An initial dosing method for teicoplanin based on the area under the serum concentration time curve required for MRSA eradication

Teicoplanin is a glycopeptide antibacterial agent that has a long serum half-life and therefore takes time to achieve steady-state conditions. An appropriate initial dosing is needed for teicoplanin to promptly reach an effective serum trough concentration. However, little information is available on tailoring the initial dosing for patients with various characteristics. The objective of this study was to develop a nomogram for determining teicoplanin initial dose to promptly reach an effective trough concentration (≥ 13 μg/mL). A logistic regression analysis was performed to test whether the area under the concentration time curve (AUC) is a significant predictor of microbiological response (persistence 0; eradication 1). The study included 24 adult patients with methicillin-resistant Staphylococcus aureus infections [minimal inhibitory concentration (MIC) for the isolates was
