- Abstract
An initial loading procedure has been recommended to enable teicoplanin to promptly reach an effective serum concentration for the treatment of methicillin-resistant Staphylococcus aureus (MRSA). This study aimed to retrospectively evaluate the pharmacokinetics and pharmacodynamics of teicoplanin to determine the therapeutic target for the teicoplanin trough concentration and an appropriate dosing method during the first 3 days. The mean trough concentrations were 13.2 mg/L for patients with eradication of MRSA. Moreover, logistic regression analysis showed that the teicoplanin trough concentration was 13 mg/L to achieve MRSA eradication with a probability of 89.0%. The rates of achieving ≥13 mg/L in ≤24, 24–36 and ≥36 mg/kg (total dose during the first 3 days) groups were 9.1, 48.4 and 87.5%, respectively. These results suggest that the administration of ≥36 mg/kg during the first 3 days is appropriate to promptly obtain a trough concentration target of ≥13 mg/L for the initial treatment of MRSA infections.
