Title: Determination of Ketoconazole in Plasma and Dosage Forms by High-Performance Liquid Chromatography and a Microbiological Method

Abstract: A simple and rapid high-performance liquid chromatographic (HPLC) method for the determination of ketoconazole in plasma and in tablets was developed. the method employs benzafibrate as internal standard and is sufficiently rapid and sensitive for use in pharmacokinetic studies. Separation of the drug from plasma was achieved by extraction with acetonitrile followed by a reversed phase chromatography on a μ Bondapak column using the isocratic mobile phase of methanol-water-glacial acetic acid (67.5:32:0.5). With this eluting solvent ketoconazole and the internal standard. were well separated from the components of plasma. A linear relationship was obtained between the ratio of the area under the peak of drug to that of the internal standard versus the concentration of the drug. Data comparing the microbiological assay with the HPLC procedure, which was developed, are shown. In the microbiological assay, Candida albicans, was the test organism, using the agar diffusion technique. Both methods were applied to the assay of ketoconazole in plasma and in tablets. Excellent agreement was observed between the results from the two methods. DOI: 10.1080/00032718908051253
