Determination of pentamidine in whole blood, plasma, and urine by high-performance liquid chromatography.
The analysis of pentamidine in whole blood, plasma, and urine by liquid chromatography is described. Extraction was made with a mixture of acetonitrile and chloroform followed by back-extraction into phosphate buffer. A reversed-phase chromatographic system with fluorescence detection was used. The precision of the method was 5-7% at the lower limit of determination (16 nmol/L in plasma and hemolyzed whole blood, 27.7 nmol/L in urine).
