Bleomycin sulfate
Bleomycin is a cystotoxic antibiotic that is used as an anticancer agent in the therapy of testicular and germ cell cancers, Hodgkin disease, lymphomas and tumors of the head and neck. Therapy with bleomycin in combination with other agents is often associated with mild-to-moderate serum enzyme elevations, but is a rare cause of clinically apparent liver injury.
