Objective: In this study, we aimed to develop a new system that can centrally manage and share drug information, and also evaluated its usefulness.Methods: Using PHP v5.3.3 as the programming language and MySQL v5.1.73 as the database, we built a web application that constantly runs on the server. Various drug information was registered in this system, and its usage status was analyzed based on the access log.Results: The system was accessed 31,678 times during the survey period (October 1 to December 31, 2019). The information sought included: basic drug information (ordering category of drugs, dosage forms and strengths, drug price, etc.) (13,962 times, 44.1%),question and answer records (7,221 times, 22.8%), pharmaceutical documents (package inserts, interview forms, documents regarding compatibility of injections, etc.) (7,172 times, 22.6%), notifications regarding new and discontinued drugs (727 times, 2.3%), websites (676 times, 2.1%), PreAVOID reports (663 times, 2.1%), pharmaceutical safety information (525 times, 1.7%), information regarding off-label drug use (409 times, 1.3%), and bibliographic information and guidelines (323 times, 1.0%). Among the users (62 pharmacists), 59.7% accessed the system only via a personal computer (PC), 38.7% via a PC and smart device (smartphone or tablet),and 1.6% via only a smart device. The median number of accesses to this system was significantly higher in pharmacists in charge of wards (190 [9-1,435]) or drug information (3,750 [2,957-5,548]) than dispensing pharmacists (68.5 [3-193]) (p＜0.001).Conclusion: This system allowed the central management and sharing of various drug information on the web, permitting access regardless of device type. Since this system was frequently used by pharmacists in charge of wards or drug information, this system was considered particularly useful in hospital pharmacist ward services and drug information services.

Introduction: Intracranial tumors cause various neurological symptoms and neuropathic pain, which are often refractory to opioids. In some of these cases, the combination of Kampo medicines can be effective. Case: The case was a 44-year-old patient who underwent surgery for a suspected papilloma. After resection, pathological examination revealed squamous cell carcinoma, positive for margins, and then, the left intraorbital metastasis was observed. Due to the intracranial invasion of the tumor, he had pain in the second and third branches of the trigeminal nerve in the left face and paresthesia in the second branch of the trigeminal nerve bilaterally (Numerical Rating Scale: NRS 10/10). Hydromorphone was introduced, and the pain was relieved, but the paresthesia remained (NRS 8/10). Both paresthesia and pain worsened during the course of chemotherapy, but MRI showed no tumor progression, thus, the cause of symptom aggravation was diagnosed edema of the tissue around the tumor. Therefore, Goreisan was started, and both paresthesia and pain were relieved. Discussion: Goreisan has been shown to be effective in cerebral edema due to its water-regulating effect by inhibiting aquaporin. In the present case, the reduction of edema in peritumoral tissues by Goreisan may have contributed to the symptomatic relief.
