Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bleomycin acts by chelating metal ions (primarily iron) and producing reactive oxygen species that cause single- and double-strand DNA breaks, leading to inhibition of DNA, RNA, and protein synthesis.
Mitomycin C is an alkylating antibiotic that inhibits DNA synthesis by forming cross-links between complementary DNA strands, thereby blocking DNA replication and transcription.
10-20 units/m2 IV, IM, or SC once weekly or twice weekly; cumulative lifetime dose should not exceed 400 units. For Hodgkin lymphoma, 10 units/m2 IV on days 1 and 15 of a 28-day cycle.
0.04 mg/kg intravenously once weekly for 4 weeks, then every 3 weeks thereafter; maximum single dose 3.5 mg.
