The mean population PK model was used to derive the targeted PK values from 2,000 simulated patients receiving a single 1,200-mg dose of oritavancin during a 3-h infusion (assuming protein binding of 85%).
The targeted PK values for daptomycin were derived from the full prescribing information (assuming protein binding of 91.5%) (Cubicin prescribing information [http://www.cubicin.com/pdf/PrescribingInformation.pdf]).
The targeted PK values for vancomycin were obtained from reference 9.
ND, not determined.
