TLC-spectrodensitometric method for simultaneous determination of dapagliflozin and rosuvastatin in rabbit plasma: stability indicating assay and kinetic studies.

ABSTRACT: Herein, a sensitive and reliable eco-friendly TLC-spectrodensitometric method has been established for the simultaneous determination of dapagliflozin (DAPA) and rosuvastatin (ROSV) for the first time. TLC separation was carried out on silica gel F₂₅₄ using ethyl acetate : methanol (5 : 0.1, v/v) as a mobile phase and UV measurement at 243 nm. The method was fully validated according to ICH guidelines. Acceptable separation was achieved with R _f values of 0.23 and 0.44 for DAPA and ROSV, respectively. Regression plots revealed linear relationships in the concentration range 20-2500 ng per band and 10-2500 ng per band with LODs of 6.60 and 3.57 ng per band for both DAPA and ROSV, respectively. The relative standard deviations (RSDs%) were found to be 1.35 and 0.
