Development and validation of a high-performance liquid chromatographic assay for the determination of fluconazole in human whole blood using solid phase extraction. Single-step iao of fluconazole from plasma by ultra-filtration for the measurement of its free concentration by high performance liquid chromatography.

In summary, our data suggest that microdilution trays for hydrophilic drugs such as FLC can be accurately prepared following the ISO recommendations or the serial 2-fold dilution schemes. All statistical analyses were done with the statistical package PAWS statistics Reference method for testing the in vitro activity of io agents against rapidly growing aerobic bacteria involved in infectious diseases.

Reference method for testing the in vitro activity of antimicrobial agents against rapidly growing anaerobic bacteria involved in infectious diseases. While this is the gold standard for preparation of dilution series, the question has risen if modern pipettes are sufficiently precise to allow dilution series to be prepared as serial dilutions without a loss of accuracy.

Sitemap Search close sitemap. Furthermore, previous studies have demonstrated a much higher interlaboratory variation in MIC results for quality control strains for itraconazole than for flucytosine and fluconazole 6 – 8. Microtiter plates were prepared according to the ISO standard and by serial dilution procedures recommended for preparation of trays of both hydrophilic and hydrophobic drugs 9 Example of a quick liquid chromatographic assay of itraconazole in serum.

HPLC is a sensitive and reproducible method for determining levels of azole components in a great variety of matrices, as has been confirmed in previous reports 12510 – 121519 – 21 Rationale documents for antifungals Please review our privacy policy. The method was validated by performing three calibration curves on consecutive days. General Committee to Regarding serial 2-fold dilution procedures, better results were detected when FLC plates were prepared according to the hydrophilic rather than the hydrophobic way.
