Purpose: Therapeutic drug monitoring guided by the area under the concentration-time curve (AUC-guided TDM) is recommended for vancomycin. However, validated efficient software remains elusive to popularize AUC-guided TDM in Japan. The aim of this study was to validate a newly developed web application, PAT, for AUC estimation. Methods: PAT was developed on the R ver. 3.6.2 platform for use with mobile phones and personal computers. AUC estimated by PAT (AUCPAT) was evaluated against the reference AUC (AUCREF) calculated with the log-linear trapezoidal rule using eight measured concentrations, or against AUC (AUCBM-P) calculated using an evaluated available software with clinical data. Results: Investigating the best sampling points with limited sampling, PAT produced the least bias using two concentrations at 1 h and 11 h after the end of infusion (slope 1.18, intercept −15.57, median AUCPAT/AUCREF 0.93 [range 0.81–1.24]), where only one estimation (6%) was out of the predetermined acceptable range of 0.8–1.2. Employment of only a trough concentration was more biased (AUCPAT/AUCREF range 0.73–1.30 for 11 h, AUCPAT/AUCREF range 0.62–1.40 for 23 h). In comparison with the evaluated software, AUCPAT was not biased against the AUCBM-P (slope 1.04, intercept −15.80, median AUCPAT/AUCBM-P 1.00 [range 0.86–1.10]). Conclusions: The new application using two concentrations was appropriately validated and might be efficient in popularizing the AUC-guided TDM of vancomycin.
