Objective.
To develop and compare HPLC-DAD and UHPLC-UV assays for the quantitation of posaconazole in bulk powder and suspension dosage form.
Methods.
Posaconazole linearity range was 5–50 μg/mL for both assays.
For HPLC-DAD assay, samples were injected through Zorbax SB-C18 (4.6 × 250 mm, 5 μm) column.
The gradient elution composed of the mobile phase acetonitrile: 15 mM potassium dihydrogen orthophosphate (30 : 70 to 80 : 20, linear over 7 minutes) pumped at 1.5 mL/min.
For UHPLC-UV assay, samples were injected through Kinetex-C18 (2.1 × 50 mm, 1.3 μm) column.
The mobile phase composed of acetonitrile: 15 mM potassium dihydrogen orthophosphate (45 : 55) pumped isocratically at 0.4 mL/min.
Detection wavelength was 262 nm in both methods.
Results.
The run time was 11 and 3 minutes for HPLC-DAD and UHPLC-UV assays, respectively.
Both assays were linear ( r 2 > 0.999 ) with CV% and % error of the mean <3%.
Limits of detection and quantitation were 0.82 and 2.73 μg/mL for HPLC-DAD and 1.04 and 3.16 μg/mL for UHPLC-UV, respectively.
The methods quantitated PSZ in suspension dosage form with no observable interferences.
Conclusions.
Both assays were proven sensitive and selective according to ICH guidelines.
UHPLC-UV assay exhibited some economic and chromatographic separation superiority.
