Pharmacokinetics of mitomycin C in rabbit and human.

A sensitive and specific high-pressure liquid chromatographic assay was developed to characterize the plasma elimination and urinary excretion of mitomycin C in humans. Extraction of mitomycin C and an internal standard, porfiromycin, from plasma by chromatography over a non-ionic resin, Porapak Q, yields high recovery of both compounds and facilitates measurement of as little as 5 ng mitomycin C by reversed-phase high-pressure liquid chromatography. The assay was used to characterize the plasma elimination of mitomycin C in rabbits and was shown to be applicable to the characterization of the pharmacokinetics of mitomycin C in humans receiving as little as 8 mg/m2.
