A rapid, sensitive, specific liquid chromatographic method has been developed for the determination of therapeutic levels of ganciclovir in human plasma.
Plasma (1 ml) and acyclovir (I.S.) were treated with 50% trichloroacetic acid. The supernatant was neutralized with 2 M NaOH and purified with chloroform. The aqueous phase (80 microl) was analyzed by a 3-microm Hypersil ODS C18 column with 0.04 M triethylamine-0.1 M sodium dihydrogen phosphate monohydrate as the mobile phase (1 ml/min) and ultraviolet detection at 254 nm.
Calibration was linear from 50 to 10000 ng/ml. Intra- and inter-day C.V. did no exceed 6.65%. The detection limit was about 10 ng/ml.
