Figure 1: (A) Overlaid chromatograms (extracted at 264 nm) of (a) blank plasma (b) plasma spiked with IS (2000 ng/mL) along with RLZ (250 ng/mL) and (c) in vivo test sample taken 16 h after oral administration of RLZ (10 mg/ kg). (B) Overlaid chromatograms (extracted at 280 nm) of (a) blank plasma and (b) plasma spiked with IS (2000 ng/mL) alone and (c) plasma spiked with IS (2000 ng/mL) along with RLZ (250 ng/mL).
