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 me קרא את המסמך השלם
