Özet
A reversed-phase high performance liquid chromatography (RP-HPLC) method with UV detection is described for the simultaneous determination of metronidazole and miconazole in pharmaceutical dosage forms. Chromatography was carried out on a C18 reversed-phase column, using a mixture of methanol-water (40+60, v/v) as a mobile phase, at a flow rate of 1.0 ml min-1. Sulfamethoxazole was used as an internal standard and detection was performed using a diode array detector at 254 nm. The method produced linear responses in the concentration ranges 10-70 and 1-20 μg ml-1 with detection limits 0.33 and 0.27 μg ml-1 for metronidazole and micanozole, respectively. This procedure was found to be convenient and reproducible for analysis of these drugs in ovule dosage forms. © 2002 Éditions scientifiques et médicales Elsevier SAS. All rights reserved.
