ACTIONS AND CLINICAL PHARMACOLOGY
Mitomycin was investigated at first as an antibiotic in Japan. It was
then found to be active as an
antineoplastic agent. It selectively inhibits the synthesis of
deoxyribonucleic acid (DNA). The exact point
of mitomycin attachment to DNA remains unknown. At high concentrations
of the drug, cellular RNA and
protein synthesis are also suppressed.
Mitomycin is rapidly cleared from the plasma after intravenous
administration with a biphasic plasma
elimination curve. Mitomycin is widely distributed but does not appear
to cross the blood brain barrier.
After intravenous injection of 30, 20 or 10 mg of mitomycin, the
maximal serum concentrations were 2.4,
1.7 and 0.52
:
g/mL respectively. Serum half-life after a 30 mg bolus injection is 17
minutes. Clearance is
effected primarily by metabolism in the liver, but metabolism occurs
in other tissues as well. In general, the
smaller the dose, the more rapidly blood levels of mitomycin
decreased.

Approximately 10% of a dose of mitomycin is excreted unchanged in the
urine. Since metabolic pathways
are saturated at relatively low doses, the percent of a dose excreted
in urine increases with increasing doses.
In children, excretion of intravenously administer
