer pain control caused by metastasis to bone with multiple organs with non small cell lung cancer.

Background: Remifentanil, an ultra-short-acting mu-opioid receptor agonist, is unique from other opioids because of its esterase-based metabolism, minimal accumulation, and very rapid onset and offset of clinical action. Remifentanil can prevent the inflammatory response and can suppress inducible nitric oxide synthase expression in a septic mouse model. However, the effects of remifentanil on human keratinocyte and autophagy have yet to be fully elucidated during hypoxia-reoxygenation. Here we investigated whether remifentanil confers protective effect against hypoxia-reoxygenation in human keratinocyte and, if so, whether autophagy mediates this effect. Methods: The human keratinocytes were cultured under 1% oxygen tension. The cells were gassed with 94% $N_2$, and 5% $CO_2$ and incubated for 24 h at $37^{\circ}C$. To determine whether the administration of affects human keratinocytes hypoxia-reoxygenation injury, cells were then exposed to various concentrations of remifentanil (0.01, 0.1, 0.5 and 1 ng/ml) for 2 h. After remifentanil treatment, to simulate reoxygenation and recovery, the cells were reoxygenated for 12 h at $37^{\circ}C$. Control group did not receive remifentanil treatment. Normoxia group did not receive hypoxia and remifentanil treatment for 36 h. 3-MA group was treated 3-methyladenine (3-MA) for 1h before remifentanil treatment. Cell viability was measured using a quantitative colorimetric assay with MTT, showing the mitochondrial activity of living cells. Cells were stained with fluorescence and analyzed with Western blot analysis to find out any relations with activation of autophagy. Results: Prominent accumulation of autophagic specific staining MDC was observed around the nuclei in RPT group HaCaT cells. Similarly, AO staining, red fluorescent spots appeared in RPT group HaCaT cells, while the Normoxia, control and 3-MA groups showed mainly green cytoplasmic fluorescence. We here examined activation of autophagy related protein under H/R-induced cells by Western blotting analysis. Atg5, Beclin-1, LC3-II (microtubule-associated protein 1 light chain 3 form II) and p62 was elevated in RPT group cells. But they were decreased when autophagy was suppressed by 3-MA (Fig. 5). Conclusions: Although the findings of this study are limited to an in vitro interpretation, we suggest that remifentanil may have a beneficial effect in the recovery of wound from hypoxia-reoxygenation injury.
