Warnings/Precautions |
|
The U.S. Food and Drug Administration (FDA) currently recommends that
procedures for proper handling and disposal of antineoplastic agents be
considered. Occurrence of pulmonary fibrosis is higher in elderly patients and
in those receiving >400 units total and in smokers and patients with prior
radiation therapy. A severe idiosyncratic reaction consisting of hypotension,
mental confusion, fever, chills and wheezing (similar to anaphylaxis) has been
reported in 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. Check lungs prior to each treatment for fine rales
(1st sign). Follow manufacturer recommendations for administering 02
during surgery to patients who have received bleomycin. |

Adverse
Reactions |
|
>10%:
Cardiovascular: Raynaud's phenomenon
Central nervous system: Mild febrile reaction, fever, chills, patients may
become febrile after intracavitary administration
Dermatologic: Pruritic erythema
Integument: ~50% of patients will develop erythema, induration, and
hyperkeratosis and peeling of the skin; hyperpigmentation, alopecia, nailbed
changes may occur; this appears to be dose-related and is reversible after
cessation of therapy
Irritant chemotherapy
Gastrointestinal: Mucocutaneous toxicity, stomatitis, nausea, vomiting,
anorexia
Emetic potential: Moderately low (10% to 30%)
Local: Phlebitis, pain at tumor site
1% to 10%:
Dermatologic: Alopecia
Gastrointestinal: Weight loss
Respiratory: Toxicities (usually pneumonitis) occur in 10% of treated
patients; 1% of patients progress to pulmonary fibrosis and death
Miscellaneous: Idiosyncratic: Similar to anaphylaxis and occurs in 1% of
lymphoma patients; may include hypotension, confusion, fever, chills, and
wheezing. May be immediate or delayed for several hours; symptomatic treatment
includes volume expansion, pressor agents, antihistamines, and steroids
<1%: Myocardial infarction, cerebrovascular accident, skin
thickening,scleroderma-like skin changes, hepatotoxicity, renal toxicity;
respiratory effects are dose-related when total dose is >400 units or with
single doses >30 units; pathogenesis is poorly understood, but may be related
to damage of pulmonary, vascular, or connective tissue; manifested as an acute
or chronic interstitial pneumonitis with interstitial fibrosis, hypoxia, and
death; symptoms include cough, dyspnea, and bilateral pulmonary infiltrates
noted on CXR; it is controversial whether steroids improve symptoms of bleomycin
pulmonary toxicity; tachypnea, rales
Myelosuppressive:
WBC: Rare
Platelets: Rare
Onset (days): 7
Nadir (days): 14
Recovery (days): 21 |

|
|
Overdosage/Toxicology |
|
Symptoms of overdose include chills, fever, pulmonary fibrosis,
hyperpigmentation |

|
|
Drug
Interactions |
|
Decreased effect:
Digitalis glycosides: May decrease plasma levels and renal excretion of
digoxin
Phenytoin: Results in decreased phenytoin levels, possibly due to decreased
oral absorption
Increased toxicity: Cisplatin: Results in delayed bleomycin elimination due
to decrease in creatinine clearance secondary to cisplatin |

|
|

|
|
Mechanism of
Action |
|
Inhibits synthesis of DNA; binds to DNA leading to single- and double-strand
breaks; isolated from Streptomyces verticillus |

|
|
Pharmacodynamics/Kinetics |
|
Absorption: I.M. and intrapleural administration produces serum
concentrations of 30% of I.V. administration; intraperitoneal and S.C. routes
produce serum concentrations equal to those of I.V.
Distribution: Vd: 22 L/m2; highest concentrations seen
in skin, kidney, lung, heart tissues; low concentrations seen in testes and GI
tract; does not cross blood-brain barrier
Protein binding: 1%
Metabolism: By several tissue types, including the liver, GI tract, skin,
lungs, kidney, and serum
Half-life (biphasic): Dependent upon renal function:
Normal renal function:
Initial: 1.3 hours
Terminal: 9 hours
End-stage renal disease:
Initial: 2 hours
Terminal: 30 hours
Time to peak serum concentration: I.M.: Within 30 minutes
Elimination: 50% to 70% of dose excreted in urine as active drug; not removed
by hemodialysis |

|
|
Usual Dosage |
|
Refer to individual protocols; 1 unit = 1 mg
Children and Adults:
Test dose for lymphoma patients: I.M., I.V., S.C.: Because of the possibility
of an anaphylactoid reaction, less than or equal to 2 units of bleomycin for the
first 2 doses; monitor vital signs every 15 minutes; wait a minimum of 1 hour
before administering remainder of dose; if no acute reaction occurs, then the
regular dosage schedule may be followed
Single-agent therapy:
I.M./I.V./S.C.: Squamous cell carcinoma, lymphoma, testicular carcinoma:
0.25-0.5 units/kg (10-20 units/m2) 1-2 times/week
CIV: 15 units/m2 over 24 hours daily for 4 days
Combination-agent therapy:
I.M./I.V.: 3-4 units/m2
I.V.: ABVD: 10 units/m2 on days 1 and 15
Maximum cumulative lifetime dose: 400 units
Dosing adjustment in renal impairment:
Clcr 10-50 mL/minute: Administer 75% of normal dose
Clcr <10 mL/minute: Administer 50% of normal dose
Hemodialysis: None
CAPD effects: None
CAVH effects: None
Adults: Intracavitary injection for malignant pleural effusion: 60
international units (range of 15-120 units; dose generally does not exceed 1
unit/kg) in 50-100 mL SWI |
