Itraconazole formulation studies of the melt-extrusion process with mixture design.

Bioanalytical method validation-a revisit with a decade of progress. Our data showed similar precision and accuracy within each laboratory of the three procedures used for FLC microplate preparation.

Projects and data 207766 Clinical and Laboratory Standards Institute. Stock solutions and microdilution wells were tested for concentration of antifungal agent using high-performance liquid chromatography HPLC methods previously described 125. Fluconazole trays can be accurately prepared by following ISO and serial dilution schemes.

Regarding serial 2-fold dilution procedures, better results were detected when Ido plates were prepared according to the hydrophilic rather than the hydrophobic way.

According to those standards and the ISO recommendations, the 2-fold dilutions of compounds should be performed in a multistep, rather complex, and time-consuming fashion, avoiding serial dilutions in order to prevent the risk of a systematic error being induced, for instance, by an imprecise pipette 9.

Calibration and validation – archive ISO Clinical laboratory testing and in vitro 2776 test systems — Susceptibility testing of infectious agents and evaluation of performance of antimicrobial susceptibility test devices — Part 2: Fifty microliters of the resultant mix was injected directly into the HPLC system.

In order to determine and compare the accuracy of each method described for microdilution, two consecutive HPLC determinations of the azole concentration were calculated from different wells of trays prepared according ISO recommendations, serial dilutions for hydrophobic drugs, and serial dilutions for hydrophilic compounds. Where clinical data is lacking!
