Abstract:
Micellar mobile phase was utilized for the separation and quantification of two antimicrobial mixtures with some analgesics that were found to augment their antimicrobial activity, namely; cefotaxime sodium (CFX) with ibuprofen (IBU) and naproxen (NPX) (mixture Ι), and azithromycin dihydrate (AZT) with diclofenac sodium (DIC) (mixture ΙΙ). Both mixtures were analyzed using a C18 column operated at 50 °C using a mobile phase composed of sodium dodecyl sulphate (SDS), an organic modifier; (1-propanol or acetonitrile), and 0.3% triethylamine (TEA), adjusting pH to the required value with 2 M orthro-phosphoric acid, accompanied with UV detection. The proposed method was subjected to full validation procedure and was applied to determine the concentration of the studied antibiotics in homogenized liver, kidney and heart rat tissue samples, with or without the co-administered non steroidal anti-inflammatory drugs.
