ACTION AND CLINICAL PHARMACOLOGY
Mitomycin was first investigated 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. There is a
correlation between
the guanine and cytosine content of DNA and the degree of
mitomycin-induced cross-linking. At
high concentrations of the drug, cellular RNA and protein synthesis
are also suppressed.
In humans, mitomycin is rapidly cleared from the plasma after
intravenous administration with a
biphasic plasma elimination curve. Time required to reduce the serum
concentration by 50%
after a 30 mg bolus injection, is 17 minutes. After injection of 30
mg, 20 mg or 10 mg
intravenously, the maximal serum concentrations were 2.4 µg/mL, 1.7
µg/mL and 0.52 µg/mL,
respectively.
In general, the smaller the dose, the more rapidly blood levels of
mitomycin decreased.
Clearance is affected primarily by metabolism in the liver, but
metabolism occurs in other tissues
as well.
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
administered mitomyc
