The development of a specific agar diffusion bioassay for the quantitative determination of fluconazole formulated in capsules was carried out using a strain of Candida albicans ATCC 18804 as the test organism. A prospective validation of the method showed adequate linearity (r²=0.9995), precision (R.S.D. = 4.0% for intra-day and 4.5% for inter-day precision) and accuracy (mean recovery = 102.9%). High performance liquid chromatography was chosen as a comparison method for the fluconazole determination. The contents of fluconazole determined by both methods, for four capsule samples, showed a strong correlation, confirmed by Pearson's correlation coefficient value (r = 0.9884). The bioassay is a suitable method for both research and pharmaceutical industry... |
