Objective: We have developed an automatic vigilance system (AVS) that automatically reports adverse drug reactions (ADR) based on laboratory finding abnormalities and symptom keywords in electronic medical records. In this study, we aimed to evaluate the impact of detecting ADR using AVS on medical treatment. Methods: In AVS, drugs and their ADR signals, which would be detected and reported by AVS to pharmacists, were defined. Pharmacists evaluated the severity of these signals to identify whether these signals should be discussed with the doctor, continued to be followed up, or ignored. We investigated detection of ADR at University of Fukui Hospital between April 2016 and March 2017 along with whether prescriptions were modified because of ADR and the contribution of AVS. Assuming that ADR had worsened without appropriate treatment, medical expenses needed for treating severe ADR were calculated. Results: In total, 325 signals were defined for 146 drugs. There were 9,103 ADR signals confirmed by pharmacists for 8,531 subjects. Of these, 12 and 164 signals were discussed with the doctor and continuously observed, respectively. The pharmacist's suggestions based on AVS led to prescription modifications in 10 cases, corresponding to a reduction of 2.56 million yen in medical expenses in the event that these cases become severe. Conclusion: AVS assisted prescription revisions because of ADR and is thought to contribute to the prevention of worsening of ADR and reduction of medical expenses.

We performed a pharmacoepidemiological study on triazolam dependence with typical doses in out-patients of Fukui Medical School Hospital. We investigated the prescriptions (duration of treatment and total dose prescribed) for patients administered triazolam.The patients were classified according to the prescription pattern of this drug, Group 1: patients who had been prescribed triazolam daily, Group 2: those who had been allowed to take triazolam when they cannot sleep.Approximately 40% of all the patients had been prescribed triazolam for 8 months or longer, and were judged to be normal dose dependence. The prevalence of this dependence was apparently higher in group 1 than in group 2.

We performed a pharmacoepidemiological study on the effect of different types of questionnaires on coughing and the prevalence of this symptom in out-patients taking angiotensin converting enzyme inhibitors (ACEI) in Fukui Medical School Hospital.The following three types of quentionnaires were prepared:Type 1 ; Questionnaire asking whether the patient has a cough or no after implying that ACEI might cause this symptom.Type 2 ; Questionnaire on the general adverse effects of ACEI, including coughing.Type 3 ; Questionnaire on the general adverse effects of ACEI other than coughing.All questionnaires included a blank space in which the patients were asked to write any adverse effects. The patients were randomly divided into three groups. Each group was given one of the three questionnaires. In the type 3 questionnaire, no patient com-plained of coughing. The prevalence of cough was higher in type 1 questionnaire than in type 2 quetionnaire patients. These results indicate that the prevalence of adverse effects varies greatly depending the type of questions in the questionnaire.

A heparin lock is technique performed in order to prevent blood coagulation in the needle detained in the vessel, or a catheter. In Japan, when we perform a heparin lock, a heparin injection is diluted with physiological salt solution before use. We need to use prefilled syringes with diluted heparin. We received a sample of this product. We investigated the user-friendliness of the product. From our results, the prefilled syringe with the diluted heparin was found to be useful. Furthermore, when we use the prefilled syringe with diluted heparin, patient safety is increased.

Paclitaxel injection [NK] (PTX [NK]) is a generic of Taxol® Injection (Taxol) but no non-clinical study comparing the safety of the 2 drugs has been conducted because the active ingredient is the same.We compared the safety of PTX [NK] and Taxol in rats to see if there were any differences. PTX [NK] and Taxol were intravenously administered to CD (SD) male rats at doses of 2.0 and 4.0 mg/kg/day for 9 days. There were very slight differences in toxicological findings regarding such items as clinical observations, food consumption, gross necropsy, organ weight and histopathology. These differences, however, were generally observed after administration of a cytocidal anticancer drug. Therefore, such differences were not thought to be toxicologically significant and we concluded that the safety of PTX [NK] was no different from that of Taxol in rats.

As the effect of the filling process of portable pumps on the homogeneity of drug concentrations had not been investigated,in this study,we examined the influence of the filling process of the anticancer agent 5-fluorourcil (5-FU) and saline in this respect.We used 3 types of pump and filled the pump in 3 different ways (5-FU first and then saline,saline first and then 5-FU,and mixing 5-FU and saline beforehand and then filling).There was a significant variation in the 5-FU concentration when 5-FU and saline were added separately but the drug concentration did not vary when 5-FU and saline were mixed before filling the pumps.The result also varied with the type of pump.Our findings suggested that the drug and saline were not mixed uniformly in some types of pump when 5-FU and saline were added separately.Therefore,it is important to mix the drug and saline well before filling pumps.

During cancer chemotherapy,myelosuppression is a frequently observed toxicity manifestation which may sometimes cause severe infections.In this regard,though leukopenia-induced infections are more closely related to neutrophil counts than leukocyte counts,it is important to evaluate both leukocyte counts and neutrophil counts as markers of myelosuppression.Neutrophil counts,however,are sometimes estimated to be half leukocyte counts without conducting differential leukocyte counts.In the present study,the authors evaluated the necessity of differential leukocyte counts during cancer chemotherapy using pooled laboratory data at the University of Fukui Hospital.Variation in the percentage of neutrophils in leukocytes was observed in each leukocyte range,with the neutrophil count decreasing in pace with decreases in the leukocyte count.As an alternative index to the neutrophil count,the utility of the leukocyte count is thus considered to be low in cancer chemotherapy.There was also a divergence between adverse event grade between neutrophil and leukocyte numbers.In addition,neutrophil counts in 14.8% of the patients (26)were less than 1000/μL in spite of the fact that their leukocyte counts were higher than 3000/μL,and it was noted that 23 of them had undergone a paclitaxel-containing regimen.These results suggested that leukocyte differential counts should be measured during cancer chemotherapy,especially during the nadir period and when receiving chemotherapy containing paclitaxel.

The purpose of this study was to evaluate the quality of the original and 3 generic formulations of Iopamidol injection.To do this,the free iodine concentration and osmotic pressure were measured.In addition,impurities were tested for using high performance liquid chromatography-tandem mass spectrometry.There were no major differences between the original and generic formulations as regards free iodine concentration and osmotic pressure measurements,though one lot of the original formulation failed the free iodine concentration test.However,in the HPLC analysis,some substances not present in the original product were detected in the generic formulations.One of them was identified as DM 1/2,a substance related structurally to Iopamidol.
