Objective: Our previous study reported many technical alarms in the dispensing inspection support system due to setting or operation errors, but not due to dispensing errors, and that countermeasures reduce technical alarms. In this study, we investigated the long-term effects of the countermeasures.Methods: The log data of the inspection results were extracted from the dispensing inspection support system and divided into image inspection and weight inspection data. The details and frequency of technical alarms before (April-June 2019), after (April-June 2020), and one year after (April-June 2021) the countermeasures were compared by chi-square test.Results: The frequency of technical alarms in image inspection was 13.7, 11.3, and 9.1% in 2019, 2020, and 2021, respectively (p< 0.01). However, the frequency of technical alarms in weight inspection was 3.0, 3.0, and 1.6% in 2019, 2020, and 2021,respectively (p< 0.01). The ratio of technical alarms to all alarms was 98.2% for image inspections and 91.2% for weight inspections in 2021.Conclusion: The frequency of technical alarms was reduced by the countermeasures. However, the ratio of technical alarms to all alarms is still high, and further improvements are needed to prevent the loss of reliability due to technical alarms.

Background/Aims: 5-Aminosalicylic acid (ASA) causes intolerance reactions in some patients. This study was performed to examine the prognosis of patients with ulcerative colitis (UC) and 5-ASA intolerance, and to evaluate the potential interaction between 5-ASA intolerance and the intestinal microbiota. Methods: We performed a retrospective cohort study of patients with UC who visited participating hospitals. The primary endpoint was to compare the incidence of hospitalization within 12 months between the 5-ASA intolerance group and the 5-ASA tolerance group. The secondary endpoint was to compare the risk of adverse clinical outcomes after the start of biologics between the 2 groups. We also assessed the correlation between 5-ASA intolerance and microbial change in an independently recruited cohort of patients with UC. Results: Of 793 patients, 59 (7.4%) were assigned to the 5-ASA intolerance group and 734 (92.5%) were assigned to the 5-ASA tolerance group. The admission rate and incidence of corticosteroid use were significantly higher in the intolerance than tolerance group (P< 0.001). In 108 patients undergoing treatment with anti-tumor necrosis factor biologics, 5-ASA intolerance increased the incidence of additional induction therapy after starting biologics (P< 0.001). The 5-ASA intolerance group had a greater abundance of bacteria in the genera Faecalibacterium, Streptococcus, and Clostridium than the 5-ASA tolerance group (P< 0.05). Conclusions In patients with UC, 5-ASA intolerance is associated with a risk of adverse clinical outcomes and dysbiosis. Bacterial therapeutic optimization of 5-ASA administration may be important for improving the prognosis of patients with UC.

Objective: In many medical institutions in Japan, 10% lidocaine gel is prepared as an in-hospital formulation to treat intractable neuropathic pain. Clinical studies have reported the short-term efficacy of topical lidocaine therapy for neuropathic pain, while there are few reports in real-world practice. To clarify the clinical usage and its usefulness, in this study, we investigated the duration of use, amount, effectiveness, and safety of 10% lidocaine gel.Design: We conducted a retrospective study investigating the actual usage of 10% lidocaine gel using electronic medical records.Methods: This study included 74 patients treated with 10% lidocaine gel in Kyoto University Hospital between July 2019 and January 2022. Information about disease (purpose of use), concomitant medications and other background information of the patients were collected. In addition, the duration of use, amount, adverse events, and discontinuation of 10% lidocaine gel were investigated. Effectiveness was determined by physician interviews and the pain visual analogue scale (VAS).Results: Ten percent lidocaine gel was used primarily to treat postherpetic neuralgia and, in some cases, other types of chronic pain for a median duration of use of 3.2 months (0.03-118.5). Pain relief was achieved in 73.3% of patients according to physician interviews, with a significant decrease in the VAS score. Although adverse events were observed in 12 patients (16.2%), including skin problems (12.2%), paralysis (4.1%), and somnolence (1.4%), eight patients continued to use 10% lidocaine gel after their occurrence. Three patients discontinued it due to adverse events, and their symptoms subsequently improved thereafter.Conclusion: The present results suggest that 10% lidocaine gel is effective and safe even when used for a long-time. Although this is a single-center study, it is the first systematic investigation of real-world usage of an in-hospital formulation of 10% lidocaine gel and is expected to assist clinical practice and drug development.

Objective: In patients with specific backgrounds, comprehensive identification of health problems and proactive pharmacist intervention are crucial to providing safe and effective medical care. However, there are insufficient reports on chemotherapy regimen selection and supportive care management in patients taking immunosuppressants. In this study, to circumvent adverse events, pharmacists intervened with a patient administering tacrolimus (TAC) using known information, focusing on multiple factors attributable to the patient in addition to drug interactions.Methods: The patient was a male in their 70s who received palliative chemotherapy for gastric cancer during their dermatomyositis treatment with TAC. Pharmaceutical support for cancer chemotherapy was provided using the following four procedures: (1) Patient information was collected from interviews and electronic medical records to identify patient-specific problems; (2) Basic pharmacological information was collected from tertiary sources, focusing on the interaction between TAC and aprepitant (APR). Furthermore, clinical reports were collected, and the pharmacokinetic drug interaction significance classification system was used for quantitative predictions; (3) The information obtained in steps 1) and 2) was evaluated, and comprehensive proposals linked to the patient information were presented; (4) Adverse events, TAC blood level, and patient outcomes were monitored after treatment initiation.Results: A chemotherapy regimen consisting of S-1/oxaliplatin therapy without APR was selected. The adverse effects were controllable, and the treatment was completed without many adverse events. Meanwhile, TAC adherence was unaffected by cancer chemotherapy, and the TAC blood concentration or dose ratios were controlled within the same range as previously reported.Conclusion: In cancer chemotherapy, for cases with limited evidence or information, comprehensive pharmaceutical support was provided using known patient information, considering multiple patient factors. This report is beneficial as an example of supportive care management by a pharmacist and contributes to providing optimal service in cases with specific backgrounds.
