PPBs of plasma protein solutions spiked with VRC in vitro were grouped according to total drug concentration. ALB binding rate of samples with a higher concentration of VRC (Ct=25,000 ng/ml) was significantly higher in different protein groups (A, 30 g/L, p=0.047; 50 g/L, p=0.015). Plasma protein mixtures spiked with a higher concentration of VRC (Ct=25,000 ng/ml) had a significantly higher PPB than the lower concentration group (Ct=400 ng/ml) in both two different protein groups (D, 40.01 g/L, p<0.01; 81 g/L, p<0.01). There was no difference in AAG or GLB binding rate between different drug concentration groups (B, C).
