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
