https://www.selleckchem.com/products/r428.html The rank orders of the top five ADRs varied among the three datasets. Nausea and vomiting was the most frequent ADR in all three datasets; the remaining ADRs differed among the datasets. There were significant differences in the recording of ADRs and the frequency distributions among the three datasets. A comprehensive and reliable safety profile for post-marketing drugs should not be based on any one source. Spontaneous reports from monitoring institutions provided the most ADR data. Randomized controlled trials and case reports published in the literature can supplement the results from spontaneous reports.Vancomycin is a glycopeptide antibiotic used for the treatment of Gram-positive infections. For adult patients, treatment with vancomycin requires effective therapeutic drug-monitoring (TDM) to achieve clinical outcomes and reduce the incidence of adverse effects. However, it remains still unclear whether the TDM with vancomycin is beneficial in yielding better clinical outcomes in pediatrics. The objective of our study was to evaluate whether the clinical response to treatment was associated with initial trough concentrations of vancomycin in pediatric patients. A retrospective observation study of 60 patients (age 1 month-15 years) who had completed and qualified for analysis was conducted at Kyoto University Hospital. The response to treatment was assessed by the time to resolution of fever and time to 50% decline in C-reactive protein (CRP). In addition, we explored whether vancomycin trough level was associated with the baseline characteristics. Trend analysis showed that there were significant correlations between vancomycin trough level and age, body weight, estimated glomerular filtration rate, and serum albumin levels. The time to resolution of fever of the patients with higher initial trough level (≥ 5 µg/mL) was significantly lower than that of the patients with lower trough level ( less then  5 µg/mL). T
