Abstract:

A validated HPLC method for the simultaneous determination of diminazene diaceturate and phenazone has been established for the analysis of the compounds in veterinary granules for injection and in bulk powders. The compounds were separated using a Symmetry RP 18 analytical column and detected by UV absorbance at 250 nm. Linearity, accuracy as well as the intra-assay precision, inter-day precision and specificity of the method were established. The limits of detection and quantification were 3.2 and 9.7 µg mL-1 for diminazene diaceturate and 9.57 and 28.99 µg mL-1 for phenazone. Method had the potential to determine these drugs simultaneously from dosage forms without any interference with each other.
