Questions & Answers

Side Effects & Adverse Reactions

Patients receiving bleomycin must be observed carefully and frequently during and after therapy. It should be used with extreme caution in patients with significant impairment of renal function or compromised pulmonary function.

Pulmonary toxicities occur in 10% of treated patients. In approximately 1%, the nonspecific pneumonitis induced by bleomycin progresses to pulmonary fibrosis and death. Although this is age and dose related, the toxicity is unpredictable. Frequent roentgenograms are recommended (see ADVERSE REACTIONS, Pulmonary).

A severe idiosyncratic reaction (similar to anaphylaxis) consisting of hypotension, mental confusion, fever, chills, and wheezing has been reported in approximately 1% of lymphoma patients treated with bleomycin. Since these reactions usually occur after the first or second dose, careful monitoring is essential after these doses (see ADVERSE REACTIONS, Idiosyncratic Reactions).

Renal or hepatic toxicity, beginning as a deterioration in renal or liver function tests, have been reported. These toxicities may occur at any time after initiation of therapy.

Usage in Pregnancy
Pregnancy Category D

Bleomycin can cause fetal harm when administered to a pregnant woman. It has been shown to be teratogenic in rats. Administration of intraperitoneal doses of 1.5 mg/kg/day to rats (about 1.6 times the recommended human dose on a unit/m2 basis) on days 6 to 15 of gestation caused skeletal malformations, shortened innominate artery and hydroureter. Bleomycin is abortifacient but not teratogenic in rabbits at intravenous doses of 1.2 mg/kg/day (about 2.4 times the recommended human dose on a unit/m2 basis) given on gestation days 6 to 18.

There have been no studies in pregnant women. If bleomycin is used during pregnancy, or if the patient becomes pregnant while receiving this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant during therapy with bleomycin.

Uses

Bleomycin for Injection USP should be considered a palliative treatment. It has been shown to be useful in the management of the following neoplasms either as a single agent or in proven combinations with other approved chemotherapeutic agents:

Squamous Cell Carcinoma

Head and neck (including mouth, tongue, tonsil, nasopharynx, oropharynx, sinus, palate, lip, buccal mucosa, gingivae, epiglottis, skin, larynx), penis, cervix, and vulva. The response to bleomycin is poorer in patients with previously irradiated head and neck cancer.

Lymphomas

Hodgkin's Disease, non-Hodgkin's lymphoma.

Testicular Carcinoma

Embryonal cell, choriocarcinoma, and teratocarcinoma.

Bleomycin for injection has also been shown to be useful in the management of:

Malignant Pleural Effusion

Bleomycin for injection is effective as a sclerosing agent for the treatment of malignant pleural effusion and prevention of recurrent pleural effusions.

History

There is currently no drug history available for this drug.

Other Information

Bleomycin for Injection USP is a mixture of cytotoxic glycopeptide antibiotics isolated from a strain of Streptomyces verticillus. It is freely soluble in water. Bleomycin for Injection USP contains sterile bleomycin sulfate equivalent to 15 units or 30 units of bleomycin. Sulfuric acid or sodium hydroxide can be used, if necessary, to adjust pH.

Bleomycin for Injection USP may be given by the intramuscular, intravenous or subcutaneous routes.

Its chemical name is N’-[3-(dimethylsul-phonio)propyl]bleomycin-amide (bleomycin A2) and N’-[4-(guaniodobutyl)]bleomycin-amide (bleomycin B2). (Main component: Bleomycin A2, in which R is [CH3]2S+CH2CH2CH2-)

The molecular formula of bleomycin A2 is C55H84N17O21S3 and a calculated molecular weight of 1414. The molecular formula of bleomycin B2 is C55H84N20O21S2 and a calculated molecular weight of 1425. The structural formula of bleomycins A2 and B2 are shown below.

Structural Formula

Note: A unit of bleomycin is equal to the formerly used milligram activity. The term milligram activity is a misnomer and was changed to units to be more precise.
