Pharmacokinetic studies of alpha-difluoromethylornithine in rabbits using an enzyme-linked immunosorbent assay.
Using an inhibition immunoassay, the pharmacokinetics of DFMO have been evaluated. After intravenous infusion, DFMO concentration in serum is observed to reach a maximum after 2-3 h followed by a decrease. This profile is consistent with the formation of a covalent adduct between DFMO and the enzyme which it irreversibly inhibits. The adduct was isolated by immunoaffinity chromatography.
